INTRODUCTION

Methods for Irrigation and Agriculture (MIRRA) and Massachusetts Institute of Technology (MIT) have been working with three farms to conduct its prototype testing for the ultra-low energy drip emitters.

Looking back at this past year, testing has revealed the emitter’s strengths as well as areas for improvement. At Ramtha, the MIRRA team was happy to see that the emitters were operating successfully with treated wastewater. Treated wastewater in an irrigation system typically poses one particular problem: clogging. It is for this reason that farmers tend to avoid using online emitters in irrigation. However, the teams have now demonstrated to farmers that these emitters can play a role in mingling treated waste water with irrigation systems in Jordan. At Sharhabeel, the farm’s main crops are fruit-bearing trees. When installing the emitters, the MIRRA team used micro tubing – a circular tube surrounding the tree with five drippers who resulted in improved crop conditions a few months following installation. NCARE was pleased with the outcomes of the crops paired with micro tubing, compared to the other irrigation setups at the station. In the north of Jordan, Mafraq gave a different perspective. It is here that olive trees are cultivated in the desert climate of Mafraq. Growing the olive trees in this context revealed several challenges that the MIRRA team is to avoid in the future: the difficulty of cultivating this water-thirsty crop in this area as well as reconsidering this site as not well suited for the project. Across the board, MIRRA has been busy at the participating sites, optimizing the farms to resolve issues and produce accurate Uniformity Tests. In October and November, now that the sites have been standardized and initial obstacles in operations and testing have been resolved, the Uniformity Tests have yielded conclusive results of the emitters’ performance. The next stage of the project is underway as MIRRA hosted a “Field Day “in Sharhabeel (November 6th, 2017). The Field Day was a chance for team members to demonstrate the advantages of MIT’s low-pressure emitters. The farmers that attended had the opportunity to partner with MIRRA, adopt the technology and retrofit their current irrigation system. In this way, both MIRRA and the farmers are to be able to observe the emitters’ performance. The aim is to have additional farmers involved in the project by the next irrigation year – March 2018. The following is a look back at the work and progress made at each site followed up by the activities conducted during the MIT’s visit to Jordan in September.

SHARHABEEL STATION (Sites 11 – 14)

Sharhabeel bin Hasanah Station is managed by the National Center for Agricultural Research and Extension (NCARE) and is located in the Jordan Valley covering an area of 101 dunum.

MIRRA chose two sites to utilize to test MIT’s emitters: the

Orange orchard (Site ID 11 and 12) and the Pomegranate orchard (Site ID 13 and 14). Work started at Sharhabeel on May 1. The local ADRITIC

Company designed and installed the drip irrigation system. During the course of this work, an electric 2 horsepower pump, disk filter, sand filter, controller, a pump relay and reducers were installed at the farm.

The irrigation system was completed following several adaptations carried out on May 15. MIRRA made numerous visits to the station to conduct uniformity tests, monitor the irrigation system and observe its operation. On July 10, the pressure gauges were replaced when they were not producing accurate results. Later, the data logger also needed replacement at site 11. It was discovered that the data logger had a broken piece and needed replacement.

By July 25, the MIRRA team headed out to the station as a group of four in order to conduct the Uniformity Test for the same plot together (Citrus plot, MIT & Traditional). It was noted that there was a problem with the pump’s pressure. ADRITIC was contacted to resolve the problem. The pump was replaced by another with the same specifications.

In July, Uniformity Tests were conducted on July 10, 13 and 25.

In August, ADRITIC switched the pump temporarily due to performance issues – it was not operating sufficiently and could not produce the pressure required. The following week (August 7), the ADRITIC team went with MIRRA to reinstall the pump and replace the substitute pump. It was at this time that the teams noticed that the valves had been tampered with near sites 13 and 14; the electric wires had been cut. This was later repaired. The pressure at the filters and valves checked out during the visit on August 8. The data loggers were fixed at sites 11 and 12; however, the flow sensors were not working because the algae had accumulated at the bottom of the device around the coil. After it had been removed and cleaned, it still did not produce a reading. Also, pressure sensors numbers 2 and 3 from data logger 11 had to be separated. ADRITIC installed the valves at the end of the submain, after which there was no change in pressure (bar 1) at sites 11 and 12 and remained at 0.4. The problem had not been solved. Water samples were taken from the pond and from the emitters to be examined (see Appendix page 15 or full list of water testing results and dates). At sites 11 and 12, the minimum pressure was met; however, testing at sites 13 and 14 was not possible due to the low pressure. In order to solve the pressure problem, ADRITIC decided to change the submain at the pump, from 1.5 inches to 2 inches with a length of 100 meters (August 22). Even after this change, the pressure was not optimal.

Concluding the activities at Sharhabeel for the project year, MIRRA team changed the clogged emitters at sites 11 and 12 and replaced the 2.5 HP/1 FAZ pump with a new 3 HP/ 3 FAZ pump (September 6 and 11, respectively. The pomegranates at sites 13 and 14 have been devastated by the insect infestation that was observed and reported to NCARE previously. The loss of these crops is due to the failure to periodically apply pesticides to ward off the insects on the part of NCARE. On September 12, MIRRA and ADRIEC calibrated the pressure with the new pump as well as the minimum pressure output. This was followed up with a Uniformity Test the next day.

At the end of the month, MIRRA and MIT teams went to sites 11 and 12 to clean flow sensors 1 and 2 of algae using a carburetor cleaner, fix pressure sensors 4 and 5 by fixing the electrical

7

wire, and calibrated flow sensors 1 and 2. Flow sensors 3 and 4 were cleaned and calibrated at sites 13 and 14.

The start of the new project year (October) began with MIRRA observing algae in the irrigation lines. The team injected phosphoric acid (at 2 percent) into the system, starting from the fertilizer applicator after the system was flushed. Minimum pressure results were recorded at each site at Sharhabeel, and on October 9 a Uniformity test was conducted at sites 13 and 14.

Results of the minimum pressure test for the MIT Plots, conducted on October 5, was measured at 0.25 bars in the Citrus plot & 0.55 bar in Pomegranate plot. Furthermore, the results of the minimum pressure test for the TRD Plots, conducted on October 5, was measured at 1.2 bars in the Citrus plot & 1.2 bar in Pomegranate plot. On October 14, the team injected phosphoric acid and flushed the irrigation system to avoid algae buildup. There was a concern that DAQ 12 was not saving data due to the instrument’s memory card; however, MIT reported that they are still receiving up-to-date data. The next day, the irrigation system was flushed and new results for a Uniformity Test at sites 13 and 14 were taken. MIRRA agreed with NCARE to reduce irrigation time at the sites. Concluding activities in October were new Uniformity Tests (October 19, 29 and 31).and Met with the station manager to discuss and agree on Field Day arrangements. MIRRA continued Uniformity Tests on November 2.

The following week was the first Field Day at Sharhabeel. Farmers who attended the Field Day were informed of the project work through discussions about low-energy drip irrigation, an elaboration of the advantages the emitters can provide farmers, as well as a tour of the station to see the system first hand. MIRRA assured farmers, who agreed to be participants of the program that the team would give their full support in installing and following up with the emitter’s application on their farms.

RAMTHA STATION (Site 15)

Al-Ramtha Station is the second farm of the National Center for Agricultural Research and Extension (NCARE) selected for project work. Its located 7 km north of Ramtha and covers 16 dunums, of which 1 dunum of unplanted field is being used by MIRRA. The fields are fed with treated wastewater from the Ramtha purification station in open quantities during working hours, as per agreement between NCARE and the Water Authority of Jordan (WAJ).

MIRRA started at Al-Ramtha Station at the start of May. At that time, ADRITIC had installed a drip irrigation system. The experimental area was divided into four plots, each plot divided into two sections, where traditional ADRITIC and MIT low-pressure emitters were installed. Both types of emitters were set to operate at three different pressures – (1, 0.5, and 0.25) bar.

Water storage became an issue at the site and MIRRA installed water tanks with a total volume of 8m3. However, it was not enough to conduct a uniformity test. So, MIRRA then replaced the water tanks with a pond on June 13, sealed with 400 microns of new mulch to solve the problem. Later, the 1.5 hp pump was replaced with a 3 hp to improve efficiency and conduct a Uniformity Test.

All in all, an electric pump 3 HP, a pump kit, a disk filter, sand filter,(3) pressure relief valve (PRV), (10) manometers, (3) flow meters, (3)pressure sensors, (3) flow sensors, and (1) data loggers were installed.

When MIRRA went out to the field to conduct Uniformity Tests on July 2, the team noticed an abundance of grass in the sections with MIT’s emitters. The station’s workers clean the experiment filters every irrigation day. A week later (on July 9), MIRRA replaced the manometer for accuracy issues.

The four tanks that were later replaced by a pond.

Crops: none Water Source: treated wastewater from the Ramtha purification station. Irrigation: online irrigation (PC) Devices Installed: an electric pump 3 HP, a pump kit, a disk filter, sand filter, (3) pressure relief valve (PRV)), (10) manometers, (3) flow meters, (3) pressure sensors, (3) flow sensors, and (1) data loggers were nsta.

The MIRRA team conducted Uniformity Tests on July 19 plot by plot to ensure accuracy. During testing, it was observed that when the water level in the pool drops (a half meter), the pressure in the system is also reduced.

At Block 2, there was a challenge to get the appropriate pressure. To remedy the issue, one of the valves was switched off until the Uniformity Tests could be completed. On July 26, a group of students from the Jordan University of Science and Technology’s (JUST) Faculty of Agriculture accompanied by Dr. Naji Mufleh visited the project site at this station. The MIRRA team was at the site and explained the project to the students. Uniformity Tests were conducted at Block 4 on August 1. The following week, (August 9) the team went to Ramtha station to calibrate the flow sensors and found that the pressure was low. The filter was cleaned as a result and the problem was fixed. The team’s aim was also to clean the submain lines and had installed valves at the end of each line, three valves one for each line. The team then took a sample of water from the pond for NCARE to examine. August 14, the team disassembled the laterals on which the local emitters had been fixed, and at the request of the MIT team, their place was closed. MIRRA headed to Ramtha Station to remove the pipes with local emitters on September 5. At that time, a Tunisian delegation was received at the station whose aim was to study wastewater and its uses in agriculture. The team used the opportunity to explain the project, the emitters and their efficiency.

11

MIRRA installed new laterals with MIT emitters, replacing the laterals with the local emitters (September 18). The following week, MIRRA and MIT teams replaced the flow sensor, cleaned flow sensors 1 and 2, and calibrated flow sensors 1, 2 and 3. In October, it was noted that the rubber in the sand filer was leaking. It was later replaced. The large number of weeds and soil moisture, due to the inability of the soil to absorb irrigation water, made it difficult for the MIRRA team to conduct work. The irrigation schedule was altered from three days a week (half an hour on Sunday, half an hour on Tuesday and three hours on Thursday during the Uniformity Test) to once a week (3 hours). Uniformity Tests were conducted October 8 (filters were cleaned), 15 (no issues observed), 22 and 29.

MAFRAQ STATION (Site 16)

The 5-dunnum site of the olive orchard at site 16 was chosen to be included in the study. This site is divided further into two parts: Plot 1 – with 12 rows, 96 trees, 12 laterals and affixed with MIT’s low-pressure emitters; Plot 2 – 103 trees, 12 laterals and affixed with ADRITIC emitters.

The electric panel is located far from the location of the experiment. To extend the access to electrical power, the team installed solar panels in order to sufficiently operate the equipment, excluding the pump. The Uniformity Test on May 29 was conducted without any problems. However, there were a lot of weeds at the site. The team discussed this with the farm workers. The following month the team went to supervise the installation of mulch around certain trees.

Crops: 80 percent of the farm is planted with Olives and the other 20 percent is covered with apricots, peaches, grapes, persimmon and cacti. Black mulch covers around the tree to prevent the growth of weeds and evaporation. Water Source: Groundwater is utilized and drawn using an electric 50-hp, 37 Kw pump. Irrigation: Uses PC emitters covered with black plastic mulch to prevent evaporation. Devices Installed: (for plots 1 & 2) (2) flow meters, (2) manometers, (2) flow sensors, (2) pressure sensors, a data logger and a solar panel.

The Uniformity Tests on June 21, July 19 and July 31 were successful without any problems to report. However, during the tests, the MIRRA team noticed that there were trees infected with Verticillum fungi, which causes the tree’s branches to dry out. The owner of the farm was notified and farm workers began removing some injured branches from the site. There weren’t many activities at Mafraq in August. Monitoring the irrigation and recording the pressure readings was ongoing.

On August 15, pressure measurements checked out, the solar panel was cleaned and information from the data logger was downloaded. Results of the minimum pressure test on August 29 were measured at 0.35 bars.

The team noticed that the trees are increasingly infected with the fungus and that no attempt to control its spread or treatment has been attempted.

MIRRA visited the Mafraq Farm on September 7 to take samples of the tree branches. Because there is an infection among the olive crops, MIRRA worked to ascertain the cause of infection and confirm that it is not due to project operations at the farm. During this work, the team noticed that some of the rubber on the emitters had been removed and/or were missing.

Later in September, an iron plate was installed to display the logos of the project’s participants. On September 24, the team returned to take additional samples from the crops branches, the soil and water to examine them. MIT adjusted the pressure at the traditional site so that the pressure recorded at the farthest tree would be 1 bar. They then adjusted the flow sensor’s calibration. Also, Julia provided assistance about using the DAQ. Uniformity Tests were conducted on September 11. MIRRA met with the owner of the farm to arrange for the crops to be irrigated once a week without altering the pressure (October). This was to ensure that MIRRA would be able to conduct Uniformity Tests regularly once a week. MIRRA noted that the flowmeter at the plot was not working, possibly due to a defect. ADRITIC was notified. Also, the memory card in DAQ 15 was defective and was not storing information at which time Julia was notified. The results of the minimum pressure test for the TRD plot, conducted on October 7, were measured at 1.4 bars.

Later, the action of the flowmeter had completely stopped. The ADRITIC team removed the flowmeter and found that there were rubber lashes, of which the source was unknown. These were removed and a new flowmeter was installed. Uniformity Tests were conducted October 7, 12, 21, 24, 28 and 31.

MIRRA-MIT END-OF-First Year MEETING MIT’s Visit to Jordan (September 2017)

To wrap up the first year of the partnership, MIRRA welcomed the MIT team to Jordan and made a complete round of site visits following the team’s arrival on September 25.

The first site visit was to Ramtha, where the teams changed the second flow sensor, cleaned flow sensors numbers 1 and 3 and calibrated sensors 1-3.

On Wednesday, the teams ventured to Sharhabeel and observed operations at the citrus (sites 11 and 12) and pomegranate orchards (sites 13 and 14). At the citrus site, teams cleaned flow sensors 1 and 2 of algae, fixed the pressures sensor at the MIT site by replacing electrical wires 1 and 2 and recalibrated them. Flow sensors at sites 13 and 14 were also cleaned and calibrated. The following day, the team met with Naeem Mazahreh. NCARE measured the Emission

Uniformity at Sharhabeel. The results are as follows:

Pressure at end of MIT lateral was set to 0.15 bar

○ Used 8 emitters at each of the start, middle, and end of lateral

○ Result: DU of ~72% for MIT and ~89% ADRITIC traditional drippers.

The results of the field tests were consistent with previous CV measurements taken lab. MIT plans to conduct a sensitivity analysis to test whether manufacturing tolerances are the source of the higher CV. An Update Meeting was held between MIRRA and MIT on September 30. The following was established:

Phase I

All issues regarding the flow and pressure sensors have been resolved and that a new procedure is in place to regularly clean and calibrate flow sensors.

Including farm sites that make use of different water sources has been valuable. The teams were pleased to see that there has been no clogging at the Ramtha site, which uses treated wastewater in its irrigation system.

For Phase 1B, the teams will focus on about 3-5 farmers, with 2-4 laterals only, with existing drip irrigation systems.

Concerning in-line trials, a low flow rate for solar installations and a higher flow rate may be needed for grid installations.

Amos and Susan check the manometers, pressure and filters. Julia and Elizabeth examine the flow sensors at Ramtha.

16

Formbook 1 is to be slightly modified to measure the pressure at the end of the lateral using the handheld manometer in addition to emitter output. New workbooks and detailed instructions are to be shared with MIRRA.

The Annual Plan was revised and the latest version was sent to all partners.

Phase II

The teams are considering replacing the MIT drippers at Sharhabeel prior to starting Phase II because they may be clogged with algae.

The teams would like to include at least one greenhouse.

MIT urgently needs information about the rated flow rate and duration of irrigation for potential Phase II sites; MIRRA is working on it.

On September 30, the teams met with Dr. Fayez Khasawneh at which time he expressed his desired outcomes of the collaboration as well as his intentions for his farm:

Irrigation:

Overall, he wants a reliable dripper.

He uses ADRITIC GR drippers because they use newly manufactured material; recycled materials have a shorter life span.

His GR drippers are 30 cm apart, 4L/hour, and laterals per plant. GR is used on his apricots, peaches, persimmons and grapes.

Future of the farm:

He is leaving olives because they are high-risk regarding the climatic conditions as well as the seasonal hot, dry desert wind that carries the potential to ruin his entire crop. Additionally, labor is too expensive: shaking the trees to gather the fruits damages the root system whereas hiring pickers is not financially feasible. Also, government import and export policy is also high risk as Dr. Khasawneh could lose his market or market prices fall to a level that he cannot export his crop.

By the end of November, he plans to have cut down most of his olive trees and plant stone fruit by February 1.

Labor costs are a burden for the entire agricultural sector. The particular case with olives is harvesting the fruit in an economical way for farmers without damaging the trees or future crops at the same time.

On the first of October, the teams were at NCARE headquarters where they were acquainted with the organization’s activities. NCARE has previously worked with the National Science Foundation, USAID and USDA. They said that they would be eager to work with MIT to take on a larger role and, potentially, scale up after this USAID grant. Concluding the week was a site visit to Mafraq, where the teams recorded a pressure of TRD 1 bar at the furthest tree at the site. Flow sensors 1 and 2 were also calibrated. MIT departed from Amman October 1.

CONCLUSIONS AND FEEDBACKS

During the first year of the project, MIRRA met with many farmers and had close views on agriculture,

its costs and difficulties. Interesting farmer opinions and feedbacks expressed during the first year are

summarized as follows:

In Mafraq, farmers' opinions were about the problem of pumping costs from wells. Most preferred to

use the GR system and the so called K- clip, which gives irrigation water up to 20 liters per hour. The

majority agreed that the PC points are very problematic in terms of slowness, disorientation, failure to

give fixed flow rates of the beginning of the line to an end, and farmers complaining about the problem

of miss-manufacturing points.

The Jordan Valley also suffers from problems at least from the difference in terms of the availability of

water. There is suffering in providing it, so that farmers depend on the water of the Jordan Valley

Authority, which arrives once or twice a week and possibly in other areas three or four days a week but

for a few hours, forcing them to rely more on the open irrigation systems without the use of emitters, in

order to gain time and greater quantity of water.

The farmers also consider the filters to be expensive. They were concerned about the repeated cleaning

of the filters and that if they were not cleaned continuously they would affect water pressure.

Everyone welcomes the installation of modern irrigation systems but they are looking for lower costs.

Solar energy is also a welcomed idea, but everyone also needs financial support to install it for their high

costs. They are also hesitant about whether the solar energy system can operate a pump of more than 3

hp.

Following is a list of issues that MIRRA had to deal with during the first year:

Mafraq:

1. Like many farms in Jordan, this farm is run by foreign workers. In this case, it is a family from

Pakistan that have been living in Jordan and working in Agriculture since the late 1970’s. They are

considered to be loyal workers but their level of education and knowledge of irrigation principles or

engineering is very limited. Hence, we ran into a number of technical issues with them. On the other

hand, the owner of the farm is a highly educated Jordanian with great knowledge in irrigation

principles. However, he only visits the farm 1-2 time a month.

2. The workers in Mafraq farm used to change the valve settings on the MIT plot on irrigation events

when MIRRA staffs were not there. He thought this will increase the amount of water reaching the

plants. He was also afraid of the explosion of the main lines because of reducing the pressure at the

MIT plot. It took several attempts to convince the farmer with our methodology.

3. The workers of the Mafraq farm at a certain time removed the rubber inside the emitters to increase

the amount of irrigation water. After some explanations, we convinced them not to do that.

4. Because of the frequent shutdown of the pump (it shuts down for 15 minutes every hour), there was

not enough time sometimes to conduct uniformity tests properly and it was challenging to conduct

minimum pressure tests.

5. Very little attention is given to weed control in this farm. This made our work challenging and

unsafe at times especially when investigating clogging and conducting uniformity tests. We had to

hire workers to remove the weeds from our plots.

18

6. Power outages were common especially during the summer months. This led to delays in work and

sometimes failure to complete a uniformity test.

7. Due to the large farm size, the pump used on the farm is a large one resulting in a high pressure

value. It was challenging to adjust the valves to reduce the pressure to our desired level.

Ramtha:

1. This NCARE research site was poorly maintained with almost no infrastructure that we could use

(so we had to build the system from scratch) and workers on this site were poorly trained on

management of irrigation systems.

2. Due to the absence of crops to absorb the irrigation system waters and the clay-nature of the soil,

the site used to get muddy especially during the fall. This resulted in conditions that are challenging

to conduct a uniformity test or monitor clogging. We had to adjust the irrigation schedule to

mitigate this condition.

3. Weeds grew at a high rate due to the nature of the water (treated wastewater) used which was rich

in nutrients. The research station workers were not able to control the weeks and complained often

from our requests to keep the site clean. This resulted in condition un-safe for our staff to work. We

had to pay extra service fees to keep the site clean.

4. Water storage capacity at this site was a problem at the start of the work, but eventually we

invested in a large irrigation tank (~200 m3) and that solved this problem.

5. Workers at this site were not trained properly to operate sophisticated irrigation systems. They

were unable to read the pressure meters correctly, which required us to train them.

6. It took several attempts for the irrigation supplier to provide the adequate sand grain size

appropriate for this type of water used at the site.

Sharhabeel:

1. This is also an NCARE research site. Again, here, we had to build the irrigation system from

scratch. There was no functioning infrastructure that we could use like we did in the private farm at

Mafraq.

2. The water quality at this site was challenging to work with because of the presence of fish in the

irrigation pond. This resulted in the buildup of algae in the irrigation system and clogging of the

flowmeters and emitters. To resolve this we started acid injections in the system. This turned into a

frequent practice.

3. Workers on the site had very short working hours, from 7:00 am to 1:00 pm. It was difficult to work

around that. Hence, we had to buy additional working hours in order to be able to collect the needed

data during irrigation events after 1:00 pm.

4. Workers also were not able to read – they were unschooled. We could not rely on them in taking

readings of the pressure gages or flow meters. To resolve this, we had to rely on them taking

pictures during irrigation events when we were not on site. In addition, we encountered a problem

training them to reduce the pressure to 0.25 bar at times when we were not present at the site.

5. The site was not maintained properly as desired for favorable working conditions. Weed growth

was a common problem; we had to request weed removal several times. Pesticides were not used

measure the yield properly.
