Some facts: • Essential nutrients in plants although the content in the plant
is in a modest concentration (2 g P per kilo of dry matter).
• Irreplaceable / have no substitutes
• The lithosphere has a low nutrient content (i.e. P: granite has 0.6 g kg–1; slate: 0.8 g kg–1; basalt: 1.5 g kg–1)
• They are not available for the plants in many cases (i.e. P: almost all of it in the same package: apatite)
Minimum P needs:
0,6-0,7 g P per person and day

ATMOSPHERIC DEPOSITION
P concentration (as PO43-) in the soil solution is
below 10-6 M in many virgin or non-fertilized soils, and between 10-6 to 10-4 M in many fertilized soils. …. that means it lasts less than a sweet at the gates of a school

Therefore, it is necessary to keep an adequate P level in the soil solution

Which is the role of fertilizers? to increase the concentration of soluble nutrient forms in the soil solution, in such a way that they will be more easily available for the roots

Which trends in the fertilizers world are related to fertilizers and farm intensification?
Fertilizers
To improve the analytical methods and the strengthening of the interpretation in order to improve the diagnosis and fertilizer recommendation To improve the management of fertilizers and crops Design of new fertilizer products that enhance nutrient use efficiency To find new Nutrient sources in Europe, with high quality and high nutrient available content

- Nutrient recovery from biobased Waste for Fertiliser production
Nutrient recovery
This project has received funding from the Bio Based Industries Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 668128
The objective
NEWFERT project tackles the design and development of different
enabling technologies to allow the re-use and valorisation from
biowaste making them suitable as secondary raw material in the
fertilizer industry: a new brand of cost-effective, eco-friendly and
healthy advanced fertilisers. Furthermore, NEWFERT targets highly
plant available combination of specific organic and mineral components
and sets up ranges of their concentration in NPK fertilisers.
The objective
Close the loop ensuring high nutrient concentration safety stability availability economic viability
Partners
2015-2018
Methodology The project starts working with data collection, characterisation and analysis of biobased residues. Two main waste ways for nutrients recovery: 1. Design new process to recover nutrients from solid biowaste (sewage,
manure and household waste, etc.) modifying existing industrial processes, development of new chemical nutrients extraction technologies and scale-up of the integrated system.
2. Involving different technologies of nutrients recovery from liquid biowaste. • Chemical acidification, separation, struvite crystallisation and
nitrogen recovery as ammonium sulphate. • Bioelectrochemical system. This technology based on Microbial
Electrolysis Cells.
The fertilisers obtained with these biowastes will be validated in an agronomic demonstrative environment.
