INTRODUCTION

• Agriculture

• Soil requirements

• Minerals

• (N, P, K)

• Organic matter (Humus)

FARMING TYPES

• Mainly two types of Farming :

Chemical Farming

Organic Farming

CHEMICAL FARMING

• Lays emphasis on use of Chemicals

Advantages

Nutrient specific

Rapid results

High yields

Disadvantages

Pollution

Soil quality

Eutrophication

Ground water pollution

Biomagnification

ORGANIC FARMING

A production system which avoids the use of synthetic fertilizers

Integrated Pest

METHODS OF ORGANIC FARMING

Organic Pest Control Soil Quality Biodynamics Vermiculture Earthworm : The Natural Bioreactor Vermicompost

ORGANIC FARMING

ADVANTAGES

Natural Resources remain intact

Pollution hazards

Use of Organic Wastes

Employment opportunities

Generate Original Eco system

Lower Investments

DISADVANTAGES

Not Nutrient Specific

Labour

Timely vigil

• CASE 1:• Name of plant : Tulsi• Scientific name : Oscimum sanctum• Height : 1-1.5ft.• Plant type : Herb• Leaf type : Variegated, reticulate venation, Dicot ANALYSIS: A frail tulsi plant was taken as a sample study. It was observed for a

period of 24 days. It was supplied with an Organic preparation in addition to wastes supplied to it.

OBSERVATIONS: The plant was observed to recover within the stipulated time. CONTROL: A plant treated with chemicals INFERENCE: Organic inputs were found to be more effective. The soil treated with

Organic preparation was found to be of pH 6.1 while the one with chemicals was tested for 4.5

CASE STUDY

• CASE 2:• Name of plant : Toor• Scientific name : Caganus cagan• Height : 3 ft.• Plant type : Annual• Leaf type : An oval leaf blade, reticulate,

Dicot, Legume ANALYSIS: A toor plant was taken as a sample study. It was observed for a period of 6

months. The plant was supplied with an Organic preparation in addition to Organic wastes supplied to it.

OBSERVATIONS: The plant was a success as a perennial crop by supplying three yields.

The grains were found to be sweet , large in size. It also recorded an extra growth of 5ft.

CONTROL: A plant supplied with chemicals. INFERENCE: Organic inputs were found to be more productive and economical. The soil

with Organic inputs recorded pH 6.0 whereas that treated with chemicals recorded a pH of 5.2

CASE STUDY

COMPARATIVE STUDY

• Chemical Farming

ة Use of chemicalsة Eco unfriendlyة Nutrient specific but

hazardousة The farmer spraying the

chemicals is affected.ة Uneconomicalة Not sustainable

• Organic Farming

ة Discard of chemicalsة Eco friendlyة Nutrient specific, non

hazardousة Does not involve chemicals

so no side effects.ة Economicalة Sustainable

COMPARATIVE STUDY

• Organic Farming Higher Nitrogen fixation High microbe activity Less loss of nutrition SUSTAINABLE

• Chemical Farming Nitrogen reduced Reduced microbes High Nutrition loss UNSUSTAINABLE

.Chemicals are eco unfriendly while organic wastes are easily decomposedة

CONCLUSION

• Organic Farming is Nature friendly.• It is soil sustaining.• THUS ORGANIC FARMING CAN BE CONSIDERED THE MOST SUSTAINABLE FORM OF AGRICULTURE.
