INTRODUCTION

• Agriculture
• Soil requirements
• Minerals
• (N, P, K)
• Organic matter (Humus)

4
FARMING TYPES

• Mainly two types of Farming
• Chemical Farming
• Organic Farming

5
CHEMICAL FARMING

• Lays emphasis on use of Chemicals

Disadvantages
Advantages
Nutrient specific Rapid results High yields
Pollution Soil quality Eutrophication Ground
water pollution Biomagnification
6
ORGANIC FARMING
A production system which avoids the use of
synthetic fertilizers
COMPONENTS OF ORGANIC FARMING
7
PRINCIPLES OF ORGANIC FARMING

• Biodiversity
• Sustainability
• Natural Plant Nutrition
• Natural Pest Management
• Integrity

8
METHODS OF ORGANIC FARMING

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

ORGANIC FARMING
ADVANTAGES
DISADVANTAGES

• Natural Resources remain intact
• Pollution hazards
• Use of Organic Wastes
• Employment opportunities
• Generate Original Eco system
• Lower Investments

• Not Nutrient Specific
• Labour
• Timely vigil

CASE STUDY

• 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

COMPARATIVE STUDY

• Chemical Farming
• Use of chemicals
• Eco unfriendly
• Nutrient specific but hazardous
• The farmer spraying the chemicals is affected.
• Uneconomical
• Not sustainable

• Organic Farming
• Discard of chemicals
• Eco friendly
• Nutrient specific, non hazardous
• Does not involve chemicals so no side effects.
• Economical
• Sustainable

13
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 decomposed.

STATISTICAL DATA

• COUNTRY
• Sweden
• Australia
• USA
• Uruguay
• Germany
• Italy

• OF LAND UNDER ORGANIC CULTIVATION

15
CONCLUSION

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