SOIL BUILDING MANAGEMENT
The soil is a living medium, which is provides base to the trees and plants, and nutrients. It should have Macro organisms like earthworms etc. and beneficial microorganisms in sufficient numbers. In general, Soil contains at 25 percent air, 25 percent water, 45 percent mineral matter and 5 percent organic matter. Well structured soils are crumbly and fragile. The pH value should be between 6.5 to 7.5, Soil should be good in drainage for better production.
At present there are many challenges of Indian soils:
- Over use of chemicals and other activities destroying soil micro flora and fauna
- Every year thousand tons of top soil loss. ( Soil Erosion )
- Rise in soil pH, Low Organic carbon and unavailability of nutrients
- Crop residue burning on land leads to burning of organic carbon and Soil organisms death
- More occurrence of disease organism in chemical soils
- Occurrence of heavy metals in soil
Objective of Soil Building program
- Improvement in soil structure
- Increase in soil porosity
- Increase number of soil Flora and Fauna
- Improve soil texture
What we do?
- Soil testing
- Drainage improvement
- Use of light weight implements to avoid compaction of soil
- Adoption of Crop rotation , mix and multi cropping
- Soil engineering i.e Farm contour bunding, Land Levelling operations
- Promotion of zero or minimum tillage operations
- Ban on crop residue burning
- Controlled irrigation
- Balance use of FYM / compost, green manure to improve organic carbon content etc.
- Training and Practical Demonstration of technologies at farm level
- Making Village Subject matter specialist / master trainer / resource person ( Bhu Rakshak )
- Linking farmers with Government department schemes.
