World nurture Conservation day July 28
Conservation is the utilization without wastage of resources is required to ensure a high level of pro-duction.
Important soil conservation measures are
•Zero tillage•Stubble mulching
•Farming across the slope
•Mixed cropping and intercropping
•Timely farm operations
•Improved water user efficiency
•Providing safe drainage
•Growing vegetation on the bunds
Vegetation and vegetative management
•Mulching Wind erosion management
•Protect the soil surface with a cover of vegetation or vegetative residues.
•Produce or bring to the surface soil aggregates or clods which are large enough to resist the wind force.
•Roughen the land surface to reduce wind velocity and trap drifting soil.
•Establish barriers or trap strips at intervals to reduce wind velocity and soil drifting.
Best practices to control soil blowing
•Wind breaks and shelterbelts
•Mechanical or vegetative barriers For instance:
Shelterbelts for moderating microclimate
•Shelterbelts reduce wind velocity
•Reduce evaporative loss and conserve soil moisture
Water erosion can be managed by
•In situ water harvesting
Overland flow management
•Broad based bund
•Water harvesting and recycling
•Several practices are in use such as zero tillage, minimum tillage and direct seeding.
•Planting crops in previously untilled soil by opening a narrow slot, trench or band only of sufficient width and depth to obtain seed coverage. No other soil tillage is done.
Advantages of zero tillage farming
•Erosion control: Retained stubble and crop residue reduces soil erosion and enhances soil fertility
•Moisture conservation: Stubble traps water, reduce runoff water, better infiltration leading to improved soil moisture condition
•Higher nitrogen availability
•Seedling protection: Stubbles protects young seedling from wind and heat
•Crop yields will be on par with traditional tillage system. However good yield can be harvested during dry years
•Reduce labour and save time
•Savings on equipment cost
•Savings on oil/fuel cost
