EXPLAIN CONSERVATION TILLAGE IN DETAIL.
Answers
Conservation tillage is any method of soil cultivation that leaves the previous year's crop left over on fields before and after planting the next crop, to reduce soil erosion and runoff of water. Conservation tillage is especially suitable for erosion - prone cropland.
Answer:
Explanation:
Conventional tillage is the traditional method of farming in which soil is prepared for planting by completely inverting it with a tractor-pulled plough, followed by subsequent additional tillage to smooth the soil surface for crop cultivation. In contrast, conservation tillage is a tillage system that conserves soil, water and energy resources through the reduction of tillage intensity and retention of crop residue. Conservation tillage involves the planting, growing and harvesting of crops with limited disturbance to the soil surface.
Tillage of the soil stimulates microbial decomposition of soil organic matter, which results in emissions of CO2 to the atmosphere. Therefore, minimising the amount of tillage promotes sequestration of carbon in the soil. In the last decades advancements in weed control methods and farm machinery now allow many crops to be grown with minimum tillage
