Question

what is the technique of planting different crops in the same field in alternating seasons to improve soil health? contour plowing monocropping no - till farming crop rotation

Explanation:

Crop rotation involves planting different crops in the same field in alternating seasons. This helps improve soil health as different crops have varying nutrient - requirements. For example, legumes can add nitrogen to the soil, which benefits subsequent non - legume crops. Contour plowing is for soil erosion control along slopes, monocropping is growing the same crop continuously, and no - till farming reduces soil disturbance but is not about alternating crops for soil health in the way crop rotation is.
