Crop Rotation

Subject – Agriculture

Context – Implement crop rotation. This can to a large extent ease Punjab’s agrarian crisis.

Concept –

Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons.
It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pest and weeds.
Conversely, a well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops.
Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience.

Monocropping

Growing the same crop in the same place for many years in a row, known as monocropping.
It gradually depletes the soil of certain nutrients and selects for a highly competitive pest and weed community.
Without balancing nutrient use and diversifying pest and weed communities, the productivity of monocultures is highly dependent on external inputs.
