Study Notes
Plant Selection and Cultivation
- Selective breeding is used by farmers to selectively cultivate only healthy plants.
- Continuing to grow the same crop year after year in the same field leads to soil depletion and reduced fertility.
Crop Rotation and Fallowing
- Leaving agricultural land uncultivated for one or more seasons, a practice called fallowing, allows the soil to replenish its nutrients.
Nitrogen-Intensive Crops
- Leguminous crops, such as beans, lentils, and peas, use lots of nitrogen.
Paddy Field Management
- Transplantation in paddy fields ensures uniform growth and better crop management.
