Explanation:
1. Crop diversification refers to the practice of growing a variety of crops in a particular area over time. This helps in reducing the risk of crop failure, improving soil health, and promoting biodiversity.
2. Legume intensification involves increasing the cultivation and use of leguminous crops. Legumes have the ability to fix nitrogen from the atmosphere, which reduces the dependence on synthetic fertilizers. They also improve soil fertility and provide nutritious food.
3. Tensiometers are instruments used to measure soil moisture tension. By using tensiometers, farmers can monitor soil moisture levels and apply irrigation water only when necessary, reducing water wastage and improving water use efficiency.
4. Vertical farming is a method of cultivating plants in vertically stacked layers or structures, often in urban areas. It maximizes land use efficiency and reduces the need for large land areas for agriculture. It also reduces water usage and pesticide application.
