The correct answer is: A) Adding organic matter.
Laterite soils are highly weathered and acidic, and they are low in nutrients and organic matter. Adding organic matter to laterite soils can help to improve their fertility and productivity. Organic matter can help to improve the soil’s structure, water retention, and nutrient-holding capacity. It can also help to reduce soil erosion and improve the soil’s ability to resist pests and diseases.
Chemical fertilizers can also be used to improve the productivity of laterite soils. However, chemical fertilizers can be expensive and can pollute the environment. They can also leach out of the soil and become unavailable to plants.
Increasing irrigation can also help to improve the productivity of laterite soils. However, irrigation can be expensive and can lead to waterlogging and salinization of the soil.
Monocropping, or the practice of growing a single crop on a piece of land year after year, can lead to soil degradation and a decline in crop yields. Monocropping can also increase the risk of pests and diseases.
Therefore, the best way to make Telangana’s laterite soils more productive is to add organic matter.
