Phytoremediation is the use of specific plants to remove, transfer, stabilize, and destroy contaminants in soil, thus improving its quality and making previously unusable land suitable for agriculture.

Soil amendment entails the addition of materials to soil, such as compost, manure, or lime, to improve its physical properties, nutrient levels, and overall fertility for better crop growth.

Afforestation involves planting trees on non-forest land to create a new forest. It improves land quality by preventing erosion, enhancing soil moisture retention, and increasing biodiversity.

Salinity Control uses various techniques to reduce salt levels in soil, such as avoiding high-salinity water sources, improving drainage, and applying gypsum. This enhances crop yield and land sustainability.

Controlled drainage is the water management technique of manipulating water table levels to optimize soil moisture for agriculture while minimizing waterlogging and leaching of nutrients.
