Description of practice
Adding sand is the practice of spreading sand or sandy soil on agricultural soil to improve drainage, increase infiltration and reduce evaporation. It may also help to increase soil depth and add nutrients to degraded soil.
|Examples of how to use adding sand
(see Note below)
Adding white sand
White sand is added to soil to improve infiltration and reduced cracking of topsoil, leading to increased moisture in subsoil. White soil also reduces evaporation (less absorption of sunlight) and repels insects.
Adding red soil
Adding red (fertile, nutrient rich) valley soil to degraded soil on slopes increases the soil depth and adds nutrients. It combats erosion and nutrient depletion.
Creating a sand substrate
Sand is brought from a nearby source to create a new substrate for tree crops that require permeable, light-textured soils with a low clay content.
