Capping in relation to soil refers to the formation of a hard, impermeable layer on the surface of the soil. This layer can be caused by factors such as compaction, erosion, or the accumulation of salts or minerals. Capping can prevent water from infiltrating the soil, leading to poor drainage and reduced plant growth. It can also increase runoff and erosion, as water is unable to penetrate the soil surface. Capping can be detrimental to soil health and productivity, and may require remediation measures such as tilling, aeration, or the addition of organic matter to break up the impermeable layer.

Capping (Soil Science)
Capping is a soil degradation process that involves the formation of a hard, crust-like layer on the surface of the soil. It is caused by the accumulation of fine particles, such as clay, silt, or organic matter, on the soil surface.
Causes of Capping:
- Excessive rainfall or irrigation
- Poor drainage
- Soil erosion
- Detachment and transport of fine particles by wind or water
- Compaction of the soil surface
Effects of Capping:
- Reduced water infiltration: The crusty layer prevents water from entering the soil, leading to poor drainage and waterlogging.
- Poor root penetration: The hard layer restricts root growth, affecting nutrient uptake and plant growth.
- Increased erosion: The capped surface is more susceptible to erosion, as fine particles can be easily detached by wind or water.
- Reduced soil biodiversity: The anaerobic conditions created by waterlogging inhibit the growth of beneficial soil organisms.
Prevention and Mitigation of Capping:
- Adequate drainage: Ensure proper drainage to prevent waterlogging and erosion.
- Soil amendments: Incorporate organic matter, such as compost or manure, into the soil to improve structure and reduce compaction.
- Mulching: Cover the soil surface with organic materials to protect it from erosion and promote water infiltration.
- Conservation tillage: Minimize tillage operations to preserve soil structure and reduce erosion.
- Adequate vegetation cover: Establish vegetation on the soil surface to hold the soil in place and improve drainage.
