Soil capacity refers to the ability of soil to hold and retain water, nutrients, and air. It is an important factor in determining the fertility and productivity of soil for plant growth. Soil capacity is influenced by factors such as soil texture, structure, organic matter content, and compaction. A soil with high capacity can provide adequate water and nutrients to plants, while a soil with low capacity may require additional inputs to support plant growth.

Soil capacity refers to the ability of a soil to hold or store certain substances or elements. There are several types of soil capacities:

- Water holding capacity: This is the amount of water that a soil can hold against gravity. It is determined by the soil's texture, structure, and organic matter content.
- Nutrient holding capacity: This is the ability of a soil to retain and release nutrients for plant growth. It is influenced by soil pH, organic matter content, and clay content.
- Cation exchange capacity (CEC): This is the capacity of a soil to hold positively charged ions (cations), such as calcium, magnesium, and potassium. CEC is determined by the type and amount of clay minerals and organic matter in the soil.
- Buffering capacity: This is the ability of a soil to resist changes in pH. It is influenced by the amount and type of clay minerals and organic matter in the soil.
- Organic matter capacity: This is the ability of a soil to hold and store organic matter. It is influenced by soil texture, structure, and microbial activity.

Soil capacity is an important factor in soil fertility and plant growth. Soils with high water holding capacity can support plant growth during droughts, while soils with high nutrient holding capacity can provide plants with the nutrients they need for growth. Soils with high CEC can help to reduce nutrient leaching and maintain soil fertility. Soils with high buffering capacity can resist changes in pH that can affect plant growth. Soils with high organic matter capacity can help to improve soil structure, fertility, and water holding capacity.
