After the drainage has stopped, the large soil pores are filled with both air and water while the smaller pores are still full of water. Add the water and Coir and lime together in large cooking pot. In an ideal world, the effective capacity should equal the designed capacity but this is never the case. However, the true effective porosity may be higher than predicted by Equation 3, which considers gravimetric drainage. One foot of a sand-based soil at field capacity may have less than an inch of water available to plants while a loam or a silt-clay loam may have close to 2 inches available water. Simply defined soil water holding capacity is the amount of water that a given soil can hold for crop use.Field capacity is the point where the soil water holding capacity has reached its maximum for the entire field.
