Question

Which soil has the least water retaining capacity

Answer 1

Sand soil has the least water retaining capacity.

The soil's ability to hold water depends on the size of its particles. Sandy soils have coarse particles so they have low water and nutrient holding capacities. They have good drainage.

Clay soil has the highest water holding capacity. Water molecules hold more tightly to the fine clay particles. 

Answer 2

The water holding capacity of a soil is an imperative agronomic characteristic. Soil water holding limit is controlled fundamentally by the soil surface and the soil natural matter content.

The sand soil has the minimum water holding limit the explanation for is that it has great waste however low water and supplement holding limits, the higher the level of residue and clay estimated particles, the higher the water holding limit.
