Which soil can’t hold water holding water for a long period of time?
A
silt
B
clay
C
sand
D
humus
Explanation: 

Detailed explanation-1: -Sand does not hold any water and clay particles hold water so tightly to the particle surface that plant roots are unable to extract it from the soil. Silty soils are also heavier than sandy soils, and holds up nutrients and make it better for crop cultivation.

Detailed explanation-2: -Particle Size Clay soil has small, fine particles, which is why it retains the most amount of water. Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water.

Detailed explanation-3: -The larger the surface area the easier it is for the soil to hold onto water so it has a higher water holding capacity. Sand in contrast has large particle sizes which results in smaller surface area. The water holding capacity for sand is low.
