Question

From the standpoint of water availability, which of the four soils; crushed silt loam, aggregate silt loam, fine sand or coarse sand would be best for the growth of most plant life? Why? There are two types of pore spaces which affect the movement and retention of air and water in soils. Which pore space type would have the greater affect on the water holding capacity of a soil?

Answer 1

Answer:

fine sand

Explanation:

• Permeability id a scientific index of the soil to have air and water pass through the soil pore and spaces. As clay soils have a fine texture, with loamy soils moderately textured and sandy soils coarsely textured thus permeability changes from slow to rapid.

• As sandy soil is highly permeable i.e 5.0 cm per hour and clay soils having the least i.e 0.05 permeability. Loamy soil is composed of sand, silt, and a smaller amount of clay.

• From an agricultural perspective, the soil permeability depends upon the percentage of the see-page and the chemical makeup of the soil. Thus crops can grow more easily this type of soil as the particle size is minute and fine.
