Question

discuss how soil structure deterioration can affect soil porosity and permeability

Answer 1

Answer:

Soil porosity refers to the fraction of the total soil volume that is taken up by the pore space (Nimmo, 2004). Mainly, pore spaces facilitate the availability and movement of air or water within the soil environment. Four hierarchical pore structures have been characterized as macropores, pore space between macro-aggregates, pores between micro-aggregates but within macro-aggregates, and pores within micro-aggregates in the soil environment

Answer 2

Soil texture and structure greatly influence water infiltration, permeability, and water-holding capacity.For example, a fine soil has smaller but more numerous pores than a coarse soil. A coarse soil has bigger particles than a fine soil, but it has less porosity, or overall pore space.

hope this will help u dr ❤
