A Soil Can Be Amended to Reduce Minerals from Leaching

Question

A soil can be amended to reduce minerals from leaching into the water table by adding
A) humus.
B) sand.
C) mycorrhizae.
D) nitrogen.
E) silt.

Accepted Answer

Adding humus to soil can help reduce mineral leaching because it acts as a natural buffer, helping to hold nutrients in the soil and reducing the risk of them leaching into the groundwater. Humus is also able to hold onto water, which can help slow the movement of water through the soil and further reduce the risk of mineral leaching. Sand, mycorrhizae, nitrogen, and silt do not have the same ability to reduce mineral leaching.
