Question

Describe five ways of soil acidification and alkalization.

a) Adding lime, using nitrogen-based fertilizers, acid rain, crop residues, organic matter

b) Crop rotation, using phosphorus-based fertilizers, volcanic eruptions, deforestation, weathering of minerals

c) Over-irrigation, using potassium-based fertilizers, erosion, industrial pollutants, sewage disposal

d) Composting, cover cropping, afforestation, using magnesium-based fertilizers, microbial activity

Answer 1

There are several ways in which soil can undergo acidification or alkalization. Soil acidification can occur through adding lime, using nitrogen-based fertilizers, acid rain, crop residues, and organic matter. Soil alkalization, on the other hand, can be caused by crop rotation, using phosphorus-based fertilizers, volcanic eruptions, deforestation, and weathering of minerals.

Step-by-step explanation:

The process of soil acidification and alkalization can occur through various ways. Five common ways of soil acidification include adding lime, using nitrogen-based fertilizers, acid rain, crop residues, and organic matter. On the other hand, five ways of soil alkalization include crop rotation, using phosphorus-based fertilizers, volcanic eruptions, deforestation, and weathering of minerals.
