The correct answer is option A

Soil reaction can be defined as the measure of acidity or alkalinity of soil. The pH of the soil or the reaction of the soil is an measurement or indication of the alkalinity or acidity of the soil. This defines the nature of the soil, whether the soil is acidic or basic in nature. If the amount of hydrogen ions is more then the soil is acidic and if the amount of hydrogen ions are less then the soil is basic.

Write a difference between compost and green manure
