how could soil fertility be increased
Answers
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose
These include fallowing, using compost, manure, crop residues, fertilizer trees (e.g Calliandra and Pygeum africana), intercropping legumes with cereals and including the principles of conservation agriculture (crop rotation, ensuring permanent cover for the soil and no disturbing of the top soil layer
