What are the ways of attaining soil fertility?
1 of 1
Recycling organic wastes, e.g. manure, night soil and crop residues by returning them to the field, either directly or treated (composted, fermented, etc.).
Handling organic fertilizers in such a way that nutrients are not leached by excessive rain or volatilized by high temperature or solar radiation.
Reducing run-off and soil erosion, which removes nutrients and organic matter.
Reducing burning of vegetation when farming is intensified, as this leads to losses of organic matter;
Reducing leaching by maintaining a high humus content in the soil, soil cover and intercropping plant species with different rooting depths.
