Description of practice

In the practice of in situ composting crop residues, green and farmyard manures, organic waste and ashes are composted in the field in trenches or pits. Crops are directly grown on or next to the pits which also serve to harvest rainwater and regulate soil moisture. Organic matter recycling like this can be developed into a circular system, depending on what materials are available locally.

AMP70 01

In situ compost cultivation

Trenches (0.6 m x 0.6 m and 0.9 m apart) are dug across the slope, filled with organic residues and backfilled with soil until slightly below the soil surface to capture runoff. Water and nutrient demanding crops are grown in the trenches, leguminous crops in between.

AMP70 02

Kibanja cropping system

Compost pits (3 x 3 m in size and 0.6 m deep) are dug between 4 widely spaced banana plants and filled with farm manure, crop residues and ash. They are covered with soil to activate nutrient release though microbial disintegration and avoid volatilization of greenhouse gases.
