2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
mulching of perrenial crops (Banans and pineapples) to conserve moisture
2.2 Detailed description of the Technology
Description:
Dry vegetation is used to mulch bananas and pineapples.
Purpose of the Technology: To conserve soil moisture which is a major constraint in the area.
