2.1 技术简介

技术定义:

Soil erosion control for annual crops in flat land using intercropping.

2.2 技术的详细说明

说明:

This technology involves growing of minor crops with major crops. More than one crop is grown on the same piece of land. The land user we visited had managed beans in a banana plantation . He used light labour during weeding and harvesting season.

Purpose of the Technology: The purpose of practicing intercropping was to reduce soil erosion , to increase agricultural outputs, to raise water holding capacity in the soil.

Establishment / maintenance activities and inputs: Establishment: sowing of seeds was done through use of light labour . Minor seeds were sown with major seeds like beans with banana plantation.

Weeding: Is also done in the middle of the season , leguminous crops are planted to maintain the soil fertility.

Various inputs are used , e.g.. hoes, pangas and light labour.
20 persons were used and each paid Shs 10000 per week.

Natural / human environment: The nature of the area /village where the technology is being practiced is a flat area with loamy soils.

The area receives two rain seasons in a year.

This village has 160 households (Kijonjo village) 55% of farmers have already adopted this technology.
They normally grow annual & perennial crops like banana, coffee, beans and ground nuts purposely for commercial and subsistence purpose.

Main causes of degradation: soil management (soil was poorly managed due to monoculture practice.), change in temperature (lead to death of living organism that are used in soil formation.), poverty / wealth (lead to deforestation to earn a living.)

Secondary causes of degradation: deforestation / removal of natural vegetation (incl. forest fires), over-exploitation of vegetation for domestic use (most trees whic are supporting soil were reduced.)
