2.1 技术简介

技术定义:

The technology that applies contouring, mulching and intercropping in SWC.

2.2 技术的详细说明

说明:

Agronomic technology is used to control soil erosion during the crop production period, i.e. method that is employed to improve soil fertility, conserve water and protect from soil erosion while the land is under crop production.

Purpose of the Technology: The purpose is to keep the fertility of the soil stable by protecting the soil from soil erosion and water loss.

Establishment / maintenance activities and inputs: The establishment is either done by planting strong root crops in between cultivated areas, or leaving the soil uncultivated, with a mulch cover on the soil surface. This will be maintained by keeping the intercrop strong and healthy while using zero or minimum tillage without removal of left over material on the soil surface.
