文档介绍：Brazilian technology for agriculture in Africa
The objective is to boost agricultural production by optimizing the use of farm labour and helping reduce widespread land degradation
A new FAO project in Kenya and the United Republic of Tanzania is forging links between munities and Brazilian firms specialized in production of equipment used in conservation agriculture (CA). The objective of that South-South cooperation is to boost agricultural production in both countries by encouraging a shift to CA techniques, which optimize the use of farm labour and could also help reduce widespread land degradation.
Under the three-year, Germany-funded project, up to 4,000 farmers are to be trained through participatory field schools in conservation agriculture practices, including reduced or no-tillage (NT) and the use of permanent soil cover (see box below).
Three principles...
Conservation agriculture passes a set plementary agricultural practices based on three principles:
minimal soil disturbance through reduced or no-tillage in order to preserve anic matter
permanent soil cover (cover crops, residues and mulches) to protect the soil and suppress weeds without need for chemical herbicides
diversified crop rotations and associations, which promote soil anisms and disrupt plant pests and diseases
Since dedicated CA implements - such as knife-rollers and direct seeders - are
