Abstract
Addition of crop residues or animal manure is needed to sustain agricultural production on inherently poor soils. This study assesses the effect of village-level interactions on carbon and nutrient flows, exploring their impact on long-term productivity of different farm types under climate variability. Increasing mineral fertiliser-use concurrently with keeping crop residues in fertile fields and allocating manure to poor fields, may boost crop and cattle productivity at village level. In communal areas of NE Zimbabwe, feed resources are collectively managed, with herds grazing on grasslands during the rainy season and on crop residues during the dry season.
