Effects of conservation agriculture techniques on infiltration and soil water content in Zambia and Zimbabwe
The adoption of cropping systems (CA), based on minimal soil movement, permanent soil cover with crop residues or growing plants and crop rotation has advanced rapidly in the Americas and Australia over the last three ...
Investigating Conservation Agriculture (CA) Systems in Zambia and Zimbabwe to Mitigate Future Effects of Climate Change
Most models predict that climate change will affect the southern African region both through temperature rises and increased frequency and severity of drought. Conservation agriculture (CA) based on minimal soil disturbance, ...
The sustainability of a groundnut plus maize rotation over 12 years on smallholder farms in the sub-humid zone of Zimbabwe
An experiment was conducted on four smallholder farms and on-station in the sub-humid zone of northeast Zimbabwe for 12 years to assess how the rotation of groundnut with NPK-fertilized and unfertilized maize affected the ...
A comparative analysis of conservation agriculture systems: Benefits and challenges of rotations and intercropping in Zimbabwe
Increasing soil degradation in southern Africa and the potentially negative effects of climate change demand ?greener? solutions to reverse this trend. Conservation agriculture (CA) has been proposed as one of those solutions ...
Nitrogen effects on maize yield following groundnut in rotation on smallholder farms in sub-humid Zimbabwe
Rotating maize (Zea mays L.) with groundnut (Arachis hypogaea L.) has been proposed as a way to maintain soil fertility and prevent maize productivity declines in the smallholder cropping systems of sub-humid Zimbabwe. ...
Smallholder farmer management impacts on particulate and labile carbon fractions of granitic sandy soils in Zimbabwe
Crop production in maize-based smallholder farming systems of Southern Africa is hampered by lack of options for efficiently managing limited and different quality organic nutrient resources. This study examined impacts ...
