Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
Profitable and sustainable nutrient management systems for East and Southern African smallholder farming systems: challenges and opportunities: a synthesis of the Eastern and Southern Africa situation in terms of past experiences, present and future opportunities in promoting nutrients use in Africa
(CIAT; The University of Queensland; QAAFI; CIMMYT, 2013)
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 ...
Weed control in conservation agriculture systems of Zimbabwe: Identifying economical best strategies
Weed management under conservation agriculture (CA), especially when manually controlled is one of the major setbacks for the widespread adoption of CA in southern Africa. This study was conducted at three on-station and ...
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, ...
Maize-based conservation agriculture systems in Malawi: Long-term trends in productivity
In Malawi and throughout much of Africa, maize yields have declined over the past several decades due to continuous cultivation, often in monocropping with little or no inputs. As a result, soil degradation has been ...
Rotation in conservation agriculture systems of Zambia: Effects on soil quality and water relations
Conservation agriculture(CA) systems are based on minimal soil disturbance, crop residue retention and crop rotation. Although the capacity of rotations to break pest and disease cycles is generally recognized, other ...
Conservation agriculture in eastern and southern provinces of Zambia: Long-term effects on soil quality and maize productivity
Sustainable and resilient cropping systems are required in southern Africa to arrest declining soil fertility and offset the future negative effects of climate change. Conservation agriculture (CA) has been proposed as a ...
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 ...
Benefits and challenges of crop rotations in maize-based conservation agriculture (CA) cropping systems of southern Africa
Conservation agriculture (CA) based on minimum soil disturbance, crop residue retention, crop rotations and associations are being promoted in southern Africa to reverse the decline in soil fertility and crop productivity. ...
