Conservation agriculture systems for Malawian smallholder farmers: long-term effects on crop productivity, profitability and soil quality

Conservation agriculture (CA) systems are based uponminimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce production costs. This study examines the effects of CA practices on crop productivity, profitability and soil quality under the conditions encountered by smallholder farmers in t...

Conservation Agriculture Improves Soil Quality, Crop Yield, and Incomes of Smallholder Farmers in North Western Ghana

Conservation agriculture (CA) practices are being widely promoted in many areas in sub-Saharan Africa to recuperate degraded soils and improve ecosystem services. This study examined the effects of three tillage practices [conventional moldboard plowing (CT), hand hoeing (MT) and no-tillage (NT)], and three cropping systems (continuous maize, soybean-maize annual rotation, and soybean/maize int...

Assessing Soil Quality in Organic Agriculture

Soil and crop management under conservation agriculture in Zimbabwe

Carbon mitigation strategies and mechanisms have been globally implemented in an attempt to prevent catastrophic climate change. Kyoto targets require reductions in greenhouse gas emissions and increases in carbon sequestration. Although a number of carbon neutral technologies have been adopted such as bio-fuel and alternative energies, these currently fail to meet global requirements. An innov...
