Conservation Agriculture produces mixed outcomes on degraded and weed-infested soils

In tropical Africa, conservation agriculture practices can address common production constraints on smallholder farms. In Madagascar, scientists Rodenburg et al. combined no-till and cover crops practices during a rice-maize rotation on Striga weed-infested soils. They observed soil nitrogen increments and steep reductions in soil erosion. The yield was moderate for rice but low and variable for maize.
