We estimated a normalized translog yield-response model using African farm-household survey data to compare the yield of smallholder maize production under integrated soil fertility management (ISFM) and chemical-based soil fertility management. Controlling for other factors, maize yield...

The potential spreading of antibiotic resistance genes (ARG) into agricultural fields and crops represent a fundamental limitation on the use of organic fertilization in food production systems. We present here a study of the effect of spreading four types of organic soil amendments (raw pig...

Continuous inputs of organic matter are vital for sustaining soil organic carbon (SOC) and productivity of soils in smallholder crop-livestock systems. However, the dynamics of the different inputs i.e. maize shoots, roots and manure used are poorly understood. Along with organic inputs, use of...
