The responsiveness of microbially-mediated processes such as methane oxidation to environmental change is likely to be dependent on the correct species or strains of methane oxidizers being present to exploit the new conditions. It is unclear whether the slow dispersal of microbes will limit the...

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...

Preserving biopore geometry is an important first step in evaluating its effect on the movement of water, air, and chemical substances through the soil. This is usually accomplished by making and extracting a cast of the biopore. To prevent damage to or distortion of the cast, sufficiently...
