The use of limited organic resources to build resilience to drought in semi-arid regions was investigated using systems modelling. The study focused on Halaba in Ethiopia, drawing on biophysical and socio-economic data obtained from a survey of farms

Time results in large changes to soil infiltration characteristics due to weather, mechanical stability and the action of biology. Even as the water status changes in a wetting soil, swelling may alter infiltration characteristics. Our laboratory has

Typically, when investigating physical constraints to root growth, a homogeneous soil is used. The aim of this study was to compare root and shoot growth under controlled unstructured and structured soil conditions.

Rural cooperatives in China have been flourishing and diversified, but their functions and roles in enhancing knowledge exchange and social learning is still unclear. This paper adopts an integrated framework for knowledge management to examine the i

Agricultural soil structure can vary markedly over a growing season, whether it be from the slumping of seedbeds in cultivated soils or the action of plants and weather under zero-tillage. Water retention and transport properties therefore also vary

Soil has a spatially heterogeneous mix of weaker and stronger elements, and larger and smaller pores. When studying physical constraints to root growth, however, most studies use sieved, repacked soil to create a more homogeneous environment that is

Soil aggregates fracture through the coalescence of internal macropores (cracks), forming smaller fragments that change pore structure characteristics. Many studies have measured soil aggregate fracture with laboratory tests, but the impact of intern
