Abstract
Tillage operations are expected 10 improve the soil macrostructure (c1oddiness) and aggregate strength of dispersive soils that have low organic matter conteD! and bulk density. Likewise residue mulching reduces rainwater losses through runoff and evaporation by its mulching effects. dissipation of raindrop energy and reduction of overland flow velocity. These soil surface conditions are favourable 10 the improvement of infiltration and subsequent conservation of moisture within the soil. The seasooal trends in profile soil moisture under these practices. would show whether the moisture available would sustain crop growth during critical dry spell periods.
