Abstract

Tillage and compactive processes affect soil-hydraulic properties and soil-water flow. Soil-water retention and transport properties are altered in response to changes in pore geometry. Soil-water flow is affected not only by soil-hydraulic properties but additionally by the distribution of sources and sinks of water in the soil system. Tillage and compaction can alter soil-pore geometry, and they can also affect sources and sinks of water by changing surface configuration, surface residue cover, and crop rooting distribution. This paper reviews literature and presents data and relationships showing the effects of tillage and compaction on soil-hydraulic properties and water-flow, presents numerically modeled water-flow for some tillage management systems, and identifies future directions for tillagerelated hydrologic research.
