The role of macropores on rooting pattern and movement of water and solutes in various field soils



The role of macropores on rooting pattern and movement of water and solutes in various field soils



Transactions 14th International Congress of Soil Science, Kyoto, Japan, August 1990, Volume II: 130-135



The distribution of visible macropores and wheat roots were investigated on a horizontal grid every 10 cm to a depth of 55 cm in acid brown forest soils, pseudogleys, gray lowland soils, sand dune regosols, and andosols around Sapporo. The distribution of both macropores and roots was more uneven in clayey soils than in sandy or loamy soils. Fractal analysis of the distributions showed that macropores contributed greatly to root elongation.
