Influence of a Root Crop on Physical Properties of a Clay Soil1

Abstract

Abstract

Studies to evaluate the influences of stages of growth of a root crop and two plant densities on certain physical properties of a swelling clay were conducted. selected physical properties of the swelling clay soil changed with time and depth. Bulk density of clay soil decreased during growing season. Density of soil was higher at 15 to 30 cm than in the top 15 cm of soil. Permeability of the 15- to 30-cm depth was considerably less than top 15 cm of soil. Root development and drying due to evapotranspiration appeared to increase the permeability of the top 15 cm of soil but had little influence on permeability of soil at the 15- to 30-cm depth. Field soil strength data indicated radishes compacted the soil from a 10- to a 30-cm depth.
