Influence of a Root Crop on Physical Properties of a Medium-Textured Soil1

Studies to evaluate the influences of stage of growth of a root crop and two plant densities on certain physical properties of a medium-textured soil were conducted. Dynamic changes with time, depth, and plant population occurred on selected physical properties of medium-textured soils being cropped to fall radishes. After 2 months, radish roots compacted and decreased the permeability of the top 15 cm of soil but had little influence at the 15- to 30-cm depth. However, after 4 months the enlarged radish roots decreased the compactness and increased the permeability of the top 15 cm of soil but compacted the soil at the 15- to 30-cm depth. Field measurements of soil strength described the zone of compaction by radish roots. Compaction by double row radishes was significantly greater than by single-row radishes.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
