Abstract

Abstract

Various degrees of compaction were carried out prior to and immediately after planting a summer crop of sorghum under conditions of dryland farming. Soil physical properties—bulk density, penetrability, air permeability and surface cracking—were affected appreciably only to a depth of 15 cm. Preplanting compaction significantly reduced seedling emergence and yields. Postplanting treatments increased sorghum stand density and yield significantly.
