The influence of bulk density and aggregate size on soil ,

Since bulk density is an index of packing of soil separates, and bulk density in conjunction with aggregate size decides the pore geometry in a soil system, the changes in these two properties, as brought about by various tillage and management practices, have far reaching consequences with respect to: 1) soil compaction (impedence to roots), 2)...
