Influence of organic waste amendments on selected soil physical and chemical properties

Sandy, infertile soils can benefit From the addition of organic waste amend ments. Annual applications of organic wastes for as long as 4 yr increased soil organic matter content, decreased soil bulk density, and increased soi l water retention of a coarse-textured soil. However, soil water-holding ca pacity was not necessarily increased, and there was a limited effect on soi l cation exchange capacity.
