Abstract
Samples were taken at two depths from a sandy soil receiving slurry or farmyard manure (FYM). Analysis indicated that inorganic nitrogen (N) and to a lesser extent potassium (K), moved rapidly through the soil, particularly in the winter months. Slurry was separated into liquid and semi-solid fractions. The liquid could be applied to a growing crop through an irrigation system. It was applied to Italian ryegrass (cv. Augusta) at a rate of 50 m3 ha-1 yr-1 in three applications and gave a yield response equivalent to about 180 kg N ha-1 supplied as ammonium nitrate. However, the liquid fraction applied late in the season significantly increased the copper (Cu) content of the grass.
