Abstract

The effect of piggery waste application on the yield and uptake of nitrogen, potassium, calcium and magnesium by ryegrass (Lolium perenne) and white clover (Trifolium repens) growing in three soils was studied in pot culture. Waste was applied six times during a 108-d growth period. The total waste applied to different treatments was equivalent to 0, 5·3, 9·4, 12·2 and 18·0 t dry matter (DM)/ha. Application of waste resulted in significant increases in the yield of ryegrass on all soils, and white clover on one soil. There was no significant decrease in yield at the highest application rate, indicating the absence of an excess soluble salt effect. Application of waste at 9·4 t DM/ha correcte..
