Slurry is a valuable source of nitrogen (N), phosphorus (P) and potassium (K) and its effective use on farms can help reduce fertiliser costs. To maximise the nutrient value of either cattle or pig slurry, a number of decisions should be made over the coming weeks as to where on the farm slurry is required and consider application timing and techniques to maximise N recovery.Targeted early application of slurry based on soil test results will ensure efficient use of slurry N and that early-season P and K requirements are satisfied.
