How much slurry can I apply?
Typically 6% DM dairy cow slurry contains 2.6 kgN, 1.2 kgP and 3.2 kgK per m3 so it is a very valuable mineral source. The P is 50% available and the K 90% available but N varies with the time of year and type of soil. Consult tables in order to calculate how much your slurry will supply. It is also important to apply within the permitted time periods and not to apply too much in order to avoid run off and potential environmental contamination.
