Experiments on the fertiliser value of animal waste slurries

Smith, K. A.; Unwin, R. J.; Williams, J. H.

A review is presented of the fertiliser value of animal waste slurries according to experimental work in the United Kingdom. Results of studies undertaken by MAFF staff since 1962 are compared with the results of other workers. Agronomic experiments have demonstrated variable growth responses, particularly of grass to nitrogen applied in cattle slurry. Results suggest that frequent doses of dilute slurry are more effective than single dressings of high dry matter material.
