Gone are days when farm slurry seen as waste product
However, due to the increase in the price of fertilisers, and better understanding of the nutrients in slurry, it is now regarded as very valuable. Based on current fertiliser prices, Teagasc puts a value of well over €20 on 1,000 gallons of good quality slurry, used efficiently.
Pig slurry and cattle slurry have similar total values, but have very different levels of nutrients. Average cattle slurry contains 15% nitrogen, 17% phosphorous (P) and 68% potash (K) on a dry matter basis, varying according to the nutrients being fed to cattle. Good quality pig slurry contains 43% N, 22% P and 35% K.
