Typical Dairy Sludge Cake

There is a need to maintain organic matter levels in the soil if the best is to be achieved from other fertiliser inputs. Recent studies have indicated a loss of some 18% of organic matter from arable soils over the past 10 years. A rich, humid soil will lose less of its essential crop nutrients and moisture. It will also be easier to cultivate, and will be less prone to drought.

Typical Dairy Sludge Cake has over 60% of its dry solids as organic matter. It is also rich in Nitrogen and Phosphate.

As can be seen from the table above, there is a substantial compliment of major crop nutrients and organic matter derived from applications of Typical Dairy Cake.

Normal applications are in the region of 20 tonnes per hectare (8 tonnes per acre) At these rates the soil will receive a total of 131 units per acre of Nitrogen, 180 units of Phosphate and 4.5 units of Potash.

Note that the table shows PHOSPHORUS as 98.56 kgs. To convert this to PHOSPHATE, multiply by 2.291. POTASSIUM is converted to POTASH by multiplying by 1.205
