ABERYSTWYTH LIQUID DIGESTED SLUDGE

Liquid effluents can be applied to arable or grassland fields. It is normal to inject the material below the surface for grassland.

The crop nutrients are rapidly incorporated into the soil and can be taken up by crops almost immediately. Much of the Nitrogen in this material however, is held in the organic fraction of the effluent and will release slowly to the crop over a period of months. Because it is bound up in the organic matter, it does not easily leach out of the soil, and can continue to feed the crop throughout the growing cycle.

Determinand	Value	Units	Addition / Tonne (Wet)	Addition / 80t Dressing

Dry Matter	4.82	%

Total Nitrogen	6.48	% w/w	3.12 kg	249.87 kg
Total Phosphorous	2.57	% w/w	1.24 kg	99.10 kg
Total Potassium	0.5	% w/w	0.24 kg	19.28 kg

Organic Matter	39.1	% w/w	188.5 kg	15077 kg

Normal applications are in the region of 80 tonnes per hectare (32 tonnes per acre) At these rates the soil will receive a total of 200 units per acre of Nitrogen, 182 units of Phosphate and 18 units of Potash.

Note that the table shows PHOSPHORUS as 99.1 kgs. To convert this to PHOSPHATE, multiply by 2.291. POTASSIUM is converted to POTASH by multiplying by 1.205.
