Liquid effluents can be applied to arable or grassland fields. It is normal to inject the material below the surface for grassland, except where the land is not going to be grazed or cut for a couple of months.

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.

This material also contains a useful compliment of Sulphur, which in combination with the Nitrogen fraction may work to improve grass growth. There is also a small amount of Magnesium that will help, particularly on grazing land, to reduce the risk of grass staggers. It will not be sufficient to eliminate the problem where a significant deficiency exists.

Normal applications are in the region of 100 tonnes per hectare (40 tonnes per acre) At these rates the soil will receive a total of 105 units per acre of Nitrogen, 46 units of Phosphate and 88 units of Potash. The Nitrogen is almost exclusively slow-release.

Note that the table shows PHOSPHORUS as 25.3 kgs. To convert this to PHOSPHATE, multiply by 2.291. POTASSIUM is converted to POTASH by multiplying by 1.205.
