Abstract

A fertiliser comprises a mixture of pressed slurry and milled peat with the slurry comprising a major proportion by weight. The invention also provides a process for the production of a fertiliser comprising the steps of (a) providing dried slurry by pressing the slurry to remove a substantial proportion of liquid and moisture, and; (b) mixing the dried slurry with a proportion of milled peat. The fertiliser may also comprise a proportion of seaweed.

Description

IMPROVEMENTS IN FERTILISER The present invention relates to improvements in fertiliser and in particular to fertiliser which is substantially purely organic.
A problem on some farms is the amount of slurry which is produced by cattle. In many cases this slurry is of a volume much greater than that required for use on the farmlands. Slurry, of course is extremely difficult to handle or transport and therefore some land may be virtually destroyed by the farmer trying to dispose of the slurry by simply dumping it onto the land.
In addition, it is known that slurry may be advantageously used as a fertiliser and thus it is uneconomic to dispose of the slurry as waste.
An object of the present invention is to overcome the above problems.
According to the present invention there is provided a fertiliser comprising a mixture of pressed slurry and milled peat with the slurry comprising a major proportion by weight. In a preferred form of the invention the mixture further includes a proportion of seaweed.
In one embodiment of the invention the fertiliser comprises 60% to 75% by weight of pressed slurry and 25% to 40% by weight of milled peat. The fertiliser further preferably includes approximately 1% to 15% by weight of seaweed.
In a particularly preferred embodiment of the invention, the mixture comprises the following approximate proportions by weight; pressed slurry 63%, milled peat 32% and seaweed 5%.
This particular combination of constituents has been found to have particular advantages including providing excellent fertilisation for the earth and also being of an optimum consistency for packing and handling by the end user. It will be appreciated that if the fertiliser comprises too much pressed slurry this may be difficult to pack and handle.
The invention further provides a process for the production of a fertiliser comprising the steps of, producing dried slurry by pressing slurry to remove a substantial proportion of liquid and moisture and, mixing the dried slurry with a proportion of milled peat.
The slurry preferably comprises slurry which is formed from the waste products of cattle fed mainly on grain type foods.
Slurry generally comprises a solid or semi-solid part and a liquid part. The slurry is preferably obtained by collecting slurry in a tank so that the solid or semi-solid material in the slurry collects in the tank below the liquid part. The liquid part is then pumped away and the solid or semi-solid part is readily collected for use in the fertiliser. The solid or semi-solid part is then removed from the tank and passed -through a suitable pressing apparatus to remove a substantial proportion of the liquid and moisture from the solid or semi-solid part. Any suitable pressing apparatus for example rollers, may be utilised for pressing the slurry and this is preferably carried out on a continuous basis with slurry being passed through the rollers for example, on a conveyor apparatus.
The dried slurry is admixed with milled or ground peat which is preferably also substantially dried. The slurry and peat may be admixed in any suitable mixing apparatus.
The advantage of the invention is that the improved fertiliser, provides a suitable and economically advantageous means of utilising excess farm slurry. In addition, the improved fertiliser produced is substantially free of any concentrated chemical additives which are present in most artificial fertilisers. The improved fertiliser is thus particularly attractive to those who wish to use it as an organic fertiliser, for example, for those who claim to be producing organically grown crops.
The seaweed provides a measure of trace elements which may be-desireable for the land in which the fertiliser is used.
