Dry fertilisers of biologically degraded crushed minerals such as limestone, rock, or rock phosphate together with micro-organisms, including one or more selected supplementary trace elements, are described. Minerals, some sawdust, an inoculum, and nutrients or other protein material, including bound selected micro-elements or trace elements are stored under aerobic conditions for some weeks during thermophilic biological degradation. The resolution fertiliser releases the macro-elements and micro-elements over a long period of time. The microelements are include within a biomass of micro-organism (5-6% carbon in the resulting fertiliser) and are more effective in remedying plan or animal deficiencies than if administered as inorganic salts. Furthermore this fertiliser avoids leaching of mineral including phosphate (phosphorus) and microelements into groundwater, streams, rivers or lakes. |
