Abstract | A technique was developed to produce organomineral fertilisers (OMF) using biosolids granules coated with urea and potash. Two OMF formulations with the following N:P2O5:K2O compositions: 10:4:4 (OMF10) and 15:4:4 (OMF15) were developed for application in grassland and arable crops. Routine fertiliser analyses were conducted on OMF and biosolids samples, and compared with a sample of urea to determine key physical and chemical properties of the materials which affect handling and spreading, soil behaviour and fertiliser value. Bulk and particle densities were in the range of 608 to 618kg m-3, and 1297 to 1357kg m-3 respectively. Compression tests showed that OMF particles undergo deformation followed by multiple failures without disintegration of the granules when vertical load was applied. This behaviour was attributed to the moisture content (�15% w w-1) and the organic nature of the material. Static particle strength was between 1.14 and 6.31 Nmm-2 depending on the particle diameter. The use of a model for fertiliser particle distribution studies showed that OMF granules should be between 1.10 and 5.50mm in diameter with about 80% of the particles in the range of 2.25 to 4.40mm to enable application at 18m tramline spacing. This research is novel as it utilises technology to improve fertiliser value of biosolids to increase usage by farmers, reduce disposal costs and deliver the range of environmental benefits associated with recycling. |
