Abstract
A method to obtain suspended fertiliser from two-step olive oil mill process wastes (alperujo) is shown. For it, an extraction with KOH to pH=13 from this by-products is taken, and later neutralisation with nitric acid HNO{sub 3} to pH=7.5 and with phosporic acid H{sub 3}PO{sub 4} to pH 6.5. The fertiliser obtained contains the humic fraction extracted, and show Nitrogen, Phosphorous and Potassium contents of 0.8-1%, 0.5-0.8%, 3-4%, respectively and a density of d=1,18 g/cm''3, and may be used as raw material to manufacture other organo-mineral fertilisers.
