Both of fertilisers contain the different amounts nutrients. The MKP-fertiliser includes only mineral phosphorus compounds that are totally dissolved. The MKP-fertiliser has the high concentration of available phosphorus, but there is no organic matter. On the other hand, the MKP-fertiliser is acidic. EC values in MKP fertiliser solution is low because it is consisted of other minerals and soluble ionic constituents is only potassium and phosphoric acid compounds. The cation of MKP-fertiliser is only potassium ion. To simulate the adsorption of phosphorus through soil from different fertilisers source, the MKP-fertiliser is prepared by dissolved into tap water. The summary of chemical and organic manure fertiliser solutions are given in Table 4.4.
