Organic media are derived from natural organic materials, which are coconut dust, simple coconut dust, or those containing coconut staple fibers, coconut pericarp chips, and are beaten bark, which is both broadleaf trees and needleleaf trees, and sawdust. These natural organic materials contain a lot of organic acids and salt (NaCl). The feature of the present invention is treatment using the modifying reagents to eliminate the organic acids and salt that adversely affect the cultivation of plants. The modifying reagents consist of at least one salt selected from among iron salts and aluminum salts, and the modified organic media obtained by modifying the natural organic materials with the modifying reagents. The natural organic materials are preferably coconut dusts, beaten bark, and sawdust. The modifying materials of 0.1 to 5 g is preferably applied to the natural organic materials of 100 g in dry weight.
A modified organic compost for cultivating planting trees and flowers obtained by treating coconut dust with a modifying reagent containing at least one salt, in the amount from about 0.1 g to about 5 g per 100 g (in dry weight) of the coconut dust, selected from the group consisting of iron salts and aluminum salts which can chemically react with phenolic acids, wherein an extracted amount of the phenolic acids in the modified organic compost after the treatment is no more than 1000.3 mg/kg.
