IMPROVEMENT OF PHOSPHATE FERTILIZATION METHOD IN WETLAND RICE
AGRIVITA Journal of Agricultural Science, 2014 The low efficiency of Phosphate fertilization on wetland rice may be overcame by using quickly dissolve P fertilizer. However, for soils containing high dissolve Fe, such as Alfisol and Oxisol, will induce the formation of Fe-P bonding. Therefore, to use
