Organic acid coated-slow-release phosphorus fertilizers improve P availability and maize growth in a tropical soil

In this paper, we report the results of studies on the solubility (water solubility trial) and the response by plants (greenhouse pot experiment using Zea mays) for four types of monoammonium phosphate fertilizers (Conventional MAP - MAP1, MAP coated with a natural organic acid - MAP2, MAP coated wi...
