In this study, a novel slow-release fertilizer (SRF) consisting of kaolinite and K2SO4 was prepared, employing the process mechanochemical milling in planetary ball mill. To obtain optimum time speed, several samples were made at fixed mass ratios kaolinite: (3:1). The rotational speed ranged from 200 to 700 rpm for 120 min. Different times ranging 60 180 min 600 also investigated evaluate inco...

Abstract. Slow-release fertilizers (SRFs) are developed, to halt the nutrient loss environment, either by coating urea or infusing in a hydrophobic material. SRFs reduces release that point where single application of fertilizer can meet demand plants. Diverse range materials have already been utilized produce SRFs, however several disadvantages such hydrophilicity, non-biodegradability and cry...

Controlled-release fertilizers (CRF) are the newest and most technically advanced way of supplying mineral nutrients to nursery crops. Compared to conventional fertilizers, their gradual pattern of nutrient release better meets plant needs, minimizes leaching, and therefore improves fertilizer use efficiency. In our review of the literature, we found many terms used interchangeably with control...
