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...

Abstract Controlled-release nitrogen fertilizer (CRNF) can effectively enhance crop yields and raise the efficiency of in agroecosystems. In present study, volatilization NH 3 was determined by airflow enclosure chamber technique after application different CRNF rates double-cropping rice fields southern China for continuous years. The early late season (ESR LSR) were cultivated each year. resu...

The use of a controlled-release fertilizer (CRF) was studied in traditional rainfed olive grove Mediterranean climate where precipitation is very irregular, particularly the spring. objective study to assess whether CRF can improve tree's performance compared conventional nitrogen (N) (CF), by supplying N gradually and reducing risk potential loss from leaching. fertilized treatments showed bet...
