Different countries have different climates, soils, and water quality, and a single fertilizer type is increasingly unable to meet customer needs. In order to meet the growing demand, Qingdao Future Group proposed the "fertilizer OEM service" in 2015, which is to produce fertilizers according to the customer's fertilizer specifications. Customized fertilizer refers to the mode in which growers choose fertilizer varieties according to soil characteristics and crop types, comprehensively consider various elements required in the process of crop growth, and then entrust manufacturers to produce.
