How about compound fertilizer for heaven and man?

Rentian compound fertilizer is good. Rentian compound fertilizer has good quality, good reputation and large sales. Humic acid black series fertilizers are produced by Qinhuangdao Tianding Chemical Co., Ltd. (formerly Zhonga Fertilizer New Product Development Company). It is a new type of high-end fertilizer specially developed by Hebei Rentian Chemical Co., Ltd. after more than 10 years of technical research, based on the "Sakefu" brand, using liquid raw materials and tubular reactor technology, especially adding highly active humic acid, some chelating medium and trace elements and patented technical additives that can promote absorption or slow release. At the same time, in order to ensure the product quality, the coin-type anti-counterfeiting label patented by Rentian Company was added in the upper right corner of the front of the packaging bag. This kind of anti-counterfeiting label is printed by the National Banknote Printing Factory, including obvious anti-counterfeiting marks such as metal lines, watermarks and ink discoloration. It can be seen that the technical content of Rentian compound fertilizer is relatively high. Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties, which plays a very important role in balancing fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops.
