About Us

Changsha Zheng Li Biological Technology Co., Ltd. relies on Hunan Agricultural University, Ningxia University and Chinese Academy of Sciences and other research institutes, specializing in research & development, manufacturing and trading of humic(humus) acid/huminsauren products for poultry/swine/aquaculture and other animal therapeutic nutritional ingredients/additives/supplements/material as well as fertilizers for nearly 15 years. Our factories are certified with ISO9001:2015 and inspected by ITS, SGS, TUV, AQM, BSCI etc. Our products are widely used in livestock and poultry feed, animal feed additives, aquatic animal protection, organic fertilizers, soil improvement, industrial ceramics and biomedicine industries.

Changsha Zheng Li Biological Technology Co., Ltd. has two major production bases around Wuhai City, Inner Mongolia, a well-known high-quality humic(humus) acid/huminsauren base in the country. The rich coal resources here breed high-grade humic(humus) acid/huminsauren raw materials. Our factories have a total area of more than 90,000 square meters, with first-class humate production equipments and technicians and adopt advanced production techniques such as precise feeding, efficient activation, and drum drying to strictly control product quality.
The company’s leading products are: sodium humate, feed grade sodium humate, feed grade coated sodium humate, neutral sodium humate, potassium humate, magnesium humate, silicon humate, phosphorus humate, humic(humus) acid/huminsauren Ammonium, boron humic(humus) acid/huminsauren, nitrohumic(humus) acid/huminsauren, humic(humus) acid/huminsauren urea, potassium fulvic acid, anti hard water potassium fulvic humate, mineral fulvic acid, mineral fulvic acid potassium, activating biological organic fertilizer, microbial agent, water-soluble Fulvic acid fertilizer, element water-soluble fertilizer, etc., many of which have obtained exclusive patents.

Based on local high-quality humic(humus) acid/huminsauren raw materials, our Wuhai factories in Inner Mongolia are market-oriented based on science and technology and focusing on product quality in expanding the market. The products are sold to most parts of the China and exported overseas. In 2018, our group invested more than 20 million RMB in using waste steam as power & heat and applies complete automated control for material reaction. The screw quantitative conveying of central control management is adopted while the control error of the weathered coal material management control is not more than 5‰ as well as water and alkali are also quantitatively controlled, which avoids the forklift to invert the mixing tank and reduces the error. The centrifuge equipment used in the production ensures that the water-insoluble content of the product is below 2%. Products can be traced, and product quality, production capacity, and product prices have greater advantages. Our factories actively respond to the national environmental protection policy and effectively recycle energy, which is a project with great market competitiveness.
