In  response to the remediation needs of complex systems in different polluted and degraded soils, a series of high-value targeted humic acid environmental materials have been created through controllable cross-linking polymerization reactions of biological humic acid, and the controllable cross-linking polymerization reaction process and equipment of biological humic acid have been invented. Industrial continuous production of targeted humic acid environmental materials; A series of targeted humic acid environmental materials have been demonstrated and promoted in more than 20 provinces and cities. The field application results show that targeted humic acid environmental materials can improve soil properties, improve crop quality and yield, achieve sustainable restoration of degraded soil, and achieve social and environmental benefits. Significant benefits.
