Zero growth of chemical fertilizer consumption has become a target of Chinese government as per the Central Government Work Report presented by Chinese Premier Li Keqiang on March 5, 2016. This is a historical issue in the agriculture development of china. Now humans care more about soil health, food security, ecological environement and sustainable development of agriculture.  

Zero growth of chemical fertilizer consumption has become a national policy. This is a revolution of fertilizer application concept. The revolution is not simply repeating the use of the farm manure and organic fertilizers. It will come to a new era: focus more on both organic and inorganic fertilizers in agricultures.  
 Regading soil, fertilizers, and crops, the organic matter is certainly very good, but the current organic matter is not equal to the traditional organic matter. How to choose the safe organic matter? Humans have turned their eyes to humic acid. Humic acid is the original substance of soil, the core productive force, and the basis of cluster structure of soil.
Researches and practices have proved that the industrially extracted humic acid has the same properties as the soil humic acid. Applying the industrially extracted humic acid to combine with the fertilizer will have very good effect. Humic acid+ will become a new hot spot and the Fertilizer 4.0 era will come based on humic acid +.
