1)improve the effect of nitrogen fertilizer
We use carbonic acid and urea for the main nitrogen fertilizer.However ammonium nitrogen is unstable,and volatilizes easily.As humic acid contains abundance of active functional groups such as carboxyls and phenolic hydroxyls,so it can reduce the ammonium nitrogen lose for its strong ion-exchange capacity and absorb capacity.
2)improve the effect of phosphatic fertilizer
In acid soil,the phosphatic is mainly fixed by ferric ion and aluminium ion.and in calcareous soil,phosphatic will be fixed by calcium ion.So the use ratio of phosphatic in this season will be only 10-20%.after we use humic acid fertilizer,it will inhibit the fixed water soluble phosphatic in soil.what’s more,it will promote the root to absorb phosphatic.
3)improve the effect of potash fertilizer
Humic acid contain the function groups which can absorb and store potash ion.So it can avoid potash ion will run away in water in sandy soil or eluvial soil and be fixed in clayed soil
