|Color:||Shiny Black||Water Soluble:||99.9%|
|Appearance:||Flake||Packing:||20 Or 25 Kg/bag|
Humic acid (dry base %):65 %min
Fulvic acid:15% min
Potassium (as K2O) 8-10%
solubility in water :99.9%
huimc acid sodium can increase physiological metabolism and increase activity of invivo enzyme
Note:if overuse HA-NA is bad for your soil,so better to control.
make animal capillus bright
increase disease resistance
for medicine antiphlogistic and hemostatic
1)as carbon occupy 50%~60%,hydrogen occupy 4~6%,nitrogen occupy 1.5~6.0% in humic acid elements,and the rest mainly is oxygen.So it can rich the water.
2)Clean the water
As humic acid sodium has complex construction and many kinds of function groups,so it get high reactivity and strong adsorbability.And after application,the powder do better than flakes.
At the same time,humic acid sodium can release the ecological oxygen,it can inhibit growth of some bacterium.
4)chelated heavy metal ions
5)improve bottom characteristic,remove odour
The net structure and loose structure of humic acid sodium can free soil and improve breathability of bottom characteristic.what’s more humic acid sodium can absorb some NH3AND H2S in bottom environment.
