This product is a natural additive for fertilizers to improve the
structure of the soil and increase the fertility with slow release
effect, contains around more than 70%humic acid.

1) Optimize the structure of soil to increase the buffering power
and fertility .
When the soil is less fertile also sandy to some extent ,humic acid
will increase its cation exchange capacity to retain water and
beneficial micro nutrient ,accordingly largely increase the
fertility of soil.Under heavy and compact conditions,Humic acid
will work with fungi to construct a crumb structure root to absorb
water oxygen and nutrient also improve root penetration.
2) Neutralize both acidic and alkaline soil to release the
beneficial metal iron, thus promote absorption by plants.
When the soil is alkaline, many beneficial metal iron and other
trace elements can not be absorbed by plants,humic acid can buffer
the pH and convert the nutrients and trace elements into absorbable
form and promote their uptake by the roots.
When in acidic soil, humic acid will tremendously reduce the toxins
such as the ally aluminum and heavy metals, which will be bonded
firmly and immobilized ,thus their toxicity is reduced and
phosphate is bonded by aluminum is released.
Under Salinalised soil: Salts are split up by the high cation
exchange capability, cation (eg.Ca, Mg) are bonded and chelated.
3) Promote plants growth also largely increase the yield and
