Main Function

1.As carriers and activators of  foliar and irrigation fertiliser .

Their application in combination with trace elements and other plant nutrients, as foliar sprays, can improve the growth of plant foliage, roots, and fruits.

2.Increase carbohydrates content of the leaves and stems.

These carbohydrates are then transported down the stems into the roots where they are in part released from the root to provide nutrients for various soil microorganisms on the rhizoplane and in the rhizosphere. The microorganisms then release acids and other organic compounds which increase the availability of plant nutrients. Other microorganisms release “hormone like” compounds which are taken up by plant roots..

3.Increase fertilizer application efficiency.

In combination with nitrogen, potassium, phosphorus and various trace minerals have been demonstrated to be from 100 to 500 % more efficient compared to applications of similar fertilizers to the soil. Foliar fertilizers are also more economical because smaller quantities of fertilizer are required to obtain significant plant response.

4. Enhanced carbohydrate production can either result in improved product quality or increased yields.

Plant nutrients within foliar fertilisers are rapidly absorbed by the plant leaves. Within 8 hours after the application of HuMates substances many different metabolic processes are detected. Enhanced carbohydrate production can be detected within 24 to 48 hours after foliar feeding by use of a refractometer. Enhanced carbohydrate production can either result in improved product quality or increased yields.

5.Foliar applications can be timed to meet the needs of specific plant growth requirements such as to activate vegetative growth, flowering, fruit set, or filling and ripening of fruits.

6.Energy metabolism is accelerated and the chlorophyll content of plant leaves is enhanced by the presence of humate substances.

When applied to plant leaves the chlorophyll content of those leaves increases and as the chlorophyll concentration increases there is a correlated increase in the uptake of oxygen.
