Potassium Fulvate is fulvic acid potassium salt, in powder form ,completely water soluble,with fulvic acid 10%min,humic acid 50%min,K2O 10%min.Usually be used for foliar spray or drip irrigation in agriculture.
Potassium fulvate contains potassium fulvates which are suitable for use directly as a foliar fertiliser or with other water-soluble NPK fertilisers as a chelating agent. K-fulvate chelates most plant nutrients and makes them readily available for uptake by plants through foliar applications in overhead irrigations or hydroponics systems. Scientific research has shown that the fulvic acids in K-fulvate boost the response time by plants to fertiliser applications. This is very important in correcting any nutrient deficiencies in plants during growth, especially where deficiencies in nitrogen or trace elements are concerned.
The fulvic acids in K-fulvate are extracted from the humic substances of naturally derived plant organic matter. Fulvic acids are distinguished by their golden brown colour as compared to the dark brown to black colour of humic acids.

As excellent foliar fertiliser carriers and activators. Their application in combination with trace elements and other plant nutrients, as foliar sprays, can improve the growth of plant foliage, roots, and fruits.
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 fertilisers to the soil. Foliar fertilizers are also more economical because smaller quantities of fertiliser are required to obtain significant plant response.
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.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.
