As a good fertilizer enhancer, sharply increase the utilization efficiency of potassium exists in plant itself and in soil, buffers nitrogen and improves nitrogen efficiency.
As a soil conditioner, promote good soil structure formation, increase the capacities of water holding and cation exchange and improve aeration condition.
Buffers phosphate to prevent fixation in the soil.
Promotes soil biology, especially fungal biomass.
Boosts the availability of iron, calcium and phosphate in the soil
As chelating and buffering agents, respectively helps retain water soluble inorganic fertilizers, preventing them from leaching, and protect plants from drastic change in PH.
3~5 kg/ha; or blend Potassium Humate with normal N.P.K
Dilute 0.2~8 kg Potassium Humate to average 100 liters water or other functional solutions. Apply 3~4 times, at intervals of 20 days during the growing season.
Add it to irrigation water with the ratio of 3~5 kg/ha
