Potassium humate is a kind of non-homogeneous aromatic hydroxycarboxylate with black appearance, powder shape, particle or flake solid, soluble in water, alkaline, containing hydroxyl, carboxylate and other active groups.It is a kind of highly effective organic potassium fertilizer, because humic acid is a kind of biological active preparation, which can improve the content of rapidly available potassium in soil, reduce the loss and fixation of potassium, and increase the absorption and utilization rate of potassium in crops.In addition, potassium humate can also be used as a treatment agent for oil drilling fluids, mainly to prevent borehole wall collapse.
Foliar spray: 1: 3000 dilution, apply 3-4 times during full season;
Soil irrigation: 1.5-2.0kg, by water flooding irrigation or drip irrigation;
Seeds soaking: 1:3000-5000, the time of soak is determined according to the thickness of seed skin. In general, it should be soaked 5-8h.
The suggested the rate is approximate and may vary depending on the climatic region, soil type, and fertility.
Directions For Use:
Turf Fertigation Injection: The preferred application method is to applyCalcium Thiosulfate in the irrigation water at 30 - 40 oz. per 1,000 sq. ft. (10 - 13.5 gallons per Acre). Apply as needed during the growing season as indicated by soil and tissue testing. Apply Calcium Thiosulfate in the middle 1/3 of the irrigation set.
Soil Spray Application for Greens, Tees, Fairways, Roughs, Sports Turf & Lawns: Apply 6.0 - 12.0 oz. ofCalcium Thiosulfate with 1.5 - 2 gallons of water per 1,000 sq. ft. (2.0 - 4.0 gallons of Calcium Thiosulfatewith 66 - 88 gallons of water per Acre). Apply every 14 days throughout the growing season. Irrigate immediately after application to knock concentration off leaf blades to prevent injury and into the soil profile to correct sulfur and calcium deficiencies.
It is not recommended to apply foliar applications of Calcium Thiosulfate on turf without irrigation due to the possibility of burn after application. (Foliar application is defined as a spray application that is NOT irrigated into the soil). Do not apply to turf when temperatures are above 90°F. Apply Calcium Thiosulfatein the early morning or late evening.
