Potassium Fulvate is one of the major components of humic substances.It is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner.
Chemically, potassium fulvate is a super-molecular heterogeneous aromatic hydroxy carboxylic acid composed by various functional groups, taking on effects of sorption, complexation, chelation, flocculation, which dissolves loads of hydrophobic matters.
Function & Benefits:
- Enhancing nutrient uptake by combining nutrients and humic aid as well as keep a well-balanced nutrition.
- Improving the structure of soil, increase the buffering powder of soil, optimize N. P. K absorption by plants.
- Increasing capacities of water holding and cation exchange
- Reducing nitrate leaking into the groundwater and protect the underground water
- Enhancing the resilience of crops, such as cold, drought, pest, disease and toppling resistance
- Stabilizing nitrogen and improve nitrogen efficiency (as an additive with urea)
- Promoting healthier, stronger plants and beautify appearance
- Enhancing soil ability of anti-hard water
- Detoxifying pesticide residues on the edible seed or fruits
Application:
- 1. Used as multi-functional compound fertilizer, combined with Nitrogen and Phosphorus, Mainly used as basal fertilizer, top dressing, seed fertilizer and foliar fertilizer
- 2. Foliar spray: 5-8kgs per ha/time, 2-3 times during seeding and growth stage
