Potassium Fulvate

fulvate-1

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
