Potassium Fulvate

Basic Product Introduction

Potassium Fulvate is a high-activity water-soluble fulvic acid salt refined from lignite/weathered coal. It contains low-molecular fulvic acid, active potassium, organic active groups, small peptides and trace bio-stimulating factors. Compared with potassium humate, its molecular weight is smaller, permeability and absorption speed are far stronger, with complete water solubility, no precipitation, strong anti-hard water performance. It can be used for seed soaking, root irrigation, drip irrigation, flushing and foliar spraying, applicable to all field crops, fruits, vegetables, cash crops, seedlings, Chinese medicinal herbs; feed-grade Potassium Fulvate can also be added to livestock and aquaculture feed.

2. Core Nutritional & Physicochemical Advantages

Ultra-small molecular weight, fast absorption by roots and leaves

Fulvic acid molecules are tiny, capable of quickly penetrating leaf cuticles and root cell membranes. Crops absorb nutrients within hours after application; works far faster than ordinary potassium humate.

Dual supply of organic carbon and fast-acting chelated potassium

Provides bioactive organic matter and chelated potassium simultaneously. Potassium wrapped by fulvic acid will not be fixed by soil clay particles, raising potassium utilization rate remarkably; improves soil fertility while supplementing potassium for crops.

Activate latent nutrients in soil, boost fertilizer efficiency

Its abundant carboxyl and phenolic hydroxyl groups chelate solidified phosphorus, potassium, calcium, magnesium, iron, zinc and other trace elements in soil, converting invalid mineral nutrients into absorbable ionic state. It improves the utilization rate of nitrogen, phosphorus and compound fertilizers by 20%–35%, reducing chemical fertilizer input.

Optimize soil aggregate structure, solve compaction, salinization and acidification

Promotes the formation of granular soil structure, loosens heavy clay soil; neutralizes excessive soil salt and acid, lowers surface salt accumulation in greenhouses and saline-alkali land. Enhances soil water & fertilizer retention capacity, reduces nutrient leaching loss.

Powerful rooting function, accelerate seedling recovery and repair damaged roots

Stimulates root tip meristem proliferation, generates massive capillary roots and fibrous roots within a short time. Ideal for seedling transplanting, grafting and post-disaster recovery; repairs rotten roots caused by fertilizer burn, pesticide phytotoxicity and continuous cropping obstacles, greatly improve seedling survival rate.
