It appears as white crystals or powder, featuring complete water solubility, chlorine-free properties, and stable chemical characteristics, complying with the technical requirements for premium grade in the national standard GB/T 2321-2016 "Fertilizer-Grade Potassium Dihydrogen Phosphate."

II. Core Characteristics

High-purity nutrients: Product purity (KH₂PO₄ content) can usually reach over 99%, ensuring efficient nutrient utilization.

Full water solubility without residues: Dissolves quickly and completely, with a clear solution, suitable for foliar spraying and drip irrigation systems requiring strict water quality.

Safe, chlorine-free, and low sodium: Extremely low chloride ion content (≤ 0.2%) and strictly controlled sodium content, safe for chlorine-sensitive crops and salt-sensitive crops.

Acid-base buffering capacity: The pH value of a 1% aqueous solution is stable at 4.4-4.7, helping maintain fertilizer solution stability and regulate the rhizosphere microenvironment.

III. Main Applications

Agricultural field:

Efficient foliar topdressing: Suitable for fruit trees, vegetables, cash crops, and field crops during flowering, young fruit, expansion, and color change stages. It can quickly supplement phosphorus and potassium, playing roles in flower and fruit retention, promoting coloring, increasing sweetness, and enhancing stress resistance.

Water and fertilizer integration: An ideal raw material for high-end water-soluble fertilizers such as drip irrigation and sprinkler irrigation, without clogging pipelines.

Seed treatment: Used for seed soaking or dressing to improve germination rate and seedling resistance.

Industrial and special uses:

Used as a buffer and nutrient component in microbial culture media, biological fermentation, and chemical synthesis.

Food-grade products can be used as quality improvers in the food industry.

IV. Usage and Storage

Application methods: Recommended concentration for foliar spraying is 500-1000 times dilution; for drip irrigation, prepare mother liquor according to the crop's fertilizer requirement law. Avoid mixing with alkaline pesticides and fertilizers.Storage requirements: Seal and store in a cool, dry place, protected from moisture and caking.Quality verification: Request a quality inspection report when purchasing, focusing on checking nutrient content, purity, and impurity indicators.
