YM NANO SILICA

Agriculture and Silicon Fertilizer Industry

Silicon is recognized as a beneficial element for plant growth. Silica sol, due to its nanoscale size, high dispersibility, and high reactivity, has been developed as a novel foliar silicon fertilizer, primarily used for heavy metal pollution remediation and enhancing crop resistance.

1. Heavy Metal Pollution Remediation/Passivation Agent (Follicular Barrier)

• Common Types: Alkaline or neutral (pH 7-10), high purity, low sodium/ammonium stabilizer (requires removal of heavy metal impurities).

• Silicon Content: 10% - 30% (appropriate dilution is required for foliar spraying, commonly 20%-25%).

• Particle Size: 10-40 nm (nanoscale small particle size to facilitate passage through leaf stomata).

• Function and Principle:

• Physical Barrier: After spraying, a silicified layer (similar to a "coating") forms on the leaf surface, enhancing leaf mechanical strength and disease resistance.

• Physiological Blocking: After being absorbed by crops, it can precipitate or complex toxic heavy metal ions (such as Cd, Pb, Cr, As, etc.) within the plant, inhibiting their translocation and accumulation from the roots to the above-ground parts (seeds/fruits), thereby reducing the heavy metal content in agricultural products.

• Nitrate Resistance: When combined with molybdenum, it can significantly inhibit the absorption and accumulation of nitrates in vegetables.

2. Functional Compound Silicon Fertilizer (Nutritional/Conditioning Type)

• Common Types: Acidic or alkaline (depending on the compatibility of elements), may contain functional ions (such as molybdenum, rare earth elements).

• Silicon Content: 10% - 25% (compound fertilizer formula).

• Particle Size: 10-30 nm.

• Function and Principle:

• Synergistic Effect: Utilizing the dispersibility and adhesiveness of silica sol, it loads trace elements (such as molybdenum, zinc) or rare earth elements, resulting in good adhesion after spraying and resistance to rain washout.

• Supplementing Silicon Nutrients: Providing highly active silicon nutrition for silicon-loving crops such as rice (rice is a typical silicon-loving crop, as silicon can improve its resistance to lodging and pests).

• Slow-Release Carrier: Utilizing its gel properties, it forms a slow-release layer on the leaf surface, prolonging the fertilizer's effect.
