Strong hydrophilicity and water retention capacity: Polyglutamic acid (γ-PGA) reduces soil infiltration rate, reduces water infiltration, increases soil saturated moisture content, reduces saturated hydraulic conductivity, and increases soil porosity. When submerged in the soil, a thin film will be formed on the surface of the plant root hairs. It not only protects the root hairs, but also serves as the best transport platform for nutrients, water and root hairs in the soil to come into close contact. It can effectively improve fertilizer production. dissolution, storage, transportation and absorption. Prevents the precipitation of sulfate, phosphate, oxalate and metal elements, allowing crops to more effectively absorb phosphorus, calcium, magnesium and trace elements in the soil. Promote the development of crop root systems and enhance disease resistance.
Balance soil pH: Polyglutamic acid (γ-PGA) has excellent buffering ability against acids and alkalis, and can effectively balance soil pH and avoid acidic soil caused by long-term use of chemical fertilizers. It plays the role of fertilizer conservation and inhibits the leaching of nitrate nitrogen and ammonium nitrogen to the deep soil.
Can combine and precipitate toxic heavy metals: Polyglutamic acid (γ-PGA) has excellent chelating effect on toxic heavy metals such as Pb+2, Cu+2, Cd+2, Cr+3, Al+3, As+4.
Enhance plant stress resistance: Polyglutamic acid (γ-PGA) by integrating plant nutrition and water-active components in the soil can enhance resistance to symptoms caused by soil-borne plant pathogens.
Promote increased yield: By maintaining soil moisture content and enhancing crop nutrient absorption, the effect of Polyglutamic acid (γ-PGA) in increasing crop yield can be achieved.
