Soluble Poly Glutamic Acid Powder
polyglutamic acid≥3%, total N≥1%Insoluble matter≤0.5%, PGR, etc.
How it works:
1. Enrichment of nutrient, increase theutilization of fertilizer
It has the characteristics of anionic surfactant,i.e. it has
negative electric carboxyl on each residue of protein long
chain,which has outstanding chelation so that it’s ion exchange
adsorption is as 100times as natural soil in order to avoid
nutrient leaching, volatilization.
Itcan meet various needs of crops so as to greatly improve the
supplying abilityof soil nutrient when enriching Ca, Mg, Mo, Zn and
other micro-nutrient. Afterusing this product, It can improve
40~60% fertilizer-Nitrogen use efficiency(FNUE), more than 5.3% use
ratio of phosphate fertilizer, 10~20% use ratio ofpotash
fertilizer, meanwhile, it can save 20% fertilizer for per hectare,
andnutritional deficiency symptom can not occur easily.
2. Long duration ofeffectiveness and slow release functions
Low molecular weight PGA has thefunction of chelation and
adsorption to nutrient, so that it can store up thespare nutrient
that will be released slowly with crop growth so as to meetcrops’
needs for nutrient in middle and late period, to avoid premature
agingand insufficient in fertilizer, and reduce the top dressing
times and dressingapplication dosage. It can supply grain crops
enough base fertilizer to meet therequirement of nutrient for the
whole growing season, so as not to top dress,and thereby greatly
reduce the labor intensity.
3. Improve soil physical andchemical properties
The product itself is organic matter and it has functionto promote
root development and improve total recovery of organic matter
bysoil. After using this product, the content of organic matter is
improved 10% insoil, which improves the formation of soil granular
structure. This product ishighly absorbent so as to enhance the
crops capacity of drought-resistant andincrease 1.73~3.13% physical
clay content of the grain diameter between0.005~0.001mm and reduce
3.73% soil bulk density, make 0~20cm soil to increasewater content
1.5~2.8% and 20~40cm soil to increase water content 1~1.5%,thereby
to improve the crops drought resistance capacity. The increase
oforganic matter content and decrease of capacity greatly enhance
soil waterretention and nutrient preserving capability, and are
useful for cropsmetabolism and soil warm preservation in winter.
4. Strongly promote rootsystem development
This product contains auxin, cytomin and others usefulplant
hormones produced by micro-organisms so that it can effectively
promoteroot system development and increase in root surface area by
promoting to growlonger roots and more root hairs in order to
improve crops ability to absorbnutrients, and enhance crops
resistance to drought, cold, disease and so on, italso has ability
of anti-low temperature. This feature can greatly increase theyield
of earthnut and tuber crops, such as: potato, sweet potato, fresh
ginger,garlic, onion, radish, peanut and so on.
5、Improve the crops yield andquality
It is a necessary nutrient to crops, and can promote the
proteinsynthesis by supplying coordination the plants nutrient,
make the crops earlymaturity and promote products quality, so that
it avoids crops bring deformityfruit, and dehiscent fruit and poor
fruit color caused by malnutrition and useof hormone. Using this
product, corn protein content can increase 3%~6%; wheatproteins
content can increase 20% ~ 30%; tomato soluble sugar content
canincrease 0.5% ~ 1%, crude protein can increase 0.1%, fruits
sugar content canincrease 10%~20%, and first-level fruit can
increase, watermelon can increase8~10% sugar content; grapes sugar
content can increase 10%, first level tobaccocan increase 13% and
middle grade tobacco increase 6% among the tobacco.
After use of this product, grain crops yield can increase10~15%,
vegetable can increase 30~60%, solanum vegetable can increase
10~15%,pasture grass can increase about 30%, oil crops increase
The product itself is nutrient and non-toxic sideeffects,
degradation products in the soil are not residual toxicity.
Application Scopes: leafy vegetables, grain crops, cashcrops, lawns, flowers, etc.
1. As basal-dressing and top-dressing, it can be equallymixed with
