PCU contains higher nitrogen 43%-45%, polymer technical help control the nitrogen release time from 30 days to 180 days, reduce nitrogen leaching and improve the uptake efficiency to save cost and labor, reduce the top dressing times and improve yield.
PCU is a perfect fertilizer to replace the traditional 46% Urea to help farms improve yield.
一，Product advantages:
■High particle uniformity
A unique screening system is adopted to screen the large-particle urea for a second time, and only the particles between 2.0-4.75mm are retained. The particle uniformity is high and the controlled release effect is more stable.
■Can do anti-floating treatment
The products used in paddy fields can be treated with anti-floating treatment, and the efficient and environmentally-friendly anti-floating technology can reduce the floating rate of fertilizer from 15% to 0%.
■Longer controlled release period
Generally, the controlled release period of resin-coated urea products is 2 months. By adjusting the film material formula, the controlled release period can be extended to 3-6 months under the same coating rate.
二，General features of the product:
■Degradable high-tech coating materials, continuously controlled supply of Nitrogen
The 5th generation coating is easily degradable and high-tech, special nitrogen-regular mode, providing a continuous and controlled supply of nitrogen with typical “S” release curve. Nitrogen slow release characteristics fit for target crops in different growth stages
■Higher nitrogen content, longer release period
Ultr-thin film materials produce high-content resin-coated urea, which is suitable for formula fertilizer production. The release period is longer, and the release speed is consistent with the law of crop fertilizer requirements to meet the nutritional needs of crops throughout the season. There is no burning of seedlings in the early stage and no fertilizer removal in the later stage.
■Economic and efficient, saving labor and time
Fertilization is applied once during the growing season to meet the nutrients of the crop throughout the season, reduce the frequency of fertilization, and save labor, time and fertilization costs.
■Environmental friendly, safe to use
The production process of the product is solvent-free, non-toxic, non-waste, non-polluting, and non-emission; reducing the amount of fertilizer in the use link can reduce the loss of nitrogen, is not easy to volatilize, leaching, reduce the accumulation of nitrogen in the soil, and reduce its salinization Degree, energy saving and energy saving
1. Production materials:
Need at high temperature, the resin raw materials (vegetable oil polyurethane) evenly wrapped in the table of large particles of urea, to achieve a real controlled release effect of nitrogen fertilizer particles!
2. Is it environmentally friendly?
Can be degraded in the soil, completely natural degradation, will not cause secondary pollution to the soil
3. Release method:
The use of soil temperature and water vapor pressure difference inside and outside the film to achieve the release effect, truly achieve the slow release effect of nitrogen fertilizer, is the current controlled release fertilizer industry effect is better production process! The controlled release effect can reach 60 days, 90 days and up to 120 days, truly realizing the effective use of nitrogen fertilizer, ensuring that there is no shortage of fertilizer in the whole growth of crops, and making the utilization rate of nitrogen fertilizer reach a new height
