POLYMER-COATED CONTROLLED-RELEASE FERTILIZER (CRF) TECHNOLOGY
Ultra-thin polymer coating system engineered to release nutrients in response to soil temperature, aligning precisely with crop uptake curves over 30 to 540 days.
TECHNOLOGY OVERVIEW
Kingenta's proprietary Polymer-Coated Controlled-Release Fertilizer (CRF) Technology encapsulates high-analysis NPK, Urea, and specialty nutrient granules inside an elastomeric polymer membrane. Engineered to release nutrients gradually based on soil temperature, it eliminates the risk of nutrient leaching, volatilization, and seedling root burn.
TEMPERATURE-SYNCHRONIZED NUTRIENT DELIVERY
Conventional soluble fertilizers release their entire nutrient payload immediately upon contact with soil moisture, causing severe leaching into groundwater and atmospheric nitrogen volatilization. Kingenta's polymer-coated technology solves this inefficiency by creating a semi-permeable membrane barrier.
The rate of nutrient diffusion across the polymer shell is governed solely by soil temperature—the same primary driver of crop metabolic rate. As the soil warms and crop growth accelerates, nutrient release increases proportionally, ensuring continuous, optimal plant nutrition throughout the entire growing season.
4-STEP CONTROLLED-RELEASE MECHANISM
How the elastomeric polymer membrane regulates nutrient release over extended crop cycles.
Encapsulation
High-purity nutrient granules (NPK, Urea, MAP, or Potassium Nitrate) are uniformly coated with a precise, ultra-thin polymer membrane layer.
Water Absorption
Soil moisture penetrates through the micro-porous polymer membrane via osmotic vapor diffusion, entering the granule core.
Nutrient Dissolution
Solid nutrients inside the core dissolve into a concentrated liquid solution beneath the elastic, pressure-resilient polymer shell.
Controlled Diffusion
Dissolved nutrients diffuse outward through the membrane into the root zone at a rate controlled by soil temperature over 1 to 18 months.
WHAT CRF TECHNOLOGY PROVIDES TO CROPS
Key agronomic and environmental advantages engineered for modern sustainable agriculture.
Up to 60% Reduction in Environmental Losses
Prevents nitrate leaching into groundwater and minimizes ammonia volatilization and nitrous oxide emissions.
Single-Application Season-Long Nutrition
One single basal application supplies complete crop nutrition for 30 to 540 days, eliminating side-dressing labor and fuel costs.
Soil Temperature Synchronization
Release rate automatically speeds up in warm soil during active plant growth and slows down in cool soil.
Zero Seed & Root Burning
Low salt index prevents high localized ion concentration, allowing safe precision placement near seeds and young roots.
High Nutrient Use Efficiency (NUE)
Dramatically increases nitrogen, phosphorus, and potassium absorption rates per unit of applied fertilizer.
Customizable Release Profiles
Formulated with tailored longevities for arable crops (3–4M), vegetables (5–6M), plantations (9–12M), and turf (up to 18M).
