CRFs, which have been used since the 1960s, are the main purpose of fertilizer use, to increase yield and to produce products suitable for the market. CRFs are granular fertilizers that release nutrients (macro-micro elements) under certain conditions for a certain period of time and are covered with a semi-permeable material.
How do CRFs work?
Controlled Release Fertilizers (CRFs) are covered with a semi-permeable material, allowing the release of nutrients in the soil along with moisture. In addition to moisture, soil temperature is another factor affecting the release.
As nutrient losses are minimized, the risk of salinity is minimized with a balanced fertilization.
• Less nutrient loss = higher nutrient efficiency
• Continuous and balanced feeding = higher or equal yield
• Fewer applications = less cost
• Environmentally friendly
• protection against “salt stress”
Our technological difference
• All NPK and trace elements are protected
• The release of nutrients depends on temperature, humidity and microbial activity.
• Faster release at high temperatures, Less release at low temperatures
• Losses due to gas, leakage or other means are at minimum level.
