Slow-release fertilizers

Why are slow-released fertilizers useful? Because they make nutrients available for plants gradually over time, tuning plants needs and nutrients uptake.

Fertilizers can be considered as innovative, and rewarding for the farmers, when their performance enhances the lawn, reduces fertilization costs and has very low impact on the Environment. Green Ravenna designed its portfolio of granular fertilizers basing on the above-mentioned fundamental points: Nitrogen fertilizers, able to release gradually the nutrient over time, as Nitrogen is the most important element for turf look and performance, as well as the most probable subject to leaching in soil.

Green Ravenna Slow-release granular fertilizers are manufactured with a specific technology that enables to cover nutrients with polymeric resins, the only ones able to grant specific release timings. Green Ravenna fertilizers are based on the MCT - Multicotech technology: high purity nutrients are covered by a special biodegradable polymeric membrane based on organic resins that will completely degrade once Nitrogen release is over. This membrane regulates nutrients release only according to the average soil temperature, and it is not influenced by soil type, pH or the microbial community. The water in the soil vehiculates nutrients toward roots, without any negative effects on the release speed: it allows to have the perfect synchrony between plants needs and nutrients release. At low temperatures (< 5°C), nutrients release is approximately zero, even with high soil humidity, avoiding useless nutrients waste in the Environment.

Green Ravenna fertilizers advantages:

• Balanced turf growth thanks to nutrients release in function of plants needs.
• Reduction in loss due to volatilization and leaching.
• Reduction in dangerous salt excess.
• Reduction in fertilizers rates and consequent cost reduction for farmers.
