Controlled-release fertilizers can help address the challenge of feeding the growing population with limited arable lands.
A smart fertilizer
Typically, during fertilization with urea losses of valuable nutrients like nitrogen or CO2 are observed, as plants cannot take up all nutrients supplied at once. In order to feed the growing world population and limit the environmental impact, more efficient and sustainable fertilizers are needed.
Our smart fertilizer design provides the required nutrients at the right time and the right rate, resulting in more efficient use of nutrients. This smart innovation helps farmers improve their yields and optimize their production.
Traditional fertilizer vs. controlled-release fertilizer
How controlled-release fertilizer works
The smart fertilizer has a polymer coating that contains the nutrients inside the membrane. It prevents valuable nutrients from leaching into the soil and volatilizing into the air.
The coating provides a semi-permeable membrane around the fertilizer. Due to the fertilizer's hygroscopic nature, water will permeate through the membrane, allowing the nutrients to dissolve.
The low nutrient concentration outside the membrane will act as a driving force to permeate dissolved nutrients through the membrane into the soil. This process is mainly controlled by temperature and thus synchronized with the growing process of the plant, leading to extremely effective nutrient uptake.
