Controlled-release fertilizers are specially formulated products that release nutrients gradually over time. This slow release allows plants to absorb the nutrients more efficiently, reducing the risk of nutrient leaching and minimizing environmental impact. These fertilizers are often coated with materials that regulate the release rate based on temperature, moisture, or microbial activity in the soil. By using controlled-release fertilizers, gardeners and farmers can improve crop yields and promote healthier plant growth. This method also helps in reducing the frequency of applications, saving time and labor. Overall, controlled-release fertilizers contribute to more sustainable agricultural practices and better resource management.
