Polymer coated fertilizer, also known as controlled-release fertilizer, is a type of fertilizer that has a polymer coating surrounding the granules. The coating is designed to slowly release the nutrients in the fertilizer over an extended period, instead of releasing all at once. This improves the efficiency of nutrient delivery to the plants and reduces the frequency of application.
The polymer coating is made of a blend of natural and synthetic polymers, which helps to regulate the release of nutrients gradually. The slow release of nutrients reduces the risk of burning the plants due to the excessive application of fertilizers. It also ensures that the plants receive a consistent supply of nutrients over a more extended period compared to conventional fertilizers.
