ACI Fertilizer is working to develop an NPK-based Controlled Release Fertilizer for the soil and plant nutrition of Bangladesh. Controlled-release fertilizers (CRF) are a type of fertilizer that gradually release nutrients to plants over an extended period. These fertilizers are designed to provide a slow and steady supply of nutrients to plants, reducing the need for frequent application and ensuring optimal nutrient uptake by the plants. CRF work by incorporating a special coating around the fertilizer granules that control the release of nutrients. This coating can be made from a variety of materials, including sulfur, resin, or polymer, and can be designed to release nutrients based on factors such as temperature, moisture, or microbial activity in the soil. The main advantage of CRF is that they provide a more consistent and sustained supply of nutrients to the plants, which can improve crop yield and quality. They also reduce the risk of nutrient leaching into the environment, as the slow release of nutrients means that they are more likely to be taken up by plants before being washed away. There are several types of CRF available, including slow-release, controlled-release, and timed-release fertilizers. Slow-release fertilizers are designed to release nutrients over several months, while controlled-release fertilizers release nutrients over several weeks. Timed-release fertilizers release nutrients at specific intervals, such as every 30 or 60 days. CRF can be used in a variety of agricultural settings, including field crops, fruits and vegetables, turfgrass, and ornamental plants. They can also be used in hydroponic systems and as part of urban landscaping programs. While CRF can be more expensive than traditional fertilizers, their long-lasting effects can make them a cost-effective option in the long run. However, it is important to use CRF according to the manufacturer's instructions to avoid over-fertilization and potential environmental damage.
