chemical fertilizer with slow and controlled releases are made to release nutrients gradually over an extended period of time to meet the needs of crops. They decrease the risk of overfertilization, decrease nutrient losses due to leaching and volatilization, and increase the effectiveness of nutrient utilization.
Fertilizers that have been coated: Coating technologies have been developed to improve the characteristics of fertilizers’ nutrient delivery. A protective layer on coated chemical fertilizer regulates the rate at which nutrients are released. The coating may be programmed to release nutrients in response to conditions like temperature, moisture content, microbial activity, or predetermined time periods. This technique aids in the controlled release of nutrients, lowers nutrient losses, and enhances crop nutrient uptake.
Enhancing the availability and effectiveness of nutrients for plants is the goal of enhanced efficiency fertilizers (EEFs). Products like nitrification inhibitors, urease inhibitors, and phosphorus enhancers can be included in them. Nitrification inhibitors reduce nitrogen losses by leaching and denitrification by slowing the conversion of ammonium to nitrate. Urease inhibitors reduce nitrogen volatilization by delaying the breakdown of urea. By lowering its fixation in the soil, phosphorus enhancers increase the availability of phosphorus to plants.
Precision Agriculture Technologies: Farmers can acquire specific information about soil variability, crop development, and fertilizer requirements using precision agriculture instruments including remote sensing, GPS, and yield mapping. With the use of these technologies, farmers may more precisely decide how much and where to apply fertilizer, ensuring that the proper amount is applied at the right time.
