Superabsorbent Polymers for Agricultural Usage
Original language description
The aim of our research is to develop superabsorbent polymer based preparation which can be used as a delivery vehicle for the controlled-extended release of different types of fertilizers. A six series of polyacrylic acid gel derivatives has been prepared. NPK fertilizer was added as a main active ingredient. They differed in a content of lignohumate addition, acrylamide addition and in initial dosage of NPK. The mechanisms of phosphorus and potassium release from hydrogel carriers were observed together with their swelling properties. Both experiments were carried out together in an environment of demineralized water for five days. Concentration of K+ ions in surrounding water was determined by potentiometric measurements every 24 hours. Total content of potassium and phosphorus were determined by ICP ? OES technology also every day.
