The goal of this research is to investigate the leaching of phosphate glass fertilisers of various compositions under Soxhlet distillation settings. In the phosphate systems, glass fertilisers were melted at 900-950°C after soaking for 1 hour. Under Soxhlet distillation conditions with distilled water, a leaching investigation of these glasses was done for a maximum of 300 hours. BET surface area was used to assess weight loss and leach rates of glass fertiliser samples. measurements. They were in the range of 6.3x10-3 to 2.3x10-3 g.m-2.h-1 at 90°C. The effect of different modifier ions like Na+, Fe3+, Mg2+, Ca2+, and K+ in the basic phosphate networks on melting and time It has been discovered that there is a lot of melting going on. The pH of the leachate solution was measured at ambient temperature and revealed interesting and regular fluctuations ranging from 4.80 to 7.50. Ca2+, Mg2+, and K+ were found to be strong candidates as modifiers for quicker leaching in a Soxhlet analysis of such glasses. In terms of ionic size, ionic radius, and hence the ionic potential of the modifier ions absorbed into the glass structure, the findings were confirmed. Glass fertilisers were applied to kharif paddy. The presence of alkaline earth oxides enhances phosphate glass corrosion, whereas the addition of intermediate oxides lessens phosphate glass corrosion. The growth and production of khariff paddy were demonstrated to be better following the application of glass fertiliser than when traditional fertilisers were used.
