  • Nano-leucite for slow release nitrogen fertilizer and green environment
    Patent number: 8911526
    Abstract: To compete with the increasing global food demand, it is necessary to increase the food production. Fertilizers which are in practice now a days has major disadvantage that 50% of nutrient contents loss due to leaching and also leads to ground water contamination. Slow release nitrogenous fertilizers are good in this regard in that they have minimum nutrient loss due to leaching. Potassium aluminum silicate (Leucite) nanoparticles occluded by calcium ammonium nitrates are slow release fertilizers and are synthesized by hydrothermal method. Its application as slow released nitrates fertilizers was determined by observing nitrate release for 16 days.
    Type: Grant
