Sorption characteristics of nano zeolite based slow release sulphur fertilizer

Understanding the sorption process in natural zeolites is necessary for effective utilization of these minerals as nutrient adsorbents and consequently as controlled releases of plant nutrients. This research was undertaken to characterize the ability of natural zeolites minerals to adsorb and release sulphur. The potential for sorption of these ions were evaluated by applying the Langmuir equations. Thus a percolation reactor experimental setup was used to study the sorption, desorption pattern of nutrients. The nano-zeolite has been fortified with a sulphur source (Gypsum). Nano-fertilizer formulation is capable of releasing nutrients to the tune of 1000-1200 hrs while conventional fertilizer could release only up to 300-350 hrs. The data suggested that nano-formulation will be very ideal to regulate release of nutrients. This project is one of the pioneering attempts to synthesis zeolite based fertilizer formulation to regulate the nutrient release.
