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.

An organic fertilizer and an organic feed are produced by removing cadmium from processing residues of scallop (Patinopecten yessoensis) without separating the midgut gland. That is, a small amount of an aqueous citric acid solution is added to the processing residues of scallop including the midgut gland in which cadmium has been accumulated at a high concentration and the mixture of them is heated to 55 to 65° C. Thus, the thin midgut gland membrane is broken and the internal solution of the midgut gland containing cadmium is eluted. Then, solid matters are separated from the mixture including the solid matters and the internal solution of the midgut gland eluted. As the aqueous citric acid solution, a solution prepared by mixing at least 9% by weight of water relative to the processing residues and 1.8 to 3.3% by weight of citric acid relative to the total weight of the processing residues and water is used. The content of cadmium in the solid matters can be further reduced by adding water to the solid matters having been separated and then heating the mixture of them to 55 to 65° C., thereby washing off cadmium remaining in the solid matters.
