zeolite as a nitrogen reservoir

Zeolite and urea = more nitrogen in the soil + increased yield: this is the experimental result of an interesting study by three scientists from Malaysia. The study was carried out at Universiti Putra by Omar Latifah, Osumanu Haruna Ahmeda and Nik Muhamad Abdul Majid in collaboration with the Malaysian Ministry of Higher Education. The experiment Zeolite and urea = more nitrogen in the soil + increased yield The high cost of nitrogen fertilisers leads to practices aimed at optimising their use, whilst minimising nitrate losses. Ammonium adsorption inhibits the loss of nitrogen in the form of nitrate, thereby increasing ... Read more

Frederick A. Mumpton, Department of Earth Sciences, State University College, Brockport, NY 14420 Introduction As agriculturalists around the world step up their efforts to expand crop and livestock production, increasing attention is being paid to various mineral materials as soil amendments and as dietary supplements in animal husbandry. The close relationship between the agricultural and geological sciences is not new—crop production depends on the existence and maintenance of fertile soil, and agronomists rely on knowledge of the mineralogy and geochemistry of clays and other soil constituents. In animal sciences, the addition of crushed limestone to chicken feed to strengthen eggshells ... Read more
