Abstract

Unstable chemical fertilizers, such as ammonium bicarbonate, are preserved in granular form by subliming on to them a more stable substance, preferably also a fertilizer, such as ammonium chloride or sulphate, or urea. With urea, the sublimation is performed in vacuo.ALSO:Unstable chemical fertilizers, such as ammonium bicarbonate, are preserved in granular form by subliming on to them a more stable substance, preferably also a fertilizer, such as ammonium chloride or sulphate, or urea.
