Abstract

510,053. Fertilizers. AZOGENO SOC. ANON., and TONIOLO, C. Aug. 4, 1938, No. 23035. Convention date, Aug. 4. 1937. [Class 111] [Also in Group III] Alkaline earth or magnesium nitrates are crystallized to yield a granular fertilizer by spraying a supersaturated solution or supercooled melt thereof on to a continuously stirred layer of the same salts in powdered form, the said layer containing also nitrate or other compound of ammonia in solid form. Specifications 5586/10, 180,180 and 249,370, [all in Class 111], and French Specification 764,440 are referred to.
