METHOD TO OBTAIN COMPLEX N:K FERTILIZER Russian patent published in 2002 - IPC

Abstract RU 2182144 C1

FIELD: agriculture. SUBSTANCE: during the process to obtain ammonium nitrate out of ammonia and nitric acid at the stage of neutralization it is necessary to add potassium nitrate as 30- 70% solution at 2-20% weight against ammonium nitrate content. Then mixed solution is processed to obtain a ready-touse product by concentration and granulation due to the well-known technique. Complex fertilizer mentioned contains, weight%: N 34.2-30.4, K2O 0.9- 9.3. The fertilizer obtained contains no chlorine. EFFECT: improved quality and agrochemical value, increased parameters of technological process due to introduction of potassium nitrate. 3 cl, 1 dwg
