Beschreibung
Zusammenfassung:	FIELD: mixed fertilizers. ^ SUBSTANCE: invention relates to manufacture of phosphorus-containing fertilizers, in particular to organo-phosphoro-zeolite fertilizer manufacture. Process comprises simultaneously breaking and mixing natural phosphate material, brown coal, zeolite, and additives of mineral acids or acid salts at weight ratio 1:2:0.5:(0.02-0.08), respectively. ^ EFFECT: simplified process and improved quality of organo-phosphoro-zeolite fertilizer due to increased portion of citric acid-soluble form of phosphoric anhydride. ^ 2 tbl, 2 ex
