Ferrous sulphate heptahydrate
Muuqaalka sulfate ferrous waa buluug-cagaaran monoclinic crystal, sidaa darteed guud ahaan waxaa loogu yeeraa "digada cagaaran" beeraha. Ferrous sulfate waxaa badanaa loo isticmaalaa beeraha si loo hagaajiyo pH ee ciidda, kor u qaadista sameynta chlorophyll, iyo ka hortagga cudurka huruuda oo ay keento bir yaraanta ubaxa iyo geedaha. Waa cunsur aan looga maarmin ubaxyada iyo dhirta aashitada jecel, gaar ahaan geedaha birta ah. Ferrous sulfate waxay ka kooban tahay 19-20% bir. Waa bacrimin bir ah oo wanaagsan, oo ku habboon dhirta aashitada jecel, waxaana loo isticmaali karaa si joogto ah si looga hortago loona daweeyo cudurka huruudda ah. Birta ayaa lagama maarmaan u ah sameynta chlorophyll ee dhirta. Marka birta ay yaraato, sameynta chlorophyll waa la xannibaa, taasoo keenta in dhirta ay ku dhacdo chlorosis, caleemihiisuna ay isu beddelaan huruud cirro leh. Xalka aqueous of ferrous sulfate wuxuu si toos ah u bixin karaa birta nuugi karta ugana faa'iideysan karta dhirta, waxayna yareyn kartaa alkalinka carrada. Codsiga sulfate ferrous, guud ahaan hadlida, haddii carrada dheriga si toos ah loogu waraabiyo xal ah 0.2% -0.5%, waxaa jiri doona saameyn gaar ah, laakiin birta ku milmay carrada ku shubmay awgeed, waxaa si dhakhso leh loogu hagaajin doonaa macdanta birta ku jirta ee aan milmi karin Sidaa darteed, si looga fogaado luminta walxaha birta, 0.2-0.3% xallinta maadada milix leh ayaa loo isticmaali karaa in lagu buufiyo dhirta caleenta.
