Chitsulo sulphate heptahydrate
Maonekedwe a sulphate wamphepete ndi wabuluu wobiriwira monoclinic crystal, motero amatchedwa "manyowa obiriwira" muulimi. Ferrous sulphate imagwiritsidwa ntchito kwambiri muulimi kusintha pH ya nthaka, kulimbikitsa mapangidwe a chlorophyll, komanso kupewa matenda achikasu omwe amayamba chifukwa chosowa chitsulo m'maluwa ndi mitengo. Ndi chinthu chofunikira kwambiri kwa maluwa ndi mitengo yokonda asidi, makamaka mitengo yachitsulo. Ferrous sulphate lili 19-20% chitsulo. Ndi feteleza wabwino wachitsulo, woyenera mbewu zokonda asidi, ndipo amatha kugwiritsidwa ntchito pafupipafupi popewa ndi kuchiza matenda achikaso. Iron ndiyofunikira pakupanga chlorophyll mu zomera. Chitsulo chikasowa, mapangidwe a chlorophyll amatsekedwa, ndikupangitsa mbewu kudwala chlorosis, ndipo masamba amasanduka achikasu. Njira yothetsera amadzimadzi ya ferrous sulphate imatha kupereka chitsulo chomwe chitha kuyamwa ndikugwiritsa ntchito zomera, ndipo chimatha kuchepetsa nthaka. Kugwiritsa ntchito sulphate wa feri, kunena zambiri, ngati dothi loumiralo limathiriridwa mwachindunji ndi yankho la 0.2% -0.5%, padzakhala zotulukapo zina, koma chifukwa chachitsulo chosungunuka m'nthaka yothiridwa, chitha kukonzedwa mankhwala osungunuka okhala ndi chitsulo Amalephera. Chifukwa chake, popewa kutayika kwa zinthu zachitsulo, 0.2-0.3% ya ferrous sulphate solution ingagwiritsidwe ntchito kupopera mbewu masambawo.
