Calcium Ammonium Nitrate (CAN)
Lemandou Calcium Ammonium Nitrate ndi gwero labwino kwambiri la calcium ndi nayitrogeni yomwe imapezeka msanga ku mbewu.
Calcium ndi michere yofunikira yayikulu yachiwiri, yolumikizana mwachindunji ndi kapangidwe ka khoma la mbewu. Popeza kusuntha kwa calcium m'mbewuyo kumakhala kochepa, kuyenera kuperekedwa nthawi yonse yakukula kuti misinkhu yazomera izikhala yolimba ndikuwonetsetsa kuti pakukula bwino. CAN imathandiza kuti mbewu zizitha kuthana ndi mavuto komanso zimapangitsa kuti mbewu zizikhala bwino.

Kashiamu Nitrate
Lemandou calcium nitrate ndi gwero labwino la calcium komanso nitrate nitrogen. Nitrate nayitrogeni ndiye gwero lokha la nayitrogeni lomwe limagwirizana ndi calcium ndipo limatha kulimbikitsa kuyamwa kwa calcium. Chifukwa chake, calcium nitrate imatha kuthandiza kubzala makoma am'magulu, potero kumapangitsa zipatso kukhala ndi zipatso.

Kashiamu Nitrate Granular + B
CN + B ndi 100% yosungunuka m'madzi ndipo ndi boron wokhala ndi calcium nitrate yosungunuka madzi. Boron imatha kulimbikitsa kuyamwa kwa calcium. Nthawi yomweyo, calcium ndi boron zimathandizidwa, mphamvu ya feteleza imathamanga ndipo magwiritsidwe ake ndi apamwamba. Ndi feteleza wosalowerera ndale, woyenera dothi losiyanasiyana. Ikhoza kusintha nthaka pH, kukonza dongosolo la nthaka, kuchepetsa kukanika kwa nthaka, ndi kuchepetsa kuipitsa nthaka. Mukamabzala mbewu zachuma, maluwa, zipatso, ndiwo zamasamba ndi mbewu zina, feterezayo imatha kutalikitsa nthawi yamaluwa, kulimbikitsa kukula kwa mizu, zimayambira, ndi masamba, kuwonetsetsa kuti chipatsocho ndi chowala, ndikuwonjezera shuga mumtengowo . Ikhoza kutalikitsa nthawi yogwirira ntchito yamasamba ndi nyengo yakukula kwa mbewu, ndikuchedwetsa kuchepa kwa mbewu. Ikhoza kukonza kulolerana kwa zipatso, kuwonjezera nthawi yosunga zipatso ndi ndiwo zamasamba, ndikupirira kusungidwa ndi mayendedwe.

Magnesium Nitrate
Lemandou Magnesium Nitrate imapereka magnesium ndi nayitrogeni mu mawonekedwe omwe amapezeka pazomera. Mankhwala a magnesium ndi ofunikira kuti mbewuzo zikule bwino. Ndipo nitrate imathandizira kutenga magnesium ndi chomeracho, ndikupangitsa kuti izigwira ntchito bwino. Zimapindulitsanso zakudya za mbewu zomwe zimapezeka mosavuta, nayitrogeni wosavuta.

Potaziyamu Nitrate
Lemandou potaziyamu nitrate (KNO₃) ndi feteleza wamchere wosungunuka m'madzi.
Potaziyamu ndiye chopatsa choyambirira chokhudzana ndi mtundu wa mbewu zonse, chomwe chimagwiritsidwa ntchito ngati feteleza wa mbewu zamtengo wapatali, chimathandizira kukonza kukula kwa zipatso, mawonekedwe, zakudya zopatsa thanzi, kununkhira komanso kumaonjezera mashelufu.
Kusungunuka kwa NOP ndichinthu chofunikira popangira madzi osungunuka a NPK.

Urea
Lemandou urea wokhala ndi nayitrogeni 46%, ndi mankhwala olimba a nayitrogeni. Manyowa a Urea amagwiritsidwa ntchito kwambiri muulimi. Ndiwo mtundu wofala kwambiri wa feteleza wa nayitrogeni womwe umagwiritsidwa ntchito padziko lonse lapansi. Amaonedwa kuti ndi gwero lazachuma la nayitrogeni. Wopangidwa kuchokera ku ammonia ndi kaboni dayokisaidi, uli ndi nayitrogeni wambiri kuposa feteleza wolimba wa nayitrogeni. Monga chogwirira ntchito, urea itha kugwiritsidwa ntchito mwachindunji m'nthaka pogwiritsa ntchito zida zofalikira. Kuphatikiza pa kugwiritsa ntchito nthaka, feteleza wa urea atha kugwiritsidwanso ntchito pakupanga feteleza kapena ngati foliar application. Komabe, feteleza wa urea sayenera kugwiritsidwa ntchito munthawi yocheperako, chifukwa urea imatuluka mchidebe nthawi yomweyo.
