Ziyintoni na?

I-nitrojeni njengomthombo wezityalo zondlo zivela ngokwemvelo emhlabeni, kodwa kwiindawo ezahlukeneyo zemozulu ukufumaneka komhlaba kuhlukile. I-nitrogen encinci emangalisayo emiphakeni yensihlabathi enesihlabathi kunye ne-sandy loamy. Ukongezelela, i-1% kuphela yale nkunkuma ifumaneka kwizityalo, ngoko kubaluleke kakhulu ukuphucula umhlaba ngomanyolo nge-nitrogen fertilizer, kwaye zeziphi izichumisi eziza kuxoxwa ngazo kweli nqaku.

Ukubaluleka kwe-nitrogen fertilizer kwizityalo

Isondlo esiphezulu se-nitrogen isondlo asinayo kuphela impembelelo entle kwizivuno, kodwa iphinda iphucule umgangatho wezityalo ezilima. Ngenxa yokunyusa ipesenteji yeprotheni kunye nokwandisa ukuxinwa kweeprotheyini ezixabisekileyo, izityalo ezilinywayo ziqala ukukhula ngokukhawuleza, amaqabunga awo abonakaliswe ngombala obomvu obumnyama, kwaye iziqhamo zikhulu ngokukhulu. Ukuba i-nitrogen ayaneleyo, ngoko kwicandelo elingenhla likhona i-chlorophyll kwaye amaqabunga akhula amancinane, alahlekelwa ngumbala, kwaye isivuno siwa. Masihlupheke kwintlupheko yeprotheni kunye nembewu. Ngoko ke, kubaluleke kakhulu ukudala izinto ezifunekayo ukwenzela ukuba uphuhliso oluqhelekileyo lwezityalo, ukubonelela umhlaba ngenani elifunekayo le-nitrogen.

Umquba we nitrogen

Ziquka:

1. Zonke iintlobo zomgquba, iintaka zeentaka, ngokukodwa idada, inkukhu nejuba.
2. Iifompo zomlo. Inani elincinci le-nitrogen liqulethwe kwimibhobho nakwimfucumfucu yasemakhaya.
3. Ubunzima obuhlaza. Kukho nakwimifanekiso, i-lake silt, i-lupine, i-clover e-sweet, i-vetch, i-clover, njl njl.

Umququzeleli wamaminerali weNitrogen

Abo bacela ukuba yiyiphi igama le-nitrogen fertilizer, kuyafaneleka ukubeka ingqalelo kuloluhlu:

1. Amakhunga ammonium yi-ammonium sulfate, i-ammonium chloride.
2. Iifomtri ze-nitrate zi-calcium kunye ne-nitrate ye-sodium.
3. Amide isichumisi yi- urea .

Oku kusebenza kwi-nitrogen fertilizer. Xa uthengiswa unako ukufumana nokuchumisa, uqukethe i-nitrogen ngexesha elinye kwi-nitrate ne-ammonia ifomu. Ukongezelela, kuyimfuneko ukwazi ukuba i-nitrogen fertilizer isetyenziselwa kunye ne-phosphorus kunye ne-potassium. Ezi zidingo zidibene ne-superphosphate, ithambo okanye i-dolomite, i-ammonium nitrate. Le ndlela yokugqibela isetyenziselwa kwiindawo ezibuthathaka ezinokuxinwa kwehlabathi. Ngokuqhelekileyo ixutywe kunye ne-superphosphate kunye negosa elithintekayo. Oku kuqwalasela uhlobo lwesityalo esilinywa, kuba iqondo kunye nendlela yokwenziwa kwe-nitrogen kuyo ihluke.

Kwizinga lezentengiselwano, kusetyenziswa i-nitrogen fertilizer egazini, ehanjiswa ngokulinganayo, ixutywe kakuhle kwaye isebenze ixesha elide. Nangona kunjalo, ukunikezelwa kwe-nitrojeni epheleleyo kwizityalo kunokuqinisekisa kuphela ukusetyenziswa kwezinto eziphilayo kunye nezichumisi zamaminerali.
