Ethetha ngengozi yokungcola kwemveliso yokutya ne-nitrate, okokuqala sifanele sitsho malunga nenani lezityalo ezisetyenzisiweyo kunye neemeko phantsi kokuba izityalo zikhulile kwaye ziphi umhlaba owakhula. Kwimeko apho ngexesha lokukhula kakhulu kwakukho ukulahleka kwelanga kunye nokushisa, i-nitrate ayinakho ukuguqulwa ibe ngamaprotheni , ngenxa yoko ukugqithiswa kwabo ngokugqithiseleyo kwisityalo kubonwa. Ukuthetha malunga nomxholo we-nitrate ekudleni, kufuneka kuthiwa yingozi kakhulu yileyo ekhulile kwizimo ze-hothouse. Kodwa isona sizathu esona sizathu sokuthi abantu abanetyhefu bangabizwa ngokugqithiseleyo kwemali yezichumiso kwizityalo ezingabangela iziphumo ezimbi kumzimba.
Nitrates ekudleni
Ukuthetha malunga ne-nitrate ekudleni, kufuneka kuboniswe ukuba iziqhamo ezikhulile kwizichumisi ezibonakalayo kwaye zibonakaliswa ngokuba khona kwenani elikhulu le-nitrate ziyaziwa ngokugqithiseleyo ngobukhulu obukhulu obungabonakaliyo, ubuninzi kunye nokuquketwa kwamanzi aphezulu. Kule meko, amaqabunga ngokwabo angaba nombala oqaqambileyo. Ngamanye amaxesha, iimveliso eziqukethe i-nitrate zikhula ngokukhawuleza kangangokuthi ziyaqala "ukupasa kwiindawo zokuhlala".
Kubaluleke kakhulu ukujonga umntwana esecaleni. Ukuba iqukethe inani elikhulu le-nitrates, ngoko-ke ukusika kwayo kungahluka kwiindawo ezingezizo zendalo kunye nombala ongalinganiyo, kwaye unobumba obumnyama, u-veining, condensation, obonisa ubukho be-nitrate enkulu kwisiqhamo. Kule meko, iimveliso eziqulethe kuzo zininzi zihluke kwelinye intsingiselo. Ngoko, umzekelo, ukuba unomlinganiselo owongezelelweyo we-nitrates, ukunambitheka kwabo kuya kuba nzima kakhulu - kukho ukunambitheka okungokwemvelo kwesiqhamo, kuba nzima ukugwinya kunye nokuhlafuna, nangona kubonakala ukuba imveliso enjalo ingaba mnandi kakhulu.
