Hangata e behiloe sebakeng se lefifi, leka ho fokotsa palo le nako ea ho buloa ha tanka ho fokotsa tšebeliso ea metsi a naetrojene. Kamehla eketsa metsi a naetrojene ho netefatsa hore bonyane karolo e le 'ngoe ho tse tharo ea metsi a naetrojene e bolokiloe ka tanka. Nakong ea polokelo, haeba tšebeliso e kholo ea metsi a naetrojene kapa serame se tsoang ka ntle ho tanka e fumanoa, ho bontša hore ts'ebetso ea tanka ea metsi ea naetrojene e sa tloaeleha 'me e lokela ho nkeloa sebaka hang-hang.

2. Litlhokomelo tsa ho boloka peō ea likhomo tse hatselitsoeng ka tankeng ea metsi ea naetrojene ke efe? Theknoloji ea ntlafatso ea peō e hatselitsoeng ea likhomo hajoale ke theknoloji e sebelisoang haholo le e sebetsang hantle ea ho ikatisa. Paballo e nepahetseng le ts'ebeliso ea peo e hatselitsoeng ke e 'ngoe ea lintho tse hlokahalang ho netefatsa kemolo e tloaelehileng ea likhomo. Ha ho bolokoa le ho sebelisa peo ea likhomo e hatselitsoeng, tlhokomelo e lokela ho lefshoa ho: peo e hatselitsoeng ea likhomo e lokela ho bolokoa ka litankang tsa metsi tsa nitrogen, le motho ea inehetseng ea ikarabellang bakeng sa tlhokomelo. Naetrojene ya metsi e lokela ho ekeletswa ka dinako tse tlwaelehileng beke le beke, mme boemo ba ditanka tsa nitrogen tse metsi di lokela ho hlahlojwa kgafetsa.
