I-straw isetyenziswe njengesichumisi kwizityalo ngaphezu kweminyaka elishumi. Kwaye oku kuchanekileyo ngokuqinisekileyo ukuba iqulethe izinto ezininzi kunye nezixhobo ezincedo.
Ukusetyenziswa kotshani njengesichumisi somyezo
Xa ama-5-6 amathani omhlaba awela emhlabathini, umququ unokuwucebisa nge-30 kg ye-nitrogen, i-6 kg ye-phosphorus, i-80 kg ye potassium, i-15 kg ye-calcium kunye ne-5 kg ye-magnesium. Vumelana, ezi zibalo ziyamangalisa. Kakade, iimeko ezithile kufuneka zidibeneyo ukuzalisa umhlaba ngala mazwi.
Okokuqala, utshani kufuneka luhlale emhlabathini emva kokulima okungenani iinyanga ezili-8. Kuphela emva kwexesha ungatshala izityalo ezintsha apha. Inyaniso kukuba i-straw efana nesichumisi incedo kwiimeko ezilahlekileyo. Xa sele ufikelele kuyo, ivelisa i-humus, eyenza iipropati ezixabisekileyo zomhlaba. Ukukhawulezisa ukubola kwe-straw, i-nitrogen yamaminerali iphinda ifakwe emhlabathini.
Ukongezelela, utshani obuncitshisiweyo njengesiqhumiso ngumthombo ogqwesileyo we-carbon dioxide, ochaphazela ukuphuculwa kweemeko zokutya zomoya zityalo. I-straw iphucula isakhiwo somhlaba kwaye ikhusela umhlaba ekukhuliseni, kwaye ivuselela iinkqubo zamandla emhlabeni.
Ukusetyenziswa komnxeba njenge-mulch kunye nesichumiso kuqhelekileyo phakathi kwabagadi bamaninzi ukwenzela ukunciphisa ukukhula kokhula. Kule meko, i-mulch yomdaka ekwindla inceda gqitha ukuphosa emhlabathini, ukwenzela ukuba entwasahlobo, ukwandise umkhiqizo womhlaba kunye nokuphucula umthamo wokuxhamla kwendawo egciniweyo yomhlaba.
Yiyiphi intlobo efanelekileyo yokuchumisa umhlaba?
Ukutshala umhlaba, utyani lwezityalo kunye nezityalo ezifanelekileyo zifanelekile. Kule meko, izitshalo ezomileyo zezityalo kufuneka zibe nesakhiwo se-tubular esincinci kunye nombala ophuzi okanye obomvu ngaphandle kokunyanzeliswa okuluhlaza kunye nokukhula kwefungal.
I-straw ye-legumes iyafa ngokukhawuleza kwaye iqulethe ubuncinci bezilwanyana ezinambuzane kunye neentshuluzane, ezibalulekileyo ekufumaneni umphumo omuhle ngokubhekiselele kumhlaba ngaphandle kokulimaza.
