Ukuthatha Amasampula Enhlabathi
Ukuthatha amasampula enhlabathi yendawo okumele ihlonywe futhi lokhu kuhlaziywa yiyona ndawo ebaluleke kunazo zonke yokuqala kwanoma yiliphi ibhizinisi le-horticultural. Le nqubo ibonisa kokubili okuqukethwe komsoco okukhona emhlabathini kanye nokuthi yiziphi izakhi ezingenayo inhlabathi. Imiphumela yalezi zivivinyo izovumela ukuthi kube nezicelo eziningi zomanyolo wezinto zomanyolo we-macro ne-micro nutrient.
Indlela
Sebenzisa i-spade noma i-auger namabhakede amabili, ibhakede elilodwa ukuze ubeke phezulu kwesinye noma ngaphansi, ukuze uthole isampula esimeleyo kokubili phezulu kanye nezendlalelo zakho ezingaphansi. Isampula yama-topsoil ngokuvamile isuswa emhlabathini ophezulu ka-30 cm. Isampula encane isuswa kuphrofayili phakathi kuka-30 cm kuya ku-60 noma i-100 cm phansi, kuye ngokuthi isakhiwo sezitshalo uhlela ukutshala nokuthi uzimisele kangakanani ukulima inhlabathi. Uma isakhiwo sempande singajulile, kungase kudingeke ukuthi uthathe kuphela amasampuli endle. Ukuhlola iphrofayli kuya ezingeni elijulile kuzonikeza nomqondo ongcono womthamo wamanzi wenhlabathi yakho.
Udinga amasampula amane kuya ayisithupha ngehektare ngalinye.
Ucwaningo lokuqala olubonakalayo endaweni okumele itshalwe kuyo ukubona ukuthi kukhona yini ukuhluka okucacile (umehluko) esakhiweni somhlabathi. Uma kukhona ukuhluka okucacile, amasampuli kumele athathwe ngomhlabathi ngamunye. Uma inhlabathi ibukeka ibe yinto efanayo (iyafana), thatha amasampula kuwo wonke indawo yokutshala. Sula indawo yesampula yimuphi umcibisholo ongaphezulu noma utshani obunjengotshani nezinye izinto eziphilayo. Sebenzisa iphethini le-Z, S noma i-W endaweni yonkana yesampula. Kumelwe nje ukumboze indawo kanye nanoma yikuphi ukungafani okubonayo.
Ukusebenzisa Isanusi
Uma usebenzisa isanusi, thatha isampula esiphezulu se-30 cm bese uyisithelisa ebhakedeni elingaphezulu.
Phinda le nqubo ngomhlabathi ophansi kusuka ku-30 cm kuya ekujuleni oye wanquma futhi uchithe le nhlabathi ibe ibhakede elincane.
Phinda le nqubo kuzo zonke izisampuli ezitholiwe. Ngaso sonke isisindo esisodwa ebhaketheni elilodwa kanye nayo yonke indawo engaphansi kwesinye.
Ukusebenzisa Ifosholo
Uma usebenzisa ifosholo ukuqoqa amasampula kuqala ukumba imbobo lesikwele ngezinhlangothi ezibucayi ezihlanzekile ngokubonisa ngokucacile iphrofayli yomhlabathi phansi ekujuleni okufunayo. Thatha ihlumela bese uyiphakamisa phezulu kusuka ku-30 cm kuze kube sezingeni lomhlabathi womgodi ngaleyo ndlela uhlakaze ungqimba wamamitha amabili kuya kwamathathu ukusuka eceleni ukuze uqoqe kudofu. Lokhu kufakwe ebhakedeni eliphezulu.
Inqubo efanayo iyaphindwa ngokukhipha ifosholo phezulu ukuya phansi phansi emgodini kuya emasimini angu-30 ukuqinisekisa ukuthi ayikho insipho ekhishwayo ukuze inhlabathi yakho engaphansi ingcoliswe yisisindo sakho phezulu. Lokhu kubeka khona ibhakede elincane.
Phinda le nqubo kuzo zonke izisampuli ezitholiwe. Ngaso sonke isisindo esisodwa ebhaketheni elilodwa kanye nayo yonke indawo engaphansi kwesinye.
Uma wonke amasampuli ethathwe futhi zonke amasampula ezisemhlabeni amasayithi kanye namasampula angaphansi komhlaba asezinkalweni zawo ezifanele inhlabathi ibhakede ngalinye kufanele lixutshwe kahle.
Zonke amasampula akho angaphezulu ahlanganiswe ndawonye ebhakedeni elilodwa futhi wonke amasampula akho angaphansi ahlangene ndawonye kwenye.
I-laboratory ezokwenza ukuhlaziywa kwakho izokunikeza ubukhulu besampula abayidingayo ukuze lezi zingathathwa emabhakede bese zifakwa ezikhwameni zeplastiki zesampula futhi zikhonjiswe ngemininingwane yazo futhi zithunyelwe ngokushesha ngangokunokwenzeka kwisakhiwo sokucubungula.
