Ekupheleni kwehlobo, izakhamuzi zasehlobo zivuna ukuvuna, ziqede isizini ziphelile, futhi zibeke phansi izimo zonyaka ozayo wokuvuna zibe ngcono njengeyaphambilini, futhi zingcono nakakhulu. Futhi zonke izikhula ezikhulayo kusayithi, zisadingeka ukunakekelwa nokukhathazeka ngokucophelela, ngoba okungaphezu kwesisodwa kuzodingeka zikujabulise ngokubuyisela ngesimo sezithelo ezimnandi nemifino esisha.
Akubona bonke abalimi abahlelwa yihlabathi elithambile elithambile. Uma isayithi liseduze nehlathi, ama-horse sorrel, ama-fern namahlathi amaningi ehlathini akhula ngokugcwele kuwo, ngakho-ke kungaphetha ngokuthi inhlabathi lapha ibonakala nge-acidity ephakeme. Ngaphandle kokuthatha izinyathelo ezifanele ukucubungula inhlabathi, ubeka ingozi yokulahlekelwa isitshalo owawubala. Ama-strawberries, utamatisi, iklabishi kanye namakhukhamba enhlabathini nge-asidi ephezulu ayakhuli njengoba ungathanda.
Indlela yokubhekana ne-acidity yenhlabathi?
Ukuze ungcolise inhlabathi kusayithi, udinga ukwazi ukuthi kanjani, kanjani, nokuthi nini okufanele uyenze. Eqinisweni, i-acidity yikhuphuka lokuqukethwe kwama-hydrogen ions emhlabathini. Lesi sakhi samakhemikhali asivumeli izitshalo zikhule ngokugcwele. Ngezinga eliphezulu le-acidity, uhlelo lwempande lungafa ngisho nokufa. Ngaphezu kwalokho, yonke imizamo yokuthuthukisa isimo nama-fertilizer kubangelwa ukwehluleka, ngoba ngenxa ye-hydrogen ions, noma iyiphi imanyolo eyengeziwe ingaguquka zibe ngamaminerali angakulungele ukuhlanganiswa kwezitshalo. Ingxenye enkulu yalezi zitshalo zivame ukukhula emhlabathini, ukuphendula kwe-pH okuphakathi kuka-5.5-6.5 (ubuthakathaka obunobuthi ne-neutral). Izinkomba ezinjalo ngokuvamile zihambisana nemhlabathi equkethe inani elanele lama humus. Enhlabathini enomsoco kukhona okuningi kwama-manganese ne-aluminium, okwenza izitshalo zicindezeleke. Ngokuvamile, nge-acidity engaphansi kwe-5 pH, kufanele nakanjani ucabange ngendlela yokuchitha inhlabathi ekwindla. Lokhu kuyadingeka ukuze ukwandise ukugeleza kwe-calcium, i-molybdenum, i-phosphorus ne-magnesium, futhi unciphise ithonya lama-manganese, insimbi kanye ne-aluminium. Ngaphezu kwalokho, ukuxuba umzimba kukhuthaza ukugcinwa kwe-nitrogen enhlabathini.
Ngokuvamile, ukuchithwa kwenhlabathi kwenziwa nge-lime, okuthiwa "pushenka". Uma i-lime ingasaphuliwe ngaphambilini, i-alkali iyobuthelela emhlabathini, futhi ukushisa okukhishwe ngesikhathi sokuphendula kungaholela ekushiseni izimpande. I-Norm ye-lime ikhethwe uhlobo oluthile lwenhlabathi. Futhi, ukungcola kwenhlabathi kuqhutshwa ufulawa wase-dolomite, usimende oludala, isikhombe noma i-plaster eyomile. Kulesi simo, izinto ezixoshwayo zizodinga ngaphezulu kwezingu-30%. Uma udoxisa umhlabathi nge-choki, i-gypsum noma i-alabaster, thatha i-deoxidizer kabili kakhulu. Qaphela ukuthi komuntu ezinye zalezi zinto azizuzisi kakhulu, futhi, isibonelo, ukuxosha umhlaba ngomlotha wamalahle kuzodinga u-slag izikhathi ezingu-10 ngaphezulu!
Uma isayithi lincane, unganciphisa ubuhle be-acid enhlabathini ngosizo lwegobolondo leqanda. Ukwenza lokhu, kancane kancane othosiwe epanini lokuthosa, ubeke kancane bese utshala ungqimba omncane emibhedeni.
Kweminye imithombo umuntu angathola ulwazi lokuthi ezinye izakhamuzi zasehlobo zenza ukungcola kwenhlabathi, kodwa abaningi be-agrotechnists bacabangela le ndlela engathandeki kakhulu. Iqiniso liwukuthi i-sodium equkethwe kuyo iyakwazi ukubuthelela, futhi okweqile kungalimaza izitshalo ngisho nangaphezulu kwenhlabathi ye-asidi.
Abasizi bezitshalo
Ngaphandle kwezinto ezibalwe ngenhla, zikhona
Yiziphi ezinye izitshalo ezithwala inhlabathi? Le-birch, i-alder, i-spruce, i-elm, i-hornbeam ne-pine inganciphisa ubuhle be-asidi yomhlabathi kuya ekujuleni kwemitha.
