Ekupheleni kwehlobo, abahlali basehlotyeni bavuna isivuno, balinganisa ixesha eliphela, kwaye balala phantsi kweemeko zonyaka wokuvuna ukuba zilungele phambili, kwaye zibhetele. Kwaye zonke izilwanyana ezikhula kwisiza, zifuna ukunakekelwa kunye nokunyamekelwa, ngenxa yokuba ngaphezu kweyodwa kuya kufuneka zikholise ngokubuyisela ngesimo sezityalo eziqholiweyo kunye nemifuno emitsha.
Akunabo bonke abalimi abafumana iziqhamo ngomhlaba onothambile. Ukuba isayithi ingekho kude nehlathi, i-horse sorrel, i-fern kunye neentlobo ezahlukeneyo zehlathi ezikhulayo zikhule ngokugqithiseleyo, ngoko kuya kugqitywa ukuba umhlaba apha ubonakaliswe ngobuninzi be-acidity. Ngaphandle kokuthatha amanyathelo afanelekileyo wokukhupha umhlaba, ubeka umngcipheko wokulahlekelwa isityalo owawubale ngaso. I-Strawberries, utamatisi, iklabishi kunye namakhukhamba emhlabeni kunye ne-acidity ephezulu ayikhulanga njengoko ungathanda.
Indlela yokujongana ne-acidity yomhlaba?
Ukuze unqambi umhlaba kwindawo leyo, kufuneka ukwazi ukuba, yintoni, kwaye nini ukwenza. Enyanisweni, i-asidi yinyanzelo yokwanda kwama-hydrogen ions emhlabeni. Olu hlobo lweekhemikhali aluvumeli izityalo ziphuhlise ngokupheleleyo. Ngomgangatho ophezulu we-asidi, inkqubo yeengcambu inokufa. Ukongeza, zonke iinzame zokuphucula imeko kunye nezichumisi ziphumela ekuphumeleleni, ngenxa yokuba i-hydrogen ions, nayiphi na isichumisi esongeziweyo iyaba ngamaminerali engafanelekanga ukuhlanganiswa kwezityalo. Inxalenye ebalulekileyo yezityalo ngokuqhelekileyo ikhula kwimihlaba, ukuphendula kwe-pH ekhoyo kwi-5.5-6.5 (ubuthaka obuthathaka kunye nenhlabathi engathathi hlangothi). Ezi zikhombisi zivame ukuhambelana nomhlaba onomlinganiselo okwaneleyo we-humus. Kwihlabathi enomsolo kuninzi yama-manganese kunye ne-aluminium, eyenza iyancipha izityalo. Ngokuqhelekileyo, nge-acidity engaphantsi kwama-5 pH, kufuneka ucinge ngokucwangcisa umhlaba. Oku kuyimfuneko ukwenzela ukwandisa ukuhamba kwe-calcium, i-molybdenum, i-phosphorus kunye ne-magnesium, kunye nokunciphisa impembelelo yamanganese, isinyithi kunye ne-aluminium. Ukongeza, ukukhutshwa komzimba kukukhuthaza ukugcinwa kwe-nitrojeni emhlabeni.
Ngokuqhelekileyo, ukuxutywa komhlaba kwenziwa nge-lime, okuthiwa "pushenka". Ukuba i-lime ayidluli ngaphambili, i-alkali iya kubuthela emhlabeni, kwaye ukushisa okukhutshwe ngexesha lokuphendula kungakhokelela ekutsheni kweengcambu. I-Norm ye-lime ikhethwe ngohlobo oluthile lomhlaba. Kwakhona, ukuxutywa komhlaba kuqhutywe ngomgubo we-dolomite, i-sement endala, isitya okanye i-plaster eyomileyo. Kule meko, izinto ezixakekayo ziza kufuna 30% ngaphezulu. Xa ukhupha umhlabathi nge-chaki, i-gypsum okanye i-alabaster, thabatha i-deoxidizer kabini. Qaphela ukuba kumnye wale nto ayiluncedo kakhulu, kwaye, umzekelo, ukukhupha umhlaba ngomlotha wamalahle kuza kufuna amaxesha angaphezulu kwama-10!
Ukuba isayithi incinci, unokunciphisa ubudibanisi bomhlaba ngoncedo lwegobolondo leqanda. Ukwenza oku, i-fried frying epanini yocingo, ubeke umgangatho omncinci kwaye uhlwaywe ungqongqo onqabileyo kwiibhedi.
Kweminye imithombo umntu unokufumana ulwazi lokuba abanye abahlali behlobo baqhuba ukukhutshwa komhlaba, kodwa abaninzi be-agrotechnists bajonga le ndlela ingathandeki. Inyaniso kukuba i-sodium equlethwe kuyo iyakwazi ukuqokelela, kwaye ukugqithisa kwayo kungonakalisa izityalo ngaphezu komhlaba we-asidi.

Ziziphi ezinye izityalo ezichitha umhlaba? Le bharch, alder, spruce, elm, hornbeam kunye nepine inokunciphisa ubunqamle bomhlaba kwiqondo elingaphantsi kwemitha.
