Ubuninzi be-acidity bomhlaba buphazamisa izityalo kwaye buphule izityalo zabo. Kukho iqela elincinane lezityalo ezikhulayo kakuhle kwihlabathi ezinamandla, umzekelo, i-cranberries. Kodwa izityalo ezininzi zintsimi zikhetha inhlabathi ephakathi kunye ne-weakly acid. Ukongezelela, inhlabathi ye-asidi yomile kakuhle, kwaye iyomile, ihlanganiswe ngokukhutshwa kanzima. Ukunciphisa i-asidi equlethwe ngumhlaba, ukukhawulwa komhlaba kwenziwa. Ukongezelela, ukukhawulelwa kwehlabathi enomsoco kuphucula isondlo sezityalo zegadi, ngenxa yokukhula kwenkqubo yenkcenkomo enamandla ephuhliswayo kumhlaba ongekho acidiki.
Izinto ezinobulunga
Izixhobo zemibala yemvelaphi yemvelo (i-limestone, i-dolomites, i-marl) kunye ne-lime equkethe inkunkuma ye-teknologi (i-shale ash, uthuli lomsila, i-sludge emhlophe) isetyenzisiweyo. Zonke ezi zinto zinokubunjwa kwazo okanye i-chalk okanye i-calcium carbonate ngokulinganayo. Kodwa yintoni enye engcono ukuyibeka umhlaba? Abagadi bezolimo abanamava amaninzi bayacetyiswa ukuba basebenzise izichumisi ezivelisiweyo ezikhutshwe ngezezimboni, apho iingxenye ezili-10 ze-calcium zibika iingxenye ezi-4 ukuya kwezi-8 ze-magnesium. Ukuqaliswa kwengxaki elinezinto zombini kukhuthaza ukwanda kwintlobo yezivuno ezininzi kwizinga elingaphaya kokusetyenziswa kwezichumisi ezingenalo i-magnesium.
Ukuphindaphinda kwamaxabiso
I-Agrotechnics iyanconywa ukuba yenze i-liming yomhlaba kwi-dacha kanye yonke iminyaka engama-6 ukuya kwe-8, kuba ngenxa yenkqubo eyenzekayo emhlabathini, ukuphendulwa kwemvelo kuyashintsha kancane kancane, kubuya iminyaka emininzi kwinqanaba lokuqala.
Indlela yokujonga ukuba umhlaba ufuna ukukhawuleza kangakanani?
Umhlaba ukhutshwa yi- lime, ukhokelwa yimpawu zangaphandle zomhlaba. Okokuqala, inhlabathi enamandla kakhulu ne-white hue kunye ne-gray-white hue kunye ne-podzolic horizon kunye nobukhulu obungaphezu kwama-10 cm kuyadingeka ekunciphiseni. Ukufuneka kwemilinganiselo izimisele ngokubaluleka kwezityalo kunye nokukhula kokhula. Ubuninzi obubonakalayo kwi-acidity bufumaneka ngqolowa, i-clover kunye ne-beet, ukukhula kobuhlwempu kukubonisa ukuba ukufunyanwa kwexesha elikhawulezayo lomhlaba kuyadingeka. Olunye ukhula lukhula kakuhle kwihlabathi le-asidi. Ukukhula kweentloko, iLedum, i-buttercup, i-pike, i-sorrel nayo ibonisa ukuba i-acidification yomhlaba egqithiseleyo. Xa kuthengiswa kukho izikhombisi zephepha eziza kunceda ukubonakalisa umxholo we-asidi emhlabathini.
Ndifanele ndenze nini i-lime?
Ekuqaleni, i-lime isetyenziswe xa ubeka umyezo ngexesha lokulungiselela isayithi. Emva koko inkqubo yokusebenzisa isichumisi se-limestone yenziwa entwasahlobo (ekwindla) ngaphambi kokuba umhlaba uphantsi.
Izinga apho isiqhekeza sisetyenziselwa umhlaba
Imilinganiselo yesicelo se-hydrated lime ngomhlaba kuxhomekeke kwi:
- asidi yomhlaba;
- ukwakheka komhlaba;
- iintlobo zamacilisi e-limestone esetyenzisiweyo;
- bunzulu bokungena.
Nge-asidi ephezulu, i-lime ifakwe kwihlabathi kumanani amakhulu. Nge-asidi enamandla kakhulu, i-0.5 kg ye-calestone nganye ye-1 m2 isetyenziselwa ngodongwe kunye nenhlabathi ye-loamy, i-0.3 kg kunye nenhlabathi enesihlabathi. Nge-asidi ye-acidity-ngokulinganayo 0.3 kg kunye no-0.2 kg. Kwi-asidi ebuthakathaka - udongwe kunye ne-loamy engama-0.2 kg isetyenzisiwe, inhlabathi enesihlabathi ayikho i-limy.
Indlela yokwenza i-lime emhlabeni?
Ngokuqhelekileyo abalimi abazi indlela yokucima ihlabathi ngokufanelekileyo. I-lime engalindelekanga yenziwe ibe ngumgubo kwaye ifakwe ngamanzi ukucima. Iqhekeza elinomquba otyumkileyo ngokukhawuleza udibaniswe nomhlaba. Ukunyanzelisa i-lime nomhlaba kuyimfuneko yokukhawulela ngokufanelekileyo.
Isenzo kwiimfom zomhlaba
Imifuno yomhlaba ayizalanga kakuhle enhlabathini ye-asidi, ngoko ukuphatha umhlaba nge-lime ngobungakanani obonisiwe, inomphumo onokubaluleka kubemi bezi zidalwa ezizuzisayo.
