Mayelana namaphutha ajwayelekile kakhulu lapho enza umanyolo ojwayelekile, ongoti abavela e-State University of Mississippi, e-USA, uLarry Oldham no-Eric Larson batshelwa.
Umanyolo ushise
Uma umanyolo efakwa kanye nembewu noma eduze kakhulu nabo lapho behlwanyela, kungenzeka ukuthi bashise.
Umanyolo amaningi usawoti ochithwa kuma-oon ahambisanayo emanzini enhlabathi. Cabanga usawoti wetafula, oncibilika emanzini uye kwi-na + ne-heath. Lokhu kuchithwa kwakha ukwehla kwengcindezi, ngakho-ke amanzi asuka ezimpandeni zezitshalo enhlabathini ezungezile (I.e. Osmosis). Izitshalo zingaphela, zibuyiselwe emuva futhi zife ngenxa yokuntuleka kwamanzi. Lokhu kubizwa ngokuthi umanyolo kushise futhi kungaholela ekulahlekelweni okukhulu kokuhluma.
Lesi simo ekusakazweni kwendabuko komanyolo kuyaqabukela kwenzeka, ngoba sebehanjiswa endaweni enkulu.
Ngokufanayo, ukuqala komanyolo ngemichilo engu-5 cm ngaphezulu kanye ne-5 cm ngezansi yindlela eyenzelwe ukuvikela ukuxhumana nezithombo. Umanyolo oncibilikayo kahle onenkomba ye-saline ephansi kufanele usetshenziswe, njenge-ammonium polyphosphate (10-34-0) noma ama-orthophosphates. Abathengisi abathengisi kanye nabeluleki kufanele bajwayelane nezincomo ezifanele zalezi zinhlelo zokusebenza.
I-Ammonia uShistoLapho usebenzisa umanyolo we-nitrogen, kunengozi eyengeziwe yokulimala, engalindelwa ukuthi ilwe yodwa okuqukethwe usawoti uma i-ammonia yabelwe lapho ngingena emhlabathini.
I-Ammonia inobuthi futhi ingangena ngokukhululeka kumaseli ezitshalo.
U-Urea, CAS, AMmomonium Thiosulfate neDaymonieumphate (DAP) amele izinkinga eziningi ezihambisana ne-ammonia kunemephu, i-ammonium sulfate noma i-ammonium nitrate.
Ukuchithwa kwe-ammonia kungasheshiswa ngenxa yamanani aphezulu we-PH noma inqwaba yenhlabathi, noma ngenxa yokusabela okusondelene namanyolo owenziwe.
Isimo sezulu nenhlabathi kubalulekileIzimo zenhlabathi zibalulekile ukunquma ukuthi kungani ukulimala kungavela eminyakeni ethile, hhayi kwabanye.
Ukulimala kokuvunwa kungenzeka kakhulu lapho izithombo zikhula enhlabathini enesihlabathi esinokuqukethwe okuphansi kwezinto eziphilayo zithinteka ngqo kumanyolo.
Isimo sezulu esomile sandisa amathuba okulimala. Emhlabathini omanzi, usawoti womhlinzeshini uvinjelwe ngokuphazamiseka kude nomucu, kepha ukuguquguquka akuveli emhlabathini owomile. Umanyolo ohlanganisiwe ukhulisa ubungozi bokushiswa.
Inhlabathi enekhono lokushintshana kwe-coation eliphansi elinesakhiwo esibi nokuqukethwe kwento ephansi kwe-organic kusabela kancane ngomanyolo kunokuba nenhlabathi enekhono eliphakeme lokushintshaniswa kwe-coation (okugobile).
Ukushisa kwenhlabathi nakho kuyingxenye yenkinga, ngoba izimpande zikhula kancane emhlabathini obandayo, futhi zivezwe isikhathi eside kumanyolo wokuhlushwa okuphakeme.
