Xa unesitiya uya kufuna uluhlu lweemfuno ezisisiseko ukuze izityalo zikhule, ezifana nokukhanya kwelanga, amanzi, iiminerali kunye nezondlo ezibalulekileyo zezityalo. Nangona kunjalo, kukho uphawu olubalulekileyo ekufuneka luqwalaselwe ukuchuma kwegadi kwaye yi pH yomhlaba. Fumana kweli nqaku ukuba yintoni kunye nendlela yokulinganisa i-pH yomhlaba. Qhubeka ufunda eli nqaku linika umdla.
Yintoni umhlaba pH?
Umhlaba pH ngumlinganiselo weasidi kunye ne-alkalinity kwindawo ethile yomhlaba. Ubumuncu bomhlaba bulinganiswa ukusuka kwi-0.0 (eyona acidic kakhulu) ukuya kwi-14.0 (uninzi lwe-alkaline/esisiseko), kunye ne-7.0 njengesiseko esingathathi hlangothi. Umhlaba we-Acidic uqulethe iikhompawundi ezinobunzima, ezifana ne-aluminium sulfate okanye i-sulfuric acid; Umhlaba onealkaline uneekhompawundi ezisisiseko, ezifana necalcium carbonate. Imiba emininzi inokubangela ukuba iimeko zomhlaba zibeneasidi okanye ialkaline, ukusuka emvuleni ukuya kwizichumisi, imathiriyeli engumzali, kunye nobume bomhlaba (umz., isanti ngokuchasene nomhlaba wodongwe). Phambi kokutyala iziqhamo okanye imifuno egadini yakho, kufuneka wenze uvavanyo lomhlaba ukujonga ipH yomhlaba wakho kwaye ubone ukuba kufuneka wenze nayiphi na ipH utshintsho phambi kokutyala.
Yintoni echaphazela umhlaba pH?
Xa uzama ukubona indlela yokulinganisa i-pH yomhlaba, kufuneka uqonde ukuba ayisiyondlela elula; Izinto ezininzi zinokwenza iimeko zomhlaba zibe asidi okanye zibe sisiseko. Okokuqala, amanzi emvula ahlamba izondlo ezithile ezisisiseko (ezifana ne-calcium ne-magnesium), eshiya izondlo ezineasidi (ezifana ne-aluminiyam kunye nentsimbi) ngasemva. Oku kuthetha ukuba imimandla enemvula eyongezelelekileyo ngonyaka inemihlaba eneasidi eninzi, ngelixa iindawo ezinemvula encinane zikholisa ukuba nomhlaba omninzi onealkaline.
Enye into ekufuneka iqwalaselwe xa ulinganisa i-pH yimathiriyeli yabazali bomhlaba, okanye izinto eziye zaphuka ukuze zibe ngumhlaba, onempembelelo enkulu kumhlaba pH. Umzekelo, umhlaba ovela kumatye e-alkaline uya kuba ne-alkaline ngakumbi kunemihlaba ephuma kumatye aneasidi. Ukongezelela, izichumisi kufuneka ziqwalaselwe, kuba uninzi lwazo kunye nezichumisi ze-nitrogen zine-acidic (ngoko ukusebenzisa isichumisi esininzi kunokutshisa iingcambu zezityalo).
Ukuba umhlaba kwindawo ethile uxutywe nesichumiso unyaka nonyaka, kunokwenzeka ukuba ube neasidi ngakumbi kunomhlaba ongaxutywanga. Okokugqibela, kufuneka uqwalasele uhlobo lomhlaba, njengoko ukumila kwawo kuhluka ngokwesikali ukusuka kwisanti ukuya kudongwe, kwaye oku kungamisela ukuba umhlaba uya kuthatha utshintsho olukhawulezayo lwepH okanye hayi. Imihlaba eyisanti ine-organic matter encinci kunye nethuba eliphezulu lokungena kwamanzi, nto leyo eyenza ukuba ube sesichengeni sokuba neasidi ngakumbi. Imihlaba eludongwe inento eninzi yendalo ephilayo kwaye imelana namanzi kangangokuba inesakhono sokugquma esiphezulu, nto leyo eyenza ukuba imelane notshintsho kwipH.
Kutheni kubalulekile ukujonga ipH yomhlaba wakho?
Ukuvavanya i-pH yomhlaba wakho kubalulekile kwigadi yakho kuba imisela impilo yezityalo zakho. Ngokulandelayo, iyunithi ye-pH yepasile yomhlaba iqaqambisa ukufumaneka kwezondlo, okuthetha ukuba izityalo ezithile zithatha i-micronutrients bhetele kumanqanaba athile e-pH. Zonke izityalo zinomhlaba ofanelekileyo we-pH wokukhula ngokufanelekileyo, oku kuthetha ukuba ukuba umhlaba wakho pH i-acidic kakhulu okanye isisiseko kakhulu kwizityalo ozama ukukhula, izityalo aziyi kuphumelela kwaye zingafa.
Inokukongela ixesha kunye nemali. Abalimi abaninzi abaqalayo bacinga ukuba ukukhula kakubi kwezityalo kungenxa yokunqongophala kwezondlo, ngoko baya kuchitha ixesha elininzi kunye nezixhobo zokuthenga izichumisi okanye ezinye izongezo zokuchuma komhlaba ukuze babuyisele izitiya zabo endleleni. Endaweni yoko, weqa umsebenzi wokuqagela kwaye ujonge i-pH yomhlaba wakho ngaphambi kokuba uqale ukutyala. Kusenokufuneka ufake izilungiso zomhlaba ezifana ne-peat moss, uthuthu lomthi, izinto zokugalela ikalika (ezifana ne-dolomitic limestone), okanye iinaliti zompayina egadini yakho. Ezi zilungiso zitshintsha ixabiso le-pH, ziqinisekisa ukuba izityalo zakho zineemeko ezingcono zokukhula.
Ulinganisa njani umhlaba pH?
Uvavanyo lwe-pH yomhlaba yindlela eyonwabisayo nelula yokuzisa isayensi ekhayeni lakho. Unokuvavanya umhlaba pH ekhaya ngeendlela ezahlukeneyo, nokuba uthenga ikiti okanye usebenzisa izithako zendlu. Indlela yokuqala yokulinganisa i-pH kukusetyenziswa kwemicu yokuvavanya, eyesibini yindlela esetyenziswa ngokubanzi, apho uya kufuna i-baking soda kunye neviniga, ekugqibeleni, uya kuba nendlela yokulinganisa i-pH ngokubomvu. ikhaphetshu Ukuba ufuna ukwazi nganye kwezi, siya kuchaza:
Sebenzisa imicu yovavanyo lomhlaba: Eyona ndlela ilula nethembekileyo yokulinganisa i-pH yomhlaba wakho kukusebenzisa ikiti yovavanyo lomhlaba, onokuthi uyithenge nakweliphi na iziko legadi yasekhaya okanye kwi-intanethi. Ukuvavanya ipH yomhlaba wakho ngekhithi yovavanyo, landela nje imiyalelo kwaye uthelekise iziphumo zakho zovavanyo kunye nekhithi yepH chart okanye imitha. Inzuzo yale ndlela kukuba ikiti yovavanyo lwe-pH iya kukunika inani le-pH elichanekileyo, kunokuba likuxelele nje ukuba umhlaba wakho i-pH ineasidi okanye i-alkaline.
Isoda yokubhaka kunye neviniga: Ukwenza uvavanyo olukhawulezayo lwasekhaya malunga nobumuncu bomhlaba wakho okanye ubumuncu, qokelela intwana yomhlaba egadini yakho uwubeke ekomityini. Yongeza i-splash yeviniga emhlophe kwaye ukuba umhlaba uyaqhuma, umhlaba wakho une-alkaline. Ukuba umhlaba wakho awuhambisani neviniga, faka esinye isandla somhlaba kwikomityi eyahlukileyo kwaye wongeze amanzi adibeneyo kude kube yi-slushy. Fafaza icephe lesoda yokubhaka phezu kodaka, ukuba liyagqabhuka, umhlaba wakho uneasidi.
Sebenzisa indlela yekhaphetshu ebomvu: Ngovavanyo olulodwa lomhlaba lwe-pH, galela amagqabi ekhaphetshu abomvu kwiikomityi ezimbini zamanzi adityanisiweyo ubuncinane imizuzu eli-10, emva koko uwayeke anyuke imizuzu engama-30. Susa amaqabunga kunye namanzi kufuneka abe ngumbala omfusa onzulu kunye ne-pH engathathi hlangothi ye-7. Ukuvavanya umhlaba, yongeza i-tablespoon yomhlaba kwi-jar kunye neepunipopu ezimbalwa zamanzi eklabishi. Emva kwemizuzu engama-30, amanzi ekhaphetshu kufuneka atshintshe umbala wokufunda i-pH: obomvu-pinki kumhlaba oneasidi, ipurplish-blue kumhlaba ongathathi hlangothi, okanye oluhlaza okwesibhakabhaka kumhlaba wealkaline.
Ulwenziwa nini uvavanyo lwe-pH yomhlaba?
Ukulinganisa i-pH yomhlaba wakho kufuneka ibe yinto kuluhlu lokutshekisha lwegadi yakho yokuwa. Ngaloo ndlela unokulungisa umhlaba ngaphambi kobusika okanye entwasahlobo ngaphambi kokutyala. Kwakhona, eli lixesha elilungileyo lokujonga kulo naluphi na ukhula olukhule ehlotyeni, olunokukunika umkhondo malunga nepH yomhlaba wakho. Ngokomzekelo, iidandelion, amaqunube asendle, neebhanana zichuma kumhlaba oneasidi, ngoxa i<em>chickweed, iminqathe yasendle ne<em>radicchio ithanda umhlaba onealkaline.
Kwakhona, ukuvavanya i-pH yomhlaba ekwindla kukunika ixesha elininzi lokutyala isityalo sokugquma sokulungiswa kwenitrogen (kwimozulu epholileyo yasebusika) okanye ukulungisa ukutyala konyaka ozayo ukuze kuhambelane nokufunda kwakho. Kwimeko yomhlaba we-alkali, unokunciphisa i-pH ngokufaka izinto eziphilayo, ezifana ne-peat moss. Nangona kunjalo, kwimeko yomhlaba we-asidi inokungathinteki ngokugalela ikalika. Ungakanani ukongeza kuxhomekeke ekubeni kufuneka utshintshe kangakanani i-pH yakho.
Iingcebiso zoVavanyo lwe-pH yomhlaba
Ukuba uvavanya umhlaba wakho ngeviniga kunye nesoda yokubhaka kwaye akukho vavanyo luvelisa impembelelo eninzi, umhlaba wakho mhlawumbi ukwindawo engathathi hlangothi. Akukho bungqina bungaphezulu obufunekayo. Ungaxuba umhlaba kwiisampulu ezintathu okanye ezine ezahlukeneyo kwigadi encinci yeviniga kunye novavanyo lwesoda yokubhaka. Nangona kunjalo, ukuba unegadi enkulu, kungcono ukuvavanya iisampuli ezininzi ngokwahlukeneyo. Kumhlaba wegadi ongavelisi kwanto, kungcono uthumele isampulu yomhlaba kwilebhu ukuze ihlalutywe ngentlawulo encinci. Emva koko, ngokusekwe kwiziphumo, iingcali zinokwenza iingcebiso zokukubuyisela kwindlela.
Ngowuphi owona mhlaba ufanelekileyo pH?
Uluhlu lwe-pH olufanelekileyo kwizityalo ezininzi zokutya lune asidi kancinane: phakathi kwe-5,5 kunye ne-6,5. Izityalo ezithile ziya kukhetha iimeko ezahlukileyo kancinci, umzekelo, iipayinapile, amaqunube, azaleas kunye nerhododendrons zaziwa ngokuba "zizityalo ezithanda iasidi" kuba zikhula kumhlaba oneasidi eninzi (phakathi kwe-4.0 kunye ne-6.0). Izityalo ezifana ne-asparagus, i-honeysuckle, kunye ne-lavender inokusingatha iimeko ezininzi ze-alkaline (phakathi kwe-6.0 kunye ne-8.0). Khangela kwi-intanethi okanye kwivenkile yegadi ukuze uqinisekise ukuba izityalo ofuna ukuzikhulisa zinomhlaba ofanayo okhethiweyo pH.
Ukuba ulithandile eli nqaku Indlela yokulinganisa i-pH yoMhlaba, siyakumema ukuba ufunde amanye amanqaku aqulethe izihloko ezinomdla kwezi zikhonkco zilandelayo:
