Nthaka acidity ndi njira mtima wake

Mipweya ya dothi zosiyanasiyana kusiyana kwambiri ndi kukhalapo ndi mlingo ali m'bukuli, zinthu zimachitikira ndi mankhwala awo. mfundozi bwanji chonde wa nthaka ndi zizindikiro zina za mbewu zomera zina.

The pH acidity

Nthaka khalidwe chizindikiro ndi pH mlingo lolingana mlingo wa ndende ya ayoni wa hydrogen mu njira zadothi. Njirayi imatchedwa muyeso wa acidity ndipo amatchedwa pH lapansi.

acidity wa nthaka zimadalira mankhwala ake zikuchokera. Ndi m'maderawo zamchere kapena ndale. Zamchere ndi acidic dothi zina agawanika pa gradations malire. Malinga ndi kuchuluka kwa acidity za nthaka ndi mwamphamvu acidic, ofooka ndi modekha, ndi zamchere, ofanana, ofooka, mwamphamvu ndi sredneschelochnymi. The acidity wa pH nthaka kumawonjezera ku acidic kuti zinthu zamchere. Amaona kuti ndale pH = 7. Ngati ndi zochepa, ndiye nthaka imatengedwa acidic, pamwamba - zamchere. Mtengo wa acidity zimakhudza khalidwe la chitukuko ndi kukula kwa zomera. Kwathunthu kuwaphunzira zofunika zakudya zomera zokha ndale nthaka. Ngakhale feteleza wabwino si kulenga zinthu zomera zikule pa pH amene ali apamwamba kapena poyerekeza ndale.

dothi Acidic ndi:

- pH = 4 ndi zosakwana - kwambiri acidic;

- pH wa pa 4 ndi 5 - modekha;

- pH pakati pa 5 ndi 6 - ofooka acidic.

dothi ndale ndi pH a 6.5-7.

dothi zamchere ndi:

- pH 7-8 - ndi pang'ono zamchere;

- pH 8-8.5 - izo sredneschelochnye;

- pH 8.5 kapena apamwamba - kwambiri zamchere.

Nthaka acidity umakhudza mlingo wa malowedwe mu minofu ya zomera za zitsulo zili m'nthaka. Pa pH ndale zitsulo kukhala mu mkhalidwe omangidwa ndi zochepa yaing'ono amasonkhana zomera. Pa yemweyo dothi nthawi acidic ndi pH otsika monga ambiri zotayidwa, manganese ndi chitsulo mu mawonekedwe a chakupha kuti zomera.

Komanso ndi radionuclides: pH zimakhudzanso mmene mayamwidwe awo mu mbewu. Pa nkhani imeneyi, tikhoza kunena motsimikiza ndithu kuti ndale nthaka zakudya zofunikira ndi optimally chosakanikirana ndi zomera, ndi mayamwidwe zinthu zoipa ndi negligible.

Khama la acidity nthaka

zomera ambiri amakonda pang'ono acidic ndi ndale dothi. Nthawi zina mu kukula kwa namsongole n'zotheka amanena acidity wa nthaka, koma chifukwa chakuti namsongole zikukangalika kuwonongedwa, ndi chodziwikiratu kuti n'zotheka molondola kuweruza acidity. Kodi kudziwa acidity wa nthaka? Kuti mudziwe izo, mungagwiritse ntchito mapepala mayeso (TU16-09-1181-71). M'masitolo mugule ya n'kupanga fyuluta. Osasankhidwa n'kupanga utoto mu kuwala lalanje mtundu, asonyezedwa ❖ kuyanika zikusonyeza kuti wasintha hue malingana ndi msinkhu pH.

tebulo appended kukhazikitsa amasonyeza acidity wa nthaka, malingana ndi mtundu anasankha.

Pofuna kudziwa mlingo wa acidity wa nthaka zikutengedwa kusanthula pa kuya osiyana mu madera osiyana a chiwembu. nthaka ndi atakulungidwa mu nsalu wandiweyani, ndi yomatidwa ndi kuikidwa madzi. Tengani mbali imodzi nthaka ndi mbali 4-5 madzi. Kenako, yankho chotsatira anamizidwa zadothi chizindikiro pepala. Mtundu chifukwa collate ndi sikelo ya kudziwa acidity.

Pakuti yovuta kusanthula nthaka pepala asidi-m'munsi ziwiri akuda angagwiritsidwe ntchito, koma kwa kusanthula zolondola - "m'madzi", pepala chonse, kapena zizindikiro zina kuti yaing'ono pH osiyanasiyana. Kodi ndizitani ngati dothi acidic pa dzinja kanyumba awo? Pofuna kuthetsa vutoli, mukhoza kupanga izo mu phulusa, choko, laimu, ufa nyumba simenti. Pamene kwambiri nthaka zamchere ayenera kuwonjezera dzikolo ndi anachita acidic kapena ndale, ndi nthaka ya mitundu yosiyanasiyana kusakaniza bwinobwino.
