PODZOLIC ivhu hunotifambira podsolic muitiro. kunonyanyisa vachiona Its unoratidzwa coniferous musango.

Zviri pano ine zvakafanira zvose ezvinhu kuti ndima yacho: mvura chomumba rudzi, maitiro - yakatsiga-acidic, kungatikanganisa Organic acids.

Nemarara raimiririra zvikurukuru faibha, tannins uye lignin, ayo akaita - acidic, asi karusiyamu oxide uye rine kukwana. It yaora ainyanya notumwe, uye kunosimudzirawo paumbwe kungatikanganisa fulvic acids. Mukuwedzera, okumusoro akaturikidzana ivhu pachena kuti simba Washing panze soluble yeimwe uye kuparadzwa hwakarongwa ivhu zvicherwa. Munguva azvaiitwa kuiparadza zvibereko kuparadza uye, pamwe chete nomunhu asidhi uye mvura dziri akasiya pazasi.

Somugumisiro - anomira kunze podzolic kana eluvial mujengachenga, sezvamakaropafadzwa yakaderera simba chinhu zvinomera, sesqui oxides ose aruminiyamu uye simbi, silt nezvimedu, asi yakawanda crystalline Goldstone (SiO2) uye amorphous silica (SiO2 • H2 O) iyo iri jengachenga uye dzinowana chiedza chawo wachena ruvara, akafanana ruvara nemadota.

Mamwe zvinhu kuti zvawave kusukwa podsolic jengachenga nemarara, vari wakaiswa pazasi eluvial rukoko uye dzinoumba jengachenga washout - illuvial rukoko. It anezvakawanda ivhu uye colloidal nezvimedu esimbi oxides uye aruminiyamu, phosphorus yeimwe uye vamwe manyowa. Ruvara jengachenga iri kazhinji yakatsvukuruka mashava.

Mumwe uwandu zvinhu zvakatendeka kusukwa okumusoro kunosvika pamusoro subsoil mvura akarasika uye ivhu profile. Saka, musimboti wacho podzolic kwacho kunoratidza pachayo iri kuparadzwa zvicherwa pamusoro ivhu pasi pokudzora ane iine acid maitiro uye haizopereri redistribution chezvinhu yokuparadza yavo yose profile. Zvinonzi aidaviravo kuti izvi zvingaitika akabatana lessivage (kubviswa yokumusoro ivhu akaturikidzana zvevhu nezvimedu pasina kuparadza maumbirwo yavo).

Podzolic ivhu Profile vane zvinotevera yakarongeka: A 2 O + A + B + C

A O - imwe hafu, imwe Ukobvu 3 - 5 masendimita randinogara pamwe yaora uye undecomposed residues chikwindi, lichen, tsono, zvidimbu nemakwati uye zvakadai.

A 2 - iri eluvial kana podzolic rukoko yakanga whitish kana chena-kuchena, kuva kusimba stratified-platy mamiriro kana zvachose structureless, pakukora kupfuura kota munhu mita.

B - iri illuvial dzvuku mashava kana shava rukoko gobvu, kuva prismatic kana blocky yakarongeka, mumwe Ukobvu rimwe meter, rinogona rakakamurwa subhorizons - B 1, B 2, zvichingodaro.

C - ndiwo mubereki dombo anomiririrwa kunyanya carbonate isina ivhu kana loam. Pamuganhu nemarara uye podsolic jengachenga anogona govera rukoko A 0 A 1, imwe Ukobvu 2 - 3 masendimita, zvinosanganisira tsime pasi emarara yaora kana mavara zvinhu manyowa chapamusoro chicherwa Profile A 1 A 2.

Podzolic ivhu pamusoro ehupfumi vanoshorwa kurima pairi. The manyowa jengachenga hapana anoita hapana maitiro - zvakasimba acidic (ph = 4.0-4.5), ayo Absorção de Água vanokwanisa - kubva MG • eq / 100 magiramu 3 kusvika 15 ivhu, riri zvikuru diki. Uyezve, podzolic zvakakangwa zvishoma nezvigadziko - kubva 30 kusvika 40%.

Zvinovaka muviri zvakadai phosphorus, potassium, senitrogen uye vamwe uyewo diki. Podsolic ivhu structureless, kushambira pashure mvura chimiro zvakakwana gobvu keke pashure kuomesa. Izvi zvose ine kunambwa zvinomera.

Nokuti kurimwa munyika dzakadaro, vanofanira limed, kuti wakakwidzwa tsika zvose Organic uye chicherwa fetiraiza. Kurima podzolic nevhu vanoda kudzika 24 masendimita uye nechokwadi kurapwa kwavo maererano nemirau.
