ciidda podzolic waxaa saameeya geedi socodka podsolic. Its gaadhista ugu badnaan lagu muujiyay kaynta dhilka.

Waxaa halkan waa ku jira oo dhan shuruudaha lagama maarmaanka u ah in ay marinka biyaha hab lagu saaqay, reaction - xasiloon-acidic, xoqe acids organic.

Qashin wakiil inta badan fiber, fareeshka ah iyo lignin, ay dareen-celin - acidic, laakiin xabagta calcium iyo waxa ku jira aan ku filnayn. Waxaa giirte inta badan fangaska, oo waxaa kor u formation of acids fulvic xoqe. Intaa waxaa dheer, lakabyada sare ee carrada qaawan si xooggan lagu dhaqo baxay xeryahooda L iyo baabba 'qoto dheer oo ah macdanta ciidda. Inta lagu jiro geedi socodka, kuwaas oo ku milmi soo saarka baabbi'idda iyo, wada jir ah ula acid ah iyo biyo ayaa hoos saaray.

Sidaas darteed - taagan gooni kaabiga podzolic ama eluvial, Gudaheedana waxaa ku yar yahay element awood dhirta, oxides sesqui aluminium iyo bir, Qurub waxyabaha, laakiin wax badan oo ka mid ah quartz crystalline (SiO2) iyo silica amorphous (SiO2 • H2 O) kaas oo kaabiga this iyo ku leedahay iftiinkeeda midab cawlan, eg midabka ah ee ash.

Qaar ka mid ah walxaha in lagu maydhay ka bidhaamayaan podsolic iyo qashin, go'an yihiin hoos lakabka eluvial iyo foomka washout bidhaamayaan ah - lakabka illuvial. Waxay leedahay wax badan oo dhoobo iyo qayb ka ah Kolloidol ee oxides birta iyo aluminium, xeryahooda fosfooraska, iyo qaar ka mid ah humus. midabka ah ee kaabiga this inta badan yahay mid guduudan oo brown.

Xaddi qaar ka mid ah walxaha kaas oo lagu maydhay ka qeybaha sare ee biyaha geyi-lumo iyo profile ciidda. Sidaas daraaddeed, nuxurka geedi socodka podzolic muuqato in burburinta macdanta top of ciidda sarkhaansan yihiin falcelin acid iyo qeybiyey ku xiga ee wax soo saarka ee ay u halligmaan in profile oo dhan. Waxaa sidoo kale la rumeysan yahay in nidaamka this laga yaabaa in ay dhacaan isku dhafan oo lessivage (saarista lakab ciid sare ee Qurub dhoobada aan baabbi'iyey dhismeedka).

profile ciidda podzolic leeyihiin qaab-dhismeedka soo socda: A 2 O + A + B + C

O A - qashin ah, oo dhumucdiisuna waxay a of 3 - 5 sentimitir, taas oo ka kooban ku harta qayb giirte iyo undecomposed ajada, planus, cirbadaha, oo gogo 'oo jilif iyo wixii la mid.

A 2 - waa eluvial ama lakabka podzolic ahaa anfac badan ama caddaan-cawlan, isagoo qaab jilicsan heerarka-platy ama wadajir structureless, oo dhumucdiisuna waxay of wax ka badan rubuc ka mid ah mitir.

B - waa illuvial lakabka cas-brown ama buni cufan, isagoo qaab prismatic ama blocky, oo dhumucdiisuna waxay a of hal mitir, waxa loo qaybin karaa subhorizons - B 1, 2 B, iyo wixii la mid ah.

C - waa dhagax weyn waalidka waxaa wakiil dhoobada inta badan carbonate-free ama la gudboon. At soohdinta reer qashin iyo jid toosan podsolic qoondeeyo kartaa lakabka A 0 A 1, oo dhumucdiisuna waxay a of 2 - 3 cm, oo ka kooban hoose iyo sidoo of qashin giirte ama midab walxaha a humus macdanta lakabka sare profile A 1 A 2.

ciidda podzolic on guryaha allifey oo loogu talagalay dalagga waxa on sii kordhaya. kaabiga humus The jirto ficil reaction lahayn - si xoog leh acidic (pH = 4.0-4.5), awood nuugista ay - 3 ilaa 15 mg • Equatorial / 100 garaam oo ciidda, taas oo waa wax yar. Intaa waxaa dheer, podzolic yar cokan saldhig - ka 30 ilaa 40%.

Nafaqooyinka sida fosfooraska, potassium, nitrogen iyo kuwa kale oo sidoo kale waa yar yahay. ciidda Podsolic structureless, dabaalan foomka roobka dabadiis oo kibis ah oo ku filan cufan ka dib markii lagu qalajiyo. Waxaas oo dhan waxay saamayn xun ku dhirta.

Wixii beerista ee dalka sida, waa in lagu limed, ka dhigi heerarka sare ee labada Bacriminta organic iyo macdanta. Beerihiisay u carradu podzolic u baahan qoto dheer ah 24 sentimitir oo ay hubiyaan in daaweynta sida ay xeerarka.
