Ibice bitandukanye by'ubutaka.

A 'ubutaka butambitse' ni igipande kibangikanye nubutaka butaka imiterere yumubiri, imiti n’ibinyabuzima bitandukanye nibice biri hejuru no munsi. Horizons isobanurwa muburyo bwinshi nibintu bigaragara bigaragara, cyane cyane ibara nimiterere. Ibi birashobora gusobanurwa haba mumagambo yuzuye (ingano yubunini bwagabanijwe kubwimiterere, kurugero) no muburyo ugereranije nibikoresho bikikije, ni ukuvuga 'coarser' cyangwa 'sandier' kuruta ibizunguruka hejuru no hepfo.

Uturere twerekanwe twerekanwe nibimenyetso, bikoreshwa cyane muburyo bukurikirana. Master horizon (horizon nkuru) yerekanwa ninyuguti nkuru. Ibisobanuro, muburyo bwinyuguti nto n’ishusho, birusheho gutandukanya ibishushanyo mbonera. Hariho uburyo bwinshi butandukanye bwibimenyetso bya horizon kwisi.

Urutonde rwa Horizon

Topogarafiya y'ubutaka n'ibice byabwo bitandukanye.

Ubutaka bwinshi bufite ubuso kama, bugaragazwa ninyuguti nkuru "O" (inyuguti zishobora gutandukana bitewe na sisitemu). Ubutaka bwubutaka busanzwe butangirira kuri horizon. Niba ubutaka butunganijwe neza buturutse kubutaka bubaho, mubisanzwe byitwa B horizon. Hanze ya horizon, ariko idateye imbere cyane bita C horizon. Uburiri bukomeye burangwa cyane R. Sisitemu nyinshi kugiti cye zasobanuye uturere twinshi kuruta ibice bitanu gusa. Mubikurikira, utambitse hamwe nibice byashyizwe kurutonde cyangwa byinshi ukurikije umwanya wabyo kuva hejuru kugeza hasi mubutaka bwubutaka. Ntabwo bose baboneka mubutaka bwose.

Ubutaka bufite amateka yo kwivanga kwabantu, nkurugero binyuze mubikorwa bikomeye byubutaka cyangwa guhinga byimbitse, birashobora kubura aho bitandukaniye hafi. Iyo usuzumye ubutaka bwo mu murima, hagomba kwitabwaho geomorphologie hamwe n’imikoreshereze y’amateka, ubwo butaka bwashyizwemo, kugira ngo hamenyekane ko amazina akwiye akoreshwa kuri horizone.

Horizons

'O horizon' Inyandikorugero:Ibyingenzi

"O" bisobanura ibintu kama. Nubuso bwubuso, bwiganjemo kuba hari ibintu byinshi kama kama mubice bitandukanye byo kubora. Muri sisitemu ya Australiya, O horizon igomba gufatwa nkaho itandukanye nu gice cya imyanda y’ibabi itwikiriye ahantu henshi h’ibimera byinshi, bitarimo imyunyu ngugu y’ikirere kandi ntabwo biri mu butaka ubwabwo. O horizon irashobora kugabanywamo ibyiciro bya O1 na O2, aho O1 itambitse irimo ibintu bitarangiritse inkomoko yabyo ishobora kugaragara kubireba (urugero, ibice byamababi), naho O2 itambitse irimo imyanda kama mubyiciro bitandukanye byo kubora, inkomoko yabyo. ntabwo byoroshye kugaragara. O horizon irimo ≥ 20% karubone kama.

'P horizon'

Izi mpande nazo ni organic cyane ariko ziratandukanye na O horizon kuko zikora mubihe byuzuye amazi. Izina "P" rituruka ku izina ryabo risanzwe, peat s. Bashobora kugabanywamo P1 na P2 muburyo bumwe na O horizon. P horizon irimo ≥ 12 kugeza 18% karubone kama, bitewe nibumba.

A horizon ni igice cyo hejuru cyubutaka bwubutaka butambitse, bakunze kwita 'ubutaka'. Iki gipimo kirimo ibinyabuzima byijimye byangirika, aribyo bita "humus". Ibisobanuro bya tekiniki ya horizon birashobora gutandukana hagati ya sisitemu, ariko bikunze gusobanurwa mumagambo ugereranije nibice byimbitse. "A" utambitse dushobora kuba twijimye mu ibara kuruta ibice byimbitse kandi bikubiyemo byinshi organic organic, cyangwa birashobora kuba byoroshye ariko bikabamo bike ibumba cyangwa pedogenic oxyde s. A ni ubuso butambitse, kandi nkuko bizwi kandi nka zone igaragaramo ibikorwa byibinyabuzima. Ibinyabuzima byubutaka nka inzoka s, potworm s (enchytraeids), arthropod s, nematode, fungi, nubwoko bwinshi bwa bagiteri na archaea yibanze hano, akenshi ifatanije cyane n imizi yibihingwa. Rero, A horizon irashobora kwitwa biomantle. <ref> Wilkinson, M.T. na G.S. Humphreys. 2005. Ikinyamakuru cyo muri Ositaraliya cy’ubushakashatsi ku butaka, umurongo wa 43, pp. 767-779. A horizon irashobora kugabanywa muri A1 (umwijima, ibikorwa bya biologiya ntarengwa), A2 (paler), na A3 (inzibacyuho kuri B horizon).
