Sebopeho sa mobu

tlhophiso mobu e thehiloe molao-motheo oa ho hlahloba mobu le ikemetseng mofuta khethehileng ea 'mele, e leng e ka beha ka par, e le liminerale, limela le liphoofolo. mokhoa ona oa ho tlhophiso e thehiloeng thepa le litšobotsi tsa tsimoloho ea mobu. Karolo ea pele ea mobu ka motheo oa liphatsa tsa lefutso tsa Dokuchaev

The letšoao ka sehloohong tseo ka tsona ke karohano - ke mofuta oa mobu. Thupelong ena tlhophiso bolela mobu kopana tlasa maemo a tšoanang le ka thepa ea tšoanang le sebopeho.

Har'a tse tummeng ka ho fetisisa eo re ka khetholla mefuta e latelang ea mobu: podzolic, krasnozems, mobu e ntšo, mokhoabo oo letsoai, 'me ba bang. Mefuta mobu aroloa ho eketsehileng subtypes ka genera fetoha mefuta e le mefuta e sa tsoaneng le ho dihlopha.

Subtypes bontša litšobotsi tse ikhethang tsa profil mobu. E phetha karolo e ka boemo ba leholimo kontinenteng le maemo a mogote ea libaka bolokolohi. Subtypes ke intermediates pakeng tsa mefuta e sa.

karohano ka ho eketsehileng le hlaha genera le mefuta ea mobu. The genera atileng ka ho fetisisa ea mobu: tloaelehileng, alkaline, barrel-letsoai, letsoai le, quartz lehlabathe le lebitso gley, barrel carbonate, barrel-omeletseng.

Mong le e mong mosa oa mobu o na le karohano eketsehileng ka mefuta. View bontša kamoo a phatlalatsa tshebetso ya sebopeho mobu, e tloaelehileng ea le mofuta o itseng oa mobu. Ka lehlakoreng le leng, har'a mefuta e sa tsejoa 'maloa tsa mefuta e sa tsoaneng. E amana le mofuta o mong oa mobu, phapang ea tsona e feela sebopeho bona ho phetha molao feela. Tsena li akarelletsa letsopa le loam, lehlabathe le lehlabathe loam. Karolo ea bopula ho bolela hore mobu o na le ponahalo e tšoanang le botenya, empa boitsebiso boo motsoali oa ba le tšimoloho e fapaneng.

thepa e sa tšoaneng li ka kotloloho itšetlehile ka seo ba botenya ba mobu.

boleng ena e laolwang ke karo-karolelano ea likaroloana fapaneng boholo bo lekaneng mobu le e hlalosoa e le karolo e itseng. Lefufuru, majoe le majoe ba le e lumellang metsi ho kena futsanehile, eaba ba etsa tsa mangeta a lefika le thepa e ka sehloohong. Sand na thepa ea ka potlako feta metsi, kaha hoo e batlang e le bopilwe feela oa liminerale mathomo. lerōleng na le liminerale mahareng, ho ruruha ka metsi - ketsahalo ena e etsa hore thepa ea joalo mobu ka stickiness le plasticity. Mobu ka bophara sludge e akarelletsa liminerale mahareng tloha letsopa. Ba ho ruruha haholo ka metsi, ka nako eo u se ke ua hopotse ka bang ha ho na metsi, ha ho na moea.

Haeba likaroloana a fokotswa ka boholo, tshebetso qala bosa le morago ga moo e sebopeho sa liminerale mahareng - ke hydroxide ea tšepe, ea alumina, aluminosilicates le carbonates tsa Ca, K, MG.

Boholo ba likarolo phetha molao amang lik'hemik'hale bona le thepa ea 'mele. Ka hona, ka ho tseba ka bophara mobu, u ka fumana hore na thepa ea eona nang le tsona.

E ka holimo mobu brennan le mobu-eaba ba etsa majoe a eona, ho itšetlehile ka sebopeho phetha molao, arotsoe ka:

• lehlabathe:

- amana;

- hlephileng.

• Loam.
• letsopa:

- e boima;

- karolelano;

- matšoafong.

• loam:

- e boima;

- karolelano;

- matšoafong.

Fapaneng galeage tsa mobu, moo diteng tsa letsopa 'meleng, ama thepa le kang ductility. Ka litsupa lona tse sa tšoaneng, naha ka la ka bolo kapa thapo. Sena se thusa ho fumana hore na le botenya ba mobu tšimong. lebitso la lona hangata bontša sebopeho lona phetha molao feela. Ka mohlala, ho ba tloaelehileng ba batsho mobu boima loam.

Agronomic thepa ya mobu hape e itšetlehile ka botenya bona. Ho le bonolo ho sebetsana le lehlabathe loam, hobane di bitsoa matšoafong. Ho fapana le hoo, loam le letsopa fumane tsebahalang ka ho le boima ka lebaka la mathata a ka kalafo agronomic. Leha ho le joalo, ba na le ho feta limatlafatsi 'me humus, ho fapana ho ea lehlabathe le lehlabathe loam,' me ka hona nkoa e nonneng haholo.
