Definicija: Distinctive successive layers of soil produced by internal redistribution processes. Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and/or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron/aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil.

Horizont B ali podtalje je področje usedlin, obogaten je z glinastimi minerali in železovimi ali aluminijevimi oksidi iz povrhnjice. Horizont C ali matični substrat je izvorna snov prsti, delno je lahko iz zdrobljenih skal, ledeniških ali naplavin ali iz zgodnejših prsti. Pri nekaterih tleh horizonta B ni.

Definicija: Water stored in soils.

Definicija: Voda, ki jo zadržuje prst.

Definicija: Soil impaired as a consequence of human activity. A study financed by UNEP, reporting in 1992, found that about 10,5% of the world's vegetative surface had been seriously damaged by human activity since 1945. The study found that much of the damage had been masked by a general rise in global agricultural productivity resulting from expanded irrigation, better plant varieties, and greater use of production inputs, such as fertilizers and pesticides. More than 1/3 of the damaged land was in Asia, almost 1/3 in Africa, and 1/4 in Central America. Some land had been damaged beyond restoration. The greatest sources of soil degradation were overgrazing, unsuitable agricultural practices, and deforestation.

Definicija: Prst, ki je poslabšana zaradi človeških dejavnosti. Raziskava iz leta 1992, ki jo je plačal UNEP, je odkrila, da je od leta 1945 približno 10,5 % svetovne vegetativne površine resno poškodovane zaradi človeških dejavnosti. Raziskava je ugotovila, da je bilo veliko škode prikrite s splošnim dvigom svetovne poljedeljske proizvodnje, ki je rezultat namakanja, boljših različic rastlin in večje uporabe gnojil in pesticidov. Več kot ena tretjina poškodovane zemlje je v Aziji, skoraj tretjina v Afriki in četrtina v Srednji Ameriki. Nekaj zemlje je tako poškodovane, da obnova ni mogoča. Največji vzroki poslabšanja prsti so prekomerna paša, neprimerni poljedeljski postopki in krčenje gozdov.

Definicija: The major processes in soils are gains, losses, transfers, and transformations of organic matter, soluble salts, carbonates, silicate clay minerals, sesquioxides, and silica. Gains consist normally of additions of organic matter, and of oxygen and water through oxidation and hydration, but in some sites slow continuous additions of new mineral materials take place at the surface or soluble materials are deposited from groundwater. Losses are chiefly of materials dissolved or suspended in water percolating through the profile or running off the surface.

Definicija: Glavni procesi v prsti so prirast, izguba, prenos in preobrazba organskih snovi, topnih soli, karbonatov, silikatnih glinastih mineralov, oksidov in kremena. Prirast se ponavadi sestoji iz dodatnih organskih snovi ter iz kisika in vode z oksidacijo in hidracijo.

Definicija: mineralna sedimentna kamnina

Definicija: physical material at the surface of the earth. Land covers include grass, asphalt, trees, bare ground, water, etc. Land cover is distinct from land use despite the two terms often being used interchangeably.

Definicija: The main soil function is participation in the material transformation and migrating processes occurring in the natural environment on which the functioning of ecosystems depends. The most active participants in the occurring processes are microorganisms and invertebrates, whose activity, different variety, complex structure, and abundance accurately reflect the soil type and its characteristics: so they are important indicators of ecological stability. The variety of soil organisms determine its self-regulatory and self-cleaning capacity.

Definicija: The removal of water or any soluble constituents from the soil. Leaching often occurs with soil constituents such as nitrate fertilizers with the result that nitrates end up in potable waters.

Definicija: Odstranjevanje vode ali drugih topnih sestavin iz prsti. Pogosto je izpiranje sestavnih delov prsti, kot so dušikova gnojila, posledica so nitrati v pitni vodi.

Definicija: 1) Water stored in soils. 2) One of the most important elements involved in pedological processes and plant growth. There are three basic forms: a) water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. b) Water forming thicker films and occupying the smaller pore spaces is termed capillary water. Since it is held against the force of gravity it is permanently available for plant growth and it is this type of soil water which contains plant nutrients in solution. c) Water in excess of hygroscopic and capillary water is termed gravitational water, which is of a transitory nature because it flows away under the influence of gravity. When the excess has drained away the amount of water retained in the soil is termed its field capacity, when some of its pore spaces are still free of water.

Definicija: 1. Vsebnost vode v prsti. 2. Eden najpomembnejših elementov v pedoloških postopkih in rasti rastlin. Obstajajo tri glavne oblike: a) hidroskopska voda (cedilna voda, perkolat), ki se z molekularno privlačnostjo v tankih prevlekah prilepi na površje prstenih delcev, do te vode rastline ne pridejo; b) kapilarna voda oblikuje debelejše prevleke in se nabira v majhnih porah. V nasprotju s težnostno silo jo prst obdrži in je dostopna rastlinam, ta oblika vode ima raztopljena hranila za rastline; c) gravitacijska voda je presežek hidroskopske in kapilarne vode, je prehodne narave, ker teče pod vplivi težnostne sile. Ko presežek odteče, je količina vode, ki je ostala v prsti področna prostornina, saj so nekatere pore še vedno prazne.

Definicija: Organisms which live in the soil.

Definicija: Organizmi, ki živijo v prsti.

Definicija: Measurement of the quantity of mineral salts found in a soil. Many semi-arid and arid areas are naturally salty. By definition they are areas of substantial water deficit where evapotranspiration exceeds precipitation. Thus, whereas in humid areas there is sufficient water to percolate through the soil and to leach soluble materials from the soil and the rocks into the rivers and hence into the sea, in deserts this is not the case. Salts therefore tend to accumulate.

Definicija: Količina mineralnih soli v prsti. Veliko polsuhih in suhih področij je naravno slanih. Območja s trajnim pomanjkanjem vode so tam, kjer je izhlapevanje večje kot je količina padavin. Medtem ko je v vlažnih področjih dovolj vode, da pronica skozi prst in izpira topne snovi iz prsti in skal v reke in nato v morje, je v puščavah drugače, sol se tam nabira.

Definicija: Compaction involves the close-packing of the individual grains mainly by the elimination of pore-space and expulsion of entrapped water; this is normally brought about by the weight of the overlying sediments.
