| lurzoruaren kutsadura |
soil pollution (Modifications of soil features or, more generally, of its chemical and biological balance, caused by the discharge of polluting substances) |
|
| lurzoruaren kutsatzaile |
soil pollutant (Solid, liquid and gaseous substances that detrimentally alter the natural condition of the soil) |
|
| lurzoruaren lixibiazio |
soil leaching (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) |
|
| lurzoruaren mekanika |
soil mechanics (The study of the physical properties of soil, especially those properties that affect its ability to bear weight such as water content, density, strength, etc.) |
|
| lurzoruaren mineralogia |
soil mineralogy (Study of the formation, occurrence, properties, composition, and classification of the minerals present in the soil) |
|
| lurzoruaren narriadura |
soil degradation (Soil may deteriorate either by physical movement of soil particles from a given site or by depletion of the water-soluble elements in the soil which contribute to the nourishment of crop, plants, grasses, trees, and other economically usable vegetation. The physical movement generally is referred to as erosion. Wind, water, glacial ice, animals and tools in use may be agents of erosion) |
|
| lurzoruaren ongarritze |
soil fertilisation (The application of any organic or inorganic material of natural or synthetic origins to a soil to supply one or more elements essential to the growth of plants) |
|
| lurzoruaren poluitzaile |
soil pollutant (Solid, liquid and gaseous substances that detrimentally alter the natural condition of the soil) |
|
| lurzoruaren profil |
soil profile (A vertical section of a soil, showing horizons and parent material) |
|
| lurzoruaren subsidentzia |
soil subsidence (A sinking down of a part of the earth's crust, generally due to underground excavations) |
|
| lurzoruaren trinkotze |
soil compaction (An increase in bulk density (mass per unit volume) and a decrease in soil porosity resulting from applied loads, vibration, or pressure. More compacted soils (or other materials) can support greater loads (load-bearing capacity). Bulk density can be increased by controlling the moisture content, compaction forces and treatment procedures, as well as by manipulating the type of material being compacted) |
|
| lurzoruaren zientzia |
soil science (The study of the properties, occurrence, and management of soil as a natural resource. Generally it includes the chemistry, microbiology, physics, morphology, and mineralogy of soils, as well as their genesis and classification) |
|
| lurzoruari egindako kalte |
soil damage (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) |
|
| lurzoruko atmosfera |
soil air (The air and other gases in spaces in the soil; specifically that which is found within the zone of aeration. Also known as soil atmosphere) |
|
| lurzoruko baliabide |
soil resource (No definition needed) |
|
| lurzoruko hezetasun |
soil moisture (1. Water stored in soils. 2. One of the most important elements involved in pedological processes and plant growth. There are three basic forms: 1. water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. 2. 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. 3. 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) |
|
| lurzoruko hezetasunaren erregimen |
soil moisture regime (The water regime of the soil is determined by the physical properties and arrangement of the soil particles. The pores in a soil determine its water-retention characteristics. When all the pores are full of water, the soil is said to be saturated) |
|
| lurzoruko organismo |
soil organism (Organisms which live in the soil) |
|
| lurzoruko prozesu |
soil process (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) |
