Environment-current issues: Soil salinity is rising.

* Soil salinity

* Soil salinity control by subsurface drainage

* Soil salinity and soil salinity control

Soil salinity is the salt content in the soil ; the process of increasing the salt content is known as salinization.

Soil salinity control involves watertable control and flushing in combination with tile drainage or another form of subsurface drainage.

Soil salinity in the lower marsh zone is fairly constant due to everyday annual tidal flow.

* Soil salinity

* Soil salinity control-rehabilitation of salinized soils

* Soil salinity, salt content of soil

The Soil Moisture & Ocean Salinity ( SMOS ) satellite's main scientific instrument Microwave Imaging Radiometer with Aperture Synthesis ( MIRAS ) uses the 1400-1427 MHz frequencies ( including 1420. 406 MHz ) to monitor the ocean surface salinity and the soil moisture of the Earth.

Soil salinity and dryland salinity are two problems degrading the environment of Australia.

* Soil salination in irrigated land requiring soil salinity control to reclaim the land

Soil salinity adversely affects the metabolism of most crops, and erosion effects usually follow vegetation failure.

Soil type, drainage, or degree of slope can make the difference between good crops and poor ones.

Soil biology and chemistry can be seriously damaged by acid rain.

Soil chemistry can be dramatically changed when base cations, such as calcium and magnesium, are leached by acid rain thereby affecting sensitive species, such as sugar maple ( Acer saccharum ).

Soil moisture can be measured in various ways ; by capacitance probe, time domain reflectometer or Tensiometer.

The Climate, Soil, and Sea provide everything that can be expected from them.

Soil fertility can sometimes be mitigated by applying the appropriate lime and organic fertilizers.

According to the Soil Association, the total copper that can be applied to organic land is 6 kg / ha / year.

Soil forms a structure filled with pore spaces and can be thought of as a mixture of solids, water, and air ( gas ).

Soil factors such as density, depth, chemistry, pH, temperature and moisture greatly affect the type of plants that can grow in a given location.

Soil building and pest population management benefits can be further utilized with different complexities of crop rotation.

From the FAO / UNESCO Soil Map of the World the following salinised areas can be derived.

Soil of the Town is generally clay loam and somewhat difficult to cultivate, but heavy crops of wheat can be grown on the land, thus giving the Town its name-Wheatfield.

* Soil analysis, such as determining pH, can help to confirm the presence of physiological disorders.

Soil steaming can be used as an ecological alternative to chemicals for soil sterilization.

Soil failure can also occur due to earthquake-induced landslides in steep terrain.

Much of this is oriented towards the use of herbicides, the majority of which may not be acceptable to the organic producer ( apart from non-synthetic substances like sulphur, which in some circumstances are accepted within Soil Association standards ) but in most cases there are manual techniques that can be used such as digging out the roots, mulching out or carefully timed cutting before seeds are able to spread.

Soil that are high in calcium minerals, for example, can be given green manure to generate a higher phosphate content in the soil, which in turn acts as a fertilizer.

Soil erosion is a process that can irreparably reduce the productive capacity of an agroecosystem.

Soil failure can occur on a slope, a slope failure or landslide, or in a flat area due to liquefaction of water-saturated sand and / or mud.

In May 2005, McKeith was given the Best Organic Businesses 2005 Consumer Education Award by the Soil Association, a British charity promoting organic food, in recognition of her work in " tackling obesity, championing healthier eating and promoting the contribution that organic fruit, vegetables and other products can make to sound nutrition.

Soil classification can be approached from the perspective of soil as a material and soil as a resource.

A number of Borsodi's texts can be found in the Social Criticism section of the Soil and Health Online Library.

Soil and sand carried through a culvert can wear away the galvanizing of a steel culvert, allowing it to corrode and eventually collapse, disrupting the road or railway above it.

Soil in good tilth is loamy, nutrient-rich soil that can also be said to be friable because optimal soil has a mixture of sand, clay and organic matter that prevents severe compaction.
