Soil steaming is an effective alternative to chemicals in agriculture.

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.

Soil salinity can be reduced by leaching soluble salts out of soil with excess irrigation water.

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 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.

Soil erosion ( especially from agricultural activity ) is considered to be the leading global cause of diffuse water pollution, due to the effects of the excess sediments flowing into the world's waterways.

Though he did vote against the admission of Missouri as a slave state, and though he would be the nominated presidential candidate of the Free Soil Party, an anti-slavery political party, in 1848, there was no ambiguity in his position on the abolition of slavery during his term of office.

Soil is commonly referred to as " earth " or " dirt "; technically, the term " dirt " should be restricted to displaced soil.

Soil is said to be formed when organic matter has accumulated, and colloids washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum.

Soil is said to be formed when detectable layers of clays, organic colloids, carbonates, or soluble salts have been moved downward.

Ribosomal RNA gene sequencing of soil suggests that there may be a fourth subphylum of Ascomycota ( termed Soil Clone Group I or SCGI ), that has not been described in cultures or based on fruiting bodies.

The " Free Soil " Party of 1848 – 52 and the new Republican Party after 1854 demanded that the new lands opening up in the west be made available to independent farmers, rather than wealthy planters who would develop it with slaves, and force yeomen farmers onto marginal lands.

Soil degradation may also be viewed as any change or disturbance to the soil perceived to be deleterious or undesirable.

* Soil classification systems cannot be based entirely on perceptions of genesis, however, because genetic processes are seldom observed and because pedogenic processes change over time.

The current village is actually the second settlement in Mason County to be named Free Soil.

Cedar Soil Conservation Office should be given credit here as they assisted in

Soil pH should be tested, and corrected if needed, because calcium deficiency is often associated with low pH.

The most commonly used model for predicting soil loss from water erosion is the Universal Soil Loss Equation ( USLE ), which estimates the average annual soil loss as:

Soil is contaminated through particulate accumulation from lead in pipes, lead paint and residual emissions from leaded gasoline that was used before the Environment Protection Agency issue the regulation around 1980.

Soil type s by clay, silt and sand composition as used by the United States Department of Agriculture | USDAIron-rich soil near Paint Pots in Kootenay National Park, Canada The mineral components of soil, sand, silt, and clay determine a soil's texture.

* Unified Soil Classification System, a soil classification system used in engineering and geology

Menuhin used a number of famous violins including the Giovanni Bussetto 1680, the Giovanni Grancino 1695, the Guarneri filius Andrea 1703, the Soil Stradivarius, the Prince Khevenhüller 1733 Stradivari, the Guarneri del Gesù 1739, and the Lord Wilton 1742 Guarneri del Gesù.

It used the slogan " Free Soil, Free Men, and Frémont " to crusade for free farms ( homesteads ) and against the Slave Power.

The headquarters of the Soil Association used to be at the nearby Haughley Green in Suffolk.

It used to occupy Walnutree Manor, former headquarters of the Soil Association.

Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils.

In the US and other countries, the Unified Soil Classification System ( USCS ) is often used for soil classification.

Two of the more widely used methods in North America are the Revised Universal Soil Loss Equation ( RUSLE ) and Water Erosion Prediction Project erosion model ( WEPP ).

Also, it was found that the Afton Soil ( paleosol ), which was used define the Aftonian interglacial, is buried by a younger glacial till that was considered to be a " type Nebraskan " glacial till as well as having developed in an older glacial till that was considered to be a " type Nebraskan " glacial till.

Soil, sand, or bark chippings can be used as substrate.

Soil conditioners can be used to improve poor soils, or to rebuild soils which have been damaged by improper management.

Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well.
