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

* Soil Science – study of soil as a natural resource on the surface of the earth including soil formation, classification and mapping ; physical, chemical, biological, and fertility properties of soils ; and these properties in relation to the use and management of soils.

Soil science is the study of soil as a natural resource on the surface of the earth including soil formation, classification and mapping ; physical, chemical, biological, and fertility properties of soils ; and these properties in relation to the use and management of soils.

* Soil management

* Soil fertility / Nutrient management

Soil type, minimum annual temperature, and rainfall are important factors in pasture management.

In the United States, federal programs administered through local Soil and Water Conservation Districts provide technical assistance and partial funding to farmers who wish to implement management practices to conserve soil and limit erosion.

** Soil conservation, management strategies for prevention of soil being eroded from the earth ’ s surface or becoming chemically altered

Soil conservation is a set of management strategies for prevention of soil being eroded from the Earth ’ s surface or becoming chemically altered by overuse, acidification, salinization or other chemical soil contamination.

Soil management, or direct human interaction with the soil, is another mechanism of anthropogenic change studied by historical ecologists.

Soil management can take place through rearranging soils, altering drainage patterns, and building large earthen formations.

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

) and agriculture related service industries including several diversified fruit packing and shipping operations, wineries, agriculture management and consulting, veterinarian, and USDA Soil Conservation Service.

Originally developed as a legend to the Soil Map of the World, the classification was applied by United Nations sponsored projects.

Upcoming projects include collaborations with ex-New Order member Peter Hook's Freebass, a guest spot on Joaquin Phoenix's rap album and Italian ghetto-tech duo The Crookers appear in 2009 as well as credit of Producer for new London band Hatcham Social, working with them on their double A single Til The Dawn / Penelope ( Under My Hat ) and debut album-You Dig The Tunnel And I'll Hide The Soil released in March 2009.

Soil conversation and erosion control were of primary importance for the in the Buckeye and Boxelder drainage projects.

With Absu still on hold, Proscriptor continued to work on other projects including Equimanthorn ( with Equitant and members of The Soil Bleeds Black, dark ambient music ), Proscriptor ( his own project of neo-folk / classic rock fused music ), and Starchaser Network ( with Equitant and Victorious ; electronic art / rock band ).

Soil scientists have raised concerns about how to preserve soil and arable land in a world with a growing population, possible future water crisis, increasing per capita food consumption, and land degradation.

The Soil Stradivarius appears in the video game Fallout 3 as an item to be recovered from Vault 92, an underground bunker created to preserve the musical arts after a nuclear holocaust.

Soil disturbance like tilling increase decomposition by increasing the amount of oxygen in the soil and by exposing new organic matter to soil microbes.

Soil Erosion and Cill prevent the disruption and detachment of soil aggregates that cause macrospores to block, infiltration to decline, and runoff to increase.

19 ( 2 ), 2001, p. 81 ‐ 83 ) shows that biointensive methods can enable small ‐ scale farms and farmers to significantly increase food production and income, utilize predominantly local, renewable resources and decrease expense and energy inputs while building fertile topsoil at a rate 60 times faster than in nature ( Worldwide Loss of Soil – and a Possible Solution Ecology Action, 1996 ).

Soil amendments can also greatly increase the cation exchange capacity of soils.

Soil compaction also affects the permeability of the soil to water, and hence the amount of water that flows away as runoff.

Soil moisture is a general term describing the amount of water present in the vadose zone, or unsaturated portion of soil below ground.

Ecology / Conservation, often referred to as " Econ ," teaches a large amount of merit badges including Astronomy, Bird Study, Environmental Science, Fish and Wildlife Management, Forestry, Mammal Study, Nature, Soil and Water Conservation and Weather.

Soil tests revealed petroleum and lead ; the lead was 300 times the amount of safe concentration for a homeowner.

Soil organisms use any nitrogen to break down carbon sources, making N unavailable to plants.

* Patrick Holden, ex-Director of Soil Association, presents Week In, Week Out for BBC Wales examining the implications of a carbon constrained world on agriculture

* Soil organic carbon ( SOC ), see Soil carbon

Soil fertility limits carbon sequestration by forest ecosystems in a CO < sub > 2 </ sub >- enriched atmosphere.

Soil containing high levels of organic materials are often more resistant to erosion, because the organic materials coagulate soil colloids and create a stronger, more stable soil structure.

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 a natural body consisting of layers ( soil horizons ) that are primarily composed of minerals which differ from their parent materials in their texture, structure, consistency, colour, chemical, biological and other characteristics.

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

Soil colloidal particles ( clay and humus ) behave as a repository of nutrients and moisture, and buffer the variations of soil solution ions.

Soil pH, a measure of the hydrogen ion ( acid-forming ) soil reactivity, is a function of the soil materials, precipitation level, and plant root behavior.

Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological, and anthropogenic processes on soil parent material.

Soil texture is determined by the relative proportion of the three kinds of soil particles, called soil " separates ": sand, silt, and clay.

Soil density, particularly bulk density, is a measure of soil compaction.

Soil porosity consists of the part of the soil volume occupied by air and water.

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.

Soil texture affects soil behaviour, in particular its retention capacity for nutrients and water.

Soil components larger than 2. 0 mm are classed as rock and gravel and are removed before determining the percentages of the remaining components and the texture class of the soil, but are included in the name.

Soil steam sterilization involves injecting steam into contaminated soil in order to kill subterranean plant parts.

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

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.
