M.R. Carter, in Encyclopedia of Soils in the Environment, Introduction. Conservation tillage (CT) is an umbrella or generic term used to describe tillage systems that have the potential to conserve soil and water by reducing their loss relative to some form of conventional tillage.

Precise definitions of conservation tillage are only possible within the context of known crop species. Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning.

Examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and es of draft-animal-powered or mechanized work include ploughing (overturning with moldboards or chiseling with chisel shanks.

Tillage systems are often classified by the amount of surface residue left on the soil surface. Conservation tillage systems leave more than 30% of the soil surface covered with crop residue.

This amount of surface residue cover is considered to be at a level where erosion is significantly reduced (see figure ). Of course, this residue.

Conservation Tillage and Environmental Issues by David L. Schertz, National Agronomist, Soil Conservation Service, USDA, Washington, DC The research and development theof conservation tillage began in the early 's in reducethe United States but did not gain popularity until mid's.

Land users began accepting this practice order to. Conservation Tillage - Equipment 94 Specific Outcomes: At the end of this session students will: • Have an understanding of farm equipment and that will enable the employee to relate to the client.

• Understand the effects of equipment used in conventional tillage. • Be able to offer alternatives that will improve the resource concern. A sociological study of changing farming methods, Conservation Tillage and Cropping Innovation investigates those techniques that have gradually continued to replace the plow culture.

With thorough documentation of the conservation tillage and cropping revolution, this book features chapters on: The Social Construction of Innovative Networks Cited by: Conservation tillage practices tend to increase the tortuosity of surface runoff path and increase infiltration time.

Conservation tillage systems dominate regions of the country where farming is practiced on sloping lands, soil texture is conducive to crusting and erosive rains.

Conservation tillage (CT) is a key tool in sustainable production systems throughout the world. It has been particularly effective at sustaining crop production in semi-arid rain-fed regions. Wherever potential evaporation exceeds precipitation during most months of the year, proper application of water-conserving CT technology is critical.

Agriculture and the Environment. From help in mitigating Assessing the potential for conservation tillage book losses in runoff and drainage, to offering nutrient management workshops and strip tillage-demonstrations, Water Resource Center researchers work closely with farmers throughout the state on practices to improve the quality and quantity of Minnesota’s water supply.

conservation-tillage farming crop cultivation in which the soil is disturbed little (minimum-tillage farming) or nat at all (no-till farming) to reduce soil erosion, lower labour costs, and save energy. Conservation tillage practices are grouped into three types: no-till, ridge- till, and mulch-till.

Keep in mind that no one conservation tillage method is best for all fields. Decisions should be based on the severity of the erosion problem, soil type, crop rotation, latitude, available equipment, and management skills.

The Natural Resource Conservation Service, US Department of Agriculture, defines conservation tillage as “any tillage and planting system in which at least 30 percent of the soil surface is covered by plant residue after planting to reduce soil erosion by water, or where soil erosion by wind is the primary concern of at least 1, pounds per.

Conservation tillage is part of a system of crop production designed to minimize soil disturbance, maintain previous crop residue on or near the soil surface and minimize the number of field operations.

Conservation tillage systems (described below) can be an important part of a sustainable agricultural system, in that they can be used to decrease soil erosion losses ordinarily associated with typical US agricultural practices.

It is important to remember that anything that is done to decrease erosion losses also decreases the need to add as much fertilizer. conservation crop rotation, in integrated system, conservation tillage plays an important role in improving both runoff to streams, rivers, and lakes as well as water that finds its way into aquifers).

Accelerated erosion as a result of human and animal activities, including tillage is a major environmental and economic problem throughout the world. The severity of soil erosion and changes on soil as a whole is a result of a combination of factors which include tillage and management practices (Moore et al, ).

Soil Sci Soc Am by: Conservation Tillage The objective of conservation tillage is to provide a means of profitable crop production while minimizing soil ero-sion due to wind and/or water. The emphasis is on soil conservation, but conserving soil moisture, energy, labor, and even equipment provides additional benefits.

Minimum tillage farming involves some disturbance of the soil, but uses tillage equipment that leaves much of the vegetative cover or crop residue on the surface. Funding Source. The State of Maryland offers an income tax subtraction modification to help farmers offset costs associated with buying certain types of conservation tillage equipment.

Together with cover crops, conservation tillage has the potential to reduce erosion, increase rainfall infiltration, reduce subsurface compaction, and maximize soil organic carbon accumulation, which positively affects many soil physical and chemical properties.

There are several good sources of information on cultural methods, equipment, and managementfor designing a sustainable no-till cropping system. Conservation Tillage Conservation tillage, or "no-till" farming, has become increasingly popular as a way to reduce soil erosion, increase organic matter, and enhance soil physical properties.

The effect of no-till versus conventional production practices on soil ecology was studied as the initial experiment on the CEFS Conservation. The objective of this study is to reach a judgment of the amount of U.S. cropland likely to be in some form of conservation tillage in The future spread of conservation tillage will be conditioned primarily by farmers' perceptions of its economic advantages relative to conventional tillage and by the society's perceptions of its advantages and disadvantages with respect to the environment.

Conservation tillage reduces water and wind erosion by at least 40 to 50 percent. This practice also improves organic matter content near the surface of the soil. As with all things, conservation tillage has its advantages and disadvantages when com-pared to conventional tillage.

Soil prepared by conservation tillage tends to be cooler File Size: 2MB. Conservation tillage also reduces erosion and improves the soil’s ability to absorb water and hold it. As a result, less topsoil is lost. On irrigated cropland, less energy is required for watering because plant residue can help to hold moisture in the soil for crops to use.It contributes to environmental conservation as well as to enhanced and sustained agricultural production (FAO, ).

No-tillage, direct sowing, direct drilling and conservation tillage all aim to achieve conservation by:   Collembola are soil dwelling organisms that provide important ecosystem services within soils.
