National Soil Erosion Research Laboratory The National Soil Erosion Research Laboratory (NSERL) of the United States Department of Agriculture Agricultural Research Service is the focal point for the U.S. Government's national research program in soil erosion by water. This modern facility houses over twenty scientists and support staff , and is equipped with a large indoor hydraulics laboratory, portable rainfall simulators for field experimentation, as well as extensive computer equipment. Major program thrusts of the NSERL include fundamental erosion process research, erosion control research, and delivery of improved erosion prediction technology. The mission of the NSERL is to develop the knowledge and technology needed by land users to conserve soil for future generations. The NSERL is located on the campus of Purdue University (building labeled SOIL in south center of map) in West Lafayette, Indiana Listen to an audio welcome to the NSERL, from former Director John M.

Agriculture is the process of producing food , feed, fiber and other desired products by cultivation of certain plants and the raising of domesticated animals . Agriculture is also known as farming Table of contents 1 Overview 2 History 3 Policy 4 Methods ... edit Overview Agriculture includes both subsistence agriculture , which is producing enough food to meet the needs of the farmer and family (but no more), and also (almost universally in the "developed" nations and increasingly so in other areas) the production of financial income from cultivation of the land or commercial raising of animals ( animal husbandry ). Agriculture is the practice the study of these disciplines is called agricultural science Increasingly, besides food for humans and animal feeds , agriculture produces goods such as cut flowers, ornamental and nursery plants, fertilizers animal hides leather , industrial chemicals ( starch ethanol , and plastics fibers cotton wool ... hemp , and flax ), fuels ( methane biodiesel biomass ), and both legal and illegal drugs biopharmaceuticals tobacco marijuana ... Genetically engineered plants and animals produce specialty drugs.

- Browse By : - LETTER TOPIC BY KEYWORD: Soil is truly a cradle of life. -"Cradle of Life," in Ohio's Natural Heritage Nicholas Holowaychuk, 1979 Soils are formed through Natural Factors acting on Parent Material. Parent material Parent material is made up of the rock and mineral material exposed at the earth's surface. In Ohio there are three main groups of parent material: Lake sediments left by ancient lakes; Solid bedrock; Glacial till - the rubble that Ice Age glaciers left behind more than 10,000 years ago. In Ohio there are more than 100 different specific kinds of parent materials. Natural Factors Climate and weather. For example freezing and thawing will break rock into small pieces. Plants and animals. Decayed animals and plants leave organic material that becomes part of soils. Conditions of ground slope and water drainage. For example, water running down hill wears rock and mixes parent materials. Time. It takes time for the other natural factors to do their work. The result of natural factors working on parent materials is that Ohio has a great variety of specific soils. Soil Regions This map shows locations of the major soil regions in Ohio.

Describing Australian Soils The GRDC has decided to use the terminology of the Australian Soil Classification A list of the ASC soil type names, together with a brief description and links to other common descriptors, is provided below. Calcarosols These soils contain calcium carbonate (as limestone, calcrete or other forms) as soft or hard fragments or as a solid layer. They occur in areas with low rainfall. Limitations for agriculture include shallow depth, low water retention and wind erosion on the sandier forms. High salinity, alkalinity and sodicity may also be a problem. Soil fertility deficiencies are widespread.  Also known as solonised brown soils; grey-brown and red calcareous soils; calcareous sands. Hypocalcic Calcarosol Supracalcic Calcarosol Hypercalcic Calcarosol Calcic Calcarosol Chromosols Also know as non-calcic brown soils; some red-brown earths and a range of podzolic soils; some ironstone gravel soils. Red Chromosol Brown Chromosol Yellow Chromosol Grey Chromosol Dermosols Dermosols occur as moderately deep and well-drained soils in the wetter areas of eastern Australia. They may be strongly acid in the high rainfall areas or highly alkaline if they contain calcium carbonate. Dermosols support a wide range of land uses, and cereal crops, especially wheat, are commonly grown on the more fertile examples.Â

American Journal of Alternative Agriculture AJAA Index Virtual Library Magazine Rack Search ... Join the Ecological Solutions Roundtable Restoring the productivity of marginal soils with organic amendments Sharon B. Hornick and James F. Parr Abstract Introduction Regular additions of organic materials such as animal manures and crop residues are of utmost importance in maintaining the tilth, fertility and productivity of agricultural soils, protecting them from wind and water erosion, and preventing nutrient losses through runoff and leaching. These materials have predictable beneficial effects on soil physical properties such as increased water-holding capacity, soil aggregation, soil aeration and permeability, and decreased soil crusting and bulk density (USDA, 1957; 1978). Failure to recycle organic wastes and residues, intensive row crop production, and lack of sod-based crop rotations can result in extensive soil degradation and a decline in productivity due to excessive soil erosion and loss of fertility. The continuing desertification of Sub-Saharan Africa and the dustbowl of the central U.S. Great Plains in the 1930's can be attributed largely to improper farming methods that neglected the importance of soil organic master in crop production. When organic materials, such as compost, animal manures, crop residues and sewage sludges are used as the primary sources of plant nutrients, the management system has often been referred to as "organic farming" (USDA, 1980). More recently, the terms alternative, regenerative. low-input, and sustainable have been used to describe farming systems that recycle available on-farm organic resources and sometimes off-farm materials such as municipal wastes, to maintain or improve soil productivity.

Agriculture and food PAGE Agroecosystems: Carbon services Agroecosystems Scorecard Pilot Analysis of Global Ecosystems (PAGE) Agricultural ecosystems analysis Carbon, an essential component of all life forms, is constantly being absorbed, released, and recycled by a range of natural and human-induced biological and chemical processes. Agriculture both influences and is affected by this global cycle. Of particular importance is the process of photosynthesis in which plants absorb atmospheric carbon as they grow and convert it into biomass. Furthermore, when plant residues and roots decompose, the carbon they contain is transformed primarily into soil organic matter and carbon based gases. One product, soil organic matter, is particularly critical in conditioning soil quality and, hence, the capacity of agroecosystems to provide a number of agricultural and environmental goods and services. The cumulative impact of human activities, including agriculture, has been to significantly increase the atmospheric concentration of the so-called greenhouse gases, such as carbon dioxide (CO2) and methane (CH4). Higher concentrations of greenhouse gases have induced (or accelerated) the process of global warming the gradual increase in the earth's surface temperature that is also having an observable impact on the amount, variability, and spatial pattern of precipitation and, through such changes, on agricultural production.
