Organic matter is important for soil health and crop productivity. While an indicator of soil quality, a lot of organic matter is in extremely stable forms, and the nutrients in such forms are difficult for plants to use. The active, labile fraction, however, is a modest but important part of the organic matter. "The labile fraction is small — usually less than 20 or even 10 percent, depending on how you define it," explains Steve Culman, lead author of a study published online Feb....

Understanding Travel Patterns Of Microbes Blowing In The Wind
2013-02-07 09:32:18

U.S. Department of Agriculture (USDA) With help from a wind tunnel and the latest DNA technology, U.S. Department of Agriculture (USDA) scientists are shedding light on the travel patterns of microbes in soils carried off by strong winds. The work has implications for soil health and could lead to management practices that minimize the damage to soils caused by wind erosion. Wind erosion is an emerging issue in soil conservation efforts. Agricultural Research Service (ARS) scientists...

Development Of Organic Rice Farming Might Benefit From New Species Of Semi-aquatic Freshwater Earthworms
2013-02-07 09:19:26

Pensoft Publishers The semi-aquatic earthworms in the genus Glyphidrilus are somewhat unfamiliar species that live between the terrestrial and freshwater ecosystems of rivers, streams, canals, ponds, swamps and paddy systems. Remarkably, each species is endemic to a single water basin, carrying its own signature of evolution from their common origin. A study describing ten newly discovered species of the genus has been published in the open access journal ZooKeys. In Thailand, the...

New Protocol Developed For Measuring Soil Organic Carbon Sequestration
2013-02-01 14:39:04

University of Illinois College of Agricultural, Consumer and Environmental Sciences Increased levels of greenhouse gases, particularly carbon dioxide (CO2), have been associated with the burning of fossil fuels, deforestation, cultivation of grasslands, drainage of the land, and land use changes. Concerns about long-term shifts in climate patterns have led scientists to measure soil organic carbon (SOC) in agricultural landscapes and to develop methods to evaluate how changes in tillage...

Afforestation, planting trees in an area where there have previously been no trees, can reduce the effect of climate change by cooling temperate regions finds a study in BioMed Central's open access journal Carbon Balance and Management. Afforestation would lead to cooler and wetter summers by the end of this century. Without check climate change is projected to lead to summer droughts and winter floods across Europe. Using REMO, the regional climate model of the Max Planck Institute for...

Hailstones Full Of Bacteria And Organic Chemicals Says Study
2013-01-24 14:35:40

Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the online journal PLOS ONE, there is a rich diversity of microbial life and chemicals in the ephemeral habitat of a storm cloud. A Danish research team at Aarhus University analyzed hailstones recovered after a storm in May 2009 and found that they carried several species of bacteria typically found on plants as well as nearly 3,000 different compounds commonly found in soil. The hailstones had...

There Is A Limit For How Long Plants Can Adapt To Drought
2013-01-23 13:50:15

University of Arizona Plants can adapt their demand for water depending on how much is available - However, this resilience has a limit, and prolonged drought conditions threaten the survival of plant communities, especially in more arid areas Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing...

Sheet Mulching
2013-08-05 12:36:35

Sheet mulching, or lasagna gardening, is the process of turning barren ground into a more nourishing garden without digging. It is a layered system that can be used for a yard garden or a topical box garden. Starting at the bottom is a weed proof barrier, like newspaper or cardboard. On top of that is a twelve-inch layer of compost or mulch material such as old clothes, yard clippings, and manure, which provides for nutrient rich soil. Weed-free soil is added prior to planting the desired...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Land Degradation
2013-04-02 09:20:15

Land degradation is a process in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting on the land. It is also the gradual destruction or reduction of the quality and quantity of human activities, animal activities or natural means. It is viewed as any change or disturbance to the land perceived to be deleterious or unwanted. Natural hazards are not included in the causes; however, human activities can indirectly affect...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...
