New standardized methodology developed by The Earth Partners, in a partnership with Applied Ecological Services and Brinkman & Associates, allows public agencies and other parties to document and receive marketplace credit–or other financial incentives–for improvements to soil carbon levels. Brodhead, WI (PRWEB) December 01, 2012 The Earth Partners is pleased to announce the validation of its comprehensive soil carbon quantification methodology by the Verified Carbon...

World’s Largest Artificial Watershed Has First Rain
2012-11-30 11:23:00

University of Arizona The Landscape Evolution Observatory, manmade hillsides inside the University of Arizona´s Biosphere 2, provides researchers with the first opportunity to study how water, microbes, soil and plants interact in a setting realistic enough to improve global climate models for years to come. Rain in Southern Arizona is scarce and precious to begin with, but the afternoon shower that soaked the soil 25 miles north of Tucson on Nov. 29 was unusual in several ways....

Understanding warming requires long term studies that account for real-life complexity In the northern hardwood forest, climate change is poised to reduce the viability of the maple syrup industry, spread wildlife diseases and tree pests, and change timber resources. And, according to a new BioScience paper just released by twenty-one scientists, without long-term studies at the local scale–we will be ill-prepared to predict and manage these effects. Following an exhaustive review...

A distinguished Australian scientist, the winner of an international soil science prize, has called for Australia to lead a renewed global effort to reverse the alarming degradation and contamination of the world´s food-producing soils. Professor Ravi Naidu, the Managing Director of Australia´s CRC for Contamination Assessment and Remediation of the Environment is this year´s recipient of the International Soil Science Award, presented annually by the Soil Science Society of...

Modern Soil Science Unearths Mayan Agriculture Secrets
2012-11-12 14:27:21

Lee Rannals for redOrbit.com — Your Universe Online An analysis of maize agriculture in the soils of Guatemala's Tikal National Park has revealed some ancient Maya secrets. Scientists wrote in Soil Science of America Journal that they uncovered evidence for major maize production in lowland areas, where erosion is less likely and agriculture was presumably more sustainable for the Maya people. The Maya civilization reached its peak between 250 and 900 A.D., and first emerged...

A typical landscaped yard consists of lawn area and ornamental plants. If watered properly, homeowners can see the beauty, pocket some green and save some water, according to a Texas A&M University turfgrass professor. Supplemental watering of urban lawns and landscaped areas is required to keep the plants healthy through the typical long, hot and dry summers and falls in Texas, according to Dr. Richard White, Texas AgriLife Research turfgrass management scientist in College Station....

Fertilizing one's lawn is considered a necessary practice, as is with most agricultural crops. But how many people know about fertilizing a commercial forest, and how that might affect the environment and their investment? Dr. Jason Vogel, assistant professor of forest ecosystem science within the Texas A&M University department of ecosystem science and management, is studying just how much difference fertilization can make to the productivity of the forest and carbon sequestration....

Phosphorus (P) is both an essential nutrient in agricultural fields and a contributor to poor water quality in surface waters. To encourage improved P management in fields, the P Index was proposed as a risk assessment tool in 1992. After 20 years of use, modifications, and growing pains, does the P Index accurately assess the risk of P loss? A special section being published next month in the Journal of Environmental Quality addresses that question. The collection of papers grew out of a...

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...
