LEGO Bricks Turned Into Scientific Tool To Study Plant Growth
2014-06-27 03:19:07

Iowa State University Ludovico Cademartiri had what seemed like an impossibly demanding list of requirements for his lab equipment. The Iowa State University assistant professor of materials science and engineering wants to understand environmental effects on plant growth, specifically how variations in climate and soil characteristics affect root growth. That requires highly controlled environments that expose whole plants to environmental effects such as nutrients, water, oxygen...

MCLEAN, Va., June 24, 2014 /PRNewswire-USNewswire/ -- Current approaches may be underestimating the risks posed to children by toxic metals that they are exposed to while playing outdoors, according to Japanese researchers. The researchers used a new approach that they developed for their study of how much dirt and associated metals adheres to children's hands. They found that lead, chromium, zinc and other heavy metals adhere more to smaller soil particles than to the larger...

Water Provides Blueprints For Root Architecture
2014-06-10 03:00:34

Carnegie Institution Soil is a microscopic maze of nooks and crannies that hosts a wide array of life. Plants explore this environment by developing a complex branched network of roots that tap into scarce resources such as water and nutrients. How roots sense which regions of soil contain water and what effect this moisture has on the architecture of the root system has been unclear. New research from a team led by Carnegie's José Dinneny focuses on how physical properties of a root's...

Decomposing Logs Show Local Factors Play A Greater Role Than Climate
2014-06-03 15:34:25

By Kevin Dennehy, Yale University A new Yale-led study challenges the long-held assumption that climate is the primary driver of how quickly organic matter decomposes in different regions, a key piece of information used in formulating climate models. In a long-term analysis conducted across several sites in the eastern United States, a team of researchers found that local factors — from levels of fungal colonization to the specific physical locations of the wood — play a far...

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...
