Michael Crumbliss for redOrbit.com China has the worst pollution problems in the world. And it is getting worse as the utterly unchecked rush to industrialization continues. Much of this is pollution is linked to coal mining and power generation, but the sources of toxins are myriad. While air and water pollution are highly visible and overwhelming on an everyday basis, the worst long-term toxic buildup may be lurking quietly underfoot in the soil. Nowhere is the global push to restore...

Insects can use plants as ℠green phones´ for communication with other bugs. A new study now shows that through those same plants insects are also able to leave ℠voicemail´ messages in the soil. Herbivorous insects store their voicemails via their effects on soil fungi. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Wageningen University (WUR) discovered this unique messaging service in the ragwort plant. The influential journal Ecology Letters will...

Microbes Capable of Surviving Harsh, Mars-Like Conditions Discovered
2012-06-09 05:58:05

Soil samples obtained from South American volcanoes have revealed a smattering of different microbe types that have somehow managed to survive in extreme conditions, the University of Colorado-Boulder (CU-Boulder) announced in a June 8 press release. According to the university, the scientists behind the research discovered bacteria, fungi, and a different type of simple organism known as archaea living in conditions similar to Mars -- a landscape which they dub "some of the most...

The June GSA TODAY science article is now online and open access at http://www.geosociety.org/gsatoday/. In this issue, Gregory Retallack and Joshua Roering of the University of Oregon enter the long-standing debate as to whether rock platforms along coasts and rivers are the product of physical erosion or chemical weathering above the water table. Although the notion of wave-cut or stream-cut platforms is firmly entrenched in the literature, Retallack and Roering present the case that a...

SMOS Images Europe’s Dry Soils From Space
2012-05-31 03:05:53

The trend of below-average rainfall across Europe has continued into the first months of 2012. ESA´s SMOS water mission has revealed the negative consequences of this recent bout of ℠good´ weather. Western Europe is experiencing a severe lack of water because of this trend. Concern about the deficit of water is rising across European countries and their respective water agencies, in particular in Spain, France, Germany and the UK. The absence of sufficient water...

Underground soil cracks persist Deep cracks in soil can remain open underground even after they have visibly sealed on the surface, a new study has found. The results could have important implications for agricultural management around the timing and intensity of water and pesticide applications. "These soils are very fertile and provide the most productive agricultural land in Australia," said lead author Dr Anna-Katrin Greve, a postdoctoral fellow with UNSW's Connected Waters...

It was all too evident during the Dust Bowl what a disastrous impact wind can have on dry, unprotected topsoil. Now a new study has uncovered a less obvious, but still troubling, effect of wind: Not only can it carry away soil particles, but also the beneficial microbes that help build soil, detoxify contaminants, and recycle nutrients. Using a powerful DNA sequencing technique, called pyrosequencing, a team led by USDA-ARS scientists Terrence Gardner and Veronica...

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...
