Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license. Creative Commons licenses do not replace copyright, but are based upon it. They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an "all rights reserved" copyright management, with a "some rights reserved" management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner. The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees. Wikipedia uses one of these licenses.
A Gley (Russian: gley is dialectical word глей, literally "clay") is a wetland soil (hydric soil) that, unless drained, is saturated with groundwater for long enough periods to develop a characteristic gleyic colour pattern. This pattern is essentially made up of reddish, brownish or yellowish colours at surfaces of soil particles (peds) and/or in the upper soil horizons mixed with greyish/blueish colours inside the peds and/or deeper in the soil. Gleysols are also known as Gleyzems and meadow soils (Russia), Aqu-suborders of Entisols, Inceptisols and Mollisols (USDA soil taxonomy), or as groundwater soils and hydro-morphic soils.
Gleysols occur on wide range of unconsolidated materials, mainly fluvial, marine and lacustrine sediments of Pleistocene or Holocene age, with basic to acidic mineralogy. They are found in depression areas and low landscape positions with shallow groundwater.
Wetness is the main limitation of virgin Gleysols; these are covered with natural swamp vegetation and lie idle or are used for extensive grazing. Artificially drained Gleysols are used for arable cropping, dairy farming and horticulture. Gleysols in the tropics and subtropics are widely planted to rice.

Gleysols are soils that have undergone prolonged periods of intermittent or continuous saturation with water causing reducing conditions during their genesis.

Face it: We live in a society of germaphobes who have been brought up to believe that all bugs are bad bugs. But the fact is, most bugs, or shall we say microbes--which includes bacteria and fungi-- are actually good. And what’s more, microbes produce compounds which they use to defend themselves against their fellow microbes. These are naturally produced antibiotics. In fact the first antibiotics were extracted from soil microbes. These became the wonder drugs of the mid- 20th century, all but eliminating diseases like Tuberculosis. Recently, a team of scientists made a new discovery about microbes and antibiotics and the result has great promise in overcoming antibiotic resistance. Watch the 3 minute video to learn how our living soil stores the possibility of life-saving antibiot...
Twitter @juangangel Se denomina suelo a la parte superficial de la corteza terrestre, biológicamente activa, que proviene de la desintegración o alteración física y química de las rocas y de los residuos de las actividades de seres vivos que se asientan sobre ella. Los suelos son sistemas complejos donde ocurren una vasta gama de procesos físicos y biológicos que se ven reflejados en la gran variedad de suelos existentes en la tierra. Son muchos los procesos que pueden contribuir a crear un suelo particular, algunos de estos son: la deposición eólica, sedimentación en cursos de agua, meteorización, y deposición de material orgánico. De un modo simplificado puede decirse que las etapas implicadas en la formación del suelo son las siguientes: Disgregación mecánica de las rocas. Meteorización...
