Celeriac is a celery variety refined over time to produce an increasingly large, solid, globular root just below the soil surface.
And what prevents soil and surface water contamination from countless units that ultimately wind up in landfills?
FORBES: How Many Politicians Are Needed To Screw Up A Light Bulb?
The remaining soil contamination is located several feet below uncontaminated surface soil.
Sub-surface soil samples will be analysed by an onboard laboratory.
In Washtenaw County and Ann Arbor, Michigan a 1, 4-Dioxane, in groundwater and surface soil contamination from Gelman Science, persists after nearly 20 years of cleanup activities and has now spread in groundwater to an area over three miles long and a mile wide.
Along with some pieces of uniform, a bottle, some coins and a pipe were found with the body, just below the surface of the soil.
Phase II, planned for 2011, will identify both aquifers down to 3, 000 meters below the surface, study soil composition and aquifer replenishment, and prioritize areas for agricultural development.
Because it doesn't stir up the soil, it lets the land keep its stored carbon and even adds some, because those corn stalks on the surface gradually become part of the soil.
In the vacuum, the sharp edges of the lunar soil cling together, leaving a smooth surface much as moist sand does on a beach.
Other culprits include the application of fertilizer in the fall, when the ground is bare, and the spreading of manure on the surface, instead of into the soil.
The water footprint includes both the water withdrawn from surface and groundwater and the use of soil water (in agricultural production).
It comes from a garden wholesaler, which provides the high quality soil, taken deep beneath the earth's surface -- 10 meters down, in fact.
Some scientists still defend those results: the soil may have had microbes living on ice beneath the surface, they say.
Its rover, Sojourner, journeyed onto the surface of Mars and performed scientific analyses of soil and at least one rock.
Deep chewing of plant roots, paired with the repeated soil chipping of hooves, caused dormant seeds to germinate and water to penetrate below the surface.
FORBES: Impact Investing in Sustainable Agriculture for a New Economy
In a number of areas the ground remains frozen beneath the surface, which means excess water will run into rivers instead of being absorbed by the soil.
"When you replace soil and grass with concrete and asphalt, you alter the balance of energy that occurs at the earth's surface, " says Dr. Robert Bornstein, a professor of meteorology at San Jose State University in California.
