Not exact matches

As microorganisms in the soil break down the organic material into an inorganic soluble form, a slow release of nutrients is provided over a longer period of time.

Any material (such as straw, plastic, or newspaper) applied over the soil surface to retard weed growth, conserve moisture, and maintain a uniform temperature.

The four requirements of such a designation are terroir, the region and soil contributing to the product; matiere premiere, the raw materials from which it's made; savoir - faire, the techniques of making the product; and tradition, or the knowledge of its manufacture built up over generations.

A team led by scientists at Lawrence Berkeley National Laboratory found that the type of plant inputs (that is, root or needle litter) affected total carbon and nitrogen retention over 10 years, but that soil horizon (essentially, the layer of soil, such as the topsoil organic or deeper mineral layers) affected how the litter - derived soil organic material is stabilized in the long term.

The team suspects that differences in decomposing plant material might have led to changes over time in the community of microbes that process nitrogen in the soil and make it available to plants.

Among the candidate materials is pedogenic carbonate, carbonate material that forms in soils over time.

The instrument measured roughly the same tiny concentration of water (about 2 percent) in the surface soils as it did in the freshly uncovered soil, and the newly excavated area did not dry out over time — as would be expected if moist subsurface material were uncovered.

This material — vaporized and molten rock — shoots over the surface, disturbing the upper layer of lunar soil and changing its brightness.

Over the last few decades, we've learned a lot more about how humic materials found in the earth's soil, including fulvic acid, can offer a host of benefits in the human body.

Branches from a thorny plant, like the rose of Sharon tree; wooden or plastic lattice fencing material; or chicken wire can be placed over the soil.

and give the following statistics for the contribution of each tree to the environment over a period of a twenty years: 10 000 kg of organic material which will fertilize the earth and prevent soil erosion; 400 000 litres of water, 28 000 m3 of oxygen which is enough to allow a person to breathe for 80 years; 25.000 m3 of CO2 helping to clean the air and slowing down the heating up of the earth.

Over the past week, at least four high - profile papers largely funded by the U.S. government have contributed new evidence, observations, and insight into the role of soil and forests in the global carbon cycle — the flow of material in and out of land, air, life, and sea that's currently broken and getting worse.

Hunched over the soil, Malagasy villagers work feverishly — deft fingers planting stalks of mangrove to replace the swathes destroyed for firewood and building material.

Tabulate the CO2 exhalation rates over the last 15,000 years from (i) terrestrial and submarine volcanism (including maars, gas vents, geysers and springs) and calc - silicate mineral formation, and (ii) CH4 oxidation to CO2 derived from CH4 exhalation by terrestrial and submarine volcanism, natural hydrocarbon leakage from sediments and sedimentary rocks, methane hydrates, soils, microbiological decay of plant material, arthropods, ruminants and terrestrial methanogenic bacteria to a depth of 4 km.
