15 صفحه اولDIVISION S-10-WETLAND SOILS Wetland Soils — Opportunities and Challenges
Wetlands are an important natural resource in the biosphere. Traditional terms used to describe wetlands are marshes, bogs, and swamps. Early European settlers considered these areas as wastelands and did not appreciate their values. For a number of years, many of these areas were drained and used as farmland, since these lands were found to be productive. Over a 200-yr time span (1780-1980), t...
متن کاملFumigating Soils and Plants
Fumigants differ from other types of insecticides in that the fumes must be confined so that the insect is exposed to a considerable concentration for some time. The length of exposure and the strength of the concentration are interrelated—the higher the concentration, the shorter the lethal exposure; the lower the concentration, the longer the exposure. Fumigants therefore are not well adapted...
متن کاملSoils, Peatlands, and Biomonitoring
Soils are three-dimensional (3D) natural bodies conSlStmg of unconsolidated mineral and organic materials that form a continuous blanket over most of the earth's land sUlface. At all scales of measurements, soils are exceedingly complex and variable in bio logical, chemical, physical, mineralogical, and electromagnetic properties. These properties influence the propaga tion velocity, attenuatio...
متن کاملSoils and Soil Sciences
Soil science is a relatively new discipline which has mainly developed since the 1880s. It uses terms, methods and processes borrowed from other basic disciplines like climatology, geology, chemistry, physics and biology, but with a direct application to soils. At present, it is difficult to speak about one single science but as soil sciences, as they cover several fields including: pedology (o...
