Ground cover

A new source of safrole that Strike has just stumbled upon is in Strike s back yard. Momma comes home from the local nursery with two plants that have these enormous leaves. They are succulents and grow like crazy. Strike What ya got there Momma Momma Don t think I haven t noticed those filthy drug books you write, you sick little monkey Strike Aw c mon. Mom. Let s not get into this again. Strike doesn t... Momma Well I needed some new ground cover plants, and...sigh...I know you re into this twisted licorice thing...so I bought these weeds that are called Licorice Plants. ...

Another product EPDM is a rubber-like material. It comes in 60-mil thickness in 100 ft by 61-1/2 in. rolls. EPDM also comes in 45-mil thickness in 25 ft by 60 ft rolls. This product has gained popularity as a ground cover in crawlspaces because of its durability qualities. 

By predicting PbB levels, a determination can be made about what health impacts may be occurring at a given site. This will assist health assessment personnel in deciding whether further action is needed. A site-specific evaluation must be made before reaching any conclusions (e.g., pica children, ground cover over contaminated soil, nutritional status and age of the population, etc.). Issues relevant to children are explicitly discussed in Sections 2.6, Children s Susceptibility, and 5.6, Exposures of Children.

A new concrete floor incorporating barriers to radon transport from the subsoil appeared to be only partially successful in reducing radon decay-product concentrations. It was shown that the Venturi effect of the wind across two chimney stacks caused pressure-driven flow of radon from the ground. Covering the fireplaces to eliminate this effect resulted in concentrations below the reference level. 

Ground covers in banana plantations are favorable for retention of moisture. A desirable ground cover consists of broad-leafed plants, but grasses predominate in many areas. Chemical control of grasses is not favored because banana plants are sensitive to chemicals, so the areas are hand chopped at frequent intervals. The banana plant is a rapid growing, highly succulent, perennial herb that is easily damaged with as little as 7.5 pounds of CMU [3-(p-chlorophenyl)-l,l-dimethylurea] per acre applied in a semicircular strip within 2 feet of the plant. This plant is sensitive to 2,4-D and can be injured by low concentrations. 

The tsetse flies are viviparous. The egg is retained and hatched in the body of the female fly, where it is nourished until full grown, then it is deposited on loose or sandy soil in a shaded place. The larva pupates within a few hours and after several weeks an adult fly emerges. The gestation period in the fly is about 10 days, and the flies may reproduce over a period of several months. Most of the species are limited to fly belts within their respective ranges. Shade and abundant ground cover characterize typical fly belts. 

Table 1 summarises the features of equipment design which influence the risks of odour problems arising from surface spreading. There are numerous combinations of these features to be found in slurry tankers however, tanker design is often directed more to productivity in terms of speed of operating and area of ground covered rather than to minimising odour and aerosol production. 

During the next phase of construction, the basement and sub-basement of the house are dug. This excavation draws tens of thousands of tons of B (and sometimes C) Horizon soils to the surface. With little or no resale value, these soils are simply spread around the surface of the site to serve as the basis for landscaping after construction is complete. Starved of organic material and loaded with minerals (not to mention plaster, cement, lumber, and other debris), these soils are a prohibitively poor base for planting. It is little wonder mulch is an increasingly popular ground cover in the suburbs. 

Even so, most of the practical options available to individuals are low-cost, simple, and based on widely available information and resources. At the individual level, alternatives are most commonly implemented by growing ground covers other than turfgrass-either by simply aUovmig secondary succession to establish whatever diverse herbaceous, shmb, and tree species grow on a neglected plot, or instead by actively planting new communities, especially of native species. ... 

Virginia Scott Jenkins now-classic 1994 volume, The Lawn An American Obsession, carefully and exhaustively traces the arrival of the turfgrass lavm to America and its expansion into a ubiquitous ground cover, with serious attention to the environmental problems that such a transformation entailed. This work is especially notable for the way it emphasizes the remarkably recent history of a landscape that seems so quintessentially normal and timeless to many of us. ... 

An effective and environmentally friendly acoustic barrier consists of a framework of woven, freshly cut willow, filled with soil, into which the willow stems root. Variations include a soil-filled framework of dried willow, in which ground-cover plants are established. Dense, compressed reed walls designed to reduce noise are also available.
