The reluctance of bio-oceanographers to place iron limitation of phytoplankton growth on an equal footing with light or macronutrients can be attributed to several reasons. Thus, the issue of whether N or P is the primary limiting nutrient in oceans relative to lakes (where P has long been accepted as the limiting nutrient) was hotly debated for both coastal eutrophic waters as well as the open ocean. However, the concept was not transferred to iron by the mainstream community, possibly because many of the scientists involved were working in coastal areas where iron was not an issue. Indeed an early, albeit inadvertent, iron fertilization experiment was carried out by a titanium factory in the form of acid waste dumping in the North Sea where no noticeable effects on phytoplankton productivity were reported. The practice was stopped due to popular protest and the acid waste is now converted to FeSO4 and applied to lawns and sewage treatment plants. Cost, pollution and expertise cannot...

In other marginal areas, salt marsh vegetation can benefit from moderate goose grazing by arresting succession and preventing the establishment of taller species (van der Wal et al., 2000). High brent goose (Branta bernicla) populations can in this way increase the areal extent of grazing lawns (Person et al., 2003). There can also be a benefit from grazing by both mammals and geese. On the Dutch island of Schiermonnikoog, tall-growing shrub species such as sea purslane (Atriplex portulacoides) can eventually make the marsh unsuitable
Recycling is often the next most cost effective adaptation to reduced water supplies or increased demand for water. Used water can be purified and reused in industry, on farms and domestically. Gray water is untreated or semi treated wastewater that can be cheaply used for such things as irrigating golf courses, lawns, parks and gardens in urban and suburban areas. It is also effective in recharging groundwater storage. Recycling the same water during production is an example of a design change from improved technology that can save large amounts of water. While such changes may temporarily increase costs, they ultimately lead to increased savings as the price of steadily decreasing water supply rises. Through improved technologies, even now many cities reuse their own wastewater directly in what is called closed loop reclamation through the 3Rs of return, repurify and reuse. Water recycling also reduces water pollution.
Much of the desert Southwest region of the United States was settled in the past century following a century of historically high rainfall. Towns and cities grew, and the Bureau of Land Management diverted water from melting snows, rivers, and underground aquifers to meet the needs of growing cities. Some of the country's largest and newest cities, including Phoenix, Tucson, Denver, Las Vegas, Los Angeles, San Diego, and Albuquerque, have grown out of the desert using water from the Colorado River system. Even though the temperatures can be high, the air is good, and many people have chosen to move to these regions to escape crowded, polluted, or allergen-rich cities and air elsewhere. The surge in population has been met with increases in the water diverted to these cities, and fountains, swimming pools, resorts, golf courses, and green lawns have sprung up all over. In general the life can be comfortable.

At the other end of the world, on the rocky edges of the Antarctic Peninsula, a noticeable warming has occurred over recent decades. On the west side of the Peninsula, temperatures have gone up by 2.6 C since the 1940s. This warming has resulted in a veritable population explosion of the only two types of vascular plants known from Antarctica a grass (Deschampsia an l arc tic a) and a tiny member of the cabbage family (Colohanthus qui ensis). At sites where these two species have been monitored over more than 30 years, they have expanded from scattered plants and clumps to form the first lawns on Antarctica.
This Chapter provides methods for estimating carbon stock changes and greenhouse gas emissions and removals associated with changes in biomass, dead organic matter (DOM), and soil carbon on lands classified as settlements. Settlements are defined in Chapter 3 as including all developed land -- i.e., residential, transportation, commercial, and production (commercial, manufacturing) infrastructure of any size, unless it is already included under other land-use categories. The land-use category Settlements includes soils, herbaceous perennial vegetation such as turf grass and garden plants, trees in rural settlements, homestead gardens and urban areas. Examples of settlements include land along streets, in residential (rural and urban) and commercial lawns, in public and private gardens, in golf courses and athletic fields, and in parks, provided such land is functionally or administratively associated with particular cities, villages or other settlement types and is not accounted for...
The variation is less per unit land area for ten cities in the United States, measurements of C stored in woody biomass ranged from 150 to 940 kg C ha-1 yr-1 (Nowak and Crane, 2002) and for three Korean cities annual C stored in woody biomass varied from 530 to 800 kg C ha-1 yr-1 (Jo, 2002). Trees in urban lawns in Colorado (USA) stored 1,590 kg C ha-1 yr-1 (Kaye et al., 2005). There is still less variation in estimates of annual C storage per unit of tree crown cover. Nowak and Crane (2002) found that annual sequestration rates ranged from 0.12 to 0.26 kg C m-2 crown cover yr-1, while Brack (2002) used a model to estimate that annual sequestration in Canberra between 2008 and 2012 would be 0.27 kg C m-2 yr-1.
No studies have yet been published on the accumulation rate of dead wood in settlements, though some studies have described the production of leaf litter in settlements (cf. Jo and McPherson, 1995). In the only measured data on this component of carbon flux, Kaye et al. (2005) found that leaf and shrub litter in residential lawns in Colorado (USA) totalled 49 g C m-2 yr-1, or roughly 13 of total above-ground productivity (383 g C m-2 yr-1). Since the rate of soil respiration in settlements is typically quite high compared to native landscapes (Koerner and Klopatek, 2002 Kaye et al., 2005), it is likely that fine litterfall decays quickly. The conservative approach, therefore, is to set the accumulation rate of the litter component of DOM to zero.
Recordkeeping, and reporting provisions is required provisions is required by July 15, 1993. For the most part, the rule is self implementing, which means that citizen suits or EPA can enforce the regulation even before permits are issued. The standards will be incorporated into National Pollution Discharge Elimination System (NPDES) permits issued by EPA or permits issued by states with approved biosolids management programs. EPA will work closely with the states to encourage their adoption of approved biosolids management programs that can carry out delegated programs. Land Applied Biosolids must Meet Quality Requirements. Land application includes all forms of applying bulk or bagged biosolids to land for beneficial uses at argonomic rates (rates designed to provide the amount of nitrogen needed by the vegetation while minimizing the amount that passes below the root zone). These include application to agricultural land pasture and range land nonagricultural land such as forests...
Earth.* It was oldest of the few known Martian meteorites. Yet it was an unremarkable kind of thing, a medium-sized, green-black rock. If it landed on your lawn, you might not notice. Other meteorites, possibly even older meteorites, have probably landed in gardens, then been cursed and tossed into the weeds.
The second parameter in determining biosolids quality is the presence or absence of pathogens such as Salmonella bacteria, enteric viruses, and viable helminth ova. Biosolids are classified as class A or B based on the level of pathogen present. Biosolids meet class A designation if pathogens are practically below detectable levels. All biosolids that are sold or given away in a bag or other container for application to land, lawns, or home gardens must meet class A status. Part 503 lists six alternatives for treating sludge to meet class A requirements. These alternatives are summarized in Table 1.6. One of the alternatives is to treat sludge in one of the processes to further reduce pathogens (PFRP), which are described in Table 1.8.
Charles Parish had suffered significant damage from the storm, but was in an excellent position to mount a rapid recovery. The early decisions to remove debris from roads and establish potable water and a working sewerage system proved critical. These allowed residents to return earlier, minimizing ongoing damage to property (roof leaks were repaired or covered, etc), and further hastening the removal of debris (everyone cleared their own lawns). Some businesses were able to reopen on generator power, with their regular employees available for work and their regular customers lining up at the doors. Shortly thereafter, convoys of power trucks arrived to repair the power lines. As Jefferson Parish and Orleans Parish were still inaccessible, they repaired the damaged power lines in St. Charles Parish instead. My own home in St. Charles Parish had electrical power restored exactly one week after the storm (by comparision, I had no power for 3 weeks after the much weaker Hurricane...
Since freshwater is essential for life, it may be considered an economic resource to manage effectively. Water is needed for drinking, irrigation, household, recreational, and industrial applications. In the United States agriculture uses about 43 percent of all water resources, and industry uses another 38 percent. On a global scale irrigation for agriculture accounts for an even higher percentage of water use, an estimated 69 percent of total water consumption, whereas industry uses only about 15 percent of water on a global scale. Most of the rest of the water is used by households, for drinking, washing, watering lawns, pools, and other benefits of affluent society. Americans use an average of 1,585 gallons (6,000 L) of water a day, compared with a bare one-half gallon ( 2 L) a day needed for survival. Americans use about two to four times as much water as inhabitants of Western Europe, and much more than people in drought- and poverty-stricken countries in Africa and the rest of...
Millions of pounds (1 lb 0.454 k) of pesticides are used on croplands, forests, lawns, and gardens in the United States each year. A large quantity of hazardous pesticides is also released by the pesticide industry to the environment. These hazardous pesticides drain off into surface waters or seep into underground water supplies. Many pesticides pose health problems if they get into drinking water and the water is not properly treated. The maximum limits for pesticides in drinking water are (a) endrin, 0.0002 mg L (b) lindane, 0.004 mg L (c) methoxychlor, 0.1 mg L (d) toxaphene, 0.005 mg L (e) 2, 4-D,
In this same context it is relevant to note that when carbon dioxide enrichment was applied in the atmosphere as in the Free-air Carbon Dioxide Enrichment (FACE) experiments on ombrotrophic peat bog lawns in Finland, Sweden, the Netherlands and Switzerland there were no significant effects on sphagna or vascular plant biomass at any of the sites even after a three-year treatment with an increased atmospheric carbon dioxide concentration at 560 ppm (Hoosbeek et al., 2001). This suggests that, just as with other nutrient-poor ecosystems, increased atmospheric carbon dioxide concentrations will have a limited effect on bog ecosystems. However, given the ability of Sphagnum magellanicum to utilize the carbon dioxide in the soil water, it is hardly surprising that carbon dioxide enrichment of the atmosphere has little effect on wetland mosses.
