Loam is soil composed mostly of sand and silt, and a smaller amount of clay (about 40%-40%-20% concentration, respectively). These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam.

Stormwater Irrigation

During recent decades there has been a growing national recognition that shrubs and trees in urban landscapes have both environmental and socioeconomic value. Research has shown that vegetation along streets and parking lots can lower urban temperatures and energy consumption (Halverson and Heisler 1981, Scott et al. 1999); filter, degrade,

In Hydroseeding, Weather Matters (A Lot)

Weather can be a hydroseeding contractor’s friend or foe. It can make a job much easier or much more difficult. It played a role in each of the following varied projects done by leading hydroseeding companies across the country.

Chemical Soil Stabilization – Part 1

Chemical Soil Stabilization – Part 1

Despite all the work done by earthmoving equipment, each year wind and rain move much more soil than man could ever hope to shovel. And because soil is a finite commodity, one has to hold on to as much of it as possible.

Plantings aid in this quest; the roots of

If It Quacks Like a Duck, It Could Someday Be a Wetland

On a sultry afternoon in mid-July, two bodies of water, entwined by nature but separated by man, became reacquainted for the first time in nearly 100 years. The estrangement had been quite stressful for both, but expedience had dictated that third-party interests—those of agriculture, commerce, and development—would take priority over

The Virginia Department of Transportation (VDOT) approved StormChambers for One Loudoun, a large mixed-use development in Ashburn, Loudoun County, VA. It was one of the first applications where VDOT runoff water—combined with private runoff water—went to this type of system, notes Steve Pandish, director of water resources for the engineering

Optimizing Irrigation

Optimizing Irrigation

Commercial growers, property managers, and landscapers can attest to how sophisticated and beneficial irrigation monitoring has become in terms of optimizing water consumption and plant growth, and maximizing operational profitability. Two examples from California—where much of the nation’s food supply is produced but where water availability remains a critical public

Soils may become degraded during the construction of buildings, roadside projects, or mining or landfill operations, or because of overgrazing or deforestation. They lose their topsoil, usually the top 2- to 8-inch layer of the soil, where the
