Tag: about soil

Soil is the mixture of minerals, organic matter, gases, liquids, and the countless organisms that together support life on Earth. Soil is a natural body known as the pedosphere and which performs four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of Earth’s atmosphere; it is a habitat for organisms; all of which, in turn, modify the soil.

Keeping Them Alive

No contractor wants to make headlines because of a trench collapse. When a collapse results in the death of a laborer? That’s tragic, and the resulting fines and lawsuits could be enough to put even large contractors out of business.

But it doesn’t take a fatality for contractors to suffer a serious hit on

OSHA and the Competent Person

OSHA and the Competent Person

OSHA officials have long recognized the potential danger that employees face when doing trenching or excavation work. That’s why OSHA requires that a competent person be onsite when construction crews are doing this kind of work.

According to the OSHA Construction Standard, a work site’s competent person must be capable of identifying existing

Barriers to Implementing LID

Barriers to Implementing LID

Low-impact-development stormwater management approaches are gaining in popularity and are being increasingly written into permitting requirements. While a number of barriers to implementation continue to come into play, advocates are finding more solutions to those obstacles, according to experts across the country. “We cannot just trumpet the wonderful qualities of

Going Native

Going Native

Consider this: Using native species-grasses and wildflowers-as landfill cover is more cost-effective than using conventional vegetation strategies and provides benefits that go a long way in gaining public acceptance. Going native is the right decision when it comes to landfill cover for a number of reasons. Reason 1-Natives work

Checking It Twice

Checking It Twice

In January 1995, pile-driving crews knocked out all electrical power at Newark International Airport’s three passenger terminals and forced the airport to close for a day. All international and many domestic flights were canceled or diverted from Newark, which handles 1,200 flights a day. Electricity to the air traffic control

What You Need for Seed

What You Need for Seed

It probably goes without saying: If the site was perfect, it likely wouldn’t need erosion control. Good soil, good drainage, a gentle slope or none, plenty of vegetation-in real life, that’s the “after” photo. No wonder your work is so challenging! It’s often difficult enough to get control measures in

Getting Down to Earth

What would happen if we didn’t do the right compaction? If we were building a house, the walls would crack and the whole structure could fall down. If we were making a sidewalk or driveway, the surface would crack quickly to become a hazard for users, pedestrian and driving. If

Bioengineering for Soil Stabilization

From the vegetated reinforced soil slopes on the banks of Johnson Creek in Portland, OR, to an erosion control demonstration project on the banks of wind-whipped Lake Winneconne in Wisconsin, geosynthetic materials are going where they’ve never gone before in an effort to accomplish a much wider range of functions.
