Soils were sectioned and weighed for bulk density, then ground finely for uniformity and acidified to eliminate inorganic carbon. Percent carbon in the soil was then measured in a Flash 2000 CN Analyzer. We hypothesized that soil carbon stocks would be much higher in forests than in lawns. We...
Energy use is a factor weighed on a case-by-case basis. Money Recycling has a variety of economic impacts. For the companies that buy used goods, recycle them and resell new products, recycling is the source of all their income. For cities in densely populated areas that have to pay by...
The soil carbon (C) saturation concept suggests an upper limit to the storage of soil organic carbon (SOC). It is set by the mechanisms that protect soil organic matter from mineralization. Biochar has the capacity to protect new C, including rhizodeposits and microbial necromass. However, the ...
Understanding the mechanical properties of continental submarine slopes is critical for the assessment of geo-marine slope stability hazards. This paper pr
Bacteria break down the trash in the absence of oxygen (anaerobic) because the landfill is airtight. A byproduct of this anaerobic breakdown is landfill gas, which contains approximately 50 percent methane and 50 percent carbon dioxide with small amounts of nitrogen and oxygen. Methane is a seri...
Chalky: lumpy, large-grained soil, often with chunks of stone Peat: spongy soil found in wetlands If your soil is heavy and clay-like, you’ll probably want to invest in raised garden beds. It will be difficult for many plant roots to grow deep in dense clay soil. How to test soil...
Here’s everything you need to know about what a mutual fund is, how it works, and why they could be your most valuable tool for long-term investing.
Methane is a serious issue for landfills because it's a potent greenhouse gas, some 28 to 36 times more effective than carbon dioxide at trapping heat in the atmosphere. And landfill gas emissions are the third-largest source of methane emissions in the U.S., accounting for about 15 percent...
Which statement is true regarding pH in the ocean? a) The pH of deep water is lower because carbon dioxide is nearly absent there. b) The pH of deep water is higher because carbon dioxide is nearly absent there. c) The pH near the surface is higher be What is the largest fish...
The Woyie River rough diamond weighed 770 carats and was dubbed one of the largest alluvial diamonds ever to be found. And the Sergio diamond (3167 carats), weighing slightly more than the Cullinan, is a carbonado diamond, a rare black diamond. And more recently we wrote about the Lulo ...
