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...
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...
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...
If the soil layer on top of the grass is not dense enough, grass shoots or weeds might pop through and disturb your garden. If you have a strong, healthy lawn, your grass roots can be up to 2 or 3 feet deep. Take the time to remove all grass and weeds in the area where you wa...
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 rhizodeposi

“bomb” radio carbon added to the atmosphere by thermonuclear weapons testing since the early 1960s. As soils are open systems, to which C newly fixed from the atmosphere is continuously added and from which C is continuously lost by decomposition, the ∆14C values of soil organic C change...
Nvidia is now worth more than the entire FTSE 100 as the US tech giant cashes in on the artificial intelligence (AI) boom. Shares in Nvidia have risen more than 13pc over the last five days after bosses this week revealed sales trebled ...
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...
