Nitrogen management in a wet spring

2016-05-13 20:03:00| Corn & Soybean Digest

Source: University of Nebraska-Lincoln Planting may be in the front of everyones mind, but farmers should not lose sight of nitrogen management, particularly after the recent rains. With the extra moisture, water movement through the soil creates reason for nitrogen leaching concerns. read more

Dry Media Dust Collector or Wet Scrubber?

2016-04-28 14:35:00| Chemical Processing

Wet scrubbers and dry media dust collectors are two very different technologies used to capture dusts generated during production processes. Both types have inherent advantages and disadvantages. Which is best for your application? The choice is not always clear-cut, but this white paper will help with the decision process by providing a comparison between wet and dry dust collectors. It will outline general parameters for equipment selection with respect to dust properties including combustibility, explosibility, particle size, moisture and adhesiveness. It will also discuss how to apply NFPA 484: Standard for Combustible Metals, the standard that best addresses wet collection. Though NFPA 484 is specific to metals, some of its content can and should apply to nonmetal combustible dusts. Download the white paper now.

Climate models overestimate increase in wet and dry extremes

2016-04-08 10:45:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Home: The 20th century was neither much drier nor wetter for half the globe than many of its predecessors, European scientists say. On the contrary, they say several centuries in the last 1,200 years experienced much more variable rain and drought than the 1900s. Their findings, which are published with several caveats and which have not so far been replicated, differ markedly from the conclusions published by the Intergovernmental Panel on Climate Change (IPCC). In what they say is the first...

Climate data since Vikings cast doubt on more wet, dry extremes

2016-04-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: OSLO Climate records back to Viking times show the 20th century was unexceptional for rainfall and droughts despite assumptions that global warming would trigger more wet and dry extremes, a study showed on Wednesday. Stretching back 1,200 years, written accounts of climate and data from tree rings, ice cores and marine sediments in the northern hemisphere indicated that variations in the extremes in the 20th century were less than in some past centuries. "Several other centuries show stronger...
