Global nitrogen availability consistent for past 500 years linked to carbon levels
2013-03-21 17:14:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A Kansas State University research team has found that despite humans increasing nitrogen production through industrialization, nitrogen availability in many ecosystems has remained steady for the past 500 years. Their work appears in the journal Nature. "People have been really interested in nitrogen in current times because it's a major pollutant," said Kendra McLauchlan, assistant professor of geography and director of the university's Paleoenvironmental Laboratory. "Humans are producing a...

Post-Drought Nitrogen Carryover Could Benefit Wheat Growers
2013-03-14 21:39:00| National Hog Farmer
Source: Purdue University Soil nitrogen left behind by Indiana's drought-stricken 2012 corn crop could mean that the state's wheat growers might be able to apply less fertilizer this spring, a group of Purdue Extension agronomists say. Corn plants stressed by extreme heat and too little water yielded less grain and left more nitrogen in soils than in normal years. Wheat has more potential to scavenge the nutrient than a subsequent corn crop. read more

Know Soil Nitrogen Levels Before Applying More Fertilizer
2013-02-25 23:32:00| Corn & Soybean Digest
Smart management can help growers get them bang for their buck on fertilizer. Source: Pioneer When traveling, knowing how much fuel is in your gas tank versus how much is needed to get to your destination is important. Similarly, knowing how much nitrogen you start with in the soil and how much is needed to get to maximum yields is critical. Realizing these numbers will help you be more efficient with your corn nitrogen (N) fertilizer. read more

Chinese Air Pollution Triggers Steep Rise in Nitrogen Deposition
2013-02-21 23:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: A spike in Chinese air pollution over the last three decades has caused a 60 percent increase in the levels of nitrogen pollutants that ultimately end up back on the nations land and in its water, a new study has found. In an analysis of 270 monitoring sites across the country, researchers found that the annual deposition of nitrogen, as measured in precipitation, had increased from 13.2 kilograms per hectare in 1980 to about 21.1 kilograms per hectare in 2010. Scientists say so-called nitrogen...
