MU grad student simulates 100 years of farming to measure agriculture’s impact on land and water quality

Estimating the long-term impact of agriculture on land is tricky when you don’t have much information about what a field was like before it was farmed. Some fields in Missouri started producing crops more than a century ago—long before anyone kept detailed records about the physical and chemical properties of the soil in a field.
Researchers can’t go back in time to revisit old fields in their pristine state, but a University of Missouri graduate student did perhaps the next best thing, using a detailed computer model to simulate, year-by-year, the effects of 100 years of farming on claypan soils.
This can help determine the impact of certain conservation practices on farmland’s crop yields and soil and …

Natural And Organic Vegetable Gardening – 5 Essential Components To Accomplishment

The very first point most folks consider of when they hear the word, “organic” is no chemical substances. Whilst it is genuine that organic gardening excludes the use of most all chemicals, there is actually much a lot more to “organic” than just the absence of toxins. Correct organic gardening takes the whole eco-technique into account. The best way to construct this type of earth is with compost from untreated chemical totally free yard debris and kitchen scraps. Books like “Residence Composting Made Easy” and “Worms Eat My Garbage” are great resources for understanding distinct techniques to compost.
The 2nd most essential element is good planning. These will be harvested prior to the 1st envisioned frost …

Fuel treatments reduce wildfire severity, tree mortality in Washington forests

A study conducted by U.S. Forest Service and University of Washington (UW) scientists has found that fuel treatments—even of only a few acres—can reduce fire severity and protect older trees desirable for their timber, wildlife, and carbon-storage value. The finding is part of a three-year study of the 175,000-acre Tripod Fire and is published in the August issue of Canadian Journal of Forest Research.
“This study provides the most definitive evidence yet of the effectiveness of fuel treatments in dry forests of the Pacific Northwest,” said Susan Prichard, a UW research scientist and senior author of the study. “If dense forests are thinned and the surface fuels are removed, then ponderosa pine and Douglas-fir trees have …

Forest Fires Help Power the Nitrogen Cycle

When fire burns down a forest, nitrate levels go up, and the effects are persistent, according to recent research from University of Montana scientists. They found that charcoal deposited during fire events has the potential to stimulate the conversion of ammonia to nitrates, an important step in the nitrogen cycle.
Led by Patrick Ball, the research team found that a type of bacteria that transforms ammonia into nitrates was found in greater abundance in recently burned sites, despite the fact that the “recent” fire was twelve years prior to the sampling period. In addition to the bacteria, the burned sites had greater rates of nitrification, meaning that nitrogen was being processed more quickly through the ecosystem …

Greenhouse Gas Calculator Connects Farming Practices with Carbon Credits

Web-based tool helps farmers reduce greenhouse gas losses and gain economic advantage
Greenhouse gas markets, where invisible gases are traded, must seem like black boxes to most people. Farmers can make money on these markets, such as the Chicago Climate Exchange, by installing methane capture technologies in animal-based systems, no-till farming, establishing grasslands, and planting trees.
Farmers, students, extension educators, offset aggregators, and other stakeholders need to understand how to change farming practices to maximize their potential economic returns in these new markets.
To open the black box, researchers at the W.K. Kellogg Biological Station, including Claire P. McSwiney, Sven Bohm, Peter R. Grace, and G. Philip Robertson, developed the Farming Systems Greenhouse Gas Emissions Calculator, a simple …
