Installation of a water control box.

Box it up

Researchers say ‘control boxes’ could limit nitrate run-off 
from tile drains

Tile drainage is a boon in a wet spring but it can also increase nitrate run-off into nearby waterways and eventually lakes and even the ocean. The answer, when the problem was first discovered in the 1980s, was to develop “edge of field” practices, keeping saturated strips of natural landscape near streams to remove nitrates,

Still a lot to learn about hog nutrition

Ideas for small but significant changes may be difficult to incorporate into large-scale operations

As the hog industry becomes more integrated, small changes in nutrition can have significant financial impacts across large systems. That means that swine nutritionists and academics are challenged to think about what level of proof is needed for changes to be implemented in the barn. That is one of the conundrums facing swine nutrition, says

Editorial: An inconvenient truth

U.S. Wheat Associates and the National Association of Wheat Growers recently released the results of a study they commissioned on how much farm supports in four key markets are costing U.S. farmers. The premise behind the analysis, conducted by Iowa State University economists, is that countries such as Brazil, India, Turkey and China are depriving

When soybeans catch a chill, the farmer gets a cold.

Bringing soybeans in from the cold

A Brandon research scientist is studying the effects of cool temperatures during the Manitoba growing season

A Brandon research scientist is studying how cold temperatures during the growing season can put a chill on soybean production. Ramona Mohr, who works at the Agriculture and Agri-Food Canada’s Brandon Research Centre, says it starts with a “chilling effect” at planting. Mohr presented preliminary results from her studies at North Star Genetics’ annual soybean

Hundreds of protesters participated in the event, held ahead of the Nov. 15 G20 summit in Brisbane, which was being promoted as a message to Australian Prime Minister Tony Abbott’s government that, “You have your head in the sand on climate change.”

Study finds farmers and scientists divided over climate change

Focusing on the cause tends to polarize and politicize the discussion, which delays adaptation

Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows. Associate professor of natural resource social science, Linda Prokopy and fellow researchers surveyed 6,795 people in the agricultural sector in 2011-12 to determine their beliefs about climate change and whether variation

Optimizing the use of energy in pig feeds

With the cost of dietary energy more than doubling in the last eight years, it’s vitally important to optimize the efficiency with which it is utilized. Meeting the energy specifications of a typical grower diet now represents about 85 per cent of the cost of the diet and over 50 per cent of the total

Like most American belts, the Corn Belt has expanded too

North Dakota corn acreage has doubled since 2006 and quadrupled since 2001 Reuters / A combination of a long-term warming trend, improved varieties and soaring profits has sparked a “corn boom” in the Northern Plains that might one day turn North and South Dakota into the new Iowa, analysts say. “All you need to do
