North American Manure Expo comes to Canada...
For the first time ever, the North American Manure Expo is being hosted within a Canadian province. The annual show is being held August 20 and 21, 2013, at the University of Guelph’s Arkell Research Station, located near Guelph, Ontario. So, what's a Manure Expo and why should you attend? This video will provide all the dirt.

With the world's population increasing exponentially and farmland staying the same, BASF took to the streets to ask consumers if this trend is sustainable.
July 28, 2015 - U.S. Department of Agriculture (USDA) scientists have found that a natural seed coating can protect alfalfa against some soilborne diseases. Alfalfa is a $10 billion-a-year crop in the U.S., but producing it can be a challenge. Farmers in the Midwest often plant it early in the spring when the soil is cold and damp. That makes the seeds vulnerable to a number of soilborne diseases. To minimize the damage, most alfalfa seeds are coated with a fungicidal treatment. But the treatment, mefenoxam, is ineffective against the pathogen causing Aphanomyces root rot (ARR), which is common to Midwestern soils.Demand for organic alfalfa for organic dairy operations also is increasing, and alfalfa treated with a fungicide can't be labeled as organic. Many organic dairy farmers would like to expand but may face a roadblock due to a lack of available organic feed, according to Deborah Samac, a plant pathologist in the Agricultural Research Service's (ARS) Plant Science Research Unit in St. Paul, MN. Samac wanted to see if coating alfalfa seeds with a naturally occurring mineral would protect them from soil diseases, including ARR. The mineral, zeolite, comes from degraded volcanic rock, has antifungal activity, and qualifies as an organic soil treatment. Samac also wanted to assess zeolite's effects on the health of plant roots and beneficial soil microbes. She and her colleagues grew plants with three different seed treatments and inoculated them with the types of pathogens that attack alfalfa roots. The seed treatments included a control with no fungicide, mefenoxam-treated seeds, and commercially available zeolite-coated seeds designed for organic alfalfa production. The plants were removed after 21 days and rated for disease symptoms on a 1-to-5 scale. They also repeated the process in soils collected from 12 Minnesota alfalfa fields to assess the treatment's effectiveness in soil naturally infested with pathogens. The results showed that the mineral coating was as effective as mefenoxam in protecting seeds from most soil pathogens, but unlike mefenoxam, zeolite protected the seeds from ARR. It also did not inhibit production of healthy roots or beneficial microbes in the soil. The coated seeds need to be evaluated further, but the findings show they could prove useful in both conventional and organic alfalfa operations, Samac says. The results were published May 29, 2015, in the journal Plant Disease.
July 21, 2015 - The new SW750 air cart from Horsch LLC offers unmatched efficiency and versatility with its three-bin design and 750-bushel capacity. The SW750 comes standard with dual 710/70R38 tires, but can also be equipped with 36-inch tracks for higher flotation, decreased compaction and a lower horsepower requirement when compared with competing air carts. Customers also have the choice of a standard 10-inch auger or an optional 16-inch conveyor for faster, gentler loading of commodities. Other options on the SW750 include a 60-bushel small grain/inoculant tank, as well as scales with live weight readout for the three individual tanks. The air cart is compatible with ISOBUS or Raven Electronics. It does not require any additional monitors or cabling in the tractor, helping to simplify setup and operation.
