A series of studies at Purdue University has shown that spray water pH and hardness can reduce the effectiveness of herbicides, making it vitally important for crop producers to test water sources. Hard water or water with pH values as low as 4 or as high as 9 have been shown to lower the efficacy of herbicides, including glyphosate, nicosulfuron and saflufenacil, said Bill Johnson, Purdue Extension weed scientist and professor of botany and plant pathology. An ideal pH value would be 6-7.

Idaho alfalfa hay acreage was 1 million acres in 2011 (NASS, 2012), which was down 130,000 acres from 2010. Peak alfalfa hay acreage was 1.2 million acres in 2003.

Production was 4.3 million tons and if we assume an average value of $225/ton, then alfalfa hay was worth $967 million in Idaho for 2011.

Less acres and a dip in yield produced reduced hay stocks compared to past years and some livestock operations may not have adequate supplies to last them until first cutting.

The U.S. Department of Agriculture (USDA) today released the new version of its Plant Hardiness Zone Map (PHZM), updating a useful tool for gardeners and researchers for the first time since 1990 with greater accuracy and detail. The new map – jointly developed by USDA's Agricultural Research Service (ARS) and Oregon State University's (OSU) PRISM Climate Group – is available online at www.planthardiness.ars.usda.gov. ARS is the chief intramural scientific research agency of USDA. For the first time, the new map offers a Geographic Information System (GIS)-based interactive format and is specifically designed to be Internet-friendly. The map website also incorporates a "find your zone by ZIP code" function. Static images of national, regional and state maps also have been included to ensure the map is readily accessible to those who lack broadband Internet access.

Cattle that graze on rangelands in the western United States may soon have a new forage option, thanks to work by a U.S. Department of Agriculture (USDA) scientist. Research by geneticist Blair Waldron with USDA's Agricultural Research Service (ARS) in Logan, Utah, suggests that forage kochia (Kochia prostrata) can provide more nutritious winter forage than traditional rangeland vegetation. ARS is USDA's chief intramural scientific research agency, and this work supports the USDA priorities of responding to climate change and promoting international food security. Waldron and his cooperators in Utah partnered to learn more about forage kochia, a shrubby Asian native plant that sometimes survives wildfires and other environmental challenges more successfully than North American native plants. Waldron works at the ARS Forage and Range Research Laboratory in Logan.

In many high-yielding areas of the Corn Belt, residue buildup has become a challenge. DuPont businesses Pioneer Hi-Bred and DuPont Industrial Biosciences are collaborating with Iowa State University, performing studies on residue to establish best practices in harvesting, storage and transportation, as well as to assure the agronomic and environmental integrity of cornfields. "We know the near-term benefits of residue removal," says Andy Heggenstaller, Pioneer agronomy research manager from Iowa. "We're now trying to learn how to take advantage of these benefits with an eye toward achieving similar long-term agronomic advantages."

Two Center Pivot Irrigation Management Short Courses have been planned to enhancing the value of water through advanced irrigation management practices. Short courses have been planned for February 6, 2012, at the Monsanto Water Utilization Learning Center near Gothenburg and for February 8, 2012, at the Cornerstone Ag & Event Center on the York County Fairgrounds in York.  

Dave Young, NW Regional Manager for Cornell Pump, last week was named the Agriculture Chair for the 2013 Idaho Irrigation Equipment Show and Conference. Young will secure speakers, workshops and activities to support Idaho’s largest agriculture irrigation conference, hosted by the Idaho Irrigation Equipment Association (IIEA).

The American Society of Agricultural and Biological Engineers (ASABE) has revised its standard for agricultural baling twine. The revised ASABE standard ANSI/ASAE S315.4, Agricultural Baling Twine for Automatic Balers, reflects current increased twine strength for small and large square bales and also includes twine for round bales. The data for the newly incorporated values were provided and evaluated by a diverse committee of industry experts.

New York Farm Show is proud to announce that the Oxbo 4334 Self Propelled Merger will be on display, Feburary 23-25 at the New York State Fair Grounds. “We are proud to be a part of this introduction of new technology for the forage industry.  Oxbo has the leading edge in merging hay,” said Scott Grigor, New York Farm Show Manager.
