Golden Valley, Minn. - August 13, 2007 - For 2008, NK is expanding its already diverse portfolio to include 23 new soybeans, all selected from extensive research at more than 800,000 soybean plots at eight Syngenta research centers throughout the United States.

"This powerful soybean lineup provides growers with a broad range of options for the toughest disease, pest and weed issues that maximize yield performance in your fields," says Jamie Leifker, NK marketing manager with Syngenta Seeds.

The new additions include six salt excluder soybeans, which limit distribution of chloride to vital plant parts, improving performance in salty fields. Plus, six of the new soybeans have been designated Extra Edge(tm) High Protein soybeans, and five are Extra Edge High Oil soybeans. The Extra Edge soybean portfolio characterizes products that offer high levels of oil or protein, and meet recommendations from the United Soybean Board, which encourages growers to choose soybeans that fit processor needs.

"By starting with the superior genetics of NK® Brand soybeans and adding Syngenta insect, disease and weed management options, growers have access to real productivity solutions that deliver higher yield and more profit," Leifker says. "Plus, NK provides bulk options for increased efficiency, including the industry-leading TruBulk® soybean seed delivery system."
