Introduction Corn and soybean planting is one of the most critical operations of the season. Operating the planter with the proper soil conditions for proper placement of the seed to obtain the correct seed-soil contact is important to optimize yields and reduce problems later in the season with plant and root growth. As corn and soybean seed prices continue to rise, and grain prices fall, it i...

For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...
