1. Dramatic Soil Health Changes After 18 Years of Different Nitrogen Rates and Cropping Systems in the Northern Great PlainsRelatively few long-term cropping and nitrogen rates studies have been conducted in the semi-arid northern Great Plains that assess soil health changes. A cropping system study was initiated in 2002 in Bozeman, Montana (~400 mm annual precipitation) with wheat grown in even years, and either tilled fallow or one of the following no-till systems in odd years: fallow, wheat, pea grain, pea hay, pea green manure, and an alfalfa-grass (until 2012) followed by pea grain. N was applied at either 50%... C. Jones, P. Miller, C. Zabinski, W. Fouts |
2. Effect of Seeding Rate on Annual Warm Season Forage Yield and Plant StructureDue to the decline of the Ogallala Aquifer and reduced irrigation capacity, there is growing interest in more water-efficient cropping systems in the semi-arid central Great Plains. To support the region’s livestock industry, there is increased interest in forages because they use water more efficiently than grain crops. However, there is insufficient information on summer annual forage seeding rates in the range of environments encountered in the region. The objective of this study was... J. Holman, N. Detter, A.
