Résumé
Agricultural-based economies are struggling to remain sustainable because of the challenges facing agriculture, including global market realities, decreasing market prices, and increasing input costs. This is especially true in the Mon-Dak region (western North Dakota and eastern Montana), which because of its geography and climate, has few other business opportunities.Insufficient water is the most common limiting factor for crop growth in the region. This research is seeking to develop non-irrigated and irrigated agronomic management practices that reduce water loss and increase the amount of crop yield produced per volume of water.No-till farming systems conserve soil and water but can increase the acidity level of topsoil. This research is seeking economically viable methods to reduce topsoil acidification in no-till systems by the use of agricultural lime and acid-tolerant crop varieties. Increasing crop diversity is an essential aspect to restore and maintain soil health. In cool semi-arid regions, both short growing seasons and limited water availability are constraints to growing many crops. This research is looking at "intercropping", i.e., growing two cash crops simultaneously in a single field, as a means to increase crop diversity, land use efficiency, and market diversification.Poor soil water management can result in the excessive accumulation of naturally-occurring salts in the soil, which can adversely affect crop growth. This project will demonstrate how improvements in soil water management can remediate the occurrence of excessive soil salinity.The development of productive, profitable, and sustainable dryland and irrigated cropping systems addressing the soil and water limitations of the area is essential if farmers of the Mon-Dak region are going to compete in world markets.

Objectifs
Increase the economic sustainability of crop agriculture in western North Dakota and eastern Montana by addressing the issues of water scarcity, acidic topsoil, limited crop diversity, and soil salinity.OBJECTIVES:1. Determine the effect of crop diversification, agronomic practices, and irrigation management on water use efficiency in no-till systems.2. Investigate methods to remediate fertilizer-induced topsoil acidification in dryland no-till systems.3. Investigate intercropping as a means to increase crop diversification in western North Dakota.4. Demonstrate the remediation of saline seeps by improved water management in the recharge area.
