1. Soil Acidification: Identification, Prevention, Adaptation and Restoration Low soil pH is becoming far more common in Montana soils, with at least 23 counties having at least one field with pH less than 5.5. Soil pH levels in the top 6 inches as low as 3.8 have been measured, resulting in complete crop failure insome locations, yet the problem is highly variable across fields and within soil profiles. Nitrogen fertilizer rates applied above crop nitrogen needs are the largest cause of the acidification. Low soil pH should be verified before managementpractices... C. Jones, R. Engel, S. Ewing, P.

2. Utilizing the 4Rs to Mitigate Ammonia Toxicity in Roots The banding of nutrients below the seed row is a common practice in dryland agricultural settings. However, banding below the seed row has been shown to hamper stand establishment and damage seedling root growth in a number of studies. The research presented here uses a novel and inexpensive imaging technique to assess the rate and source management options for reducing root damage when banding N fertilizers below the seed at planting. Survival analysis was conducted on canola... I. Madsen, W. Pan
3. Development of a Constrained Resource Model to Support Intercropping Decisions Crop producers are interested in intercropping due to its’ potential to increase profitability, yield stability and sustainability. Our objective was to extend a simulation model to forecast crop yields (PRS® CropCaster®) to pulse-oilseed intercrops. This tool would provide crop producers with forecasts of yields of each crop component under different management and environmental conditions. Based on competition for fertilizer 15N... E.

4. On-Farm Variable-Rate Nitrogen Management in Potato Applying variable nitrogen (N) has often improved yields, quality, and/or N use efficiency (NUE) of several crops. The objective of this study was to evaluate how pre-emergence variable rate N (VRN) zones vs. uniform N management impacts potato (Solanum tuberosum L.) yield, quality, and NUE. Low, average, and high N zones were created and evaluated for 10 site-years at fields near Grace, Idaho, USA over two years with rates based upon yield goals, soil, water, and previous crop information....
