1. Measured and Predicted Temporal Changes in Soil Nitrate-n Levels from Late Summer to Early Spring in Montana Most soil sampling is conducted from August to November in Montana because of better soil sampling conditions and because it provides more time for growers to make fertilizer decisions prior to application. Fertilizer guidelines in Montana are based on spring nitrate-N levels in the upper 2 ft because they are more indicative of growing season available N than fall nitrate-N levels. It is not known how much nitrate-N levels change between late summer and spring, nor is it known what factors affect... C. Jones, A. Lenssen, C. Chen, K. Mcvay, B. Stougaard, M. Westcott, J.

2. Impact of an Enhanced Nitrogen Fertilizer (ESN) on Irrigated Crop Production in South Central Montana Trials were conducted at the Montana State University Southern Agricultural Research Center in Huntley, MT using ESN (44% N, Agrium Advanced Technologies) in combination with urea (45% N) on three different irrigated crops: spring wheat, corn, and sugar beet. Each experiment was a randomized complete block with 4 replications using either 4 or 6 nitrogen rates in combination with 6 or 4 mixing ratios of ESN:urea, plus one unfertilized check for a total of 25 treatments. Urea and ESN were weighed... K. Mcvay, K. Kephart, Q. Khan
3. 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. Miller, K. Olson-rutz
4. Ammonia Recovery from Anaerobically Digested Dairy Wastewater Facilitated by In-situ Acid and Base Generation in a Transmembrane Electro-chemisorption System Nitrogen (N) is essential for living organisms and is a critical element in agricultural production. Ammonia (NH₃), a vital component in the nitrogen cycle, can be produced naturally by nitrogen-fixing bacteria or artificially through the energy-intensive Haber-Bosch process. Anaerobically digested dairy wastewater (ADDW) could contain high concentrations of ammonia nitrogen (NH3-N) due to the conversion of organic N into NH3-N during the anaerobic digestion process. Ammonia... A.K. Das, L. Chen
