1. Polymer Coated Urea Impact on Barley Yield and Protein Polymer coated urea (PCU) is an enhanced efficiency nitrogen (N) fertilizer shown to regulate N release over a season benefiting production and reducing nutrient pollution. The purpose of this study was testing the effect of uncoated and coated urea blends on irrigated barley yield and protein. The study consisted of three N rates applied as all urea or a 50-50 blend of PCU and urea. As expected, N rates increased yields and protein. In general, urea resulted in increased yields with... S.

2. Spectral Response of Pulse Crops to Soil Acidity for Soil pH Mapping In this work, we explore the observable differences in the spectral reflectance of pulse crops in acidified and non-acidified soil regions of multiple Montana fields. Satellite observations are collected throughout the growing season using Landsat 8 & 9 and Sentinel 2 A & B. The variations of crop reflectance in acidified (pH < 5) and non-acidified (pH 6.0 to 7.0) are analyzed and used to support why both multi-temporal regression and machine learning models are... P.
