1. Soil Analysis Methods Accuracy and Precision Comparison: Historical North American Proficiency Testing (NAPT) Program Results The SSSA-NAPT Program provides open access to soil, water, and plant laboratory data. This data is collected quarterly from about 150 participating laboratories. For soil data, five samples are sent to participant laboratories for them to submit data for any or all of the 99 accepted methods. Our objective was to evaluate data precision from 43 soil samples (2019-2021). A measure of precision was made by dividing the Median Absolute Deviation (MAD) by the Median for each of the 43 samples... B.G. Hopkins, G.E. Cardon, J.R. Lawley Download paper
2. Effect of Soil and Foliar Application of Sulfur, Magnesium, Boron, and Zinc on Root Yield and Sugar Quality in Conventional Till and No Till Sugar Beet Field experiment was conducted at the Eastern Agricultural Research Center in Sidney, MT, to determine the effect of S, Mg, B, and Zn on beet yield and sugar quality under conventional and no-till system. Split-plot design was used with 3.6 x 9.1 m experimental plots and four replicates. Tillage was main plot and micronutrient fertilizer was sub-plot. Tillage treatments included conventional and no-till. Fertilizer treatments included SUL4R-PLUS® (Ca & S), SUL4R-PLUS®B+Zn... C. Lim, C. Chen, C. Kowatch-carlson, B. Franck, T. Gross, R.
