Managing Soil Ph For Crop Production In Calcareous-Alkaline Soil, Cody Zesiger, Jody Gale, Matt Yost, Grant Cardon

All Current Publications

In semiarid soils of the Western U.S., altering soil pH is not easily accomplished nor straightforward. Utah’s soil pH range can be 1,000 times more acidic or alkaline than neutral (7.0) pH soils. In semiarid regions, typical high-pH soils are also calcareous, meaning there is a large amount of solid calcium carbonate (lime) in the soil. When soil-acidifying amendments are added to these soils, the lime dissolves and counteracts any of the applied soil-acidifying amendments. This fact sheet explains how to identify whether crop symptoms are related to soil pH, how to perform an in-field test for soil pH buffering …

Theses and Dissertations

This study examined the effects of wet aging on water-soluble flavor compounds, descriptive flavor, consumer acceptability, and willingness-to-pay of beef strip steaks. Twenty USDA Select boneless beef loins (NAMP #180) were dorsally divided into four equal portions, which were randomized to receive either 0, 7, 14, or 21 d of wet aging. Short-chained peptide concentration increased from 4.11 mg/g on d 0 to 5.12 mg/g on d 7 (P = 0.011) and subsequently increased to 7.14 mg/g on d 21 (P < 0.001). Cooked beef contained 1.85 mg/g less short-chained peptides than raw beef (P < 0.001). Wet aging for 21 d increased the concentrations of amino acids, which are precursors for the Maillard reaction, including methionine, threonine, cystine, serine, tryptophan, and phenylalanine (P < 0.001). Wet aging decreased the nucleotide concentrations (P ≤ 0.003) and increased hypoxanthine concentration, a compound that imparts bitter flavor (P …
