Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Kansas Agricultural Experiment Station Research Reports

Phosphorus (P) fertilizer additions are often required to meet crop nutrient demands, but over-fertilization can have economic consequences, as well as environmental consequences from agricultural P loss. Therefore, we require management strategies that balance crop P demand and the need to minimize environmental P loss. The objective of this study was to investigate the effect of cover crop addition and P fertilizer management strategy [build and maintain (BM), sufficiency (SF), and a zero-P control (CN)] on crop yield of a no-till, corn-soybean system for 2020, 2021, and 2022 crop years for a site near Manhattan, KS. The addition of a …

Kansas Agricultural Experiment Station Research Reports

Previous work suggests that wheat can respond to chloride fertility in Kansas and other regions, but this response depends on Cl availability and the wheat variety. In this study, we aimed to identify and quantify the effects of chloride fertilizer application in different areas and winter wheat varieties across Kansas. Sixteen field experiments were conducted during the 2021–2022 growing season. All experiments were conducted in a split-plot design with Cl fertility levels as whole plot (0 or 20 lb Cl/a) and wheat variety as subplots, with either three or four replicates. One protocol evaluated 24 winter wheat varieties in three …
