Abstract
The Quick Wash (QW) treatment extracts phosphorus (P) from manure and municipal sludge (MS), producing an organic acidified by-product with adequate nitrogen (N):P ratio to meet crop N requirements. Yet, data on crop response to N using QW by-products are lacking. We evaluated the response of annual ryegrass (Lolium multiflorum Lam.) and potential N leaching in sandy soil to N applications using raw wastes, their corresponding QW by-products, and ammonium sulfate (AMS) fertilizer. Treatments included a control (no amendment added), raw and acid-washed chicken litter, dairy and swine manure, MS, and AMS at 100, 200, and 400 kg N ha−1.

Data reported in xlsx file are used in the article, "W.S. Paye, A.A. Szogi, P.D. Shumaker, and E.D. Billman, 2023. Annual Ryegrass (Lolium multiflorum Lam.) growth response to nitrogen in a sandy soil amended with acidified manure and municipal sludge after "Quick Wash" Treatment. Agronomy, 13, 2655.
Description of the data and file structure
The data file "2023_11_21_Ryegrass Dataset.xlsx" is an Excel spreadsheet consisting of multiple sub-tabs associated with tables 1-6 in our related journal article. Tabs associated with Table 1, 4, 5, and 6 include our measured data and explanation of these data follows this paragraph. The tab associated with Table 2 is data calculated from data measured and reported in tab "Table 1". Tab "Table 3" includes statistical parameters from an analysis of variance or our measured data. Tabs "Table 2" and "Table 3" have text boxes explaining that data in these tables are calculated using measured data from other tables in the manuscript. Each tab has a key to explain what abbreviations mean within the data labels.
The "Table 1" tab includes data associated with the characterization of the soil amendments applied to the soil in our experiment. These data include the initial pH, carbon, nitrogen, and phosphorus content of the chicken litter, Quick Washed chicken litter, dairy manure, Quick Washed dairy manure, municipal sludge, Quick Washed municipal sludge, swine manure, Quick Washed swine manure, and ammonium sulfate we evaluated as nitrogen sources for annual ryegrass growth. This table also includes a carbon to nitrogen and nitrogen to phosphorus ratio for each soil amendment which are calculated from the measured carbon, nitrogen, and phosphorus contents of the materials tested.
The "Table 2" tab is included because the table is present in the peer-reviewed publication, however the data presented are application rates of soil amendments and nutrients calculated from measured data presented in the "Table 1" tab., it includes no measured variables and is not part of data re-use.
The "Table 3" tab is included because the table is present in the peer-reviewed publication, however the data presented are statistical parameters, it includes no measured variables and is not part of data re-use.
The "Table 4" tab includes data related to the mass of annual ryegrass harvested from the experimental pots with soil amendments applied at targeted nitrogen rates (Biomass Yield) and the nitrogen removed from the soil system by the biomass harvested from the pots (N Uptake). Each pot was planted with ryegrass following amendment application, the ryegrass was grown for a total of 70 days, and ryegrass biomass was harvested four separate times at 20, 35, 50, and 70 days after planting. The biomass yield is the sum of the mass of plant material harvested in these four harvests. The nitrogen uptake is calculated from the nitrogen content of the ryegrass harvested at each harvest date and the biomass harvested.
The "Table 5" tab includes data related to leaching the soil in the pots with 1 liter of water and measuring the ammonium and nitrate concentrations in the free drained leachate. This was performed to evaluate the potential movement of nitrogen into groundwater resources after application of the experimental soil amendments and subsequent annual ryegrass growth and harvest.
The "Table 6" tab includes data related to inorganic nitrogen forms still in the soil system after the 70 day annual ryegrass growth, harvest, and subsequent leaching of the soil system with one liter of water. Ammonium and nitrate concentrations were measured in potassium chloride extractions from composite soil samples from all of the experimental pots and summed to calculate Soil Inorganic Nitrogen concentration.
Any cell with a "-" in this dataset (e.g. tab "Table 1", cell B18) indicates this variable was not measured, therefore no data is included in this dataset or in the published manuscript.
Any cell with a "." in this dataset (e.g. tab "Table 5", cell E20) indicates a data point measured below our detection limit and was excluded from the statistical comparisons of our experimental treatments.
