| Abstract/Contents: | "Organic and slow-release fertilizers generally result in less nitrate leaching losses than synthetic soluble fertilizer formulations. There is also some literature reporting greenhouse gas (GHG) emissions consisting of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4) from turfgrass sites. However, there is no clear trend in the few published studies that would consistently indicate less GHG emissions with the slow-release synthetic fertilizers compared with GHG emissions from soluble synthetic fertilizers. Moreover, some speculate that synthetic fertilizers are detrimental to beneficial soil microbial populations, and result in the increase of harmful pathogens. The objective of this study was to evaluate the relationship between slow-release organic and synthetic nitrogen sources on greenhouse gas emissions and the soil microbiome. This field study was established in 2018 on an existing tall fescue turf managed as a lawn with plots that have received an all-natural organic fertilizer or a slow-release synthetic fertilizer yearly since 2008. In addition, a non-fertilized control plot was included. Rates for both fertilizers were 49, 98, 147, and 196 kg N ha-2, applied in split-applications (Jun. and Oct.). Gas was collected monthly from static chambers placed in the plots from June through October, two weeks after fertilizer applications. Gases were analyzed for concentrations of CO2, N2O, and CH4 using a gas chromatography. Rhizosphere microbiome was characterized from soil samples collected before fertilization and at the same time as Jun and Oct. gas sampling. Bacterial and fungal constituents were determined from next-generation sequencing and analysis of 16S and ITS rDNA, respectively. Additionally, CO2 respiration will be estimated with the Solvita soil CO2-Burst test, and soil labile amino nitrogen will be estimated with the Solvita SLAN test. Data will be statistically analyzed to determine if differences exist between the fertilizer types, rates, or the interaction between fertilizer types and rates." |
