The recent development of portable X-ray fluorescence spectrometers (PXRF) has created new avenues for rapid plant elemental concentration determination at reduced cost while avoiding hazardous chemicals. A few studies have indicated the potential use PXRF homogenous tissue analysis. However, there is a lack information analysis heterogeneous samples like livestock forage, which consists mixture several species and parts, each varying in concentration. Our objective was to evaluate forage...
Freshwater forested wetlands account for ~76% (918 M ha) of the total global wetland extent. However, freshwater are difficult to distinguish from upland forest due canopy coverage, abundance wetland-nonwetland mosaics, seasonal hydropatterns, and fewer readily observable connections large surface water bodies relative marshes other emergent habitats. Therefore, ecosystems often misclassified as forests in carbon accounting models, underestimating soil organic (SOC) storage. This study...
Abstract Manure elemental composition determination is essential to develop farm nutrient budgets and assess environmental risk. Portable X‐ray fluorescence (PXRF) spectrometers could facilitate hazardous waste‐free, rapid, cost‐effective concentration determinations. However, sample moisture a problem for by methods. The objective of this study was quantify the effect content, predict correct on determinations in livestock manure. Oven‐dried manure samples ( n = 40) were ground adjusted...
Sediment deposition in coastal wetlands is key to maintaining marsh elevation during periods of sea level rise. Deposition occurs naturally storms increase or when dredged sediments are intentionally introduced restoration build capital. The containing iron sulfide compounds (FeS and FeS2) under natural managed scenarios alters biogeochemical cycles, including the potential induce dramatic declines soil pH prolonged oxidizing conditions. This 20-week mesocosm study investigated FeS FeS2...
Abstract The Mississippi River Deltaic Plain experiences high relative sea level rise, limited sediment supply, and marsh edge erosion, leading to the substantial coastal wetland stored soil organic matter (SOM) loss. objective of this study was understand SOM accumulation rates over past 1000 years related changes in depositional environment these highly eroding wetlands. Soil cores (2 m) were collected from four sites Barataria Basin, LA analyzed for proportion mineral matter, total C, N,...
