Description:
As part of a study identifying relationships between environmental variables and insect distributions within a bioenergy crop, giant miscanthus (Miscanthus x giganteus) samples were collected in October 2016 at 33 locations within a field in southeast Georgia, USA. At each location, one plant sample was collected every meter along a 5-m transect, resulting in 5 replicates per sampling location. The plant samples were separated into leaves and stems, air-dried, weighed, and ground. This dataset describes the chemical composition of giant miscanthus leaves and stems including the total carbon (TC) and nitrogen (TN) content, total macro- and micronutrients (aluminum, arsenic, boron, calcium, cadmium, cobalt, chromium, copper, iron, potassium, magnesium, manganese, molybdenum, sodium, nickel, phosphorus, lead, sulfur, selenium, silicon, titanium, vanadium, and zinc), and the characterization of the water extractable organic matter (WEOM). The TC and TN content was determined directly on ground plant samples using a Vario EL III combustion C-N analyzer. For the quantitation of the total macro- and micronutrient content, the plant material was first digested in trace metal grade nitric acid in a microwave digestion system. The digestate was then analyzed using Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES) on a ThermoFisher Scientific iCAP 7400 Duo. For the characterization of the leaf and stem WEOM, the plant material was extracted in water and the extract was filtered and analyzed using UV-Visible and Fluorescence Excitation Emission Matrix (EEM) spectroscopy on a Horiba Scientific Aqualog spectrofluorometer. The optical data obtained from the EEM scans were used to calculate several indices representative of WEOM quality including the absorbance at 254nm, the absorbance ratios at 254 to 365nm and 280 to 465nm, the slope ratio, the fluorescence index, the humification index, the biological index, and the freshness index. The fluorescence intensity of 5 common fluorescence peaks (peaks A, C, M, B, and T) is also reported. This dataset includes an analytically diverse set of measurements that describe the chemical composition of giant miscanthus leaf and stem tissues. This dataset will be useful for those wishing to identify relationships between the chemical composition of giant miscanthus and pest distributions within a bioenergy crop field.

At each location, one plant sample was collected every 3-4 meters along a 15-m transect, resulting in 5 replicates per sampling location. The plant samples were separated into leaves and stems, air-dried, and ground. The chemical composition of the ground material was assessed by measuring total carbon and nitrogen, total macro- and micronutrients (aluminum, arsenic, boron, calcium, cadmium, cobalt, chromium, copper, iron, potassium, magnesium, manganese, molybdenum, sodium, nickel, phosphorus, lead, sulfur, selenium, silicon, titanium, vanadium, and zinc) using Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES), and optical characteristics of the water extractable organic matter using UV-Visible and Fluorescence Excitation Emission Matrix (EEM) spectroscopy.

注：本版本取代了版本1：https://doi.org/10.15482/USDA.ADC/1523127
数据版本2的变更：版本1中经纬度的值被颠倒，现已更正。新增了包含经纬度（以十进制度数表示）的列。在元数据标签中，对采样描述进行了编辑。
描述：本数据集作为一项研究的一部分，旨在探讨环境变量与生物能源作物中昆虫分布之间的关系，于2016年10月在乔治亚州东南部一个田地内的33个地点收集了巨型Miscanthus（Miscanthus x giganteus）样本。在每个地点，沿5米长的样带每隔1米收集一个植物样本，每个采样地点得到5个重复样本。植物样本被分离成叶片和茎，经空气干燥、称重和粉碎。本数据集描述了巨型Miscanthus的叶片和茎的化学组成，包括总碳（TC）和氮（TN）含量、总宏量和微量元素（铝、砷、硼、钙、镉、钴、铬、铜、铁、钾、镁、锰、钼、钠、镍、磷、铅、硫、硒、硅、钛、钒和锌）以及水溶性有机物（WEOM）的特征。TC和TN含量直接在粉碎的植物样本上使用Vario EL III燃烧C-N分析仪测定。对于总宏量和微量元素含量的定量，植物材料首先在微波消解系统中用痕量金属级硝酸消解。消解液随后在ThermoFisher Scientific iCAP 7400 Duo上使用电感耦合等离子体原子发射光谱法（ICP-OES）进行分析。对于叶片和茎WEOM的特征化，植物材料用水提取，提取物经过过滤，并使用Horiba Scientific Aqualog光谱荧光计上的紫外-可见光和荧光激发发射矩阵（EEM）光谱进行分析。从EEM扫描中获得的光学数据用于计算代表WEOM质量的几个指数，包括254nm处的吸光度、254至365nm和280至465nm的吸光度比值、斜率比、荧光指数、腐殖化指数、生物指数和新鲜度指数。还报告了5个常见荧光峰（峰A、C、M、B和T）的荧光强度。本数据集包括一系列分析测量，描述了巨型Miscanthus叶片和茎组织的化学组成。本数据集对于希望识别巨型Miscanthus化学组成与生物能源作物田地中害虫分布之间关系的研究人员具有重要价值。
