WSC - Gridded sample points at Wibu field site including yield, soil texture, water table depth, and estimated soil water retention parameters

A variety of data from gridded sampling points at the Wibu field site. The gridded sampling scheme is described in the Point Locations dataset. This dataset includes 2012 and 2013 absolute and normalized yield, soil textural characteristics (organic content, porosity, bulk density, particle size metrics, % sand/silt/clay), a variety of water table depth metrics (mean, percentiles, sum exceedance values, moving averages), and soil water retention parameters estimated using the Rosetta pedotransfer function. It was collected as part of a study of the impacts of water table depth, soil texture, and growing season weather conditions on corn production at the Wibu field site, described in Zipper et al. (in review). The Wibu field site is a commercial agricultural field, which grew corn in the 2012, 2013, and 2014 growing seasons. See Zipper and Loheide (2014) Ag. For. Met. for more information about the field site.

本数据集包含Wibu试验田网格化采样点的多类数据。其网格化采样方案详见《点位数据集（Point Locations dataset）》。本数据集涵盖2012年与2013年的绝对产量、归一化产量数据，土壤质地特征参数（包括有机质含量、孔隙度、容重、粒径指标、砂粒/粉粒/黏粒占比），多类地下水位埋深指标（均值、百分位数、超量总和值、移动平均值），以及采用罗塞塔土壤传递函数（Rosetta pedotransfer function）估算得到的土壤持水参数。本数据集采集自一项针对Wibu试验田地下水位埋深、土壤质地与生育期气象条件对玉米生产影响的研究，相关研究详情见Zipper等人（待刊）的成果。Wibu试验田为商业化农田，2012、2013及2014年均种植玉米。如需了解该试验田的更多信息，请参阅Zipper与Loheide（2014）发表于《农业与森林气象学（Agricultural and Forest Meteorology，简称Ag. For. Met.）》的研究论文。
