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观测数据。该数据集的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年的实收产量与归一化产量、土壤质地特征参数（有机质含量、孔隙度、容重、粒径指标、砂粒/粉粒/粘粒百分占比）、多类地下水位深度指标（均值、百分位数、超阈值累计值、移动平均值），以及通过Rosetta土壤传递函数（Rosetta pedotransfer function）估算得到的土壤持水参数。本数据集为Zipper等（投稿待刊）开展的一项研究的组成部分，该研究探究了Wibu试验田内地下水位深度、土壤质地以及作物生育期气象条件对玉米生产的影响。Wibu试验田为商业化农田，2012、2013及2014年的作物生育季均种植玉米。有关该试验田的更多详细信息，可参阅Zipper与Loheide于2014年发表在《农业与森林气象学（Agricultural and Forest Meteorology）》的相关研究成果。
