WAT05 Soil organic matter response to thirty years of increased precipitation at Konza Prairie

This dataset contains carbon and nitrogen concentrations and stocks in total soil organic matter and its fractions from the Konza Prairie Irrigation Transect Experiment. The dataset also includes pyrogenic organic matter C and N, as well as microbial amino sugars and root quality measurements. Data are availble for irrigated and control plots. Total pyrogenic and unburned soil organic matter C and N are availble for both the upland and lowland positions at 0-5, 5-15, and 15-30cm depth increments. Fraction and root data are avaible at both landscape positions, but for only the 0-5cm and 5-15cm depths and 0-5 and 5-30cm depths, respectively. Amino sugar data are only available for the lowland plots for the 0-5 and 5-15cm depths.

本数据集收录了康扎草原灌溉样带试验（Konza Prairie Irrigation Transect Experiment）中土壤总有机质及其各组分的碳、氮浓度与储量数据，同时涵盖热解有机质（pyrogenic organic matter）的碳、氮含量，以及微生物氨基糖与根系品质测定数据。数据覆盖灌溉组与对照组样地：针对高地与低地两种地貌位置，均采集了总热解有机质及未燃烧土壤有机质的碳、氮数据，采样土层深度梯度为0-5cm、5-15cm及15-30cm；组分与根系相关数据覆盖两种地貌位置，但分别仅对应0-5cm、5-15cm土层，以及0-5cm、5-30cm土层深度；氨基糖数据仅覆盖低地样地的0-5cm与5-15cm土层。
