黄土高原地区农田生态系统植物（地上地下）主要生源要素（有机碳、全氮、全磷和全钾）数据集(2015)

本数据集针对黄土高原农田典型分布区域，包括黄土丘陵区庄浪县、关中平原区武功县、银川平原区平罗县、风沙区准格尔旗，测定了以上典型县域农田作物全氮、全磷、全钾、有机碳的含量，建立了黄土高原农田土壤生态系统土壤主要生源要素数据库，编制完成“黄土高原地区农田生态系统植物（地上地下）主要生源要素（有机碳、全氮、全磷和全钾）数据集”。该数据集包括一个数据表，121条记录，主要采用野外采样及室内测定等方式获取数据。数据完全开放共享。

This dataset focuses on the typical farmland distribution areas of the Loess Plateau, including four typical counties and banners: Zhuanglang County in the loess hilly region, Wugong County in the Guanzhong Plain area, Pingluo County in the Yinchuan Plain area, and Zhunge'er Banner in the wind-sand region. We measured the concentrations of total nitrogen, total phosphorus, total potassium, and organic carbon in farmland crops from these regions, and established a database of major soil biogenic elements for the Loess Plateau's farmland soil ecosystem. The "Dataset of Major Biogenic Elements (Organic Carbon, Total Nitrogen, Total Phosphorus, and Total Potassium) in Plants (Aboveground and Belowground) of Farmland Ecosystems in the Loess Plateau Region" has been compiled. This dataset includes one data table with 121 records, and the data was primarily collected via field sampling and laboratory analysis. The dataset is fully open and freely shared for public access.
