黄土高原地区农田生态系统土壤主要生源要素（有机碳、全氮、全磷和全钾）数据集(2011-2015)

农田土壤碳、氮、磷、钾含量是旱地农业土壤质量的直接提现。本研究针对黄土高原农田典型分布区域，包括黄土塬区宁县、黄土丘陵区庄浪县、关中平原区武功县、银川平原区平罗县、风沙区准格尔旗以及汾河谷地一带，测定了以上典型县域农田土壤全氮、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“黄土高原地区森林、草地和农田生态系统土壤主要生源要素（有机碳、全氮、全磷和全钾）数据集--农田生态系统”。该数据集包括一个数据表，898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。

Soil carbon, nitrogen, phosphorus and potassium contents in farmlands directly reflect the soil quality of dryland agricultural systems. This study focused on typical farmland distribution regions on the Loess Plateau, including Ning County in the Loess Tableland Region, Zhuanglang County in the Loess Hilly Region, Wugong County in the Guanzhong Plain Region, Pingluo County in the Yinchuan Plain Region, Zhungeer Banner in the sandy area, and the Fen River Valley area. We measured the concentrations of total nitrogen, total phosphorus, total potassium and organic carbon in farmland soils of these typical counties, established a database of key soil biogenic elements for farmland soil ecosystems on the Loess Plateau, and completed the compilation of the dataset "Dataset of Key Soil Biogenic Elements (Organic Carbon, Total Nitrogen, Total Phosphorus and Total Potassium) of Forest, Grassland and Farmland Ecosystems on the Loess Plateau - Farmland Ecosystem". This dataset contains one data table with 898 records, and the data were mainly acquired via field sampling and laboratory analysis. The data are fully open and freely available for sharing.
