A dataset of red soil temperature dynamic from the long-term fertilization experiment at Qiyang Station from 2020 to 2022

This dataset is presented in the form of an Excel file, which contains 9 sheets. The specific naming and detailed information of each form are as follows: The "Trial Site Information" sheet records the specific site-related information for the trial, including field name, geographical location, altitude, and other fields, providing basic geographical information background for the entire dataset. The "Soil Basic Properties Before Trial" sheet covers the basic soil property data from 1990 before the start of the long-term fixed-location trial, such as soil pH value, organic carbon, nitrogen, phosphorus, and potassium content, reflecting the basic state of the soil at the start of the trial. The "Trial Design" sheet records the trial design scheme, including key information such as treatment description, fertilizer application rate, and whether straw is returned to the field or not, serving as an important basis for understanding the overall trial structure and different treatment settings. The "Soil Temperature Raw Data" sheet records the raw soil temperature data at half-hour intervals by WatchDog 2900ET monitoring device, including fields such as recording time (accurate to minutes), trial treatment, and soil temperature. This sheet contains a large amount of data, providing detailed and accurate raw soil temperature information for subsequent analysis. The "Soil Temperature" sheet records soil temperature data from January 1, 2020, to December 31, 2022, and is associated with the "Soil Temperature Raw Data" sheet and other related sheets through fields such as "Date" and "Treatment". This sheet data is the result of sorting and summarizing the raw data, facilitating users to quickly obtain soil temperature information within a specific time period. The "Local Meteorological Data" sheet records daily meteorological data (from January 1, 2020, to December 31, 2022) corresponding to the soil temperature data, including fields such as time, temperature, relative humidity, precipitation, wind direction, wind speed, dew point temperature, and solar radiation. It is associated with the "Soil Temperature Raw Data" sheet and the "Soil Temperature" sheet through the "Date" field, facilitating the analysis of the impact of meteorological factors on soil temperature. The "Soil Temperature, Humidity, and Electrical Conductivity" sheet records soil temperature, humidity, and electrical conductivity data at different time points from December 8, 2020, to October 28, 2021, including fields such as date, temperature, moisture, and electrical conductivity. It is associated with other related sheets through fields such as "Date" and "Treatment", aiding in the study of changes in the soil environment during the specific period. The "Soil Fertility and Crop Traits" sheet records data on soil nutrient content such as nitrogen, phosphorus, and potassium, as well as wheat and corn yield, plant height, and 1000-grain weight traits. It is associated with other sheets through fields such as "Year" and "Treatment", and can be used to analyze the relationship between soil fertility and crop traits. The "Field Description" sheet records the definition, units used, and specific measurement methods for each field. It establishes associations with other related sheets through "Sheet Name" and "Field Name", enhancing the comprehensibility and usability of the dataset, and facilitating users' querying, analysis, and research of data from different perspectives.
