2026-01-08 Soil Fertility Evolution dataset of arable land in Guanzhong Plain of Shaanxi Province from 1980 to 2022 doi:10.57760/sciencedb.j00001.01652 en This dataset consists of one data file and two tables, which are “Sample point information” and “Soil properties”. The table of “Sample point information” records the codes of sample point, name, and administrative, longitude and latitude, a total of five fields and 3195 pieces of data. The “Soil properties” table records the code and name of sampling point, soil organic matter, total nitrogen, total phosphorus, total potassium, alkali-hydrolysable nitrogen, mineral nitrogen, available phosphorus, available potassium, pH, cation exchange capacity, calcium carbonate, available iron, available manganese, available copper, available zinc, available boron, bulk density, porosity and data sources, a total of 23 fields and 3195 pieces of data.
