a. Data content (data file/table name, including observation index content)

Data file name: Long term positioning observation dataset of soil moisture at Helen Station (1959 1990 1990 1994 2003)

Contains 4 tables: Excel

(1) Moisture characteristic curve dataset

(2) Crop Water Consumption Dataset

(3) Farmland black soil moisture and wheat growth dataset

(4) Farmland black soil moisture and soybean growth dataset

This includes indicators such as soil moisture content, water column height, evaporation, transpiration, water consumption intensity, transpiration intensity, evaporation intensity, water consumption, water demand, soil water supply, yield, water consumption coefficient, water production efficiency, irrigation amount, soil moisture content, bulk density, porosity, precipitation, leakage, interception, transpiration efficiency, transpiration coefficient, assimilation, etc.

b. Construction purpose

Study soil water transport in the soil crop system and promote efficient utilization of soil water in farmland.

c. Service object

Students, managers, and researchers engaged in research related to soil moisture movement in farmland.

d. Time range of data

The data was collected from 1959 to 1990, 1990 to 1994, and 2003

e. The spatial range and projection method of data

Helen's long-term positioning experimental station.
