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

Data file name: Northeast Region Farmland Meadow Soil Moisture Attribute Dataset (1960-1980)

Contains 10 tables: Excel

(1) Moisture dynamic value of clay meadow soil (black loach soil) (0-50cm)

(2) Calculation of wheat water demand and water supply capacity of farmland meadow soil

(3) Calculation of Soybean Water Demand and Water Supply Capacity of Farmland Meadow Soil

(4) Calculation of Corn Water Demand and Water Supply Capacity of Farmland Meadow Soil

(5) Stratified permeability coefficient of clay meadow soil

(6) Meadow soil is abundant, and the water storage status in the soil layer during dry seasons (0-100cm)

(7) Mechanical composition of clay meadow soil (black loach soil)

(8) Physical properties of clay meadow soil (black loach soil)

(9) Alkalinization characteristics of loach type soil

(10) Changes in groundwater level during the high water period (July August) of sticky meadow soil (black loach soil)

It includes indicators such as soil moisture content, mechanical composition, permeability coefficient, water demand, and soil water supply capacity.

b. Construction purpose

Provide data support for the efficient utilization of soil moisture in black soil farmland.

c. Service recipients

Students, managers, and researchers engaged in research on soil moisture cycling and soil ecology in farmland.

d. Time range of data

Data collection period is from 1960 to 1980

e. The spatial range and projection method of data
