This data set is the soil survey data of vegetation communities in desert grassland and typical grassland in Inner Mongolia Autonomous Region and Ningxia Hui Autonomous Region. This experiment provides basic data for the study of the causes, processes and mechanisms of natural grassland degradation.
Attribute information includes: bulk density, water content, pH value, organic carbon content, clay content, powder content, sand content, total carbon, total nitrogen and carbon nitrogen ratio.
Unit weight: the weight per unit volume is called unit weight, and the formula is γ= G / V (n / m3), unit weight is equal to the product of density and gravitational acceleration, i.e γ=ρ g。
Moisture content: the moisture contained in 100g dried soil.
PH value: soil pH.
Organic carbon content: the content of organic C in soil.
Clay content: determined by laser particle size method.
Powder content: determined by laser particle size method.
Sand content: determined by laser particle size method.
Total carbon: the total amount of carbon in the soil.
Total nitrogen: the total amount of nitrogen in the soil.
Carbon nitrogen ratio: total carbon in soil / total nitrogen in soil.
All kinds of data are collected manually.
The mechanical composition of soil was determined by laser particle size method.
All data are checked within the allowable value range, and the data is relatively accurate.
