Soil penetration resistance (SPR) is one of the major indicators soil physical properties. Crop residue managements, tillage practices and their interactions exert significant effects on SPR. However, rare information available in sloping farmland Mollisols. Field experiments were conducted to investigate variations SPR as affected by crop managements land Northeast China from 2015 2019. The sp...
Optimum biochar preparations enhance phosphorus availability in amended Mollisols of Northeast China
In order to study land degradation from the soil genesis and micromorphological perspective, ten soil profiles were dug and described on five slope positions in both forest and deforested cultivated land. The soil samples were taken from all horizons for physico-chemical analysis and micromorphological studies. Forest soils had a well developed argillic and calcic horizons and also mollic epipe...
Mollisols include an abundance of soil organic carbon (SOC) which is easily influenced by fertilization management. Manure addition could enhance aggregate stability; however, the dominating factor affecting its stabilization remains controversial. The practices were initiated in 2012 to investigate influences different managements on contents and molecular characterization (OC) fractions, clar...
