Abstract:
The research was undertaken to study different land-use system prevailing in sub-humid northern Zone-I of Bihar on soil properties. Five representative land-use was selected and a composite soil sample was made from four soil depth (0-15, 15-30, 30-45, 45-60 cm). Statistical analysis two way (ANOVA) was applied, land-use and soil depth effect on various soil properties. The analyzed data revealed that soil texture analysis sand, silt and clay fraction in different land-use was found non-significant as texture is inherent property and it does not change over small period of small time. Soil organic carbon (SOC) was found to be significantly affected by land-use and ranged 5.55 to 2.98 (g kg^-1). SOC was found to affect positively superior soil properties in land-use having higher carbon in soil. Bulk density varied from 1.41 to 1.46 Mg m^-3 while pH (7.91 to 8.23) and EC (0.48 to 0.34 dSm^-1) in different land-use system. Soil penetration resistance (Pr) ranged (1368.2 to 974.2 KPa) and MWD varied from (3.73 to 2.73mm) among different land-use. Among all land-use selected horticulture land-use was found superior over rice wheat and uncultivated land-use. Mango land-use was found superior over litchi land-use. The data from research suggest that horticultural land-use may be recommended in areas having poor soil properties which will enhance soil quality and sustainability of soil.
