An investigation was carried out at LTFE, Farm, IGKV, Raipur(C.G) in order to study the influence of long term application of balanced and imbalanced fertilization on different soil physical properties under rice-wheat cropping system during kharif-2018. BD, hydraulic conductivity, soil moisture content (gravimetric and volumetric), total porosity and soil temperature significantly improved with the combined use of inorganic fertilizer along with FYM. The soil (cone) penetration resistance was found higher at the maturity stage than flowering stage of rice. The lowest value of BD 1.13m-3 was achieved at depth of 0-5cm due to application of 100% NPK+FYM, while the application of 100% NPK + FYM resulted in highest HC (1.2 cm hr-1), gravimetric moisture content (23.5%) and the total porosity (57.2%). The volumetric moisture was found highest in 100% NPK + FYM and 150%NPK treatment at the depth of 15-20cm (32.8%).The lowest soil temperature was found in treatment 100%NPK + FYM (16.40C). The PR was significantly lower 2.26 kN cm-2 in 100%NPK+FYM at the depth of 5cm in the flowering stage of rice crop. The positive significant correlations were observed between various soils physical properties, whereas BD was found negatively correlated except with soil temperature. Similarly, soil temperature is negatively correlated with all physical indices but BD. The present investigation shows the significance of balanced use of fertilizers along with FYM for improving various soil physical properties over long term conditions.
