Bulk density is the property of soil which depends on porosity and soil structural conditions. In general it increases with profile depth, changes inorganic matter content, porosity and compaction. The main objective of this study was to investigate the relation of bulk density with other soil characters under the polyhouse soils in mid-hill zone of Himachal Pradesh. The relationships of bulk density (pb) with porosity, particle density, ph, electrical conductivity (EC), CEC, organic carbon (OC) content, total macro-and micro-nutrient content was studied in the soil samples taken from a depth of 0–15 cm from the three districts of Himachal Pradesh. Soil bulk density showed significant negative relationship with porosity and OC but non-significant negative correlation with pH, macroand micro-nutrients. Particle density and EC were positively correlated to bulk density.
