    State were studied. Clay content was the highest in soils of forest profiles, followed by those under cultivated unmanaged and well-managed profiles, and least in soils of barren land profiles. Soils of barren lands showed the highest values of bulk densitybulk densitySubject Category: Properties

    (1.47 to 1.60 g cm-3), followed by cultivated unmanaged (1.46 to 1.58 g cm-3), cultivated well-managed lands (1.34 to 1.54 g cm-3), and least in those of forest lands (1.32 to 1.52 g cm-3). The values of particle densityparticle densitySubject Category: Properties

    decreased in the order: barren lands (2.57 to 2.68 g cm-3) > cultivated unmanaged (2.52 to 2.67 g cm-3) > cultivated well-managed (2.44 to 2.62 g cm-3) > forest lands (2.38 to 2.62 g cm-3). Soils of forest lands had generally higher values of pore space (41.4 to 47.2%) followed by cultivated well-managed lands (41.4 to 45.1%), barren (40.1 to 43.4%) and unmanaged cultivated lands (40.0 to 43.2%).

    (%) ranged from 21.9 to 32.2, 30.5 to 40.5, 35.4 to 47.5 and 35.3 to 47.3 in soils of barren, cultivated unmanaged, cultivated well managed and forest lands, respectively. Soils of forest lands showed highest values of moisture equivalent (23.4%) and lowest in those of barren lands (15.7%), while there was not much difference in the moisture equivalent values of soils belonging to cultivated unmanaged (21.5%) and cultivated well-managed (22.9%) lands.
