EFFECT OF COMPACTION, RICE HUSK/SAW DUST AND MOISTURE CONTENT ON BULK DENSITY AND PENETRATION RESISTANCE OF CLAY SOILS (VERTISOLS)
Two organic materials (rice husk, saw dust) at three different levels of treatment were separately incorporated into clay soil and then compacted at three moisture content levels using four compactive efforts. The three organic matter and moisture content levels were 4%, 6%, and 8% and 20%, 35%, and 50%(w/w) respectively. The four levels compaction were 0, 5, 10 and 15 blows (0, 175, 350, and 404 kPa) proctor hammer blows. Soil properties determined were; soil bulk density and penetration resistance. Hydraulic conductivity was determined without compacting the soil. The result indicated that compaction, organic matter and moisture content as well as their interactions had significant effect (p
