oil Microbial Activity Under Complementary Applications of Organic and Inorganic Amendments

The research described and quantified soil consistency as cumulative consistency value (CCV) at two moisture levels for different horizons of soil profiles located on sedimentary and basement complex parent materials. It was found that the CCVs of soils formed on sedimentary deposits were between 18 and 28 while the CCVs for the soils formed on the basement complex were between 0 and 27. No significant difference was observed between the CCVs of sedimentary deposits’ and basement complex soils. Correlating CCVs with clay and organic matter contents, no significant positive and negative relationships were observed with r = 0.20 and -0.28 respectively. It is pertinent to always determine soil consistency and expressed as CCV because it can be utilized in inferring the level of soil compaction and deciding on the best management practice which could include organic matter addition as well as in making choice of instruments for soil manipulation.
