Question 1
Soil is divided into three major soil phases. The three soil phases are; complex, association and undifferentiated groups. Each soil phases has unique chemical and physical properties that learners and surveyors use to distinguish one soil phase from the other. The common physical properties that are used to distinguish the three soil phases are: depth, clay, moist bulk density, available water capacity and organic matter content. On the other had the chemical properties that are used to distinguish the soil phases are cation exchange capacity and pH. The table below shows the chemical and physical properties of the three ...
