GEOECOLOGY Describe and explain the characteristics of any one soil type you have studied. (2009 Q18‚ 80 marks) In this answer I will discuss the characteristics of the Brown Earth soil. Brown Earth soils are known as a zonal soil as they developed as a result of the Cool Temperate Oceanic climate and the natural‚ mixed‚ deciduous vegetation of this climatic region. This climatic region is located between 30o and 55o North of the Equator. Brown Earths are the most common soil type
