a)Luvisols
-Occurrence: Makindu-Kibwezi area.
-Luvisols are strongly leached soils having argillic B horizons with a relatively high base status and BSP of more than 50%.
-The high silt content makes luvisols susceptible to structure deterioration and erosion if not well protected.
-In some places, the dense subsoil causes temporarily reducing conditions with a agnostic color pattern.
-Most Luvisols are fertile soils and suitable for a wide range of agricultural uses.
b)Cambisols
-Occurrence in Kenya;Isiolo, Marsabit, parts of Machakos.
-In hilly or mountainous areas, where Cambisols are most frequent, care should be taken to prevent erosion when the surface is bare.
-Cambisols are among the better agricultural soils in Africa as they are less depleted of nutrients than other tropical soils.
-Have a sufficiently high nutrient-holding capacity to retain fertilisers
-In such conditions, these soils are best be kept under forest or perennial crops such as tea.
-Weaknesses;Strongly weathered Cambisols contain limited amounts of nutrients.
-Opportunities;Depending on their depth, their water-holding capacity can be high.
