Soil Content:
The Serengeti plains have nutrient rich soil made up of volcanic sands. The volcanic ash produces a soil called vertisol which supports many plant colonies. The eruption of the Kermimasi volcano around 150,000 years ago produced this rich soil. The soil is used mainly for the large amounts of grass that the herbivores graze on throughout the years. Fire is a crucial part to this ecosystem's survival, this sustained level of grazing forces the soil composition to be so rich and the nutrients to recycle quickly.
