Soil
The soil of the temperate grassland is deep and dark. The upper layers are the most rich because of the buildup of many layers of dead branches, stems and roots. These dead roots provide a great amount of nutrition for the plants. That's why there are so many different types of grasses growing there. The Farmers have also cultivated fields of crops because of the rich soil. That isn't good because eventually the temperate grasslands are going to decrease in size.
