Ontario Soil Above is a soil profile of northern Ontario. As you can see there are leaves and rocks above the soil. As you begin to dig down several feet you dig into roots and small pebbles. When you get to around 3 feet you begin to hit clay mixed with rocks. This can benefit the growing of plants and crops in Ontario. With all the leaves and compost at the top of the soil this can help the plant when it needs the most nutrients. Below is a picture of Ontario farmland. Most of this soil is exactly as the profile with several small changes. A soil profile of the farmland below would have more rocks at the top because it is air gated to let more oxygen into the soil. Another reason for the rocks being pushed to the top is because of the water that melts and is trapped in between spaces and then frozen in the winter. This process pushes all the larger objects to the top of the soil. This is one of Mother Nature’s contributions to agriculture. When all the large rocks are pushed to the top it keeps more space for plants to grow and for more roots to expand and grow. Ontario has many different types of forests. In southern Ontario it is a deciduous forest. There is a large amount of rain and there are long and hot summers, and the winters are relatively mild (supposedly). The soil is very rich in southern Ontario. Mixed forest runs through the center of Ontario. In northern Ontario it is Boreal Forest (coniferous). It is colder in northern Ontario causing the soil to not be as rich as in southern Ontario. In the most northern part of Ontario there is Tundra. The worst soil in Ontario is in the tundra.
