General info: A soil pit is a clean hole that is used to see the layers of different types of soil otherwise known as horizons. There are 4 different horizons that we saw in East Woods: the O or A horizon, the E horizon, the B horizon and the C horizon. O horizon is the layer of organic matter that is usually a dark color, there are three layers in the O horizons the first layer you can define the leaves, the second layer you can see the leaves only partially, the last layer you cannot tell a clear distinction of the leaves and other matter. A horizon is a mixture of organic matter and parental material, this layer doesn’t occur very often. E horizon is a gray color because the acids from decomposing organic matter leeched the metals and minerals out into the layers below. B horizon is an orange color that because of all of the minerals that were leeched from the layers above. C horizon is the parental material and is a lighter orange color. We also used the Munsell Soil Color Chart to see what color the soil was exactly and we used the page 10YR because it related to the soils in East Woods.
