The correct answer is D. Piedmont soil is mostly found in the Piedmont region of the United States, which is located in the eastern part of the country. It is a type of soil that is formed from the weathering of the Appalachian Mountains. Piedmont soil is rich in organic matter and has a high clay content. It is good for growing a variety of crops, including corn, soybeans, and tobacco.
Option A is true because Piedmont soil is rich in organic matter. Organic matter is a type of soil that is made up of the remains of plants and animals. It helps to improve the soil’s structure and fertility.
Option B is true because Piedmont soil has a high clay content. Clay is a type of soil that is made up of very small particles. It helps to hold water and nutrients in the soil.
Option C is false because Piedmont soil is not good for rice crops. Rice crops need a lot of water, and Piedmont soil is not able to hold enough water to support rice crops.
