The United States is the world's largest producer of corn and soybeans, accounting for nearly 40% of global production. These two crops are vital to the country's economy and food supply. Corn and soybeans are warm-season crops that thrive in warm temperatures and long daylight hours. In the United States, the best time for cultivation is spring and summer. Typically, corn is planted in the Midwest between late April and early May, while soybeans are planted from mid-May to early July.
