How would i reword this and also add more?

Chinese agriculture was the most advanced in the world during the 18th century. However, cheap labor in the densely populated Chinese land brought on the need for widespread use of machinery for the countryside. New fruits such as potatoes, peanuts, corn, special maize, and sorghum millet from the Americas helped the Chinese population obtain better, longer-lasting nourishment. In addition, these crops could be used in industrial agriculture, further stimulating private entrepreneurship, general employment, and the agricultural economy. Other crops of great use include: tea, cotton, and sugarcane.
