Methods of Cropping and Popular Crops in the U.S.

Cropping is not simply planting and letting it grow, there are various methods of cropping that are used in the agricultural industry. Such as mono cropping, crop rotation, sequential cropping, and mixed intercropping. Each method of cropping have their purposes and possibly disadvantages to them as well. Himanshu Arora defines mono cropping as where a field only grows one specific crop year round. Mono Cropping has its disadvantages, according to Himanshu Arora, such as the risk of the soil losing its fertility. Following mono cropping, another method of cropping is relay cropping. According to the National Library of Medicine, Relay cropping may solve a number of conflicts such as inefficient use of available resources, controversies in sowing time, fertilizer application, and soil degradation. The result coming from the use of relay cropping is higher crop output. In the United States, corn is the largest crop produced, and soybean follows in at second, according to the government of Alberta. Referring to a map given by the Government of Alberta, the most popular region to grow these popular crops are in the inner states of the U.S., it is where the crops are most successful in output.
