Field structures refer to the various physical arrangements and systems used in agricultural fields to optimize crop production. These structures can include elements like irrigation systems, fences, and drainage ditches, which help manage water, protect crops, and improve soil health. Additionally, field structures can involve the layout of planting rows and the use of crop rotation techniques. By organizing fields effectively, farmers can enhance productivity, reduce soil erosion, and promote sustainable farming practices. Understanding these structures is essential for efficient land management and maximizing agricultural yields.
