Which farming type involves both crops and animals as a self-sustaining system?

Mixed farming is characterized by the integration of both crops and livestock within the same agricultural system, making it self-sustaining. This farming practice allows farmers to produce food from crops and also raise animals for various purposes, such as meat, milk, and other animal products. The symbiotic relationship between crops and animals enhances sustainability by utilizing manure from livestock as fertilizer for crops, thus improving soil quality and crop yields. Additionally, growing crops can provide feed for the animals, creating a cyclical system where resources are efficiently used and reinforced within the farm. This type of farming supports biodiversity and can be more resilient to market fluctuations compared to systems relying solely on either crops or livestock.

Other farming types mentioned do not incorporate this balanced integration of both crops and livestock in the same manner. Cash cropping focuses primarily on growing crops for sale rather than sustenance, while commercial farming often emphasizes large-scale crop production for profit and may not engage in livestock raising. Posting farming is generally not recognized as a significant farming method in established agricultural practices. Thus, the correct choice emphasizes a holistic approach to agriculture that promotes efficiency, sustainability, and autonomy in food production.
