Which farming approach incorporates both crop cultivation and animal husbandry?

Mixed farming is the correct answer because it specifically refers to an agricultural system that combines both the cultivation of crops and the rearing of animals. This integrated approach allows farmers to benefit from the advantages of both crop production and livestock management. For instance, the crops can be used as feed for the animals, while the animals contribute manure that enriches the soil, thus promoting sustainable practices and optimizing productivity.

In contrast, posting farming does not specifically refer to a recognized agricultural practice; it might suggest an unrelated concept. Cash cropping focuses solely on producing crops for sale rather than personal consumption or animal feed, which limits the inclusion of livestock. Cultivation farming is a broader term that generally refers to the act of growing crops but does not necessarily imply the incorporation of animal husbandry. This distinction makes mixed farming the ideal choice, as it explicitly encompasses both practices, leading to a more holistic and sustainable farming approach.
