When a farmer engages in both plant and animal husbandry, they are practicing mixed farming.
Mixed farming involves raising both crops and animals on the same farm. This type of farming is beneficial for several reasons. Firstly, animal waste can be used as fertilizer for crops, reducing the need for chemical fertilizers. Secondly, crops can be used to feed the animals, reducing the need for expensive animal feed. Thirdly, animals can provide an additional source of income for the farmer through the sale of meat, dairy products, and other animal products.
In contrast, crop rotation involves planting different crops in the same field in different seasons to maintain soil fertility, prevent pests and diseases, and improve crop yields. Mixed cropping involves planting two or more crops in the same field at the same time to increase productivity and reduce risks associated with mono-cropping. Lay farming, on the other hand, refers to farming on land that has not been previously farmed.
Therefore, the correct term for a farmer who engages in both plant and animal husbandry is mixed farming.
