The correct answer is D. All of the above.
Integrated farming is a system of crop and livestock production that uses natural processes to recycle nutrients and create a more sustainable system. It involves combining crop cultivation and livestock rearing, utilizing livestock waste for manure, and diversifying income sources for farmers.
By combining crop cultivation and livestock rearing, farmers can create a more efficient system that uses resources more effectively. Crops can be used to feed livestock, and livestock waste can be used to fertilize crops. This helps to reduce the need for external inputs, such as fertilizer and pesticides.
Utilizing livestock waste for manure is a sustainable way to recycle nutrients and improve soil health. Manure contains essential nutrients that can help to improve crop yields. It also helps to improve soil structure and water retention.
Diversifying income sources is important for farmers to reduce their risk and increase their profits. Integrated farming can help farmers to diversify their income by producing a variety of crops and livestock. This can help to protect farmers from fluctuations in the market price of individual products.
Integrated farming is a sustainable and efficient way to produce food. It can help to reduce the environmental impact of agriculture and improve the livelihoods of farmers.
