Which of the following is a disadvantage of mixed farming?

The correct answer is Option (2) → Aprior knowldge is required about nutrient demand

Mixed farming raises crops and livestock together, and several crops side by side, so the farmer must know in advance the nutrient demand of every component and how they compete for nitrogen, phosphorus and potassium. That need for prior technical knowledge and careful planning is the drawback of the system.

Reduced soil erosion, closed nutrient cycling through the return of farmyard manure, and greater on-farm biodiversity are the well known advantages of mixed farming.
