: The use of alfalfa ( lucernă ) and clover in crop rotations to improve soil structure while providing high-protein feed for dairy and beef cattle [3]. 2. Economic Diversification
: Converting grain into milk or meat increases the profit margin per hectare compared to selling raw grain on the market [5]. 3. Sustainability and Soil Health
: If crop yields are low due to weather (e.g., drought), livestock acts as a "buffer" for income [4].
: Mixed systems are shown to increase soil organic matter significantly more than crop-only farms [2, 6].
: Incentives for farmers to maintain "eco-schemes" that involve permanent pastures and animal welfare standards [5].
A central pillar of these studies is the impact on the Romanian "Chernozem" (black soil).
Modern research emphasizes the symbiotic relationship between cattle and field crops. In Romanian agricultural models, this integration focuses on:
