Economic Feasibility of Crop‐Livestock Integration System in Brazil

Agribusiness, EarlyView.
ABSTRACT We investigate the economic feasibility of the Brazilian crop‐livestock integration system. Under this system, the Brazilian farmer can produce soybeans, corn, and graze for cattle on the same land during one crop year. This technology can substantially increase agricultural production in the country.
