Farms in the Southeast U.S. face low commodity prices along with infertile soils and low water holding capacity. Yields of crops have beeen stagnant for a number of years requiring higher inputs at increasing prices to maintain yields due to poor rotation practices. Research results have shown benefits of bahiagrass or other perennial grasses in rotation with agronomic as well as vegetable crops on pest problems and yield. However, many growers say that they cannot afford to rent land and plant it to perennial grasses when they are set up for row crops (cotton/peanut). Land rent continues to spiral upwards as more pressure is being put on land for uses other than agriculture. This tri-state project using bahiagrass in the system with livestock is based on research done on individual components of the system over the years that have shown reduced pest problems and increased yields as well as many increased soil health components. An economic model was developed for grower use to help them look at the system when trying to decide whether the system would work for their operation. The economics of the perennial grass rotation with livestock is superior to the conventional cotton/peanut rotation. Likewise, environmental aspects including soil nitrates lost to leaching, increased earthworm populations, better water infiltration, etc. are notably better where the deep rooted perennial grasses are in the rotation and is carried over for the next couple of years to the row crops.
