It is very important to adjust the seeding rate for PLS for each new seed lot that is used, since PLS varies from one seed lot to another. It is highly adaptable to a wide range of soils and growing conditions. Carbon sequestration by switchgrass, a C4 plant with high cellulosic conversion rates and drought tolerance, facilitates its use as a biofuel directly or by ethanolic conversion, making it a valuable, natural renewable energy resource . When planting for wildlife, reduce the seeding rate by 50-60% (i.e., 2 - 3 lbs PLS per acre). When planting for wildlife, reduce the seeding rate by 50-60% (i.e., 2 - 3 lbs PLS per acre).
