Perennial grasses offer potential for high lignocellulosic biomass yields on marginal land that can be used for conversion to biofuels. However, fertilizer nutrient inputs are often required to maintain high yields. This study evaluated biochar and fermentation residuals as alternative supplemental nutrient sources for elephantgrass (Pennisetum purpureum (L.) Schum.) feedstock production. Treatments were (1) 50 kg N ha−1 (E50); (2) 50 kg N ha−1 + fermentation residual (E50FR); (3) 50 kg N ha−1… CONTINUE READING
