Using the CROPGRO-Perennial Forage Model to simulate the effect of asymbiotic nitrogen fixation on the growth of brachiariagrass

Abstract

There is an increase in global demand to reduce fossil fuel use and to create sustainable intensification of animal production systems. Alternative sources of mineral nitrogen fertilizers have been shown to increase herbage accumulation. The environment in which plants thrive is dynamic and complex due to the nature of the soil-plant-atmosphere interactions. Modeling can evaluate and explain these aspects.
