dc.description.abstract <p>Challenges to sustainable agriculture include optimizing nitrogen (N) availability, maintaining profitability by reducing input costs, such as synthetic N fertilizers, and minimizing the loss of nitrate-N. Production of a legume green manure in a crop sequence is a typical method used to reduce or eliminate the need for applying synthetic N fertilizer to succeeding crops. Legumes or legume/small grain mixtures are often used as green manures because of the symbiotic association of most legume species with N fixing <em>Rhizobium</em> bacteria. The dynamics of nitrogen (N) mineralization in the soil after legume incorporation are complex. To contribute adequate amounts of plant-available N to the subsequent crop, the incorporated green manures must decompose sufficiently and in synchrony with the N demand of crops such as corn.</p>
