Global allocation of arable land between different com- modities Globally, cereal cropping dominates cultivated land Commodities‘ Proportion of land area use (around 50% of total area, Table 1). The remain- (%) ing arable land is used for production of oilseed, fibre, or food and cash crops. In addition, vast areas are Cereals maintained under temporary or permanent pasture for Wheat 16 forage production (2-3 fold greater than the total area Rice 10 under cultivation and permanent crop; Table 1, Fig. Maize 9 1). All cultivated crops, except for legumes (pulses All other cereals 13 and legume oil seeds) require the soil to provide rel- Total 48 atively large amounts of nitrogen (N).

Enhancing legume N2 fixation through plant and soil management,luence legume biomass all have potential to alter net inputs of fixed N. A range of management options can be applied to legumes growing in farming systems to manipulate N. fixation and improve the N benefits to agriculture and agroforestry.

Biological nitrogen fixation: An efficient source of nitrogen for sustainable agricultural productiield potential of food crops and to maximize productivity. Today, the drive for productivity is increasingly combined with a desire for sustainability. For farming systems to remain productive, and to be sustainable in the long-term, it will be necessary to replenish the reserves of nutrients which

Enhancing legume N2 fixation through plant and soil management, of legume N. fixation to the N-economy of any ecosystem is mediated by: (i) legume reliance upon N. fixation for growth, and (ii) the total amount of legume-N accumulated. Strategies that change the numbers of effective rhizobia present in soil, reduce the inhibitory effects of soil nitrate, or inf
