520			_aPotential mechanisms for interactions to occur between mineral and organic sources of nutrients are discussed. The most important mechanisms for interactions are considered to be effects of available C on the mineralization or immobilization of N, effects of available C on the availability of P, and effects of P on the capture of mineral N in soil due to increased crop root growth or due to increased N2-fixation in legumes. The major benefits of using different types of resources are considered to derive from their additive strength (i.e. addition of larger amounts of nutrients) rather than from any true 'interaction', particularly in soils which are not particularly responsive to P.
