2009, Agricultural SystemsCitation Excerpt :Cereal yields improve following the use of pastures and break crops in land-use sequences, therefore, these enterprises are tactically grown to sustain profitable production. Soil fertility is considered in RIM through depiction of a percentage increase in crop yield when following a legume and the reduction in nitrogenous fertiliser required in this instance (Pannell and Falconer, 1988). The annual ryegrass population begins from an initial seed population, which by default represents a standard weed burden in the wheatbelt (500 seeds per square metre).
