The N leaching for pasture blocks with fodder crops rotating through is split into that which came from the pastoral phase, and is shown under the pastoral block outputs, and that which came from the fodder crop phase, which is shown under the fodder crops outputs.
Total pastoral N loss = pastoral phase N loss x (block area - fodder crop area)
Total fodder crop N loss = fodder crop phase N loss x fodder crop area
It has been done this way to make it easier to see the impact of the fodder crop phase
