Phosphorus uptake (weeds and volunteers)

The total amount of phosphorus taken up by weeds and volunteers. Nitrogen content can also be added as a Property to the below ground crop residue Product if the residue amount is known. If phosphorus uptake is added using an array, each value in the array should express the change in uptake, so that by summing the array, the total equals total phosphorus uptake.
