Nitrogen uptake (above and below ground crop residue)

The total amount of nitrogen taken up in the above and below ground crop residue. Nitrogen content can also be added as a Property to the above and below ground crop residue Products if the residue amount is known. If nitrogen 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 nitrogen uptake.

Also known as: N uptake; N uptake crop residue
