This calculator gives a rough guide based on the inputs entered. It will give an idea of returns you may expect from installing Precision VRI on your irrigator, but does not take costs or variables that may occur as a result of the increased production into account. The accuracy or completeness of these calculations is not guaranteed nor is its applicability to differing individual farm circumstances. The calculator has been created using assumptions based on New Zealand farming conditions, caution should be applied if using the calculator in other countries. We reserve the right to alter this calculator and its algorithms at any time without notice.
