A method of contracting for the sale of a yield-increase and/or crop protection related products includes the steps of mapping, using geo-referencing technology, areas of a field which have been treated with the yield-increase and/or crop protection related product and areas of the field which have not been treated, measuring, using geo-referencing technology, an amount of harvested crop from the field in both the treated and untreated areas, comparing the amount of harvested crop in the treated areas with the amount of harvested crop in the untreated areas to determine a yield increase associated with the treated areas, and charging for application of the yield-increase and/or crop protection related product based on the determined amount of yield increase. The data acquired may be stored in a database for further use and comparison. |
