The trend towards less tillage brought about by advances in farm chemicals, especially herbicides, has sharply increased the availability and interest in self-propelled crop sprayers that can be used for both pre- and postplant treatments. This paper accompanies the OwnSprayer computer spreadsheet, which was developed as a decision aid to help individuals think through the self-propelled sprayer ownership decision. Because the purpose of this paper is more of a “user’s guide” as opposed to an academic paper, most of the underlying assumptions and formulas used are simply asserted rather than developed here.
