1. A method for estimating an agricultural management parameter, the method comprising: collecting environmental data associated with at least one field for growing a crop in a particular location, where the collecting is accomplished via a removable weather module on an off-road vehicle in a mobile state while applying an agricultural input, planting, harvesting the crop, or performing another work task and via the removable weather module detached from the vehicle when the vehicle is in a rest state, the removable weather module having one or more sensors and the vehicle associated with a location-determining receiver; compensating for vehicle motion in estimating wind speed data as the collected environmental data in the mobile state; transmitting the collected environmental data to a data processing system; determining whether a sample size of the collected environmental data for a geographic area meets or exceeds a minimum threshold; applying the collected environmental data to an agronomic model for estimating an agricultural management parameter for the geographic area, if the sample size meets or exceeds the minimum threshold, where the agronomic model comprises evapotranspiration for the crop; and making available a prescription for application of an agricultural input to a crop in the particular location consistent with the collected environmental data and the agronomic model.
