Abstract: Computer-implemented method for evaluating application threshold values for an application of an agricultural product on an agricultural field, comprising the steps: providing field data comprising geographic data about an agricultural field; segmenting at least a part of the agricultural field in sections and assigning different application threshold values for the agricultural product to different sections; applying the agricultural product on the sections according to the assigned application threshold values for the agricultural product; obtaining evaluation data for the different sections representing the effectiveness of the treatment with the different application threshold values; evaluating the different application threshold values at least based on the evaluation data (e.g. efficacy and or yields).

Abstract: Computer implemented method for providing test design and test instruction data for comparative tests for yield and/or gross margin, efficacy and/or effects on certain vegetation indices on a field for at least a first product and a second product having a similar area of use.

Abstract: Computer implemented method for providing test design and test instruction data for comparative tests for yield and/or gross margin, efficacy and/or effects on certain vegetation indices on a field for one product comprising the following steps: providing field data (S10) comprising at least biomass distribution data and geographic data about the field on which the comparative tests are to be performed; providing test data (S20) comprising at least product use rate data about different constant product use rates of said product, and/or different variable product use rates of said product at a single application time or a sequence of application times of said product whose effect, e.g.
