Abstract: A computer-implemented method for providing variable application rate data for at least two application means of an application system of an application device for applying a treatment product onto an agricultural field, comprising: providing application configuration parameter data for the at least two application means of the application system of the application device; providing position and/or movement data of the application device; providing product application data comprising spatial information about the target application amount for the treatment product to be applied onto the agricultural field; generating a grid of application polygons; and determining variable application rate data for each of the at least two application means of the application system of the application device based on the application configuration parameter data, the position and/or movement data, and the product application data, wherein the variable application rate data is determined for each application polygon in the gene

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.
