Method for spreading spraying liquid onto arable agricultural land

Abstract

A method for spreading a spraying liquid onto arable agricultural land by way of several switching elements arranged on an agricultural sprayer and controllable in an open-loop and/or closed-loop manner and in the manner of a pulse width modulation, where the spraying liquid is spread as required onto the arable agricultural land; where a first opening duration associated with a first switching element and at least one further opening duration associated with a further switching element is determined; where spreading the spraying liquid is influenced at least in part by way of the respective opening duration; where at least one upper and/or lower limit opening duration associated with the switching elements is used; and where the first and further determined opening duration is compared with the upper and/or lower limit opening duration. In order to further improve in a simple manner, the spreading process of the spraying liquid, in particular to improve the achievable spreading precision and/or spreading quality, it is provided in the event of the upper limit opening duration being exceeded and/or the lower limit opening duration being undercut by one of the determined opening durations, that the first and further opening durations are accordingly jointly corrected.
