Abstract: A calibration device that utilises sensor data from an optical sensor to develop one or more calibration parameters for controlling operation of a sprayer utilising itself optical sensors and transmitting the calibration parameters to said sprayer. A method of calibrating a sprayer utilising the calibration information is also disclosed. A method of pasture or crop management for a region of interest in which a composite representation of cumulative substance applications is used to developing a representation in which sub regions of the region of interest having prescribed characteristics are visually differentiated from other regions. The spatial distribution of calibration values may also be recorded and used to analyse substance application against calibration values to develop a report of apparently anomalous calibration values.

Abstract: An apparatus for applying one or more substances to an area of interest, the apparatus having sensors detecting one or more conditions of a sample area proximate the sensor, wherein, the control system is configured to allow for an operator selection between distributing or not distributing a substance or substances via the independently operable outlet(s) controlled by the control system when the control system determines: the sample area proximate at least one sensor or group of sensors is having one or more conditions which meet at least one predetermined condition parameter for that or those condition(s); or the sample area proximate at least one sensor or group of sensors is having one or more conditions which do not meet at least one predetermined condition parameter for that or those condition(s).
