Using the spray plan and test speed to check other functions The spray plan identifies what the total flow rate (L/min) through the boom should be at a given speed, application volume (L/ha), nozzle spacing or section width (m) and pressure... Tank size and increments can be checked by using a calibrated in-fill meter or by weighing the contents using a weigh bridge...

The protocol consists of ten sections, intended to provide guidance for the standard measurement, recording and interpretation of soil conductivity data; particularly for third parties that might receive the data for subsequent analyses and development of recommendations... Some contractors provide both data sets at no extra cost... Each person in the soil conductivity mapping services industry shall have full regard for achieving excellence in the practice of the surveying and interpretation and of maintaining the highest standards of ethical conduct in responsibilities and work for an employer, all clients, colleagues and associates and society at large, and shall: 1...

Manage speed to eliminate spray drift.. A Canadian study showed that, during higher wind speeds of about 20 kilometres per hour, machinery travelling at about 30km/h almost doubled the amount of chemical contributing to spray drift risk, compared with machinery travel speeds of 8km/h... Spray operators are advised to avoid travel speeds above 16 to 18km/h during higher wind speeds unless there is excellent boom height control and equipment is set up to minimise airborne droplets by providing spray quality which is coarse or larger...
