Agrochemical distribution accuracy is critical for an effective intervention with a significant impact both on production costs and on the environment. Here we present the results obtained on processingtomato crops using a sprayer boom with and without nozzle control integrated with an RTK (Real Time Kinematic) automatic guidance system. The trials were carried out on tomato crops cultivated in fields of different shapes in a farm located in the Po’ Valley (Piacenza), using a self-propelled sprayer with a capacity of 1000 L and a 14 m opening boom, with a three-channel direct injection distribution system. The self-propelled sprayer was equipped with an automatic guidance system and integrated nozzle control on each boom section. Several parameters were recorded including the speed (km/h) and treated surface (ha). The analysis of the data collected shows an average overlap reduction of 15% compared to conventional guidance, a value that increases with the irregularity of the field. This technology can improve the environmental sustainability of agrochemical distribution due to the reduction in the consumption of pesticides and can improve the overall welfare of the operator as well.
