Boom sprayers are used for spraying pastures of low growing crops to allow downward penetration of droplets for better accessibility to low growing cereals. These spray fertilisers or any liquid through nozzles directed towards the ground. This implement is of great use in low arable fields. Herbicides are also applied through boom sprays. It splits the liquid into small droplets sent into the air. Its nozzles are effective determinants of spraying. The nozzles must be positioned correctly and provided with a continuous supply of the liquid at the right pressure. Successful spraying of fertilisers or pesticides depends on the correct operation and nozzle selection.
