The performance of spraying machines in the improvement of rangelands

Plants during their growth, they are affected by enemies and diseases or they have to compete various weeds. Consequently, for their protection is essential to control all these enemies. The control can be accomplished with chemical compounds and their application is achieved with sprayings. Mechanical spraying in rangelands can be applied with a lot of methods. There are a lot of application methods for mechanical spraying in rangelands, provided that the methods and the machine used are the proper one to achieve our goal (reinforcement of plants, weed control, speed and economy of spraying). The hydraulic pressure sprayer is a machine with sufficient performance for application in rangelands and is carried out in the hydraulic suspension system of a tractor. The sprayer performance which is the total flow of each nozzle and it depends from the quantity of the liquid to spray, from tractor movement speed and spraying width. In this paper, we studied the theoretical performance of the carried hydraulic pressure spraying machine, in works for rangeland improvement, with the aim to extract conclusions for the proper application of sprayers in a way to have a great work performance in short time period with the least possible cost.
