Determination of Qualitative Indicators of Work in the Application of Solid Chemical Fertilizers

Abstract

One main means of achieving a constant, reliable and high-value yield is by correctly applying the fertilizers. The correct use of fertilizers implies the scientific basis and the knowledge of all the factors that influence the efficiency of their application. The main aim of the experiment was to study the uniformity of fertilizer application at different travel speeds. In the present study, the machinery used was a Massey Ferguson tractor with a Rauch spreader that was working at the speeds of 6, 11, 17 km/h. The fertilizer was collected and measured with a Kern precision balance. The obtained results show that at the travel speed of 6 km/h, the distributed quantity of fertilizer was between 24.04 g/m2 and 31.81 g/m2 on the membrane verified on 3 different determinations. Using an 11km/h travel speed the results obtained were between 24.14 g/m2 and 26.78 g/m2, by using this results we could determine that this speed was the most appropriate for carrying out the fertilizing process. Lastly, the speed that was used was 17 km/h and the obtained quantity of fertilizer was between 16.85g/m2 and 31.31 g/m2
