  stribution of the different types of fertilizers is essential. In my study, I recommend a solution for the mechanization of fertilizer distribution on probe parcels. I have designed and constructed a new plot fertilizer distributor. This machine of moderate price can be controlled easily; it provides accurate distribution and versatility. In my paper I give an outline of its basic principles of operation.
  The spreading pattern of the complete plot fertilizer distributor was investigated on the top of a test-desk. I constructed a test-desk, which has 16 collecting trays in transversal direction and 1o collecting trays in longitudinal direction. I developed a new method for data interpretation. A map of distribution was designed to process the data of the measured 16o trays. In the distributor, a map precisely traced the pattern of granule distribution and the amount of fertilizer as well. After this, I defined the transversal and longitudinal coefficient of variations for spreading. On the basis of my investigations I can conclude that the plot fertilizer distributor has excellent, even spreading (longitudinal and transversal) patterns.

  Efficient plant production requires modern production technologies, including a nutrient supply of a scientific basis. The harmonic nutrient supply of quality products that are required by market demands can be produced by the optimal combination of a compound system of requirements. These requirements are partly preparatory (soil investigations, yield measurements, preparation of digital field maps) and are partly based on the knowledge of the most significant characteristics of the applied nutrients. Most artificial fertilizers are applied by spinning disc fertilizer spreaders all over the world, therefore, it is advisable to use them in Hungary as well. Importantly, these machines should be well adjustable, capable of the exact measurement and control of the spread quantity, as well as of even spreading. My report has investigated only the most significant technical requirements affecting the even application of nutrients.

  The mechanization of fertilizer distribution in the case of different types of fertilizers often poses problems. As a result, I have designed and constructed a brand new type of plot fertilizer distributor. This machine of moderate price can be controlled easily; it provides accurate distribution and versatility. The main part of this machine is an ambilateral cogged belt. I briefly present the operation and the advantages of cogged belts.
  I investigated the spreading patterns at the front and the end part of the experimental plot. I demonstrate a method never seen so far in the investigation of spreading patterns. My method also shows marginal divergences and flat wedge effects in spreading patterns.
