Title : Soil compaction with wheels of aggregates for fertilization with liquid manure
Key words : soil, soil compaction, fertilization set, agricultural tractor
Summary :

Te objective of the research was determination of the impact of loading capacity of fertilization sets on soil compaction. Degree of soil compaction was determined based on four indexes. Three fertilization sets were selected for research: set A – tractor Renault 95.14 plus a waste removal vehicle of cubic capacity of 6 m3, set B – tractor John Deere 6420 plus a waste removal vehicle 12 m3, and set C Valtra N121 plus a waste removal vehicle 8 m3. Four indexes were determined: field area compaction, loading a field with sets crossings, degree of compaction in the trace of wheels and cubic capacity of ruts. It was determined that the biggest surface of the compacted field was for the set A (27%) and the smallest for the set B (16%). Loading of a field with the sets crossings was the highest also for the set A (212 kN•km•ha-1) and the lowest for the set B (167 kN•km•ha-1). Degree of compaction in the trace of wheels was the highest for the set B (105 kN•m-1) and the lowest for the set A (77 kN•m-1). The highest cubic capacity of ruts was determined on the field fertilized with the set A (99 m3) and the lowest for the set B (61 m3). From among the technical parameters of fertilization machines the following affect the soil compaction degree: tractor mass and a waste removal vehicle mass and its cubic capacity and the working width, which depends on the application unit which was used. The set B may be recognized as the the best selected fertilization set (a tractor and a waste removal vehicle) on account of soil compaction and the least favourable – the set A.
