Quality Assessment Of Selected Tillage Machines For Secondary Soil Tillage

The aim of this paper is evaluate the quality of soil tillage with combinator for secondary soil tillage. Measurements of tillage quality parameters were performed on August 2017 in Nesperska Lhota near Benesov (Central Bohemia Region) on sandy-loam soil at an altitude of 390 m. This evaluation was carry out on three-row (working tools) pre-seed combinator for soil bed preparing. Quality of soil tillage was assessed after crossing machine. The evaluated parameters of the quality of work are surface covering by crop residues, size of soil aggregates, surface profile and surface roughness. After secondary tillage was observed small number of clods, low surface roughness and an appropriate spreading crop residues. The results demonstrate the effectiveness of the combinator to create a quality pre-seed bed.
