This paper shows the results of analysis of soil compaction influence on wheat yield on headland and inner part of a field, chemical and biological changes in soil. During the 5 years investigation, soil compaction at sowing was 30.56% greater on headland than in the inner part, while during harvest, there was an increase of 37.65% in soil compaction. Large number of passages, which caused intensified soil compaction on headlands, poor conditions for the root system development, and poor microbiological activities led to yield reduction, which was 31.55% in total mass and 26.39% in dry grain mass. Chemical analysis of soil on headland and in the inner part of a field showed higher humus concentration on headlands, due to poor microbiological activities. |
