Impact of crop rotation, fertilizer treatments, and herbicidal applications on the long term maintenance of soil fertilityVI. Examination of progressive differences regarding chemical and physical factors of the yield potential of a soil conducted over the period 1973 through to 1983 In order to investigate the influence of different crop management practices such as crop rotation, fertilizer treatments, and herbicide applications on the yield potential of a soil, the Crop Science Department of the Swiss Federal Institute of Technology (ETH Zürich) conducted a long term field experiment commencing 1973. The experimental location was at the Swiss Federal Research Station for Farm Management and Agricultural Engineering at Tänikon/TG (northeastern Switzerland). Over ten years of research it was found that chemical and physical soil properties had, in general, been only marginally affected by the different experimental treatments. However, consistent studies have shown that certain trends regarding specific factors of greater importance have emerged, which were not observed during the first five year period. Should they persist, the yield potential of the soil could be substantially affected in the long run. Soil reaction, organic carbon content, cation exchange capacity, and aggregate stability have proven to be relatively stable values. Changes of greater significance were evidenced regarding the character of the air‐water regime, a factor of particular importance for this site. Obviously, crop rotation had a marked impact on soil compaction. Therefore under local research conditions, the yield potential of the soil will, in the short term, be most likely endangered by structural soil changes.
