Soil compaction as one of the cause of lower tobacco yields in the Republic of Croatia

In Croatia, the production of tobacco is located on sandy and silty soils along valley of river Drava. Both high content of silt particles or fine sand in the mechanical structure of the soil, and the frequent shallow tillage, and really been promoted the extension of soil compaction in the ploughed layer and below that. The subsoil compaction through limiting of the root penetration into the soil has significantly decreased the yield of tobacco in the last decades. In the field trial 3 ploughing variants that are to a depth of 20, 30 and 40 cm were compared. While the former pan compaction has been lasted at two variants however the deep ploughing has successfully reduced the compaction and increased the aeration in the soil. Improvement of the soil physical state has fairly contributed to the deep rooting and by this means producing a higher leaf-yield of tobacco.
