In response to questions being asked by tobacco growers about the effectiveness of sulfate of potash magnesia (SPM; 21% K2O and 11% Mg) as coinpared to sulfate of potash (SP; 50% K2O), field studies were conducted during 1993-1994 to compare the two potassium (K) sources for use on burley tobacco. Any effect of SPM on yield of tobacco should be due to Mg since the only difference between the two sources in kind of nutrient contained is the presence of magnesium (Mg) in SPM. To compare the two K sources, we selected field sites low enough …

Compaction of tobacco fields caused by overworking or working soils when they are too wet has become a topic of concern to burley producers in recent years. Despite the viewpoint of some producers that annual subsoiling of tobacco fields is a profitable practice, particularly on soils which percolate water slowly, the University of Kentucky College of Agriculture recommends subsoiling only for a defined compaction problem. In such cases, some field studies have shown increased yields of burley to tillage practices that penetrate and shatter the compacted layer. Questions persist, however, about the effectiveness of single shank subsoilers used annually by …
