To take advantage of conservation tillage systems (including direct drilling and non-inversion) in central Iran, it is important to study the effects of different cultivation
Much of the differences in soil compression data are not in good agreement with earlier ®ndings, dis- cussed by Canarache (1980) and in part brie¯y presented here, which had shown
However, this result facilitated mea- surement of the effects of the compaction treatment on crop growth and yield without the complicating effect of different amounts of stored
