| In order to compare conservation tillage treatments on physical properties of soil, a randomized complete block design (RCBD) with three replications was conducted in the fild of Agricultural Research ,Education and Extension Center of Markazi Province if Iran, during the 2 cropping seasons (2012 and 2013). The treatments were: 1) Moldboard plow + disc (conventional method), 2) Chisel packer, 3) Combined Tillage Tools, and 4) Direct seeding. In both cropping seasons, the tillage operations were carried out based on the experimental treatments in a plot containing fodder corn plant residues (var. SC-704). The physical properties of soil included soil bulk density, soil permeability (infiltration), mean weight diameter (MWD) of aggregates, and soil... |
