Abstract:

Seedling emergence of maize is strongly affected by soil compaction. It is strongly decreased with increasing bulk density, soil suction, and decreasing oxygen diffusion rates. The critical values for these soil physical parameters were 1.49/cm3, 3 atm, and 40 x 10-8 g O2/cm2/min. Seed placement depth was critical at 4 cm.
