Abstract

<p>A seeding system consisting of deep plowing with a chisel plow （deep plowing→soil pulverization→seeding, hereinafter referred to as “chisel deep plowing system”） that can improve soil compaction of the subsoil and poor drainage of the plow layer, both of which are associated with low yield of wheat and soybean, was compared with a conventional seeding system consisting of shallow tillage with a rotary tiller （shallow tillage→seeding） in an upland field converted from paddy field with three-crop rotation of rice, wheat, and soybean in 2 years. The results showed that the chisel deep plowing system reduced soil moisture during seeding-related operations, improved rate of soil pulverization, and increased the porosity, gas phase ratio, available water, and saturated hydraulic conductivity of the subsoil, and these improvements were confirmed until wheat harvest. Furthermore, the improvement of soil physical properties in the subsoil improved drainage of the plow layer during the wheat growing period. In addition, the chisel deep plowing system improved seedling establishment, the number of stems and growth indices at the 4-leaf stage, panicle formation stage, and flag leaf emergence stage. As a result, the chisel deep plowing system increased yield by 12％–13％, mainly by improving the number of panicles. However, in the absence of an underdrain, with poor water permeability of the subsoil, and when heavy rainfall occurs after deep plowing, which may cause delays in seeding-related operations. Therefore, the chisel deep plowing system can be combined with drainage technology, such as underdrain, if necessary for stable introduction into a production site.</p>
