摘要:
Aspects of the present invention involve an extension adapted to extend from a planter, such as the seed tube portion of the planter, into a seed furrow in order to engage seeds being deposited therein, where such engagement may involve deflecting the seeds toward the vertex region of the furrow and/or firming the seeds in the furrow. The extension includes or supports a fluid distribution arrangement such as a hose or the like, which may be separate or integral with the liquid supply hose of a planter. The fluid distribution arrangement is adapted to supply fluid, such as liquid fertilizer, insecticide, water, etc., to the furrow. A valve is provided in the fluid flow path in the region of the fluid distribution arrangement to control the distribution of fluid to the furrow. The valve may be a check valve that allows fluid flow therethrough when fluid pressure exceeds a value such that the valve opens, and prevents fluid flow when the pressure decreases below the valve activation pressure.
