Abstract
A shank for use in a hoe-type drill designed primarily for minimum till or no-till farm operations has a sealing arrangement for permitting the application of anhydrous gas or other gaseous fertilizers in a deep application, and, at the same time, seeding and applying longer lasting fertilizer, such as granular or liquid fertilizers at different depths. The problems with applying gaseous type fertilizers at the same time other operations are occurring have been substantial because of unwanted escape of the gas prior to the closing of the furrow in a multiple operation; freezing up of the seed and granular fertilizer outlets as the gas evaporates; as well as permitting dry top soil to fall into the furrow to result in a dry seed bed, particularly in semi-arid farming regions where no-till farming is carried out. The present device provides for a multi-level sealing arrangement that insures adequately sealing of the gaseous fertilizer; proper furrow formation for receiving of other types of fertilizer and/or seed; and also forming the seed bed to minimize the dry soil that contacts the seed.
