Title: Innovations by William W. Preheim

Introduction

William W. Preheim is a notable inventor based in Minneapolis, Kansas, who has made significant contributions to agricultural technology. With a total of five patents to his name, he has focused on developing innovative solutions that enhance the efficiency of crop planting and nutrient application.

Latest Patents

One of his latest patents is the "Twin Row Planter," which presents an apparatus and method to precisely meter and dispense two or more crop inputs using a common metering disc. This invention aims to achieve proper placement in the soil relative to one another. In this embodiment, dry granular or granulized fertilizer is metered from one side of the disc while seed is metered from the opposite side. The fertilizer is placed in a concentrated 'pulse' at equal distances between seeds within a common seed furrow or between seed furrows. This design improves nutrient use efficiency by minimizing soil-to-fertilizer contact and subsequent chemical reactions that can render applied nutrients less available to plants. Additionally, pressurized air may assist in the discharge of both seed and fertilizer from the disc meter, ensuring precise spacing in the soil. A cover can also be placed on the meter and metering disc to recirculate air, minimizing potential atmospheric contamination from seed coatings and fertilizer materials.

Another significant patent is the "Dual Product Dispensing Disk for Metering Device," which also focuses on dispensing two or more crop inputs for optimal soil placement. Similar to the Twin Row Planter, this metering disk allows for the metering of dry granular or granulized fertilizer from one side and seed from the opposite side of the same disc. The design aims to enhance nutrient use efficiency and ensure precise spacing in the soil, utilizing pressurized air for discharge and incorporating a cover to reduce contamination risks.
