Abstract

A method and apparatus for minimizing the volume of a liquid carrier used for delivering an agricultural product into a furrow during planting. The apparatus includes a seed tube assembly for dispensing seed. A seed firmer assembly is operatively connected to the seed tube assembly. A seed firmer application tube assembly is mounted to the seed firmer assembly. The seed firmer application tube assembly has an outlet end for dispensing a carrier containing an agricultural product. A seed firmer brush is mounted to the outlet end of the seed firmer application tube assembly. The seed firmer brush is configured to contact the carrier containing the agricultural product during the dispensing thereof and brushing the carrier containing the agricultural product onto the seed being dispensed from the seed tube assembly.

Claims

1. An apparatus for minimizing the volume of a liquid carrier used for delivering an agricultural product into a furrow during planting, comprising:

a) a seed tube assembly for dispensing seed;

b) a seed firmer assembly operatively connected to said seed tube assembly;

c) a seed firmer application tube assembly mounted to said seed firmer assembly, said seed firmer application tube assembly having an outlet end for dispensing a carrier containing an agricultural product; and

,

d) a seed firmer brush mounted to the outlet end of the seed firmer application tube assembly, said seed firmer brush configured to contact the carrier containing the agricultural product during the dispensing thereof and brushing the carrier containing the agricultural product onto the seed being dispensed from the seed tube assembly.

2. The apparatus of claim 1 further comprising additional seed firmer application tubes and associated seed firmer brushes mounted thereon.

3. The apparatus of claim 1 further comprising additional seed firmer application tubes and associated seed firmer brushes mounted thereon, wherein each seed firmer application tube provides a different agricultural product.

4. The apparatus of claim 1 further comprising additional seed firmer application tubes and associated seed firmer brushes mounted thereon, wherein each seed firmer application tube provides a different agricultural product, the agricultural products being incompatible.

5. The apparatus of claim 1 further comprising additional seed firmer application tubes and associated seed firmer brushes mounted thereon, wherein each seed firmer application tube provides a different agricultural product, the agricultural products being incompatible, a first agricultural product being a biological and a second agricultural product being a chemical.

6. The apparatus of claim 1 wherein said seed firmer brush is mounted to said seed firmer application tube assembly by a clamp.

7. The apparatus of claim 1 further comprising at least one additional seed firmer application tube and associated seed firmer brush mounted thereon, wherein said additional seed firmer application tube is mounted within the seed firmer assembly.
