## Abstract

A manure/fertilizer injection applicator provides subsurface manure/fertilizer injection, even at low gallon per acre rates. The applicator of the present invention is a minimal till applicator that causes minimal soil disturbance compared to a conventional plow and, since the application is subsurface, there is no chance of run-off or evaporation of valuable nutrients. The applicator includes a mount to attach multiple applicators to an implement bar and a coulter till wheel to open a small ditch in the soil, an injection tube behind the till wheel for depositing manure or fertilizer, and at least one closer wheel to cover up the small ditch and to bury the manure or fertilizer.

## Claims

### Claim 1

An injection applicator for applying a subsurface product, comprising:
a mounting plate operable to attach to an implement bar of a tractor;
a main arm extending at an angle from the mounting plate, the main arm resiliently resisting movement upward, away from soil, when in use;
a till wheel attached to the main arm;
a secondary arm extending from the main arm;
an injector tube supported by the secondary arm, the injector tube having an opening disposed behind the till wheel, wherein product delivered through the injector tube and out of the opening can be disposed in a ditch formed by pulling the till wheel over the soil; and
at least one closer wheel disposed behind the injector tube, the closer wheel operable to cover the product in the ditch when in use.

### Claim 2 (depends on 1)

The injection applicator of claim 1, wherein a spring assembly provides resistance against the main arm moving upward.

### Claim 3 (depends on 2)

The injection applicator of claim 2, wherein the spring assembly includes an inner spring and an outer spring disposed on the mounting plate.

### Claim 4 (depends on 1)

The injection applicator of claim 1, further comprising one or more mounting brackets operable to secure the mounting plate to the implement bar.

### Claim 5 (depends on 1)

The injection applicator of claim 1, further comprising a closer arm pivotably attached to the secondary arm, the at least one closer wheel attached to the closer arm.

### Claim 6 (depends on 5)

The injection applicator of claim 5, further comprising a closer bracket attaching the closer wheel to the closer arm.

### Claim 7 (depends on 1)

The injection applicator of claim 1, wherein the till wheel is a coulter blade.

### Claim 8 (depends on 1)

The injection applicator of claim 1, wherein the product is selected from a fertilizer and manure.

### Claim 9

An injection applicator for applying a subsurface product, comprising:
a mounting plate;
one or more mounting brackets operable to secure the mounting plate to an implement bar of a tractor;
a main arm extending at an angle from the mounting plate;
a spring assembly operable to resiliently resist movement of the main arm upward, away from soil, when in use;
a till wheel attached to the main arm;
a secondary arm extending from the main arm;
an injector tube supported by the secondary arm, the injector tube having an opening disposed behind the till wheel, wherein product delivered through the injector tube and out of the opening can be disposed in a ditch formed by pulling the till wheel over the soil;
a closer arm pivotably attached to the secondary arm; and
at least one closer wheel disposed behind the injector tube, attached to closer arm, the closer wheel operable to cover the product in the ditch when in use.

### Claim 10 (depends on 9)

The injection applicator of claim 9, wherein the spring assembly includes an inner spring and an outer spring disposed on the mounting plate.

### Claim 11 (depends on 9)

The injection applicator of claim 9, further comprising a closer bracket attaching the closer wheel to the closer arm.
