Abstract

Implements and applicators provide for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a base disposed between adjacent rows of plants, and at least one application member connected to the base and disposed to apply fluid to a rhizosphere of a row of the plants.

First claim

What is claimed is:

1. A fluid applicator, comprising:
a base disposed between plants in adjacent rows;
at least one application member connected to the base; and
a nozzle housing that includes a nozzle and a fluid outlet disposed in the nozzle, wherein the nozzle housing is disposed at an end of the application member to dispense fluid from the application member to the rhizosphere of the plants;
wherein the rhizosphere is a base region of the plants where the plants emerge from the soil, wherein the application member is biased with one of a fluid system, a pneumatic system, or a hydraulic system laterally outward from the base to rotate from a first inner position in a middle of a row between plants in adjacent rows for no fluid application to a second laterally outward position to apply fluid to the rhizosphere of a row of plants.

2. The fluid applicator of claim 1 , wherein the at least one application member comprises a first application member with a first nozzle and a second application member with a second nozzle to apply fluid to the rhizosphere a target region of the plants including a root ball, crown, crown root or mesocotyl.

3. The fluid applicator of claim 1 , wherein the nozzle housing further comprises a wire extending from the nozzle housing and disposed to contact one or more plants of the row of plants.

4. The fluid applicator of claim 1 , wherein the nozzle housing further comprises a ski disposed under the nozzle housing for engaging a ground surface to keep the fluid outlet of the nozzle from contacting the ground surface.

5. The fluid applicator of claim 1 , wherein the nozzle is configured to dispense pressurized fluid from the fluid outlet to the rhizosphere of the plants.
