Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator includes at least one applicator arm, a first nozzle disposed to apply fluid to a rhizosphere of the plants, and a second nozzle disposed to apply fluid between the row of plants.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluid to plants in rows in a field includes a frame, at least one applicator arm disposed in a rhizosphere of plants during fluid flow through the applicator, and a fluid conduit connected to the frame and disposed in the row between plants to deliver fluid to the row between plants.

Described herein are implements and applicators 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 frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

A vehicle has a vehicle frame having a first end and a second end and a first siderail and a second siderail spaced laterally and each extend longitudinally from the first end to the second end. A caster wheel having a lateral axis is rotatably coupled to the vehicle frame towards the first end. Drive wheels defining an axis are rotatably coupled to the vehicle frame towards the second end. A prime mover coupled to the vehicle frame has a base and a vertical driveshaft, which is in operative communication with the drive wheels, extending from the base. The vertical driveshaft has a driveshaft axis closer to the second siderail than the first siderail laterally and closer to the caster wheel axis than the drive wheel axis longitudinally. The base is positioned vertically below most of the length of each of the first siderail and the second siderail.

A product applicator system for dispensing various products onto a ground surface is provided. The system provides an assembly of a protective tube and applicator that protects the product as it travels from the boom to the ground surface. The assembly may include a swivel connection facilitating a rotational movement of the hose assembly to the supporting boom. The protective tube assembly is designed with bending properties that enable the applicator to self-center itself during use.

An automated steering system for an agricultural vehicle operating in a row crop field. The automated steering system includes a correction system having a controller and an alignment sensor. The alignment sensor is disposed between two adjacently spaced crop rows and generates output signals indicative of the alignment sensor's lateral position relative to the two adjacently spaced crop rows as the vehicle advances in the forward direction of travel. The controller receives the generated output signals from the alignment sensor and determines an offset distance of said alignment sensor from a centerline between the two adjacently spaced crop rows. The controller outputs a modified vehicle position signal corresponding to the latitude and longitude position received from said GPS receiver shifted by the offset distance. The vehicle's on board navigation controller causes the vehicles on-board steering control system to steer the vehicle based on the modified vehicle position signal.
