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 base, at least one flexible or pivoting application member connected to the base and disposed to apply fluid to the plants, and a stabilizer associated with the at least one flexible or pivoting application member. The stabilizer can reduce movement of the application member to provide a more consistent fluid application to the plants.

A liquid dispensing apparatus for applying liquid products to row crops. The liquid dispensing apparatus includes a plurality of drop assemblies supported by and laterally spaced along a boom structure. Each of the drop assemblies includes dribble hoses for dribbling a liquid product onto the soil in a rhizosphere of adjacent crop rows. The drop assemblies may include a spray assembly for spraying the row crops. The dribble hoses may be supported by a base unit with positionable support brackets

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.

A spray boom for spraying a fluid on a target includes a boom frame and a spray section coupled to the boom frame. The spray section includes a spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe and configured to be fluidly coupled to the fluid source. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator is controllably extending and retracting to move the spray pipe and nozzle between a raised position and a lowered position. A trip assembly is coupled between the boom frame and actuator for biasing the spray section to a biased position in which the actuator and nozzle are substantially perpendicular to the underlying surface.

A spray boom includes a body having a length defined between a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. An internal cavity is defined in the body internally of the inner surface. A light-emitting system is integrally formed in the body in an outer layer thereof or at a location between the inner surface and the outer surface. The light-emitting system has an on state and an off state in which it is adapted to emit a light when in the on state.

Described herein are implements and application units having a trench closer for closing a trench during applications with respect to agricultural plants of agricultural fields. In one embodiment, a trench closer for a fertilizer applicator includes a bar moved through a field transverse to a direction of travel, a fertilizer applicator connected to the bar for forming a trench in soil. The fertilizer applicator comprises a coulter, a knife, or a coulter and a knife, and a trench closer disposed behind the fertilizer applicator in the direction of travel and connected to the fertilizer applicator or the bar.

Embodiments include individual physical spray nozzles that have passageways inside to combine fluids that flow out of the spray nozzles. The nozzles have at least two valves that are opened and closed in an interleaved manner. The nozzles have multiple outlets. Such nozzles are mounted on a variety of implements including agricultural or industrial spray booms.

A system for growing plants, the system may include a substrate having one or more weakened areas or openings: one or more grow portions coupled to the substrate and situated at the one or more weakened areas or openings and having at least one seed or plant; and/or a fluid distribution portion coupled to the substrate and configured to provide fluid to the one or more grow portions. The system may further include a method of operation including one or more acts of: obtaining a weather forecast for a future time period; determining whether rain is expected during the future time period; and preventing, terminating, or restricting an irrigation cycle when it is determined that rain is expected during the future time period. The restricting may restrict a flow of liquid during the irrigation cycle or shorten the irrigation interval.
