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.

An automated implement control system includes one or more distance sensors configured for coupling with an agricultural implement. The one or more distance sensors are configured to measure a ground distance and a canopy distance from the one or more sensors to the ground and crop canopy, respectively. An implement control module is in communication with the one or more distance sensors. The implement control module controls movement of the agricultural implement. The implement control module includes a confidence module configured to determine a ground confidence value based on the measured ground distance and a canopy confidence value based on the measured canopy distance. A target selection module of the implement control module is configured to select one of the measured ground or canopy distances as a control basis for controlling movement of the agricultural implement based on the comparison of confidence values.

A system for an agricultural sprayer includes a boom assembly operably coupled with a chassis. A steering system is operably coupled with the chassis and includes a steering sensor. The system also includes one or more imaging devices and one or more nozzle assemblies. A computing system is operably coupled with the one or more imaging devices and the one or more nozzle assemblies. The computing system is configured to receive data related to a first imaged portion of an agricultural field from the one or more imaging devices; identify a target within the first imaged portion of the agricultural field; receive data related to an inputted steering command from the steering system; and determine a target offset of the target relative to the sprayer path and a boom offset of the assembly relative to the sprayer path.

An apparatus to prevent formation of a vortex has a ring-shaped gasket having a bottom surface and a top surface; and a blade assembly mounted on the top surface and comprising a center portion and plural blades of a defined height. Each of the blades extend from the center portion to the top surface, with each pair of the plural blades defining a filter based at least in part on spacing between the pair of plural blades.

The present disclosure relates to the field of ecological restoration of a coal gangue hill, and in particular, to a solid waste-based porous material, a method for preparing the solid waste-based porous material, and a method of ecological restoration of the coal gangue hill by applying the solid waste-based porous material. A coal-based solid waste restoration material and mycorrhizal solid bacterial agent are mixed to restore the coal gangue hill, the coal-based solid waste restoration material is prepared by mixing coal-based solid waste porous materials, low-rank coal, and waste organic matter and adding a microbial quickly decomposition agent for aerobic fermentation and standing.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.

A ball valve assembly having a valve body with a single inline fluid passage therethrough along a central longitudinal axis. A ball valve is sealingly seated in a valve seat within the valve body. The ball valve includes at least two through-bores, each of the at least two through-bores having a central axis intersecting one another, whereby the ball valve is rotatable between a fully open position and a fully closed position. In one application, the ball valve has two bores intersecting one another such that an angle α between adjacent bore openings of the ball valve are less than 90 degrees and an angle β between other adjacent ends of the ball valve are greater than 90 degrees for applying liquid product in a seed furrow before and after each seed in the furrow but not onto the seed.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements; a fluid pump for pumping liquid manure; a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.
