A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

A hydraulic spray nozzle for an agricultural implement includes at least one of a bleed valve and an annular valve. The bleed valve is configured to control flow of a bleed portion of the liquid provided to the nozzle for spraying. The bleed portion can be routed back to a supply tank for later use. The bleed valve can be an annular valve. A spray valve within the nozzle can also be an annular valve.

A system for irrigating an agricultural field includes a high-clearance vehicle (e.g., a sprayer vehicle) and a hose configured to connect an external water source to the high-clearance vehicle while the high-clearance vehicle traverses the agricultural field. A method for irrigating an agricultural field includes connecting an external water source to a high-clearance vehicle by a hose, and dispensing water from the nozzles of the high-clearance vehicle while the external water source remains connected thereto and while the high-clearance vehicle traverses the agricultural field.

The present invention relates to methods and vehicles for separately applying a solid fertilizer and a liquid fertilizer additive to a working area of a field.

An anhydrous ammonia trailer including first and second longitudinally extending frame members having first and second cross-members selectively removably secured to the frame member with the cross-members being longitudinally adjustably secured to the frame member. The cross-members enable the trailer to have first and second ammonia tanks mounted on the trailer. The trailer also enables a single ammonia tank to be supported on the adjustable cross-members.

Various embodiments of a system for automatically sensing and spraying plants and/or plant precursors as they are planted or otherwise distributed on and/or within the ground is disclosed.

A control system for a suspended boom sprayer of a vehicle comprises: first and second sensors each configured to be disposed on respective first and second boom wings of the suspended boom sprayer and to provide an output responsive to a rotation of the first and second wings caused by a disturbance torque; a processor, configured to determine a differential acceleration between the first and second wings based on the outputs of the respective sensors, and to determine the disturbance torque corresponding to the differential acceleration; and at least one actuator, controllable to move one or both of the first and second wings in order to counter the disturbance torque.

There is disclosed a dry fertilizer comprising citric acid and potassium carbonate or potassium bicarbonate. The dry fertilizer may be one of a tablet, powder, meal and pellet. The dry fertilizer may include one of plant nutrients, soil nutrients, carbonates, bicarbonates, acids, oils, microorganisms, biostimulants, enzymes, hormones, fertilizers, lubricants, and binding agents. The dry fertilizer may be packaged.

A set for assembling a length and shape adjustable planter comprising (a) a plurality of elongate troughs being length customizable by cutting thereof; the elongate troughs having a longitudinal axis and a H-inverted cross section; the elongate troughs interconnectable therebetween; (b) interconnecting members configured for interconnecting the elongate troughs in series; and (c) end members configured for mounting onto a free end of the elongate troughs. A surface of each trough at least partially is provided with a surface profile distributed over a length of the trough. The interconnecting members are securable on the surface profile.
