Seed sensors for determining seed placement in a furrow to then target at least one of fluid and solid application with respect to the seed are described herein. Plant sensors for determining location of plants within a field and then targeting at least one of fluid and solid application with respect to the plant are also described herein.

An agricultural implement for applying fertilizer beneath the surface of the soil. The implement has a main frame for connecting the agricultural implement to agricultural equipment. A swing arm is pivotally connected to the main frame. An adjustable actuator interconnects the swing arm to the main frame to control the movement of the swing arm with respect to the main frame. A pair of discs are mounted to the free end of the swing arm for rotation with respect to the swing arm. The discs are offset mounted with respect to one another and are angled outwardly with respect to the direction of travel of the implement. The discs form grooves for receipt of fertilizer. Fertilizer tubes are mounted adjacent the discs and terminate behind the discs with respect to the direction of travel. The fertilizer tubes deposit fertilizer in the grooves formed by the discs. A furrow closer is attached to the main frame to close the groove opened by the discs.

A fertilizer-application method comprises (a) receiving an aqueous solution of a cyanamide compound into a heated segment of a hydrolyzer; (b) allowing the cyanamide compound to hydrolyze in the heated segment, thereby forming an aqueous cyanamide hydrolysate (ACH); (c) allowing the ACH to cool under pressure; and (d) applying the ACH, after cooling, to soil.

Disclosed is an agricultural air injection apparatus including: a compressor for compressing air; an air tank which has a pressure gauge and a safety valve for presenting overpressure and stores compressed air of high pressure in a set pressure condition; a decompression valve for decompressing air pressure discharged from the air tank; a sprayer for spraying water in a particle state in order to make vapor contained in the supplied air; a distributor which uniformly distributes the decompressed air to a plurality of flow paths and has a control valve to open and close the flow paths; an air supply pipe which is buried in the soil where crops to be cultivated will be planted and has pores for supplying air passing through the distributor; and a controller which is connected to the compressor, the pressure gauge of the tank and the control valve of the distributor to control supply of the compressed air.
