The application of some liquid fertilisers directly onto your crop canopy as spray droplets can cause damage (phytotoxicity); a stream of liquid directly onto the soil may be preferred in these instances.

There are several streaming nozzles available that can produce single or multiple streams in a variety of spray widths. As with other hydraulic nozzles, streaming nozzles come in a range of sizes to achieve different flow rates at a range of pressures.
