Name of the invention: fertilizer salt sprayer = - -;

The present invention is an apparatus for spraying aqueous fertilizer salt solutions.

For fertilizing soil crops, it has hitherto generally been customary to use the artificial fertilizer, i.e. one or more plant nutrients either sprinkle salts in powder form or dissolve them in water and pour this solution over the bottom piece. The latter method requires two operations, namely dissolving the salt and pouring the solution, in some In the case of cases, the third step is topping up with pure water.

In contrast, the present invention combines all of these operations while making the device convenient to use and for this purpose uses the following known principle, which consists in that a liquid or a gas on a solid body flow along a certain chemical composition and The practical application of this principle is has already been done in practice in several cases, e.g. as a "soap stone" for washing your car or as an inhaler pen, with which the air to be breathed is enriched with menthol or other substances.

The fertilizer salt sprayer that can be screwed onto a water hose consists of a flow device in which a solid body, a Kind of stone made of fertilizer salts, is washed around by the flowing water and dissolves in the process, so that the one emerging from a nozzle aqueous solution the fertilizer salts in a certain concentration

contains and immediately above the piece of soil to be fertilized, e.g. a lawn that can be sprayed - for that in many cases Any further refilling with pure water that is required does not need to be changed on the flow device, because afterwards the salt stone has completely dissolved, the pure tap water sprays from the nozzle.

The middle piece of the fertilizer salt sprayer consists of a relatively thick-walled plastic tube into which the salt stone is inserted. At both ends of the tube there is a thread that is used on one side for attaching a hose connector and on the opposite side (at the front) for screwing on a spray nozzle A sieve disc at both ends of the middle section prevents the salt stone from sliding out during the flow of water.

The salt stone is produced either by melting it a suitable mixture of fertilizer salts and solidification of the melt in a suitable form or by pressing the salt mixture under high pressure in a suitable form.
