• fertilizer for plant nutrition is either introduced directly into the soil or delivered to the plant zone by irrigation or laying fertilizer granules near the plants.
• the disadvantage of this procedure is the low productivity, the difficulty of standardizing feeding, and in the case of using liquid fertilizers, the need to prepare solutions from concentrates sold through the distribution network.

• the disadvantage of this sprayer is its low quality. dispersions, unstable outflow of an air-liquid mixture, large losses of expensive fertilizers.
• the problem solved by the author was the creation of a compact device for finely dispersed aerosolization of liquid fertilizers for use in households - in a room, small greenhouses, on a personal plot.
• the essence of the proposed solution to the problem lies in the use for spraying fertilizers and plant nutrition of aerosol cans of a cylindrical shape, in which a mixture of liquid fertilizer with repellent is loaded.

• a mixing device is installed inside the can.
• a paddle mixer or an Archimedes screw can be used mounted on the tube with the possibility of rotation around a central axis.
• Option 1 is used when suspensions or other compositions are used as fertilizers for storage that form several phases: for example: solid, liquid and gas-liquid phases.
• Option 2 Spray is recommended when using fertilizers as solutions containing ingredients that can cause corrosion during long-term storage, in particular due to the partial destruction of its structure or due to the presence of corrosive impurities in its composition, which is typical for some nitrogen - and / or sulfur-containing fertilizers.
• a design feature of such a canister is that the inner surface of the body is made of an insulating polymeric material, for example, Teflon or polyethylene.
• This solution can be realized as a result of using a coating applied to the metal or as a result of the housing being made of the above material.
• Option 3 Spray is recommended when using systems that are sensitive to external influences as fertilizers, for example, bacterial fertilizers, which are a suspension of microorganisms in a liquid medium, containing nutrients and protective environment. Such systems, as a rule, are sensitive to external influences and are prone to decontamination.

• Spraying using the device according to options 1-4 is carried out holding the can with the lid up, when using the device according to option 4a, the can is turned upside down.
• inventive device allows both point feeding of individual plants and fertilize at the same time individual groups plants. At the same time, as the experiments showed, the consumption of fertilizers is reduced several times and the feeding efficiency is increased.
• inventive spray cans are economically advantageous, because reduces specific chemical consumption by 5-10 times.
• inventive cans makes it possible to obtain an aerosol system having a minimum droplet size that cannot be obtained by atomization, and to standardize the processing technology.
• the preparation located in the can is not in contact with the oxygen of the air, which allows it to maintain its performance for a long time.
• the aerosol can is compact and convenient for storage at home.
• Example 1 To determine the biological effectiveness of foliar root cans from aerosol cans according to option 1 with a device that improves mixing of the liquid inside the liquid as compared to direct leaf watering, an experiment was conducted on the treatment of Celandine plants (Chelidonium majus L). For processing, aerosol containers with a diameter of 65 mm and a volume of 0.5 L were used; nitrogen was used as a propellant. Watering cans were used for ordinary leaf watering. As a fertilizer The mixture used was a 1% solution of the industrially produced fertilizer Zelenit-1.
• the weight of the aerial part of the plant was 680 g / m2, in the experiment 900 g / m2.
• the weight of the aerial part of the control was 830 g / m2, in the experiment - 1500 g / m2.
• the processing method using aerosol cans increases the biological efficiency in this case by 60% compared with conventional irrigation.
• Example 2 In order to determine the biological effectiveness of treatment from aerosol cans without a mixing device and with smooth inner walls according to Example 4, experiments with medicinal borage (Borago oficinalis L) were carried out in comparison with conventional leaf irrigation. As a fertilizer mixture (working solution) was used a solution of fertilizer "Zelenit-2" available on the market.
