Agrotechnical requirements for sprayers

A modern sprayer consists of many components, each of which should work without fail. The main requirements for it are directly related to the quality of field processing. All nodes that may come into contact with the working fluid must be resistant to chemically aggressive fertilizers. The application process itself must be accurate over the entire area of the field.

The rod of the sprayer

The quality of processing of the field with liquid fertilizers or plant protection products and ease of operation depend on the design of the sprayer boom and its fixation mechanism. The possibility of processing at different heights, damping vibrations, protection of communications and sprays from damage in case of collision with the ground or with obstacles should be provided.

What pumps are used for sprayers in agriculture

The market of the pumps for sprayer today is represented by membrane-piston, centrifugal and piston (less often). The former work better with chemically aggressive and abrasive fluids, the latter have fewer components, which makes them more reliable, the last - piston ones with a small size make it possible to obtain the highest pressure.

Tank for working fluid of the sprayer

The capacity of the sprayer tank is always indicated along with the boom size. It is also important what is the material of the tank - plastic is unpretentious and cheap, stainless steel is more expensive, but much stronger. If the tank is made of ordinary steel, it is very important to monitor the condition of the anti-corrosion coating, because some fertilizers are very aggressive to metal.

How does humidity and temperature affect spraying quality?

High temperatures and low humidity are fraught with significant waste of the working fluid for evaporation. An air column above one hectare 50 cm high at 20° is capable of dissolving more than 85 liters of water. If the humidity is 50%, then half of this value. How do you like the loss of 40 liters of the herbicide at a rate of 50l/ha outflow due to evaporation?

What height of the sprayer boom is better

Every 10 cm of lifting bar above the ground increases the loss of plant protection from wind drift and evaporation by 2 times. But the higher boom is, the less likely the collision of the boom with the ground. And what if you additionally increase speed of the droplets of the working fluid using the air flow?

How often do I need to change spray nozzles on the sprayer?

Only certified sprayers have real fluid flow rates differing from those stated in documents by less than 10%. During field work, the fluid flow expands the dimensions of the internal channel and the flow rate increases. Therefore, you need to monitor its value and promptly change the nozzles on the rod.

Choose sprayers (nozzles) for spraying under a specific rate of outflow

Only spray nozzles of certified manufacturers have a consumption close to the value specified in the documentation. The fluid, passing through the internal channel of the spray nozle, expand internal channel size, which over time, in an unpredictable manner, changes the flow rate of the liquid. Therefore, you should regularly check and, if necessary, change the sprayers.

What is better - to reduce the concentration of the solution or the rate of outflow?

If you are going to reduce the dose of a substance by reducing of the outflow rate, then you are risking to throw money down the drain. It is better to dilute the same dose in a larger volume of liquid, reducing the concentration of the working solution. To maintain an outflow rate of less than 200 l/ha, spray nozzles forming small droplets will be needed, which are highly susceptible to wind drift and evaporation.

Single-flare spray nozzle and Twin-flare spray nozzles - which ones for what?

Quality of processing of the current culture depends on the correct selection of a sprayer. Twin-flare are good for processing spikelets, weeds of the same height as the crop, but if you need to «punch» the entire thickness of greenery and reach the ground, use sinle-flare nozzles.

Pressure in the working system of the sprayer and processing quality

It is necessary to take into account the fact that to obtain at any pressure strictly identical droplet size is impossible. Rather, we can talk about the spread of the size of the droplets, the range of values that can be in the range from 10 to 700 microns.

25% compensation for self-propelled sprayer «Vodoley» and a set of refitting of seeders for liquid fertilizers usage

When buying a «Vodoley» self-propelled sprayer and a set of additional equipment for seeders for liquid fertilizers usage the farmer receives compensation of 25% of the cost in accordance with the resolutions of the Cabinet of Ministers of Ukraine No. 130, 86 and 106.

How often should I flush the sprayer after work?

Mandatory flushing of the entire supply system of the working fluid after each application extends the service life of both the sprayer as a whole and its entire equipment.

Choosing a self-propelled sprayer

What do we expect from a self-propelled sprayer?

Modern sprayers should be equipped with a computer that controls the spraying process.
They must be distinguished by high maneuverability, since they have to start working on the sodden soil in early spring.
Off-road work places high demands on the reliability of the chassis.
Easy to repair if need be.
Ability to work in all weather conditions.

Urea Ammonium Nitrate UAN-32

UAN is a mixture of aqueous solutions of ammonium nitrate and urea (in the ratio of 35.4% urea, 44.3% nitrate, 19.4% water, 0.5% ammonia water). The density of liquid fertilizer to 1.34 kg/m3.

Mineral fertilizer UAN

One of the weighty reasons to buy UAN is the higher economic efficiency of UAN solutions compared to solid nitrogen fertilizers, which is explained by the increase in labor productivity and the low cost of nitrogen contained in the fertilizer.

UAN application for winter and spring crops

Urea - ammonia mixture, fertilizer UAN can be used for all crops, but the most appropriate - for cereals as the main fertilizer or dressings.

Precision Farming - Resource Farming

The development of resource-saving technologies in agriculture will allow the industry to reach a qualitatively new level of production, which will allow (with certain changes in state policy supporting agriculture) agricultural producers to compete with foreign enterprises.

Nuances of winter nitrogen nutrition

Half of all world agrocenoses are cereals, of which winter crops prevail. In countries with developed agriculture, wheat is the basis of the diet of the majority of the population. Wheat is capable of producing high yields in a wide range of latitudes and climatic regions.

Fertilizer classification, their properties

Classification of fertilizers, their properties. The enormous importance of fertilizers in improving soil fertility and crop yields has been proven by numerous experiments of scientific institutions, and also confirmed by the practice of world agriculture.

The advantages of using the sprayer «Vodoley» and the Urea Ammonium Nitrate (UAN)

Self-propelled sprayer «Vodoley», equipped with an on-board computer with a GPS module and an electronic fertilizer feed system, is designed to work with liquid forms of fertilizers. An important plus of UAN is that they do not pollute the environment.

Rent of a sprayer for introduction of liquid fertilizers, UAN-32 and PPP

For one-time application of liquid fertilizers, the optimal solution would be to rent a «Vodoley» sprayer with an on-board computer.

Buy a sprayer or order a re-equipment of seeders

To make a starting fertilizer, you need a seeder working with liquid fertilizers, if it doesn’t able to do this, then you can order a re-equipment of the seeder for applying liquid fertilizers. For foliar and root introduction of CAM, utility services or plant protection products need a self-propelled sprayer «Vodoley».
