Advantages of using the Aquarius sprayer and carbamide-ammonia mixture (UAN)

UAN is a modern liquid fertilizer consisting of a mixture of three forms of nitrogen (nitrate, ammonium and amide).

Benefits of using CAS

  1. Nitrate is responsible in this mixture for an instant effect. It can be taken up by plants immediately.
  2. Ammonia becomes nitrate due to nitrification.
  3. Amide under the action of soil bacteria turns into ammonium.

This combination creates the effect of prolonged feeding, which starts immediately after application and continues for some time, depending on the activity of bacteria and soil temperature. An additional plus – there is no free form in UAN that can be released as vapor into the atmosphere. The presence of the ammonium form makes it necessary to think about sealing the application site, since dry and hot weather can contribute to the loss of nitrogen from the application site. But even in this case, liquid fertilizers show excellent results, in comparison with solid – 10% loss in liquid, versus 30-40% in granular.

The liquid form has found its way into use due to a number of advantages:

  1. It's easier to maintain the same application rate on every hectare of land being treated.
  2. It is possible to mix several working substances in one container (pesticides, herbicides, fungicides are added to UAN). In one pass of equipment across the field, the effect of several treatments is achieved at once.
  3. UAN is optimal for foliar feeding of plants during those periods when their root system cannot cope with the load.

The application of liquid fertilizer makes it technologically easier to accurately maintain a given application rate per unit area. But this should be followed by a special technique – therefore, the self-propelled sprayer "Vodoley" was developed, equipped with an on-board computer with a GPS module and an electronic fertilizer supply system.

Foliar and UAN

Foliar nutrition is needed for plants at the stage when there are already sprouts. Conventional machinery after passing through the field will leave a lot of damaged plants. To safely process plants, the Aquarius sprayer Equipped with low pressure tires. They exert pressure on the soil of 100-160 g/cm2, therefore, after passing through the field of such a technique, the plants rise for 2-3 days. The operation of the pump is synchronized with the speed of movement of the equipment across the field, so even if the latter slows down or accelerates, the desired level of application of UAN per hectare remains the same.

From the solution on the leaves, the amide form of nitrogen is absorbed first. Drops that fall on the ground will become ordinary soil fertilizer. CAS allow you to quickly adjust the nutrition of plants in those moments when there is intensive growth, and the root system cannot cope with the needs of the plant.

CAS Terms

An important benefit of UANs is that they do not pollute the environment. There is also an improved nitrogen uptake during drought. Another plus – UAN is not flammable and explosive (unlike saltpeter in bags).

CAS applies in the following terms:

  1. Autumn – basic tillage.
  2. Spring – pre-treatment. It is optimal to make it with the Aquarius sprayer, which, thanks to its tires, can enter the field on wet soil before the rest of the equipment.
  3. Spring – during the growing season. And again at the height of "Aquarius" - its tires allow you to pass through the field with plants, leaving little to no damage. During this period, you need extra roottop dressing and treatment with fungi and insecticides.

Agronavigator "Aquarius 2" thanks to the parallel driving function, it allows you to apply fertilizer precisely to those areas where they are not yet available. When hitting an already treated area, the place of re-treatment is immediately highlighted on the screen so that the sprayer driver can correct the trajectory of the equipment.

Liquid fertilizer can be mixed in the same tank with other plant treatment components. Therefore, in one pass through the "Aquarius" field will process several substances at once, which is cost-effective and saves the site from unnecessary passages of equipment.
