Company «Compehensive AgroService» (kas32.com) performs works of the application to soil of the UAN (carbamide-ammonia nitrate) and works on agrochemical protection of plants (a safe alternative to air-chemical protection) using the self-propelled sprayer «Vodoley» produced by Energomekhkomplekt JSC (Ukraine) analogue of the Rosa sprayer.
UAN is a mixture of aqueous solutions of ammonium nitrate and carbamide (in the ratio of 35.4% of carbamide, 44.3% of saltpeter, 19.4% of water, 0.5% of ammonia water). Density of liquid fertilizer to 1.34 kg/m3.
The only nitrogen fertilizer that contains three forms of nitrogen:
Thus, UAN provides prolonged nutrition of plants with nitrogen. In view of the absence of free ammonia in the UAN, it does not evaporate into the atmosphere when applied, but the presence of an ammonium form still makes the minimum embedding of the soil desirable, especially in high temperature and with dry soil after application.
UAN provides the lowest cost of nitrogen. Nitrogen losses during application of UAN do not exceed 10% of total nitrogen, while when applying granular nitrogen fertilizers they reach 30-40%.
One of the most important advantages of UAN application is its high adaptability:
The need for foliar fertilizing is determined by the following factors:
In conditions of low temperatures or lack of moisture in the soil, the absorption of nutrients significantly slows down. Often critical periods regarding the lack of macro- and microelements in cereals occur in the phase of exit into the tube - ear. Due to the intensive, rapid growth of the vegetative mass, the reserves of readily accessible nutrients from the soil are exhausted or their assimilation by the roots of plant "does not keep pace with the rates of plant growth." In such a situation, foliar insertion of the UAN is necessary.
The degree (percentage) and rate of assimilation of nutrients from liquid fertilizer UAN through the leaf surface is much higher than when assimilated from fertilizers introduced into the soil. The amide form of nitrogen quickly penetrates through the leaf surface of cereal grains and other crops. Feeding through the leaves is advisable to combine with the introduction of microelements and (or) plant protection products. UAN is, first of all, a very flexible additional tool for feeding crops in a highly efficient production. It allows you to adjust feeding in the key phases of plant development for correction, strengthening of missing factors in the development of plants and obtaining the required characteristics of marketable products (protein, gluten, brewing barley, etc.).
In addition to all the above benefits, UAN does not pollute the environment, improves nitrogen consumption during drought, the operating costs for its application are significantly lower than other fertilizers. UAN is non-toxic, non-flammable and non-explosive, (compare with dry nitrates in bags). UAN provides high accuracy of application rate.
Summarizing the advantages of applying UAN vs granular fertilizers, it is possible to note such advantages as:
Sprayer «Vodoley» - light high-performance machines on elastic wheeled propellers with ultra-low pressure tires. When developing the «Vodoley» complex, the priority task was to reduce pressure on the soil when carrying out work on introducing liquid fertilizers and pesticides. The result was a machine that creates ultra-low pressure on the soil (100-160 g/cm2.0.01-0.016 MPa), which allows us to use these aggregates on wet, waterlogged soils and in fields with crop plants in the tillering phase without forming a technological track. This property, which distinguishes the machines of the «Vodoley» complex from traditional equipment, allows to significantly expand the period of their work, especially due to the earlier (for 2-3 weeks) the beginning of spring field works and to reduce the timing of agrotechnical measures from weather conditions.
1 Sprayer «Vodoley» has no analogues to ensure optimal agrotechnical terms for the introduction of fertilizers and plant protection products - the most important component of precision farming technologies. Work is provided with solid and liquid types of fertilizers and plant protection products for plants with a stem height of up to 0.5 meters on low-bearing soils, in fields with a complex microrelief, and also directly on crop plants without crop damaging.
2 Ultra low pressure on the soil allows:
3. Confirmed by operation compliance with the declared technical characteristics.
4. Key components (determining the technical level) - from the world's leading manufacturers.
5. Wide possibilities for adapting the equipment to weather conditions and the required parameters of processing quality: maintaining the required dose of working fluid irrespective of the speed of the sprayer (the design is patented in the Eurasian Patent Office), the use of wear-resistant sprayers with the ability to control the droplet size and the coating density of the surface to be treated The required technology of work.
6. Ecological compatibility - reduction of harmful load on the environment due to the maximum use of advanced technologies for pesticide application at high operating speeds.
7. Self-propelled sprayer «Vodoley» has been tested by the State Scientific Institution "Ukrainian science and research institute predicts that technology for technology and technology for the Sylksodorsky vibrobitveva. Leonid Pogorilov ", received the Certificate of Conformity.
8. Self-propelled sprayer «Vodoley» passed state tests and entered into the State Register of technical means of application of pesticides and agrochemicals, which are allowed for use on the territory of Ukraine, received a registration certificate from SE "UkrCTV".
Machines of the «Vodoley» complex are ideally suited for soil-saving farming technologies, such as No-Till, Mini-Till, etc.
