This article will be helpful to those looking for a way to improve the efficiency of irrigated potato cultivation.
The problem of secondary soil salinization is becoming more and more urgent. On farms where irrigation is used, you can see "salt spots" on the soil surface. How does this threaten culture? The increased salt content in the irrigation water increases the osmotic pressure of the soil solution, which complicates the absorption of nutrients, prevents the development of root and vegetative systems, inhibiting the growth of plants. Lack of harvest due to salinization leads to economic losses of the farm.
Such problems require systematic integrated work, including soil reclamation and other agrotechnical methods, including: fertigation with soil bioforming. Fertilizing Agriful with irrigation water is a great way to cope with surface salinization and prevent the situation from getting worse in irrigated areas.
In one of the large farms in the Rostov region, Agriful Plus was added in 2020 with drip irrigation (5 liters per hectare per growing season). After the first application (phase "leaf development - budding") at a dosage of 2,5 l / ha (per 1000 liters of water), surface desalinization of the soil occurred. The visual effect was impressive. The video is on our instagram - @ agroliga.ru.
The second and third application of Agriful per drop was 1,25 l / ha during the budding period and after flowering, respectively. The cost of the issue is minimal, and, as a result, the soil will always thank the one who treats it carefully and carefully.
What are the unique properties of Agriful Plus? All components of the preparation are of 100% vegetable origin. This is the most fulvic acid-rich bioferment in the line of the Spanish manufacturer Agritekno. Betaines regulate osmotic pressure and improve nutrient availability. Fulvic acids increase the activity of the biological microflora of the soil and develop the root system. Polysaccharides, a complex of vitamins and an increased content of organic matter (45%) regenerate the development of soil microflora and restore fertility. Recommended doses for the growing season: 5-10 l / ha Agriful Plus.
In OOO Energia, Proletarskiy district of Rostov region, in addition to fertigation and pesticide treatments, fertilizers were used for potato leaf nutrition:
- Tekamin Max Plus - to overcome the effects of herbicidal stress and 2 l / ha was applied fractionally after flowering. The drug is completely environmentally friendly due to its plant origin. The increased content of organic matter (60%) and free L-amino acids (12%) improves plant growth, increases the growth of tubers and their quality, which ultimately contributes to obtaining a uniform fraction of potatoes.
- Controlfit Cu (copper) - to increase resistance to fungal and bacterial diseases. The fertilizer has no analogues in Russia and is 100% environmentally friendly (it comes in the form of copper gluconate, this is the only form of copper existence inside the plant). Copper is an enhancer of photosynthesis. The peculiarity of Controlfit Cu is that the drug moves along the xylem and phloem, systemically protecting the plant.
In the first treatment, we added 2 l / ha in the phase of full germination of 15 - 20 cm, then 1 l / ha was applied after flowering and during the growth of tubers together with fungicides. Compatible with fungicides and insecticides.
- Teknokel Amino B (boron) Plus - in the budding phase 1 l / ha for the growth of shoots and the root system, the prevention of scab, as well as a balanced diet, since its deficiency reduces the absorption of nitrogen and calcium.
- Teknokel Amino Ca (calcium) Plus - fractionally 1 l / ha from the end of flowering to the middle of the tuber growth period in order to improve the quality of the peel and keeping quality.
- Teknokel Amino Mix (mix) Plus - 1 l / ha to eliminate micronutrient deficiencies and increase plant immunity during the period of tuber growth. These mineral nutrition correctors with free plant-based amino acids act through the enzyme system and stimulate plant growth and the development of generative organs.
- Controlfit RK (potassium phosphite) - 1 l / ha to improve product quality and increase resistance to fungal diseases. It is a fast source of phosphorus-potassium nutrition, it contains 30% phosphorus and 20% potassium. Due to the increased content of phosphites (20%), it increases the production of phytoalexins, which increase the protective functions of plants in response to their damage by pathogens. Controlfit RK is a systemic product, therefore it moves both up and down, performing preventive protection of plants from diseases.
The scheme of the field experiment is shown in Table 1.

Many agricultural producers are concerned about the question: how does the pH of the working solution affect the effectiveness of pesticides? Potatoes are not wheat, where 2-4 treatments are carried out during the growing season, there are only up to 13 fungicidal treatments per season, and they are extremely expensive, therefore it is important to control the pH and hardness of the water, as well as to know the optimal pH of the working solution when working with pesticides to get the most bang for your buck.
A convenient and high-quality way to control water quality is to use the Teknofit pH conditioner. It binds hardness salts so that they do not cause alkaline hydrolysis. The water used for spraying almost always does not meet the necessary requirements - it is usually very hard and has an alkaline reaction, which reduces the effectiveness of the active ingredients of pesticides. Teknofit pH simultaneously acidifies alkaline water, softens hard water, reduces the surface tension of water, improves the penetration of working solutions into the sheet and eliminates foaming. The color indicator colors the water when the acidity level changes, which makes it easy to determine the required dosage without the use of special devices. In each specific case of using a particular pesticide in the preparation of a working solution, there may be subtleties, so you should carefully read the label of each drug and work on the quality of the water.

In 2020, the Agritekno potato feeding system made it possible to obtain an additional crop (with a guarantee of the ecological safety of products) in two farms of the Rostov region:
- LLC "Energia" - increase made 4,7 t / ha in comparison with the result of the control plot (on the control they used plant protection products + standard farm nutrition scheme), net profit - 42520 rubles / ha (excluding investments);
- JSC "Shakhaevskoe" - increase of 7 t / ha in comparison with the result of the control plot (in the control, only SPR treatments were carried out), net profit - 69030 rubles / ha (excluding investments).
Why did the same leaf power schemes give different gains? Energia LLC already uses Teknofit pH in its fields, and a lot of "nutrition" was introduced in their control plot. At Shakhaevsky, we took pure control in order to assess the increase solely due to our scheme.
Due to the use of plant raw materials, the preparations are characterized by a high content of organic substances (up to 60%) and a balanced aminogram, which completely coincides with the natural aminogram of plants. When physically extracting (extracting) raw materials, only moderate temperatures are used, which excludes hydrolization and denaturation (decomposition) of the components. Plant extracts are preserved.
Agritekno products have international certificates Ecocert (EC), OMRI (USA) and are approved for use in environmentally friendly agriculture.
Agroliga Rossii Group, the exclusive distributor of Agritekno in Russia, has been operating in the Russian market for 18 years and during this time has earned a reputation as a reliable supplier of original field crop seeds, plant protection products, fertilizers and agrochemicals from the world's leading manufacturers.
