Potatoes are a magnesium-demanding crop. With a yield of 50-60 t/ha, 60-70 kg/ha of magnesium oxide is removed from the soil. In the soil, most of the magnesium is in a hard-to-reach state, the lungs are especially poor in terms of the granulometric composition of the soil. That is why effective magnesium fertilizers are always included in the technology of advanced farms. After all, this is a direct effect on the volume of the crop and the starch content in the tubers. The need for magnesium can increase with high doses of potash fertilizers, since potassium and magnesium are antagonists.
On acidic soils, when applying Omia Magprill (contains 25% calcium and 9% magnesium), not only the physical and chemical properties of the soil improve due to the neutralization of excess acidity, but also the nutrition of plants with calcium and magnesium. The action of OMIA Magprill as an ameliorant and fertilizer lasts for several seasons (depending on the dose and method of application), and the primary effect occurs from four weeks after the application and dissolution of the drug in the soil. This is possible due to the micronized (in the form of finely ground powder) form of natural dolomite from which the product is made. After grinding, 2-6 mm granules are made from the powder, which greatly simplifies the technological application and allows the use of Omia Magprill both randomly and locally.
In 2021, Omia Magprill at a dose of 300 kg/ha was tested in the cultivation of potatoes without irrigation in the Yaroslavl region. The variety Gala was grown on sandy loamy soil. The yield in the control was 28,2 t/ha, in the variant with Magprill - 30,8 t/ha, which is 2,6 t or 9,2% more.
Product | Dose, kg/ha | Product costs, rub./ha | Yield increase, t/ha | Cost of additional crop, rub./ha | Additional income, rub./ha |
Magprill, KFH "Magro", Yaroslavl region | 300 | 8487 | 2,6 | 26000 | 17513 |
The increase in yield occurs both due to the overall increase in the mass of tubers, and due to the greater yield of a large fraction, which is a necessary quality indicator for marketable potatoes.
The calculations used the current price for Omia Magprill and the average long-term price for potatoes - 10 rubles/kg. The resulting increase in yield covers the cost of applying the product and allows you to get an additional income of 17513 rubles/ha.
We wish you high, high-quality, economically viable potato crops!
