Eco potassium is a chlorine-free fertilizer obtained as a result of processing sunflower husks. It has a high content of potassium, magnesium and sulfur. Able to quickly reduce the acidity of the soil, which needs liming. It is a means of prolonged action: the granules slowly pass into a dissolved state, in which minerals can be absorbed by plants.
POTASSIUM WITHOUT CHLORINE
It is known that when growing potatoes, there is a significant removal of potassium from the soil. Losses are compensated by the introduction of potash fertilizers. At the same time, potash fertilizers may contain chlorine, and experts evaluate the effect of this element on the development and yield of potatoes in different ways. Most note that an excessive concentration of chlorine ions in plants leads to a decrease in the content of chlorophyll, a decrease in the activity of photosynthesis, which causes a delay in plant growth and, as a result, a deterioration in the quality of tubers, a decrease in the volume of collections.
As confirmation of this idea, we present the results of a study conducted on the fields of the A.G. Lorch. The experts used two different combinations of fertilizers (on soil with pH=5 and with an average content of exchangeable potassium of 128mg/kg):
- ammonium nitrate + ammophos
- potassium chloride;
• ammonium nitrate + ammophos - eco-potassium.
Both in the first and in the second case
the same amount of potassium was applied (135 kg/ha for active substance), but in the areas where eco-potassium was used, more
high yield.
A series of experiments was also carried out with different doses of fertilizer application and analysis of the dry matter and starch content in the tubers. On the
Based on the results obtained, recommendations for use were formulated.
MESOELEMENTS
In terms of composition, eco potassium fertilizer (0 : 5 : 37 + 10Mg + 12S + ME) is comparable to potassium magnesia (0 : 0 : 32 + 12Mg + 20S). One can note the high content of sulfur (an essential element for the plant: if the potato lacks sulfur absorbed from the soil, then protein synthesis is difficult). Attention is also drawn to the increased concentration of magnesium, the need for which in potatoes is no less significant.
Magnesium belongs to the elements suitable for recycling (reused by plants), and its deficiency is even visually easy.
determined by the lower leaves of the potato (they acquire a pale green color, necrotic spots appear). According to the content of nutrients in potato tubers and tops, their absorption by plants can be calculated using the following formula:
MICROELEMENTS
Fertilizer eco-potassium contains the following trace elements (according to AI): Fe 0,53%, B 0,25%, Zn 464 mg/kg, Cu 252 mg/kg.
Table 1 shows data that can be used to preliminarily estimate the amount of microelements that potatoes take out during
the entire growing season.
However, it is wrong to focus only on this information: in practice, ready-made templates for plant nutrition are inoperable,
because any land mass is unique - both in terms of the availability of each individual element, and in a number of factors affecting
to absorb these elements. The most correct approach is to calculate the required amount of nutrients, focusing on the results of an agrochemical analysis of the soil and taking into account the planned yield. And then decide on the application option, correctly assessing the technological capabilities of the farm, namely the availability of equipment that allows foliar feeding at the right periods of plant development.
In some cases, it is better to introduce meso- and microelements into the soil as part of the main, prolonged-acting mineral fertilizers. And in the future, according to the results of diagnostics during the growing season, make only adjustments with top dressing.
One of the advantages of applying to the soil is the direct supply of nutrients to the root system of plants. This is first of all
eliminates the possible acute deficiency of meso- and microelements during the growing season.
TALK ABOUT PRICES
The growth rate of prices for mineral fertilizers makes farmers think about the need to save. But in order to achieve
reducing costs, it is not necessary to reduce the volume of purchases and lose the volume of grown products - it is enough to carefully analyze the proposals available on the market.
For example, as our experts did on the eve of the 2021 season. They calculated the cost of 1 kg of active ingredient for different types of granular fertilizers. The price included transportation costs for delivery to the farm (+ 2000 rubles/t in physical weight).
Only for macronutrients, the average price (in rubles per 1 kg of AI):
• 0:0:60 36,67 (potassium chloride)
• 0:5:37+10Mg+12S 48,7 (eco potassium)
• 10:26:26 50,0 (diammofoska)
• 14:14:23 52,9 (nitroammophoska)
• 0:0:52+18S 88,4 (potassium sulfate)
A similar calculation can be made for granular fertilizers containing meso- and microelements by comparing the potential costs of, for example, potassium magnesia and eco potassium.
Of course, prices for each position will change, but the ratio will remain the same. This data, as well as information about the composition of the fertilizer, will help you make an informed rational decision. And if it is in favor of eco-potassium, it will definitely be in favor of the future harvest.
