Can I use a mixture of two sales
Now in Russia on narrow ridges grown produce thousands of growers - fans. More of those who would like to move to this technology, but for whom the stumbling block is the need to prepare a mixture of fertilizers. Many people do not know how to approach this, and would prefer to buy ready-mix, especially a mixture of 2.
Demand is known, gives rise to the proposal. In different areas, where growers have to apply the method Mitlaydera begin selling a mixture of 2.
Can be treated with confidence in selling blends?
The answer is ambiguous. Industry currently produces mixtures of 2 does not, although such plans are developed. Industrial production of granulated fertilizers required composition would have been a complete solution to the problem, but until the mixture is prepared artisan. Therefore, one name can not rely.
The products must be certified with an indication of any mixture of fertilizers prepared and what is it the percentage of nitrogen, potassium (K 2 0), phosphorus (P 2 O 5), magnesium and trace elements. For phosphorus, in addition to its total amount should be specified the content of water-soluble form.
If the finished mixture contains at least 13-13,5% nitrogen and the same amount of potassium, phosphorus, if there is a water-soluble form and not less than 8-8.5%, if the magnesium is not less than 1.5-2%, and boron, and molybdenum of 0.025-0.05%, the composition of the mixture corresponds to the name and can be used. It is hoped that written on the label correctly reflects the composition of that pour into the packet. It is not so much a direct filsifikatsii as the fact that when large amounts of fertilizer mixing is almost impossible to achieve uniformity of their distribution, and there is no certainty that you buy a bag got everything you need in the correct proportions. Therefore it is better to sell is not ready to mix, and a set of ingredients in separate packages. Mix thoroughly before using them directly, you get a homogeneous mixture of the desired composition.
If the fertilizer is sold under the name of a "mixture of two Mitlayderu", but the amount of nutrients in the mix is not specified, then it is likely that this is not an accidental omission. Or a mixture of poor quality (eg, dilute with a high proportion of water-insoluble phosphorus, which are all mixtures prepared on the basis of nitrophosphate), or it does not correspond to the original recipe. Under the title "mitlayderovskih" sometimes there are fantastic mixture of the composition of unbalanced nutrient elements, the use of which may undermine the credibility of the method.
Online there are also organic and organomineral fertilizers, which are touted as more effective and better suited for our soils than blend Mitlaydera. This method of advertising suggests that the mixture prepared according to recipe Mitlaydera already began to be perceived as a model of fertility, and it pleases. As for the fertilizer itself, for vegetable production on narrow ridges, they do not fit, if only because they can not be used for fertilizing during the growing season. Basis for a successful vegetable growing on narrow ridges - a fractional power of growing crops in small doses is easily digestible nutrients, and it can only be accomplished with a mixture of balanced fertilizer.
Now the market appears complex fertilizer "Kemira wagon" the Finnish company "Kemira Agro", which contains nitrogen, phosphorus, potassium, magnesium, boron, molybdenum, and in addition, five other trace elements (iron, copper, zinc, manganese and selenium) and does not contain chlorine. The fertilizer is sold in a package of 5 kg. If a 5 kg "Kemira Wagon", add 1.25 kg of ammonium nitrate and 3 g of molybdic acid, we obtain the relation in nitrogen, phosphorus, potassium and magnesium, and the desired concentration of molybdenum. This mixture can be described as "A mixture of 2 Super», as it compared with a mixture of 2 contains excessive amounts of boron and 5 additional micronutrients. "A mixture of 2 Super» can be used as a preplant fertilizer (along with a mixture of a) on soils with low content of trace elements: the peat soils drained upland swamps, on sandy and sandy loam soils, on soils with a long period of time have made only the N - P - K - fertilizer on some old garden soils.
Use "A mixture of 2 Super» for fertilizing vegetative cultures is not recommended. The concentration of copper and zinc in it is quite high (about 0.1%). Since these elements are practically not leached from the soil with repeated dressing by making their content in the soil may rise to undesirable high level. In addition, the mineral soils Nechernozemie excess will be included in the mixture of iron and manganese (these components may be useful in any alkaline soils).
A mixture of 1 has also appeared on the market. Its composition is so simple (see Table 9). That the only danger lies in the uneven mixing boric acid with lime fertilizer. It is therefore better to the package of dolomite or limestone powder by weight of a bag attached to the right amount of boric acid.
If you start working on the narrow ridges of the purchase mixtures 1 and 2, and you have that - that went wrong, the board of one - try to make the mixture yourself. It's not as difficult as it may seem.

Hello Otvette, please, in the preparation of a mixture of very granular fertilizer alone, others in the powder. One thing that they do not mix. For example powder (potassium chloride) is below, amiachnaya nitrate (in grains) at the top. Make does not work uniformly, and dissolved in different ways. Granules much longer is necessary to make the next feeding, and some of the old is not dissolved. I started to grind grain into powder, and all fertilizers one consistency. Is this correct?. Thank you.
