Mineral fertilizers (tuki) – it is artificial fertilizers, vypuskayoemy the industry, which soderzhat depending on a look nitrogen, a fosyofor, potassium, magnesium, basic elements of a food, and also microcells.
Ammoniac saltpeter – the main nitric fertilizer. It is ammoniac nitratnoe the fertilizer, one of the most raspyorostranenny. Is issued preimushcheyostvenno in the form of white small balls (granules). Bring in the spring before crops or a poyosadka, widely use for podkormok. To apply before perekopky a site in the autumn it is not recommended, as with a precipitation it is washed out deeply to the soil and ground waters.
Ammonium sulfate – sernokisly ammonium. On appearance – it is melyoky kristalliki glaucous cveta. Contains 20-21 % of nitrogen. For podkormok to apply only in case of lack of saltpeter.
Sodium saltpeter - is good under all cultures. It is recommended preiyomushchestvenno for sour soils. It is impossible to mix with superphosphate, it is possible – with potash fertilizers. Legkorastyovorima, is quickly acquired rasteniyami, is good for podkormok. Not rekomenduetsya to apply this fertilizer on soyolonets as containing in sodium is mute even more worsens these soils.
Calcic saltpeter - one of the best nitric fertilizers – a source not only nitrogen, but also a kalyyotsiya. Reduces the content of nitrates, accelerates emergence of lateral lashes on cucumbers that is important for increase uroyozhy.
Urea – highly effective bystroyodeystvuyushchy superficially active fertilizer, especially in podkormkax, both root, and extra root. It is necessary to be careful when using in the protected soil, at a low osveyoshchennost, when a low intensivyonost of photosynthesis.
The phosphoric. Superphosphate - happens simple poroshkoyovidny – gray, almost neslezhivayushhijsya a powder.
Potassium sulfate – is used under cultures, chuvstvitelyyony to chlorine: potatoes, grapes, yagodyony cultures.
Potash saltpeter – operates at the same time and as azotyony (13 % of nitrogen) fertilizer.
Potash salts – red and yellow crystals, it is appreciable slezhivayutsya. Soyoderzhat to 30-40 % of potassium. To bring luchshe before perekopky a site in the autumn under those cultures which love sodium: root crops, cabbage.
Kalimagneziya – is recommended to be brought under potatoes and under all vegetables.
The complex (combined) fertilizers. They represent naibolyyoshy value for truck farmers as contain some elements of a food and are very often enriched with mikroudobreyoniya. However their use uslozhnyaetsya that often to them is necessary dobavlyat simple fertilizers, that dovesti quantity of separate elements to a demanded ratio. They can be brought under all vegetable and bakhchevy cultures in different terms on all types of soils.
Ammofos (ammofoska) – it is applied under all vegetable, plodoyovo-berry and decorative cultures in various zones on any soils. Priyogoden as for the main introduction (under perekopku soils), priposevny (in ryadki, holes, grooves), and for podkormki plants during vegetation. Nityoroammofoska – contains on 17 % azota, phosphorus and potassium. It is the mix of ammiyoachny saltpeter made by industrial way, ammofosa, diammofosa, chloride ammonium, sulfate of ammonium and potash saltpeter; not slezhivaetsya.
It is well acquired by plants, prigodna for the main introduction and podkormok.
Nitrofos – double nitrogen-phosphorus fertilizer, contains do38 phosphorus and nitrogen %. It is a mix precipitata, superphosphate, ammofosa and ammiachyony saltpeter. Unlike nitroammofosa about 50 % of phosphorus are in a water insoluble form therefore ispolzuetsya it is exclusive as osnovyony fertilizer in the spring or in the autumn at perekopke soils. To carry out them podkormki it is inexpedient.
Potash saltpeter – physiologically alkaline nitrogen-potassium fertilizer. It is used under all vegetable cultures on all pochvax in the autumn and in the spring under the main obyorabotka (180-260 g/m2) and in top dressing (45-60 g/m2): for liquid podkormok 35-40 g of fertilizer dissolve in 10 l of water and spend for 4-5 m or on 10-15 plants of rassadny cultures.
