Ingredients of Eudrakon N
This fertilizer consists of 3 components ensuring a multilayer nitrogen supply:
- Urea resp. Carbamide
Ammonium is absorbed instantly and mainly by water plants, but on the other hand, it can not be stored. Due to energetic reasons, it is slightly easier to absorp ammonium than nitrate. But higher nitrate concentrations diminish the ammonium absorption (from approx. 5 mg/l nitrate).
Excess ammonium is quickly oxidized by oxygen consumption into nitrate by nitrifying bacteria. Therefore the fertilizer has a relatively low amount which also helps to avoid toxic ammonia when the pH-value rises above 7.5.
Here, the second content, urea is able to resolve the problem. Urea, a nitrogenous end product of the nitrate metabolism of many animals, can be directly absorbed by plants on the one hand or also hydrolyzed by the bacteria in the tank into ammonium and CO₂.
Nitrates are non-poisonous for animals with all common pH-values and therefore also used as a “storage” here.
Some plants may react with disturbances of growth when a nitrate-rate of 10 mg/l occurs. Therefore, this rate does not need to and should not be exceeded.
A part of the nitrate is added in form of its potassium and magnesium salts, as not only potassium, but also magnesium is consumed in quantity in pools that use a lot of nitrogen.
Daily max. 1 ml per 50 l tank water until the requested concentration is reached.
The optimal concentration is about 3 - 8 mg/l nitrate. Any more is not necessary and only supports the growth of algae.
When no absorption takes place by the plants and there is a complete mineralization, a dosage of 1 ml to 50 l water corresponds to a direct dosage of 2 mg/l nitrate, 0.4 mg/l potassium and 0.1 mg/l magnesium.
6.8 % nitrate, 2.02 % potassium, 1,0 % urea, 0.48 % magnesium, 0.34 % ammonium, methyl paraben, EDTA
