Hello Stephen,.
so far I have not really scientifically handled the whole thing. It has funktiniert and I was satisfied. I measured once or twice with Bernhard, but according to the correspondence and found some stuff, I just like to here instead. I don't know unfortunately - because I'm new - whether and how you can post links or PDF's, otherwise I would have what by the Landwirtschaftskammer NRW's Forum to my favorite fertilizer "Wuxal". I type's off time:
Manna Wuxal super
2% carbamide, 2.3% nitrate, 3.7% ammonium 8% = total nitrogen
8% phosphate
6% potassium
Metal cations chealtierte with EDTA + boric acid
Conductivity of the respective degrees of dilution (mS/cm = EC)
0, 5ml / l (0.0005%) = 0.3
1ml / l (0.001%) 0.5 =
1, 5 ml / l (0,0015%) = 0.8
2ml / l (0.002%) = 1
4 = 10ml / l (1%)
50ml / l (5%) = 18
100ml / l (10%) = 33
200 ml / l (20%) = 61
undiluted solution of fertilizer (100%) = 272
I use almost exclusively in the range of 1-2ml / l, which corresponds to an EC of 0.5-1 Wuxal and had no trouble in Amorphophallus. Since I am fortunate for me to have Very much soft, almost lime-free tap water, the pH of the finished is
Solutions on the basis of already slightly acidic reactive fertilizer, always in the range of about 6. 1 ml/l solution is, how Bernhard has already correctly "I-pasted", also a permanent casting possible, without damage to the plants.
Measurement of excess pouring water in the coasters, I noticed, that the water with an EC of 1,424 and a pH = 5.73 in the ideal range is also already acquifers as the fertilizer solution itself. I think here is the aforementioned enrichment of salts, which, however, as the measurement shows, obviously be washed out with the water. The pH-value is easily slipped in the acidic range, what has the presence and the gradual reduction or the recording of the Carbamats and of ammonium nitrate as a reason.
I not pass while on any scientific claim, especially since I made only one hand measurements, but I got all in all normal and plant-friendly values. Add
the Wuxal with EDTA addition, (ethylene diamine tetraacetic acid) is überchelatiert, i.e. even in a sub-optimal pH range plants should be still well able to take corresponding ion. So also no deficiencies or similar can be identified visually. The only difference is, as you already did with the brilliant image, root growth.
And as far as the Sphagnum, so that would not be worth for me. Seramis holds such A lot water, that I shower only every 7-10 days depending on the temperature. It is already still damp enough fine roots to educate A few grain layers beneath the surface after the period. Also the idea would not liked to mix something organic in wet clay granules, because I am going back up the risk of decay so. As Bernhard has also "I-pasted", I have moved once about one-third of my soil mixture with Seramis + 10% sand + approx. 55% standard soil, what worked well has. Since I'm now but in pure clay granules and more find the result, I not so soon start using organic components.
Best regards,
Simon
