Masz racje Robert,sa "dosc" bogate,nie wiem na ile rozni sie nawoz z skladem w All in One od "starego makro i mikro"
Z Marianem znam sie jeszcze z przed czasow "fejsbokowych"kiedy rozmawialismy o jego dozowaniu,on pytal o moje ,na tle naszych wspolnych zdjec itp.,to jego nawozenie mikro opieralo sie o sklad blisko zblizonym do CO2.art ,ktory nie odbiega zbytnio od csmb .Trzeba wziasc oczywiscie pod uwage,ze wtedy nawozil akwarium na bazie zwiru.
Posiadalem pierwsza serie nawozow,jak Piotr wstawil na zdjeciu,kiedy dostalem na testy,co moge powiedziec...to na tamtym etapie mojego zbiornika bez rewelacji z problemami z Fe (nie pomagalo zmniejszenie dawek)musialbym rozdzielic mikro od Fe,przypuszczalnie "mialem troche rzeczy w podlozu"
Natomiast co do samego Boru w jego przypadku to chodzi o mlode szczyty,jesli zauwazylbys ,a moge Ci to zagwarantowac nie mial praktycznie nigdy problemu z "paleniem szczytow" wlasnie przez wysoki bor ,czyli nie przekracza jeszcze granicy ,gdzie to moze isc w druga strone.
Jesli natomiast szukalbys opini o B itp. to musialbys skontakowac sie z Lawrancem czy tez z Happim ,sa to osoby ktore poswiecily na badanie jednogo pierwiastka mikro okolo roku czasu.
Sam uzywam obecnie mikro na bazie soli nie chelatow z wyjatkiem oczywiscie Fe.
Widzialem ostatnio Twoja kowersacje z Diana Walstad dotyczaca K ,przykladowo odnosnie bielenia szczytow jak wspomniales moze byc powodowane "nadwyzka K"
to tutaj masz cos od Lawrenca:
"Is this the reason aquatic plants, such as
Ludwigia “red” and
Rotala “Singapore”, become more red in the presence of extra trace dosing? If so, then this is an indication of heavy metal stress, not actually a sign of plant health, since these plants grow well even without extra traces dosing.
I speculated about this a few months ago when I observed L. “red” become less red as traces were reduced. I knew that plants couldn’t use most of the trace metals that were added so something was happening to cause them to increase their anthocyanins content and reduce them as traces were reduced.
Since anthocyanins reflect red light, which is why they appear red, and high light intensities with sufficient red light is capable of inducing the production of these pigments, the increased metabolic activity may cause the excess production of free radicals, which are toxic oxygen molecule species. In order to protect their cells from these free radicals – they are free because the oxygen is not bound to any other atom or molecule – plants increase anthocyanin production to bind them, thus preventing oxidative stress which can damage leaves.
Oxidative stress can result in obvious symptoms like leaf burn, such as the necrotic spots on this Golden Pothos plant which was subjected to toxic concentrations of iron:
Tutaj konkretnie :
The excess iron in plant tissue in the presence of high light intensities causes the rapid production of free radicals which kills the cells resulting in necrotic spots in the leaves. If light intensity were lower, the plant’s physiological mechanisms would be sufficient to process the free radicals and no visible symptoms of toxicity would occur.
Not all plants are capable of producing anthocyanins. Rotala rotundifolia “green” is such a plant and it also happens to be the most sensitive to poor growing conditions. Here it is with small, stunted and deformed leaves:
Tutaj np. B w niedobor oraz toksycznosc:
These pictures of two stems of Liminophila aromatica were taken 18 days after dosing high levels of boron. The newest leaves are twisted and deformed, and the growing tips have died off. It appears very similar to the symptoms of boron toxicity
Here is a picture of the first stem (back left) taken just 5 days before, 13 days after the boron experiment. The leaves show normal growth patterns. (The white leaves of the stem on the right shows iron deficiency chlorosis from being grown in inert sand while the stem on the left is grown in nutrient-rich clay.)
Why did it take so long for excess boron to adversely affect L. aromatica? Perhaps it’s due to the thickness of the stems which can hold high concentrations of nutrients for use later, or perhaps it was due to chronically high levels of boron which the plant could no longer tolerate.
Rotala sp. “Vietnam”
The topmost leaves are translucent and some bend downward against the normal growth. The red stems lost their color. These symptoms were observed less than a day after dosing less than 1/120 tsp of Borax, Na₂B₄O₇*10H₂O, into my 60 gallon tank. Two days later, the growing tips died off. A couple of more days after that, the plants broke off mid-stem. These symptoms may be the result of a boron toxicity.
Also interesting is that these same symptoms resulted when I dosed potassium silicate, K₂O₃Si. Since silicon and boron are utlized for proper cell wall structure, excess or deficiency directly affects its growth.
The concentration at which an element becomes toxic is not absolute – it is often relative to all other elements. In this case, since I was dosing extremely lean traces, the excess boron probably resulted in toxicity due to it’s relatively high concentration. Thus, any statement that a certain concentration of an element is safe or toxic cannot be made without knowing what this concentration is relative to.
Ludwigia “red” boron deficiency
Here’s what a deficiency of boron looks like in Ludwigia “red” (aka: “super red”). The symptoms appear only on new growth characterized by small, hard leaves that are severely deformed. This is due to the impairment of leaf expansion. The color is also very intense, probably because B deficiency doesn’t impair the production of anthocyanin pigments. You can compare this to the older growth which has normal leaf expansion.
This plant is considered one of the “easy” plants to care for. It typically tolerates a wide range of conditions. It’s also one of the most tolerant of excessive trace dosing. When I dosed excessive amounts of boron that caused toxicity in other plants, this plant took advantage and grew very fast.
Trzeba rowniez dodac,ze wysoki Azot moze wplynac na blokade Cu oraz B .
Sorrki,ze troche poza tematem ale na pewno Cie to zainteresuje
...chociaz juz Ci to podawalem na grupie whatsaap
