Good day, dear reader of Aquablog, with you, as always, Andrei Selitsky and I, as promised, have prepared for you the second part of the article on mineral nutrition for plants. I published the first part of this article a few days ago and unfortunately no one has yet responded in comments about the quality of the laid out material.
I hope this is due to the lack of a permanent readership and in the near future I think readers will start commenting on posts and will ask me questions by email. Well, okay, Moscow was not built right away, we will wait a bit and everything will be fine.
If you remember, in the first part of the article I talked about the trace elements in the aquarium and what important role they play. Today I want to switch macronutrients, since their influence on the aquarium will be more significant than microelements. And I’ll probably start with phosphorus.
This macro is considered one of the most important in the aquarium and it is needed quite a lot. What is phosphorus for? The fact is that he takes an active part in the expenditure and supply of energy, and as a result, he actively synthesizes proteins, fats, vitamins, carbohydrates and enzymes.
Among other things, this macro element takes an active part in the respiration and nutrition of plants.
I want to note the importance of phosphorus – it is the main part of ATP, or the so-called adenosine triphosphate, and it, in turn, is almost the main energy source for living organisms. Most of the phosphorus accumulates in young plants.
A pronounced sign of a lack of phosphorus is the darkening of the leaf color, leaves and young shoots begin to curl, reddish-brown spots appear on older leaves. Potassium, calcium or magnesium salts of orthophosphoric acid are best used as fertilizers.
Calcium salt of orthophosphoric acid, or superphosphate has found wide application. A formula like this: (Ca (H2PO4) 2 * H2O). Well, or something like that …
I want to note one thing: it is very difficult to determine the lack of phosphorus in an aquarium. For this reason, when there is a shortage of mineral fertilizers in aquariums, aquarists add complex fertilizers to the aquarium water, which also include phosphorus.
The next very important element for the normal existence of aquarium plants is potassium. This macro element accumulates in young shoots of plants and is involved in the synthesis of carbohydrates and enzymatic processes occurring inside the plants. Since the aquarium is an isolated environment, it may happen that potassium is not enough in water.
Basically, all the necessary nutrients that the plants need are fed into the aquarium together with the feed and with the substitute water. As a rule, the lack of potassium manifests itself in the form of the appearance of yellow and brown spots on the tips of the leaves. As well as phosphorus, potassium is added to the aquarium in the form of complex fertilizers.
If you can find it, you can add monosodium potassium phosphate. This is an excellent thing, because in this substance there is both phosphorus and potassium at the same time and it is easily absorbed by plants.
When adding it to the aquarium, take a dose at the rate of 2-3 grams per 100 liters of water.
In addition to the above macronutrients, we need such a thing as calcium. As a rule, aquarium plants rarely need to be replenished with calcium.
If you have not yet guessed, calcium determines the hardness of the water, and as a result, no calcium deficiency has ever been observed in our water. Only in soft water, where hardness is close to zero, in such water plants will experience calcium starvation.
But I want to calm you down – you will rarely see a lack of calcium in the water, or you will not see it at all.
Magnesium, just like calcium, is a macronutrient. This element is an essential thing in the metabolism, especially in young plants. The lack of magnesium in water is observed much more often than calcium.
Magnesium ions, like calcium, will significantly affect water hardness. But as a rule, if in an aquarium it is necessary to increase the rigidity, then aquarists are content with only calcium. However, in such cases, magnesium starvation may begin in aquarium plants, which will subsequently manifest itself in the formation of white spots on the veins of the leaflet, which will later cause the disintegration of the tissue of the leaf plate.
Therefore, if you need to increase the hardness of the water in the aquarium, it is better to use both magnesium and calcium for this purpose in order to avoid the undesirable effects of magnesium starvation.
Very often, experienced aquarists include silicon as macro elements. What is this item for?
It turns out that it is part of the skeleton of most land plants, which ensures the strength of their stems. But aquatic plants, since they are in a suspended state, they do not feel an acute need for silicon.
Silicon consumption by amphibious plants increases when the plant enters the air. In aquariums, I never heard about the lack of silicon.
If you decide to create a real underwater garden with a large number of aquarium plants, remember that half of the success depends on the correct choice of aquarium soil. I remind you that the wrong substrate can ruin all your attempts to create an excellent aquarium that will take your breath away.
This concludes the story of the importance of macro-elements in aquarium water and how they will influence the development of plants in our banks. I think I have highlighted all the important questions, and if I forgot something, write in the comments, I’ll be happy to answer everyone.
Be sure to subscribe to blog updates, after a couple of days there will be another interesting article, although I have not yet decided on the subject, but nothing. The main thing is that it will be, and there the matter is already in small.
