Magnesium nitrate (or as this compound is also called - magnesium nitrate) is an excellent fertilizer for plants. It is magnesium nitrate that is used to ensure that plants receive the necessary amount of a trace element such as magnesium, as well as nitrogen, which is necessary for plant growth and health.
Chemical formula
The fertilizer used is not just magnesium nitrate, but magnesium nitrate for 6 water molecules. The formula of the compound is as follows: Mg (NO 3 ) 2 · 6H 2 O. It is this compound that is called magnesium nitrate.
Application
A solution of magnesium nitrate is used as a fertilizer, since it contains magnesium and nitrogen, which are so necessary for plants. The advantages of using this particular compound is that the solution does not contain harmful contaminants, and is also completely soluble in water. Also, magnesium nitrate can be used in combination with other fertilizers, for example, calcium nitrate. The advantages include the fact that the solution is quite simple to use.
What are the benefits for plants
Magnesium nitrate is the most commonly used substance as a fertilizer. But what is its use manifested in? It should be noted that magnesium is an extremely important microelement for plants, since it is it that is the main atom in chlorophyll. That is why it is so necessary that plants do not lack this element.
It is necessary so that the growth process goes faster, and cells divide more often. In addition, magnesium maintains the required level of protein and has the effect that plants can absorb phosphorus, which is also necessary for them.
If the plants have magnesium hunger, then leaf necrosis is possible, as well as a smaller yield. But this does not mean that they always need magnesium. If there is an excess of it, then this will entail the digestibility of other trace elements, for example, K and Ca.
If the plant is in soil with high acidity, then most likely it experiences magnesium hunger, since under such conditions this microelement cannot be fully absorbed.
Magnesium nitrate is one of the best compounds used for root feeding of various plants, vegetables, berries and fruitful crops. Most often, fertilizer is used with drip irrigation. The advantage of this method is that it allows the use of fewer nitrogen fertilizers.
Application doses
Before fertilizing the plants, it is necessary to conduct some tests to make sure that this will not cause more harm. It depends on the environment of the soil, on the territorial location of the site. Also, a lack of magnesium can be judged by crop. If after harvesting, its quantity decreased from 40 to 50%, this may indicate that plants lack micronutrients.
If foliar feeding is used, then you should try the concentration of magnesium nitrate solution from 1 to 4%. If the root (that is, it brings with the water that the plant is watered), then it is necessary that the concentration is much less - from 0.01 to 0.2%.
