Magnesium sulfate is widely used in agriculture as a high-quality effective fertilizer. The composition contains very important for the growth of gardening, ornamental crops: oxides, copper, sulfur and other trace elements. The inorganic substance is known by other names - magnesium sulfate, magnesia, Epsom salt.
Signs of magnesium deficiency in plants
The lack of this element is more common on sandy soils. The main symptom of a lack of substance is weak growth, with different cultures this manifests itself in different ways.
- In the apple tree, this moment is called magnesium starvation. Symptoms are similar to iron deficiency; the leaves of the apple tree begin to turn yellow. Gradually leaves frown, become arcuate with ragged edges. First, magnesium starvation appears on old leaves, later on young ones.
- On stone fruit trees, the lack of the sulfuric acid element causes premature yellowing, shedding of leaves... The leaves of pears take on a black putrid hue. Currant bushes are deformed, begin to bend downward.
- The lack of an element in strawberries or strawberries can be determined by the state of the leaves. Appear yellow streaks on the leaves, they may turn red later. If you don't notice this in time, the leaves of berry crops dry up.
- Plants have stunting... Small buds, unripe fruits are formed. The aerial part of the plants suffers greatly, as the lower leaves turn yellow.
In order to avoid the above reasons, it is necessary to carry out regular feeding.
What magnesium gives to plants
An important trace element, participates in the growth of vegetable and fruit crops. Due to the lack of an inorganic element, the root system suffers. In addition to magnesium, it is necessary to remember about potassium, these substances complement each other well.
Deficiency has a detrimental effect on the yield (the fruits become smaller or fall off). Magnesium is main source of energy, its abundance triggers important plant life processes.
If the feeding composition is too small, the growth of the root system is inhibited. Roots lose the ability to get moisture from deep soil layers, which is especially dangerous in dry summer.
A clear lack of useful composition appears after 10-15 days. A deficiency of a substance is found on the lower leaves - this happens because the content of this trace element decreases inside.
If you have a magnesium deficiency, it is most severe the root system suffers plants.
Composition and purpose of fertilizer magnesium sulfate
The main components are sulfur and magnesium, they take an active part in photosynthesis plants, without this process culture cannot develop. Therefore, the role of these components is very important. Complex feeding, an indispensable preparation for successful crop production. Thanks to its use, you can achieve a significant increase in yield.
Main characteristics:
- produced by the appearance of small crystals;
- the color of the crystals is white, sometimes grayish;
- crystals are completely dissolved in water;
- the powder requires protection from direct sunlight;
- the shelf life of the magnesium-containing substance is not limited.
Impossible to overdose, since the plant takes as much magnesium as it needs during its growth. Its excess improves the quality of the soil, contributes to high yields.
Mechanism of action
This amazing element is involved in the process of photosynthesis. The role of magnesium in plant life is very important, accumulating in the embryos, it provides enhanced growth, affects the maturation of the fetus. Magnesium also acts as a catalyst.
Due to its content, the correct assimilation of phosphorus, calcium by vegetables and fruit and berry crops occurs. Simply put, fertilizer provides the plant with the necessary influx of important substances... In the process of such a mechanism, growth is accelerated, the quality of the crop and the taste of the fruits improve.
Useful supplementation with magnesium increases the amount of vitamins, trace elements, starch, and sugar.
Advantages and Disadvantages Compared to Other Products
This fertilizer is successfully applied on many farms and garden plots. Experienced gardeners have noted the following benefits:
- the beneficial substance additionally contains sulfur;
- increases efficiency the use of nitrogen fertilizers;
- the element has a fairly rich range of uses;
- by its action neutralizes toxic impurities carbamide biuret;
- combined with other fertilizers that contain nitrogen, phosphorus;
- can be used for feeding almost all cultures.
Among the shortcomings, only one point can be distinguished - an excess prevents the absorption of calcium, potassium, manganese by plants. This trouble can be avoided if the proportions of fertilization are correctly observed.
Instructions for use
Sulfur-magnesium dressing is applied in a standardized manner, according to the instructions, the fertilizer ratio depends on the composition of the soil, geographical location and type of plants. Top dressing is carried out during the growing season 2 times a month... It is better to dilute in warm water.
- for pre-sowing treatment take 10 grams of substance per square meter;
- for root feeding 30 grams of powder and 10 liters of water;
- to spray the leaves with the same amount of water, 15 grams will be needed;
- when planting seedlings of fruit trees, 30 grams are applied at the root;
- for berry bushes, it will be enough to put 20-25 grams under the root.
When fertilizing root crops after the main application of magnesium, the soil must loosen up... Observing the application rates, you can avoid an excess of this substance in the soil.
Safety measures when working with the tool
When working with any agrochemical substance, safety measures must be observed. Use gloves, prepare the solution carefully, avoid contact with eyes. Wash hands thoroughly after handling. Use a respirator when spraying plants. No smoking.
Compatibility with other drugs
Combination with other fertilizers has a positive effect... The fertilizer is easily absorbed by the root system and improves the chemical composition of the plant.
Storage conditions and shelf life
During storage, it is necessary to carefully monitor so that the powder does not spill.
The storage location should be protected from access of children and animals... The shelf life of the substance is not limited.
The use of magnesium sulfate fertilizer is a very important point when caring for vegetable, fruit and berry and flowering plants. Due to the depletion of the soil, its qualitative composition deteriorates, therefore, any type of agricultural activity requires additional fertilizing. Thanks to this approach, you can get a good harvest every season!
