Magnesium sulfate as fertilizer: instructions for use, composition

Few gardeners know about the benefits of using magnesium sulfate fertilizer for plants. The substances contained in its composition have a positive effect on the growth and development of vegetable crops. Top dressing will also be useful for indoor flowers, since macronutrients restore the plant's immunity, improve its appearance and increase the duration of flowering. Epsom salt is also used for preventive purposes.

Magnesium sulfate is available as a white crystallized powder

What role do magnesium and sulfur play in plant development?

In the garden, magnesium sulfate is vital. It improves the taste of vegetables and fruits, increases the yield. Supports immunity, which is very important for young seedlings, and reduces the adaptation process after planting in a new place.

Important! Magnesium sulfate takes part in photosynthesis, it is responsible for the color of foliage, active growth and development of garden and indoor culture.

It is more expedient to introduce magnesia into the soil together with mineral complexes, then the plant will better absorb nutrients in the form of nitrogen, potassium and phosphorus.

Mg is especially beneficial for garden plants such as tomatoes, potatoes and cucumbers, as it increases the production of starch and sugar. For all other crops, it helps to better absorb the nutrients that they need for life, namely:

  • fats;
  • essential oils;
  • calcium;
  • vitamin C;
  • phosphorus.

In addition, magnesium has an anti-stress effect. It protects the leaves from direct sunlight, prevents the root system from freezing, and the fruits from spoiling.

Any vegetation with a lack of magnesium becomes extremely sensitive to external environmental influences.

Signs of a lack of trace elements in plants

In fact, magnesium sulfate is extremely important for all garden plantings: vegetables, flowering shrubs and fruit trees. But feeding is recommended only when the plant is deficient in magnesium and sulfur.

You can understand that this moment has come by the following signs:

  1. The appearance of chlorosis on foliage, when a characteristic marble pattern is drawn on them.
  2. A change in color of the sheet plate, it becomes a boring shade and begins to dry and curl.
  3. Active foliage discharge indicates a critical lack of magnesium.
  4. On fruit trees and shrubs, fruits do not ripen or shrink, in which case the plants also lack potassium.
  5. Slow growth and development is a clear sign of poor absorption of sulfur, discoloration of foliage also indicates that the plant is deficient in this element.

Mezhilkovy chlorosis is the first sign of magnesium deficiency

With an insufficient sulfur content in the soil, the activity of soil bacteria decreases. It is from their vital activity and activity that the amount of nutrients the plant will receive depends.Actually, therefore, it is important to monitor the sulfur level, the indicator should vary within the range of 10-15 kg per 1 ha. This is exactly how much is needed for the garden plantings to fully grow, develop and bear fruit well.

The use of magnesium sulfate for plants must be approached carefully. Incorrect dosage can negatively affect the plantings. Sulfur with an insufficient amount of oxygen is converted into hydrogen sulfide, and it, in turn, is detrimental to the root system of the plant.

Attention! Magnesia crystals lose their properties upon contact with direct sunlight, their substances simply disintegrate into components. It is necessary to store fertilizers in a dark box.

Composition and properties of fertilizer magnesium sulfate

Magnesium sulfate is a valuable source of Mg ions and sulfur, these elements are necessary for all types of plantings in the garden and indoor flowers. Fertilizing plants with magnesium sulfate ensures better absorption of many nutrients, including potassium and phosphorus. And they are responsible for the development of the root system.

The composition contains:

  • sulfur (13%);
  • magnesium (17%).

These figures may vary slightly depending on the manufacturer. It is a white or light gray crystalline powder. It dissolves well in water at room temperature.

The low hygroscopicity of the composition allows the powder to be stored outdoors, but it should be protected from direct sun and precipitation.

Magnesia acts as an “ambulance” for horticultural crops that are deficient in magnesium. In addition, the substance helps to regulate the protein content in fruit shrubs and fruit trees, as well as in their fruits.

How to use magnesium sulfate for plants in the garden

Vegetables need magnesium feeding during the growing season. The solution is prepared strictly according to the instructions, each culture has its own dosage:

  • tomatoes and cucumbers - 30 g per 10 liters of water;
  • carrots and cabbage - 35 g per 10 liters of water;
  • potatoes - 40 g per 10 liters of water.

After the liquid is poured under the root of the plant, and the perimeter of the trunk circle is also treated. To stimulate growth, water the soil with a magnesium solution every two weeks.

The use of magnesium sulfate for fruit and berry crops

Magnesia helps fruit trees and berries to better endure the winter period, makes them more frost-resistant and resistant to temperature fluctuations.

Foliar top dressing with magnesium sulfate is carried out in the fall. Proceed according to the following instructions:

  1. Mix warm water (10 L) and powder (15 g).
  2. Stir everything thoroughly.
  3. Introduce 5 liters under one shrub, 10 liters under an adult tree.

Before adding magnesia, it is necessary to deoxidize the soil, this is done by liming

In the spring, fertilizers are applied directly to the soil. This is done to increase the yield and quality of the fruit. The powder is laid in specially made grooves, then sprinkled with earth and watered abundantly.

How to use magnesium sulfate for indoor plants

At home, magnesium is used to improve the process of photosynthesis. Most often, there is insufficient lighting in an apartment for the normal development of a flower, and the less light it receives, the more it consumes macronutrients.

This type of feeding has a unique feature - it does not pollute the substrate, unlike many of its counterparts. That is, the remnants simply remain in the ground until the flower again lacks it.

It is necessary to dilute pharmacy magnesium sulfate for plants strictly according to the instructions. But for flowers, the concentration should be higher than for vegetables.

How to use magnesium sulfate for feeding conifers and ornamental plants

For conifers and ornamental trees, magnesium is needed. The fact is that chlorophyll, which is vital for them, is obtained by photosynthesis. And this process directly depends on magnesium.Fertilization with magnesia promotes the emergence of new apical branches and the growth of green mass.

Important! Before magnesium fertilizing, the soil is liming without fail; in an acidic environment, green spaces absorb substances poorly.

Top dressing is carried out in early May. To do this, mulching the near-root zone with powder, hay or fallen needles is carried out, then even the most severe frosts will not be afraid of the root system. You can also prepare a solution of magnesium sulfate in ampoules; any option is suitable for plants.

Application of magnesium sulfate fertilizer for flowers

Epsom salt is used as a fertilizer for flowering crops, so it is actively used in indoor floriculture.

Spraying with magnesium sulfate solution improves the appearance of indoor plants

Regular feeding increases the resistance of flowers to diseases, pest attacks, and increases resistance to harmful environmental influences.

In addition, feeding with magnesium sulfate has a positive effect on the quality of flowering and its duration.

Instructions for the use of magnesium sulfate for indoor flowers

As a rule, detailed recommendations on how to prepare and use the solution for plants are in the instructions for use of magnesium sulfate. Loose powder can be taken in its pure form - it can be applied directly to the soil. You can dilute, and then spray the bushes with a ready-made solution or carry out foliar dressing. To do this, take 10 g of powder in 5 liters of warm water. The soil is watered once a month, the flowering culture during flowering is carried out more often - once every two weeks.

Professional advice

Magnesia sulfate can be added together with other agrochemicals. Agronomists recommend applying fertilizer while preparing the soil for planting seeds.

In autumn, it is best to add magnesia to the soil in its pure form, and then dig it up with mineral complexes. During the winter, the salts will dissolve and the substrate will take on a form in which the root system of young seedlings takes root and adapts much faster.

Due to the fact that the drug does not inhibit vegetation, it can be added together with pesticides.

Magnesium sulfate has a positive effect on the yield and quality of fruits

Attention! When using an aqueous solution and dry powder, do not forget about safety measures. Magnesia can cause itching, redness and allergic reactions (hives).

Conclusion

The benefits of magnesium sulfate for plants are invaluable, fertilizers affect growth, appearance and fruiting. It can be used in any soil, but it is especially recommended to apply the powder to acidified areas where an increased concentration of nutrients is required.
