The importance of fertilizing with magnesium

| Polish Market |

Magnesium content of most Polish soils is low. It is therefore necessary to take into consideration the fact that plants require this element. If it is supplemented, unnecessary losses in yield volume may be avoided.

Why is magnesium deficient in the soil?

As opposed to potassium and calcium, magnesium is easily washed out into the deeper parts of the soil structure and groundwater. However, in our climate zone this nutrient, alongside calcium, constitutes a basic element of the absorption complex. In other words, its content and appropriate concentration makes it possible to absorb it better. The more magnesium is dissolved in the soil mixture, the more likely it is that the plant, especially the fresh roots, will absorb it.

Excessive rainfall, especially in light soils, causes faster washout of Mg2+ ions. Periodic droughts also make it more difficult to retain magnesium in the soils, as they cause the easily accessible form of magnesium to turn into a form which is more difficult to absorb by the plants. Light soils are not the only location of the problem – magnesium is also washed out from the heavy soils.

The importance of magnesium for the plantations

Magnesium is indispensable for the proper functioning of the plant, as the element takes part in such functions as photosynthesis, breathing and protein synthesis. Fertilization with magnesium increases nitrogen absorption and is favorable for the deposition of phosphorous in the seeds.

Magnesium deficit in the plants may lead to slower growth, interfering with appropriate development of roots and their efficiency. The application of magnesium is done both by fertilizing the soil and the leaves – once the plant has grown. The deficiency of the element decreases the absorption of nutrients from the soil (phosphorous and potassium in particular), weakens the resistance of the plant to diseases, as well as impoverishes the biological value of the yield.
