The underestimated nutrient

In fertilizer planning, there is a high focus on nitrogen, phosphorus, and potassium. But what about magnesium? It's worth taking a closer look at the functions of this nutrient in the plant. Magnesium has great potential for optimizing growth and yield formation.

Magnesium (Mg) is an essential plant nutrient and has many functions in the plant - in the leaves, roots, and yield organs, such as the ears, cobs, pods, or beet bodies. Magnesium, for example, protects against stress factors such as drought, heat, or high solar radiation. Moreover, as the central atom of chlorophyll - the leaf green - magnesium is involved in photosynthesis. Magnesium therefore supports the formation of carbohydrates. These are needed throughout the growth of all plants.

But plants need magnesium not only to form carbohydrates, but also to remove them. Magnesium is part of an energy complex that loads the plant's pathways. This is how carbohydrates are transported from the leaves to the parts of the plant that need them to grow.

With magnesium deficiency, this transportation is disturbed. Carbohydrates accumulate in the leaves and do not reach their destination. The roots and yield organs are no longer adequately supplied. This effect on root growth occurs in all crops - in addition to wheat, for example, also in corn, canola and sugarbeet.

In all crops, a magnesium deficiency first leads to impaired root growth, some time before deficiency symptoms are evident in the above-ground parts of the plant.

Simply explained

Why do plants need magnesium?

An important tool - the KALI-TOOLBOX App

If you want to track down nutrient deficiencies in the field, we recommend the KALI-TOOLBOX app. With this app, you can identify the deficiency symptoms directly on site via your smartphone or tablet. Besides many informative pictures, the free app provides the appropriate nutrient recommendations.


Magnesium ensures yield and quality

Magnesium is crucial for a good harvest. Plants need this nutrient for photosynthesis and the transportation of carbohydrates for yield formation and root growth - and therefore for better water and nutrient supply during drought. Moreover, magnesium protects plants from stress factors such as strong solar radiation or heat. Magnesium should therefore always be included in needs-based fertilizer planning for soil and foliar application.
