Magnesium fertilizers – does magnesium matter in plant cultivation?

Magnesium stimulates the development of the root system. Without it, the basic plant physiological processes – such as mineral uptake and photosynthesis – are impossible. Being a component of chlorophyll, magnesium affects the regulation of plant photosynthesis processes and energy metabolism. It improves the use of nitrogen, potassium and phosphorus absorbed by the plants, improves the quality of protein and reduces nitrate content. Magnesium taken up by plants has a beneficial effect on the transportation and accumulation of phosphorus in the seeds. Moreover, its content significantly affects the condition, resistance and development of plants. It also affects fat, protein and carbohydrate synthesis and takes part in the transportation of assimilates.

The lack of magnesium during the autumn crop vegetation results in the inhibited growth of roots, and consequently, the entire plant. On the other hand, magnesium deficiency in spring makes it difficult for plants to absorb and use nitrogen. Magnesium deficiency causes poor plant growth, decreased resistance to diseases, delayed plant developmental phases and a reduced yield. Magnesium fertilizers are therefore necessary for all crops. The plants which are most susceptible to magnesium deficiency include cabbage (rape), root crops (sugar and fodder beets, potatoes), cereals (winter and spring), corn, broad beans and many vegetables, such as tomatoes, cucumbers, lettuce, pumpkin, bell pepper and root vegetables. Magnesium fertilizers supplement the deficiencies of this component, which is necessary for the proper growth of plants and creating optimal soil conditions for them.

Remember!

  • Over 33% of soils in Poland are characterised by insufficient magnesium content
  • Magnesium improves vegetable protein quality
  • Magnesium is a regulator of plants cation-anion balance!
  • Magnesium deficiency in the intensive growth and yield creation phases reduces the accumulation of organic compounds in seeds, tubers and roots, which significantly reduces the yield
