Key benefits

MacroSpeed® Green is a mineral fertiliser based on kieserite (magnesium sulphate monohydrate), providing readily available magnesium (Mg) and sulphur (S) in a high-content, water-soluble form (+25 MgO +50 SO₃) for efficient crop nutrition. A balanced magnesium supply supports the effective utilisation of nitrogen, contributing to stable crop growth and improved nutrient use efficiency.

As magnesium is the central component of the chlorophyll molecule, MacroSpeed® Green stimulates chlorophyll synthesis and photosynthesis, enhancing the plant’s ability to convert light energy into biomass and supporting vigorous crop development.

The fertiliser promotes root system development and function by supporting energy transfer and carbohydrate transport within the plant, improving the uptake of water and nutrients from the soil. Adequate magnesium and sulphur nutrition supports overall plant vitality and balanced metabolic activity.

MacroSpeed® Green helps crops maintain tolerance to abiotic stress, particularly drought and low temperatures, by supporting physiological balance under unfavourable growing conditions. The product has a low acidifying potential, making it suitable for sustainable soil management.

Regular use of MacroSpeed® Green has a positive effect on yield, especially where magnesium or sulphur availability is limiting. It also contributes to improved quality parameters of the marketable yield, including protein content, fat content, starch, sugars, and unsaturated fatty acids, depending on crop type and agronomic conditions.

In addition, magnesium sulphate monohydrate (kieserite) plays a key role in maintaining ionic balance within the plant and acts as an essential activator of numerous enzymes, influencing energy metabolism, protein synthesis, and carbohydrate formation. The sulphur component supports the synthesis of sulphur-containing amino acids, improving protein quality and enhancing nitrogen efficiency.

Thanks to its water-soluble kieserite form, MacroSpeed® Green is particularly well suited for early spring applications and periods of rapid crop growth, when magnesium and sulphur demand is high and soil mineralisation is limited. Its predictable nutrient availability, combined with a low risk of nutrient losses, makes MacroSpeed® Green a reliable solution for precision nutrient management and modern agricultural systems.

Technology in practice

Suitable for pre-sowing and top-dressing applications across all crops, MacroSpeed® Green offers flexible, year-round use in accordance with Good Agricultural Practice on all soil types. It is recommended both where magnesium and/or sulphur deficiencies are identified and where optimisation of nitrogen use efficiency is required.

Thanks to its water-soluble kieserite (magnesium sulphate monohydrate) formulation, MacroSpeed® Green ensures rapid nutrient availability after application, making it particularly effective in early spring and during periods of intensive crop growth. The product performs reliably under cool soil conditions, when nutrient release from organic sources may be limited.

The fertiliser supports uniform nutrient distribution in the root zone, improving nutrient uptake efficiency and ensuring a consistent crop response. Its low acidifying potential allows safe use on both light and heavy soils, including fields managed under sustainable and precision farming systems.

MacroSpeed® Green features a uniform granulation, with 93.8% of granules passing through a 5 mm sieve, ensuring a consistent particle size and even spreading across the field. The bulk density of 950 kg/m³ provides excellent flowability and enables accurate application with standard fertiliser spreaders, supporting uniform field distribution and reducing the risk of segregation during handling.

Thanks to these physical properties, MacroSpeed® Green allows uniform application with spreading widths of up to 36 m, ensuring stable spreading patterns, precise dosing, and even nutrient distribution across the entire working width.

MacroSpeed® Green integrates easily into existing fertilisation programmes and is fully compatible with balanced NPK strategies, helping growers achieve stable yields, improved crop quality, and efficient nutrient management under a wide range of agronomic conditions.
