Opis

CalMag Alga is a completely natural soil improver with a high content of calcium, magnesium, vitamins, minerals, and trace elements. It ensures fast uptake of calcium and magnesium, enabling optimal plant growth. In addition, it regulates soil pH to a range of 5.5 to 6.5, increases microbial activity, improves nutrient retention, promotes soil life, and strengthens plant cell walls. Yields become higher and of better quality, while plants grow more resistant to pests, fungi, and pathogens.

Why Choose CalMag Alga – Organic Calcium and Magnesium

Higher-quality flowers, fruits, and increased yield

Calcium contributes to firmer fruits and longer shelf life, while magnesium promotes growth and energy. Together, they increase the number of flowers and fruits, as well as the final yield. CalMag Alga also helps prevent fruit rot.

Dark green leaves – improved photosynthesis

Magnesium is a key component of chlorophyll. With the addition of CalMag Alga, plants develop a more intense green leaf color, grow faster, and produce more energy.

Improved nutrient uptake

Calcium improves root function and enables more efficient uptake of nutrients and water from the soil. Plants are able to make better use of all fertilizers and organic supplements they receive.

tronger cell walls – more resilient plants

CalMag Alga contains an optimal ratio of calcium and magnesium that strengthens cell walls and helps plants develop a firm and stable structure. Plants become more resistant to stress, heat, diseases, and breakage.
