Continued use of GRENA MEDIO increases water retention capacity and nutrient assimilation in loose soils, while in heavy soils it improves soil structure and provides greater resistance to compaction, as well as effective soil aeration and good drainage.
The presence of Magnesium stimulates chlorophyll production, which underpins photosynthesis, promoting intense colouring of leaves and fruit and increasing productivity.
The Calcium present strengthens the cell membrane and plant tissues.
GRENA MEDIO is recommended for maintaining soil fertility.
