GRENA EXTRA CORNUNGHIA contains 15% horn shavings and is ideal for climates with both high temperatures and high humidity, for example in greenhouse crops or particularly sun-exposed areas where the mineralisation of organic matter is accelerated.
The horn shavings blended into the source extend the release of nutrients over time, keeping the product slow-release and improving soil structure.
Using GRENA EXTRA CORNUNGHIA on aromatic herbs enhances the colour and scent of the leaves; in basil, it boosts beneficial qualities by increasing the presence of vitamins, flavonoids and antioxidants. An immediate effect visible in thyme is a shift in colour to a brighter green with a more intense scent. Using GRENA EXTRA CORNUNGHIA on open-field strawberry crops allows for a longer production period with firm, crisp fruit and a longer shelf life.
