Grena Plus 4-1-1

Its composition offers a gradual release of the elements with a constant mineralisation over time and does not bring excessive salinity to the soil. Rich in humic and fulvic acids, GRENA PLUS fertilizer stimulates the formation of highly available and stable complexes facilitating the passage of nutrients from the soil to the roots. The naturally present calcium in the product increases the resistance of plant tissues, as well as the increase of freshness and conservation of crops, especially in the presence of problematic environmental conditions (high temperatures, drought, etc.).
