Description
Primavera 5-7-14 is an organo-mineral npk fertilizer with a high potassium content, particularly recommended in viticulture, especially when aiming for quality productions while supporting good productive loads.
For the same reasons, its use is also recommended for most tree crops. In the context of industrial crops, it is useful during pre-sowing and pre-transplanting phases as it combines an optimal phosphorus-potassium supply with a fractionated and non-leachable nitrogen content, making it compatible even in agricultural contexts at risk of nitrates.
The phosphorus-potassium supply maintains high solubility even in alkaline, cold, or low organic matter soils.
The high presence of sulfur, in synergy with nitrogen, enhances the absorption process of the two elements and plays an important role in improving the quality of productions. Sulfur is indeed required in biochemical processes related to protein synthesis as a constituent of vitamins and enzymes, as well as in the photosynthetic process, providing greater consistency and resistance to plant tissues and improving the organoleptic properties of the final product.
The formulation is finally completed with magnesium, calcium, and iron to allow the crop to achieve maximum efficiency in vegetative-productive metabolism.
Organic carbon has a protective function on mineral components, improving their assimilability by crops.
