Crops balanced nutrition is fundamental to achieve high yields.

Plant nutrition is based on the three macro-elements, i.e. Nitrogen, Phosphorus and Potassium, which are the nutrients most required by plants, and consequently need constant contribution during the cultivation. In addition to macro-nutrients, cultivated plants need meso-elements, i.e. Calcium, Magnesium, Sulphur and Silicon, as well as micro-elements, which are required by plants for specific metabolic processes and activities. Meso- and micro-nutrients are as fundamental as macro-elements to obtain the best qualitative and quantitative crops yield, due to their part in fruits aroma, color and taste formation. The insufficient availability of these nutrients, due to weather conditions, use of the nutrients by previous crops and the lack of them in the standard fertilizers, mainly containing macro-elements, leads to the need of integrating in plants diet, either to cure or prevent any physiological disorder caused by their absence.

Green Ravenna wide range of nutrients, containing different meso- and micro-elements at different concentrations, either for roots or foliar applications, allows to set up different fertilization programs, specific for each crop, phenological stage and production target (i.e. vegetation growth, Brix grade increase, fruits swelling, correct nutrients-deficiency, etc.)
