The leaf analysis for all macro and micro elements will help to analyse and understand the level of supply for each nutrient and to avoid from the beginning some latent deficiencies.

Many parameters in the soil can limit the availability of nutrients – high pH-values can block micro-nutrients, low pH-values can block macro-nutrients. But also dry and cold weather conditions, soil texture and some nutrient antagonism (e.g. oversupply with potassium vs. magnesium and calcium) can lead to a deficiency of nutrients.
The application of Aminosol® before flowering will enhance fruit setting and fruit growth because of the combination of amino acids and the auxin effect. In addition, a sufficient supply with boron will be necessary for fruit growth and stability. For best and high yield, the combination of Aminosol® and Lebosol®-Robustus SC (boron + calcium) should be applied before flowering.
Wine grapes are susceptible to iron chloroses. Most frequently it’s not a real deficiency, but rather a limited uptake of nutrients. An iron deficiency will be visible by yellowness of the youngest leaves with dark veins. Different parameters, e.g. soil structure, moisture and pH value will influence the iron availability.
Lebosol®-Magnesium 400 SC will help to prevent magnesium deficiency and ca be applied few times on the leaves. Magnesium deficiency symptoms are yellow and brown leaves. If the K vs. Mg nutrition is not balanced, susceptibility for stark paralysis is increased with the result of slowed maturity, decreased yield and quantity.
Calcium is essential for the cell wall and thereby the stability of the fruits. Lebosol®-Calcium-Forte SC, free of chloride, will improve the calcium concentration in the fruit and enhance quality and shelf life.
Potassium is stimulating the sugar formation/contentand will enhance fruit maturity and frost hardiness. A significant deficiency of potassium will cause drying and destroying of leaves during the summer and a reduction of winter hardiness. The quality of fruits will suffer as well. The application with Lebosol®-Potassium 450 will optimize the K2O nutrition for the best quality of grapes.
Phytoamin®- a cold pressed seaweed formulation will enhance the resistance against diseases and make grapes more robust and stronger. This will also have a positive impact on the assimilation and the grape and wine quality.
