Foliar products can be used preventive as integrated part of the fertilizer strategy or in case of identified and/or visual deficiencies as curative solution.
The leaf analysis has proven to be a useful tool for detecting latent nutrient deficiencies.

In the soil environment many factors can limit the availability of nutrients – high pH-values can block micro-nutrients, low pH-values can block macro-nutrients.
The apple has more requirements than the pear in the area of plant nutrition. In apples, elements such as nitrogen (to achieve a high yield), potassium and phosphorus (for optimal colouring with good fruit quality), the creation of a favourable potassium-calcium ratio for firm fruits and a balanced supply of magnesium and manganese to prevent leaf spots play an important role. The pear, on the other hand, is more susceptible to iron chlorosis.
Some varieties, especially Golden Delicious, Jonagold, Elstar, Gala and Cox are prone to nutritionally induced leaf necrosis and premature leaf drop. The causes for this are, among others, an undersupply of manganese and magnesium. The combination of Lebosol®-Magnesium 400 SC with Lebosol®-Manganese 500 SC alleviates the symptoms and reduces premature leaf drop.
Boron in combination with calcium (Lebosol®-Robustus SC), zinc (Lebosol®-Zinc 700 SC) and amino acids (Aminosol®) has a positive influence on pollen tube growth, flowering, fruit set and reduce of russeting. They can be co-applied before flowering or after harvest. The application of Lebosol®-Robustus SC before flowering improves apple colouring. Boron and zinc also promote calcium absorption.
Phosphorus and potassium have a positive effect on the colouring of the fruit, so that the red overcolour is promoted with several leaf applications from fruit set with Lebosol®-PK-Max. At the same time, phosphorus contributes to better fruit firmness and less flesh browning.
Pears in particular are prone to iron chlorosis. Iron deficiency is manifested by yellowing of the youngest leaves with dark leaf veins. Early and regular foliar fertilisation with Lebosol®-HeptaIron is a remedy. Lebosol®-HeptaIron is a particularly effective iron leaf fertiliser that can also be used in organic cultivation.
