Optimum nutrient supply for citrus fruits
Efficient foliar fertilisation for healthy citrus plants
Foliar fertilisation has been an indispensable part of the nutrient supply in citrus cultivation for many years. It is used both for visible deficiencies such as manganese, iron or magnesium deficiencies and for latent deficiencies. This method ensures an efficient supply of liquid fertilisers to the plants, which are absorbed quickly and directly through the leaves.
Even with optimum soil fertilisation, it is not always possible to ensure that citrus trees are supplied with the necessary nutrients in terms of main, secondary and trace elements. Factors such as high or low pH values, drought, cool weather, soil compaction and competition from greenery can significantly impair the absorption of nutrients from the soil. Foliar fertilisers offer an effective solution to overcome these challenges and ensure plant health.
Improvement in flower quality and fruit set
Targeted fertilisation of citrus fruits
Boron in combination with calcium (Lebosol®-Robustus SC), zinc (Lebosol®-Zinc 700 SC) and amino acids (Aminosol®) has a positive effect on flower quality, pollen tube growth and fruit set. This combination of nutrients can be applied both before flowering and after the harvest to ensure an optimum supply. The application of boron and zinc also promotes calcium uptake, which leads to improved fruit development and higher yield quality.
Control of leaf spot and premature leaf fall
Effective nutrient solutions for healthy leaves
Some citrus varieties are prone to nutritional-physiological leaf necrosis and premature leaf fall caused by an undersupply of manganese and magnesium. The combination of Lebosol®-Magnesium 400 SC with Lebosol®-Manganese 500 SC alleviates these symptoms and effectively reduces premature leaf fall.
Molybdenum deficiency, known as ‘yellow spot’, is characterised by glassy, roundish to oval spots between the leaf veins, which later take on a golden yellow colour. If the deficiency is severe, the necrosis spreads to the leaf edge, which curls. Early and regular foliar fertilisation with Lebosol®-Molybdenum prevents the formation.
Combating iron chlorosis in citrus fruits
Effective solutions through targeted foliar fertilisation for lemons, oranges and co.
Iron chlorosis is a common deficiency symptom in citrus fruits, which is characterised by yellowing of the youngest leaves and dark veins. Early and regular foliar fertilisation with Lebosol® HeptaIron can effectively counteract this iron deficiency. The targeted use of this special liquid fertiliser optimises the iron supply to the plants, resulting in resistant citrus trees.
Improved fruit quality and shelf life
How do you optimise the nutrient balance and firmness of citrus fruits?
The potassium-calcium ratio is crucial for improved fruit firmness. An oversupply of potassium can inhibit calcium uptake, which leads to a calcium deficiency. Despite good calcium availability in the soil, this does not always guarantee an adequate supply to the fruit due to the special calcium transport in the plant. Repeated calcium spraying with Lebosol®-Calcium Forte SC, a particularly well-tolerated calcium source, is necessary. This product also provides an additional supply of manganese and zinc.
