In vegetable cultivation of cole, leafy and bulb vegetables, nutrient supply via foliar fertilisation with a wide variety of nutrients has become established.
On the one hand, a foliar fertilisation measure offers a quick remedy in case of insufficient nutrient availability or drought.
In weather-related stress situations (e.g. cold and wet, but also drought), the plant can be supported in building up protein and carbohydrates by a direct supply of amino acids. This leads to an increase in metabolism and stimulation of photosynthesis. We recommend the product Aminosol® for this application. A second possibility, which causes stress in young vegetable plants, is transplanting. Amino acids promote root formation. The faster a plant forms new roots after transplanting, the earlier optimal growth can begin. For this purpose, it is recommended to dip the young plants in a 1 % Aminosol® solution or to treat them immediately after transplanting.
Stress can also be caused by plant protection measures (e.g. foliar-active herbicides). The use of Aminosol® has also proven successful in this combination.
Nutrient antagonism or very rapid growth can lead to a deficiency of a certain nutrient, even if its content in the soil is in the optimal range. For example, a high nitrogen and potassium content in the plant often leads to a calcium deficiency, as the two main nutrients block the uptake of calcium. The consequences of a calcium deficiency in cabbage and leafy vegetables are reduced leaf firmness and dry leaf tips on the youngest leaves. With the use of Lebosol®-Calcium-Forte SC, a leaf-friendly, effective supply of calcium takes place without the dangers of leaf burn.
Elements such as boron and zinc play an important role in improving the quality of vegetables. Both elements promote the absorption and relocation of calcium. This in turn is essential for good storage and transport quality of the vegetables. For this purpose, Lebosol®-Robustus SC (boron + calcium) and Lebosol®-Zinc 700 SC can be applied several times during the season.
When cultivating cabbage and leafy vegetables, chlorotic lightening and leaf spots are undesirable. To bring the plants back to the required leaf quality, foliar fertilisation with macro- and micronutrients offers quick help. A complex plant analysis provides quick information about which nutrients are deficient. Based on this, targeted foliar fertilisation is possible, which always has a positive influence on yield and quality.
