In vegetable cultivation of fruit, root and tuber vegetables, but also of cabbage, leaf and onion vegetables, nutrient supply via foliar fertilisation with a wide variety of nutrients has become established.
On the one hand, foliar fertilisation offers a quick remedy in cases of insufficient nutrient availability, such as high soil pH or drought. On the other hand, such an application via the leaf makes it possible to achieve that "certain extra".
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 as well as to a stimulation of photosynthetic performance. 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 and plant growth. 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 an Aminosol® solution or to treat them immediately after transplanting.
Stress is not only dependent on weather conditions but can also be caused by plant protection measures (e.g. foliar-active herbicides). The use of Aminosol® has also proven effective in this combination.
The so-called nutrient antagonism 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 fruit often leads to a pronounced calcium deficiency, as the two main nutrients block the absorption of calcium. The consequences of a calcium deficiency in fruit vegetables are reduced fruit firmness, blossom end rot, burnt leaf tips and curled leaves. With the use of Lebosol®-Calcium-Forte SC, a leaf-friendly, effective supply of calcium takes place without the dangers of leaf burns, which are caused, for example, by calcium formulations containing salt.
For a quick remedy of potassium deficiency, a liquid potassium fertilisation over the leaf with Lebosol®-Potassium 450 is recommended. A good potassium supply can increase the stability in storage and the quality of the skin, so that an improved shelf life can be expected. In tomatoes and peppers, potassium additionally improves the colouring.
To improve fruit set in vegetables, elements such as boron and zinc play an important role. For this purpose, Lebosol®-Robustus SC (boron + calcium) and Lebosol®-Zinc 700 SC can be applied before flowering.
Especially in the cultivation of leafy vegetables, chlorotic brightening, leaf spots or even limp plants with light yellow stripes and brown spots are undesirable. To bring the plants back to the desired leaf quality, foliar fertilisation with micronutrients offers quick help. A plant analysis provides a quick indication of which nutrients are deficient. Based on this, targeted foliar fertilisation is possible, which always has a positive influence on the yield.
