Foliar fertilization in fruit vegetables

In the vegetable cultivation of fruit-, root- and tuber vegetables, but also cabbage, leaf- and bulb vegetables the foliar fertilization for the nutrient care with all kind of nutrients has established itself.
On the one hand, a foliar fertilization measure offers a fast remedy  in case of a bad  nutrient availability, for example with a high pH value in the soil  or aridity. On the other hand such a foliar application enables to cause an”Extra”.


Promotion of growth of vegetable cultures with stress

In weather-related stress-situations (e.g. cold and wet, but also aridity) the plant can be suppor-ted with the construction of protein and carbohydrates by a direct supply of amino acids. This leads to the rise of the metabolism as well as to the stimulation of the photosynthesis perfor-mance. For this main application we recommend the product Aminosol®. The second possibility which causes stress in young vegetable plants is transplanting. Amino acids promote the root formation and the plants growth. The faster a plant forms new roots after planting, the earlier an optimal growth can begin. Moreover it is advisable to dip the seedlings in an Aminosol® solution or to treat immediately after transplanting.

Stress depends not only on weather but can be caused as well by plant protection measures (e.g., leaf-active herbicides).  The application of Aminosol® has proved itself also in this combination.

A special form of the stress reduction in the area of plant protection measures represents the combination of soil herbicides with Herbosol®. Herbosol® was developed specially for this application.

Blossom end deterioration of fruit vegetables caused by calcium lack

By the so-called nutrient antagonism it can come to a lack of a certain nutrient, even if its content is optimal in the soil. So a e.g. high nitrogen and potassium content leads frequently to a distinct calcium lack in the fruit, because these main nutrients block the admission of calcium. The consequences of a calcium lack in fruit vegetables are a decreased fruit firmness, a blossom end deterioration, burned leaf tops and rolled up leaves. With the application of Lebosol®-Calcium-Forte SC a leaf-careful, effective supply of calcium takes place without dangers of leaves-combustions, which are caused e.g. by salty calcium formulations.

Good potassium care as a preparation for durability and storage stability

To the fast recovery of potassium lack a fluid potassium foliar fertilization with Lebosol® potassium 450 is recommended. A good potassium care can raise the storage stability and the quality of the skin, so that an improved durability is to be expected. With tomatoes and paprika potassium improves, in addition, the coloration.

Blossom, fruit setting, yield stabilization

For the improvement of the fruit setting  of the vegetables elements like boron and zinc play an important role.  In addition Lebosol®-Robustus SC (boron + calcium) and Lebosol® zinc 700 SC can be applied before the blossom.

Vitality and resistance with potassium phosphonate

The promotion of plants’own antibodies plays a crucial role in the vegetable cultivation. A treatment with potassium or magnesium phosphite strengthens the resistance as well as the vitality of  different kinds of vegetables  and it has already established itself since some years in practice.  The treatment is combined ideally with fungicide measures. Several applications of Lebosol®-Kalium-Plus or Lebosol®-Magnesium-Plus support the plants’ own resistance  and keep leaf quality and -health.

Promote leaf quality and leaf health by trace nutrient fertilization

Particularly in the cultivation of leaf vegetables chlorotic clarifications, leaf spots or also slack plants with light yellow stripes and brown points are not wanted. To bring the plants back to the wished leaf quality, the foliar  fertilization with micronutrients offers fast help. A plants analysis gives a fast explanation about the fact which nutrients are not sufficiently available. On this basis an aimed foliar fertilization is possible which always has a positive influence on the yield.
