Cabbages, leafy vegetables and bulb vegetables

Foliar fertilization of cabbage, leaf vegetables and bulbous vegetables

In the vegetable cultivation of fruit-, root- and tuber vegetables, but also of cabbage, leaf- and bulbous vegetables the nutrient care via foliar fertilization with most different nutrients has established itself.

On the one hand, a foliar fertilization application offers in case of insufficient nutrient availability as for example a high pH value in the soil or in case of aridity a fast remedy. On the other hand  such a foliar application enables to cause an “extra”.

 

Growth promotion of vegetable cultures with stress

In weather-related stress situations (e.g. cold and wet, but also aridity) the plant formation of protein and carbohydrates can be supported by a direct supply with amino acids. This leads to an increase of the metabolism efficiency as well as a stimulation of the photosynthesis efficiency. We recommend the use of Aminosol® for this main application. 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 putting, 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). Also in this combination the application of Aminosol® has proved itself.

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

Blossom end deterioration by calcium deficiency of fruit vegetables

By the so-called nutrient antagonism it can come to a deficiency of a certain nutrient, even if the soil content is in an optimal range. So a e.g. high nitrogen and potassium content leads frequently to a distinct calcium deficiency in the plant, because both main nutrients block the admission of calcium. The consequences of a calcium deficiency in fruit vegetable are a decreased fruit firmness, a blossom end deterioration and 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 leaf combustions, which are caused e.g. by salty calcium formulations.

Good potassium care as a preparation for durability and storage stability

For fast recovery of potassium deficiency a fluid potassium fertilization via leaf with Lebosol®-Kalium 450 is recommended. A good potassium supply can raise the storage stability and the quality of the peel, so that an improved durability is to be expected.

Blossom, fruit setting, yield stabilization

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

Vitality and resistance by potassium phosphonate

The promotion of plant’s own antibodies plays a decisive role in the vegetable cultivation. A treatment with potassium or magnesium phosphonate strengthens the resistance as well as the vitality of the most different vegetable varieties and 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 plant’s defences and preserve the leaf quality and -health.

Promotion of leaf quality and -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 to the wished leaf quality, the foliar fertilization with micronutrients offers fast help. A plants analysis gives a fast information about which nutrient deficiency occurs. Thereafter an aimed foliar fertilization is possible, which affects the yield always positively.
