Foliar fertilization in cabbage, leaf and onion vegetables

The foliar fertilization in vegetables as cabbage, leaf and onion vegetables, is well established in the professional production since many years.

The foliar fertilization in vegetables as cabbage, leaf and onion vegetables, is well established in the professional production since many years. One advantage of foliar fertilization is the fast availability and effectiviness of the nutrients especially if nutrients are not sufficient available in the soil (blocked by pH-value or weather conditions).

 

Stimulating growth under stress conditions

In weather-related stress-situations (e.g. cold, wet, dry) plants are suffering but can be supported with a direct application of amino acids with the product Aminosol®. Aminosol®  will stimulate the formation of protein and carbohydrates through a direct supply with amino acids. This leads to an improved metabolism and photosynthesis efficiency.

But also replanting can cause stress for young vegetable plants. Seedlings can be diped directly in an Aminosol® solution for better and faster root growth.

The application of herbicides can cause physiological plant stress as well. Aminosol® will help the plant to overcome stress after herbicide application and to metabolise herbicide active substances.

If it comes to the application with soil herbicides, we recommend the combination with our adjuvant Herbosol®. Herbosol will improve the stability and reliability of the herbicide without washing out (heavy rain) and shifting of active incrediants into the soil.

End of flowering blight through calcium deficiency

Calcium deficiency will cause reduced fruit stability, end of flowering blight, burned leaf edges and rolled up leaves. The foliar fertilizer and salt-free formulation Lebosol®-Calcium-Forte SC will help to optimize the calcium nutrition without any crop damages. These calcium deficiencies can occur if nitrogen and potassium are oversupplied (nutrient antagonism) and blocking the uptake with calcium.

Potassium are essential for shelf life and storage stability

An optimized nutrition with potassium (Lebosol®-Kalium 450) can improve the shelf life and storage stability of vegetables.

Flowering, fruit setting & yield

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.

Resistance and vitality

The application with phosphonates – Lebosol®-Kalium-Plus or Lebosol®-Magnesium-Plus  in combination with contact fungicides can help to keep plants healthy and strengthen the vitality. The plants are more robust and less susceptible for diseases. Several treatments with Lebosol®-Kalium-Plus or Lebosol®-Magnesium-Plus will enhance plants health and quality.

Micro-nutrients for stimulating leaf health and quality

Foliar fertilizer with micronutrients can enhance plants health and can avoid chlorosis, leaf spots and other critical symptoms related to quality.  A complete plant analysis can help to evaluate the level of nutrient supply, to optimize fertilization for high yield and quality.
