For optimal yields, each plant requires specific nutrients. The KALI-TOOLBOX app gives you immediate clarity about the type of deficiency and its treatment. It also suggests suitable products and connects you with our experts.
Benefits of the KALI-TOOLBOX app
Identifying nutrient deficiencies in the field
Identify nutrient deficiencies right in the field. The new KALI-TOOLBOX app's augmented reality function makes this possible. The app can display 3D models of typical deficiency symptoms on your smartphone.
Each plant has specific nutrient requirements. Ideally, soil fertilization should cover all requirements depending on the yield. If there are too few nutrients, or if nutrient uptake is insufficient during dry periods, deficiency symptoms will develop. It is important to recognize these symptoms and remedy the deficiency immediately with foliar fertilization. Our app provides support in doing just that, offering numerous photos and 3D models of typical deficiency symptoms.
Insights in the KALI-TOOLBOX app:

Which nutrient deficiency appears first on older leaves and which appears first on younger ones? What are the typical symptoms? You can find the answers to these questions and more in the KALI-TOOLBOX.

Choose your crop and compare its symptoms with the 3D models or photos to determine which nutrient is missing.

Additionally, the description of typical symptoms provides valuable information. To address the deficiency, we offer advice on remediation.
Calculate fertilizer quantities
Conveniently calculate nutrient removal and fertilizer quantities in just a few steps, and keep track of everything with information on different nutrient forms!
The Liebig nutrient calculators help you determine the optimal amount of fertilizer to use. The calculations include nutrient removal depending on the crop and yield, soil content, and organic fertilization. You can use the calculators for soil and foliar fertilization.
The nutrient converter helps you keep track of information in different nutrient forms. With just one click, you can convert the content of fertilizers—for example, from K₂O to K or from MgO to Mg.
Find the right fertilizers

The KALI-TOOLBOX app tells you which nutrients your plants need and how much of each nutrient they need. Now, all you need is the right product. You can find information about that in the app, too.
