Why choose Ferti foliar fertilizers?

Foliar nutrition of plants has become an integral part of modern crop cultivation, since it enables to develop the fullest potential of plants. According to Liebig’s Law of the Minimum the deficiencies of trace elements in the soil limit the absorption of other available nutrients from the soil.

Low temperatures and drought hamper the absorption of major macronutrients of the soil and the nutrients received through the leaves of the plant absorbed immediately. That is why the effectiveness of such feeding is much higher compared to the root. Not only can fast shortfall nutrients restore the balance, but it also can significantly increase the ability to absorb nitrogen, phosphorus and potassium from the soil. Providing plants with essential nutrients in important phases of development improves productivity and quality of the resulting product (studies confirm elevation of gluten in wheat and sugar beet after the application of our fertilizers).

What makes fertilizer “FERTI” special?

k-05EDTA chelation:

prevents the precipitation of nutrients contained in the product
improves uptake of nutrients
regulates pH of spray solution

k-02Humectants (wetting agents):

re-activate dried fertilizer on the leaf surface
prolong absorption and improve uptake of nutrients

k-06Ideal composition of macro and micronutrients:

Fully provides plant nutrients
Increases resistance and resistance to negative factors Environment- drought, flooding, temperature changes
Accelerates growth and crop quality


prevent evaporation of fertilizer microdroplets before reaching leaf surface
prolong hydration of drops
improve absorption of nutrients
increase application efficiency

k-04Surfactants (surface active agents):

ensure an even distribution of the fertilizer on the leaves
provide more detailed coverage of the leaf surface
improve compatibility with crop protection products

k-03Adhesion agents:

prevent fertilizer from washed off during heavy dew or rain
minimize fertilizer losses
increase effectiveness of foliar nutrition

The chemical purity and quality of raw materials  

Since the absorption of nutrients in foliar feeding takes place through such a sensitive organ as the leaves of plants, fertilizers must meet the highest quality standards. The quality of the finished product depends on the raw materials which were used for the production of fertilizers. The content of undesirable elements, such as heavy metals or other toxic substances (e.g., biuret urea) adversely affects the digestibility of leaf fertilizers. Fertilizers “Ana” are made from raw materials that are constantly tested for their quality. For the production of fertilizer German concentrate produced by «Profert Technology GmbH» is used. Furthermore, the fertilizer includes patented anti-evaporators and surfactants, as well as substances which increase the wettability and adhesion (adhesion to the surface).

Buffering properties of the foliar/ leaf fertilizer

One of the most important features of sheet fertilizers are buffering properties, ie the ability to regulate and maintain the desired acidity of the working solution, regardless of the pH of the water used. The use of the recommended (and as practice shows, even smaller) amount of fertilizer effectively brings the water to a neutral pH.

Chelation of microelements

Modern leaf fertilizer must first provide a full range of plant micronutrients, that is why it is important to trace that microelements do not precipitate either in the box or in the final working solution. Salts often cannot provide high quality fertilizer because micronutrients (especially copper, iron, manganese and zinc) are metal ions having a positive charge and readily undergo unwanted chemical reactions. The consequence of these processes is the deposition of a large amount of insoluble precipitate, and a substantial reduction in quality of the fertilizer. Therefore, the best form of security of plant trace elements are chelated – compounds with organic chelated trace elements. The main advantage is their high digestibility and rapid movement within the plant.

For foliar fertilizer production different chelating agents such as tartaric acid, acetic acid, citric acid or amino acid are used. Their main advantage is the low price and ease of use in the production of leaf fertilizer, but the effectiveness of these substances is different. Using these acids requires, in most cases, the oxidation of the fertilizer to a pH of 3-4, because only strong oxidation provides stability of the solution. However, so sour fertilizer may have a negative impact on plants. Furthermore, this method does not provide long-term chelation result, since in the final working solution it increases the pH level and provides no protection from microcells precipitation. That is why for the production of fertilizers “FERTI” we use only high-quality and effective free chelate formation agent – EDTA.

Fertilizers “FERTI” are very few fertilizers 100% chelated by free chelate formation agent – EDTA. An additional guarantee of quality is the presence of additional free acid EDTA which provides the stability of trace elements in the preparation of working solutions. This so-called “super chelate” formation ensures complex calcium, magnesium and iron compounds contained in water used for spraying. As a result, the plant assimilates these additional substances, and the water hardness is reduced. The unique composition of the fertilizer allows you to mix it with pesticides, thereby significantly increases the economic efficiency of the use of leaf fertilizers.
