Know How

Foliar Fertilizers offer:

  • Rapid nutrient supply
  • High nutrient efficiency
  • Reduced soil pollution
  • Improvement of spray mixture features

Foliar Fertilization is recommended when:

  • Nutrient absorption is inadequate or uncertain from the soil
  • Nutrient demand of the plant is higher than nutrient supply by the soil-root system, especially during critical stages
  • Nutrient distribution within the plant is limited
  • Nutrient deficiencies are already visible

Protect your yield

Nowadays extreme weather conditions more and more represent extreme stress conditions for crops. WUXAL® supports your crops in the best way!

High quality and well-balanced WUXAL® Foliar Fertilizers provide your crops individually with all required nutrients and enhance their ability to pass critical stages. Well-nourished plants will be able to ensure high yield levels, even under difficult conditions.

As yield and quality may be restricted by the lack of one single nutrient, it is important to support your crops with a well balanced nutrient range.

Nutrient Deficiency

Foliar nutrition is a multifunctional recovery tool. It is the right choice when deficiency symptomes are noted. Due to the fast nutrient uptake, rapid correction of nutrient deficiencies is possible.

Foliar Absorption
and Transport Mechanisms

Before being assimilated, a nutrient must be absorbed by the leaf or fruit tissue. Fundamental steps of foliar nutrient absorption are as follows:

  • Penetration through the cuticle. The cuticle is the first
    and most limiting barrier to foliar nutrient uptake.
  • Penetration through the epidermal cell wall.
  • Nutrient uptake into the cells.
  • Distribution inside the plant as a function of nutrient mobility.

Efficient absorption depends on good wetting of the leaf surface, on the pH of the spray solution and on many other parameters. The quality and the nutrient ratio of the formulation will determine absorption efficacy and agronomic performance. WUXAL® Foliar Fertilizers are equipped with special additives favoring excellent wetting, rain fastness and penetration of the nutrients involved. WUXAL® products are formulated in such a way that they remain well compatible with most pesticides' active ingredients.

Development

Agriculture in the 21st century faces multiple challenges: it has to produce more food and fibre to feed a growing population with a smaller rural labour force, more feedstocks for a potentially huge bioenergy market, contribute to overall development in the many agriculture-dependent developing countries, adopt more efficient and sustainable production methods and adapt to climate change.
WUXAL® applications and the development of new perfectly adapted formulas are an integral part of it.
Our own development department is the key to sustainable and highly efficient formulations, perfectly adjusted to the crop’s requirements and your special needs.

  • highest utility, efficacy and quality
  • outstanding product handling
  • second to none shelf life

Analytics

In the completely new laboratories the staff focuses on permanent quality control accompanying the day to day production process for state-of-the-art WUXAL® products.

  • nutrient analysis
  • heavy metal analysis
  • pH and density check
  • rheological measurements
  • compatibility tests

The new lab is equipped with up-to-date analytical instruments, such as ICP-OES facilities, high-end capabilities for rheological measurements and Kjeldahl N-analytics. Therefore, highest quality standards can be guaranteed.
