Advantages products

We develop biostimulants and fertilisers that help growers cultivate stronger, healthier, and more resilient crops. Our products are based on natural ingredients, are scientifically validated and have undergone extensive testing under real-world conditions. Whether you work in organic or conventional cultivation, grow under glass or in open fields, our solutions help achieve vigorous crops and higher yields, without leaving any residues.

On this page you will learn more about the properties, uses, and benefits of our products.

Why choose PlantoSys biostimulants and fertilisers?

Natural, safe and user-friendly

Our products are entirely of natural origin. We use only ingredients that support the plant without negatively impacting the crop, environment, or the user. They leave no residues, do not inhibit growth, and have no re-entry restrictions and no harvest waiting periods. This makes our products practical to use and saves time during the cultivation process.

Suitable for both conventional and organic crops

Our biostimulants and fertilisers are highly versatile, suitable for both conventional and organic farming. We are happy to inform you which products are permitted in your country.

CE fertilisers and CE biostimulants

Within our range, we distinguish between fertilisers and biostimulants. Fertilisers provide essential nutrients to the plant, while biostimulants enhance the plant’s natural processes, including growth, resilience to abiotic stress, and more efficient nutrient uptake.

Our fertilisers comply with the European Fertilising Products Regulation (EU) 2019/1009 and are CE marked.

SalicylPure and SilicaPower also have CE marking as biostimulants. CE marking requires strict verification of effectiveness and raw material origin. Only products that have undergone independent testing and are proven to meet these criteria may be marketed as CE biostimulants. More information about their effects, benefits and the certification process can be found on our biostimulants page.

Flexible solutions for targeted crop application

Our products are versatile in use and can be used either separately or in combination. Depending on the growth stage and the desired outcome, Argentum, Cuprum, SalicylPure and SilicaPower can be used separately.

Some ingredients work synergistically, prompting the development of ready-to-use combinations, such as ArgicinPlus, MicroPower and Nutricin. These formulations offer added convenience and ensure consistent, effective application when used in cultivation.

Seven powerful natural ingredients for strong and resilient plants

In our formulations, we consciously include a selection of ingredients, each contributing uniquely to plant vitality and resilience. Below, we highlight seven key substances that can be applied separately or in combination, depending on crop needs:

  • Willow bark extract – Strengthens the plant’s own defence mechanisms.
  • Colloidal silver – Supports internal processes (photosynthesis) and helps the plant remain balanced under changing conditions (leaf temperature regulation).
  • Micro-copper – An essential trace element for various plant processes and overall vitality.
  • Silicon (orthosilicic acid) – Strengthens cell walls and the epidermis. Helps plants to absorb their water and nutrients more efficiently.
  • Micro-manganese and micro-zinc – Improve plant resilience and ensure robust crops.
  • Amino acids – Readily absorbable building blocks (N) that support the plant during growth and recovery.

These ingredients contribute to crops that are stronger, more vigorous, and more resilient. The stable formulation ensures that the metal particles in colloidal silver, micro-copper, micro-manganese and micro-zinc do not agglomerate in solution. They retain their effectiveness for at least two years and adhere to the leaf surface like a ‘magnet’, providing a long-lasting strengthening effect and preventing leaching by rain.

Effective growth and natural strength – the power of our biostimulants and fertilisers

We continuously learn and improve through in-house testing, the practical experiences of growers, and feedback from distributors. By continually investing in independent research, we develop increasingly effective products that consistently meet the needs of cultivation practices.
