About us

Experts in agricultural foliar fertilizers.

The owner, Adam Sisik, has 20 years of experience in the formulation of fertilizers and pesticides and, together with experts in the field of process technology and chemistry, successfully adds new products to the company’s offer. We currently employ 40 people, and the production plant is located in Tarczyn – 30 km from Warsaw. We mainly produce liquid and suspension fertilizers. Our products can be used in fertigation and foliar application.

Unlike competitors’ products, each of our fertilizers contains a full range of adjuvants and additionally Epibrassinolide, a plant steroid that stimulates immunity during adverse conditions (atmospheric or disease) – which translates into the efficiency of using our products. We also offer an innovative suspension formulation, which can be a great advantage in the competitive market, and we value good personal relationships and flexibility in everyday work.


The company ended 2022 year with a production volume exceeding 5,000,000L, for 15 countries around the world. We are in most European Union countries as well as in Kazakhstan, Indonesia, Oman, Taiwan, China, Vietnam.

In the near future, the company is planning a major expansion of the laboratory for the purpose of quality control and analysis of raw materials, as well as an investment in a mixing line for crystal carts. However, our flagship project will be the launch of four biological products – based on beneficial fungi and bacteria.

With the development of the company we are looking for business partners all over the world who are interested in revolutionary solutions of plants fertilizing.
