Agrostock has been growing and evolving within the agricultural sector for 80 years. Currently, it is one of the leading companies specializing in plant nutrition, research, development, manufacturing, and marketing of fertilizers, soil amendments, and biostimulants, with a presence in more than 30 countries.

Agrostock was founded in Fraga in 1945 as a family business, taking over the activities of the Casas Nicolas brothers' company, which dealt in the buying and selling of fruit and plant protection products. In 1956, it established a business relationship with the German chemical and pharmaceutical company Bayer and expanded its operations to include various sectors of agriculture. In 1988, it became a public limited company (SA), its current legal structure, and began a period of exponential growth linked to research and development. Today, it leads the plant nutrition sector with innovative solutions that it exports to Central America, South America, Asia, Europe, and Africa.

This company's plant in Fraga boasts a multidisciplinary team of biologists, chemists, and agricultural engineers . Its 12.000 m² facilities are designed according to a strategic plan that optimizes the quality of production, storage, and distribution of its formulations. They have a production capacity of 150.000 tons and a liquid product storage capacity of 4.500 tons. In addition, Agrostock also has 30 hectares of experimental fields, enabling them to research and develop all kinds of solutions to improve crop quality, health, and profitability.

Efficient and responsible agriculture with the production of our own nanoparticles
