Welcome to our home

We are located in Silla (Valencia) and our facilities have a surface area of 55,000m2 designed to meet the agricultural and industrial sector needs. Thanks to our location, we are connected to the main road transport routes and very close to the port of Valencia, through which we provide service to national and international markets. In addition, we have two off-site centres, one logistics centre to serve Andalucía (south of Spain) and another production centre in Castilla y León to serve the North of Spain.

R+D+i Center - Laboratory

Inaugurated in 2020, it is a modern and cutting-edge laboratory.

We have based our growth on the continuous effort to innovate and search for solutions and new products, which is why we have designed the new laboratory. We have state-of-the-art equipment to carry out quality controls and the development and R+D+I of new efficient and sustainable solutions.

In addition, to enhance the analytical capacity we have different cutting-edge chromatography equipment.

Biostimulants plant

Inaugurated in 2016, it has the capacity to produce the different solutions of our wide catalogue, both solid and liquid.

We also have two packaging lines that give us the possibility of packaging liquids in formats ranging from half a litre to 1,000-liter IBCs, so we offer great versatility throughout our range of biostimulants, adapting to the needs required by the end user.

Solid fertilizers plant

We have 2 facilities for the production of blends with inhibitio (TARALENT®), as well as 2 fully automated packaging stations, 3 Big Bag packaging lines (one of which is exclusively dedicated to the Industrial line) and a new plant for the manufacture of crystalline fertilizers. This new facility inaugurated in 2017 has highlighted the three fundamental pillars of the reputation of our KRYSTAFEED® brand: exhaustive quality control of raw materials, process precision to guarantee the declared contents and innovation in packaging.

Safe work

In Tarazona we actively work for safety at all levels. We want to contribute to the improvement of health and the environment and to achieve a safe working environment. That is why we work with raw materials that meet with the European REACH regulation and we are committed to reduce occupational risks by setting ourselves the goal of achieving zero accidents.

REACH encourages the transmission and creation of information of chemical substances and their associated risks and places responsibility on manufacturers, importers and downstream users to manage the risks associated with chemical substances, ensuring that they only manufacture, market or use substances that do not adversely affect human health or the environment.

In addition, we invest in continuous training for our employees, on how to carry out their tasks in order to avoid risks, first aid and to improve the response to emergencies that may arise.
