Welcome to our home

We are located in Silla (Valencia) and our facilities have an area of 55.000m2 designed to meet the needs of the agricultural and industrial sector. Thanks to our location, we are connected to the main land transportation routes and very close to the seaport of Valencia, through which we serve national and international markets. In addition, we have two offshore centers, a logistics center to serve Andalusia and a production center in Castilla y León to serve the north of Spain.

R+D+i Center - Laboratory

Inaugurated in 2020, being a modern and reference laboratory.

We have based our growth on the continuous effort to innovate and search for solutions and new products, for which the design of the new laboratory has been carried out. We have state-of-the-art equipment for quality control and the development and R&D of new efficient and sustainable solutions.

In addition, to enhance the analytical capacity we have different state-of-the-art ion chromatography equipment.

Biostimulant plant

Inaugurated in 2016, it has the capacity to produce the different solutions from our extensive portfolio, both solid and liquid.

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

Solid fertilizer plant

We have 2 facilities for the production of blends with inhibition (TARALENT®), as well as 2 fully automated packaging stations, three Big Bag packaging lines and a new plant for the production 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, precision in the process to guarantee the declared contents, and innovation in packaging.

Safe work

At Tarazona Agrosolutions 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 comply with the European REACH regulation and we are committed to reducing occupational risks by setting ourselves the goal of achieving zero accidents.

REACH promotes the transmission and creation of information on 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 perform their tasks to avoid risks, first aid and to improve the response to emergencies that may arise.

Our quality, environmental and occupational risk prevention policies, as well as our equality policy, are at your disposal.
