SIDDRA: diagnosis and tips for the nutrition of your crops

The Siddra system is a software created by Fertiberia for the diagnosis, interpretation and recommendation of the analyses managed from its Agronomic Laboratory.

At Fertiberia, aware of our responsibility as a leading company in the plant nutrition sector, we encourage a rational and appropriate use of our products. This is why the Siddra system was created, to further optimise the interpretations, the diagnosis and the fertiliser recommendations that have complemented your agricultural analyses for more than 2 decades.

Siddra began to be considered around 2005, starting shortly afterwards with the signing of a macro-agreement for a University-Business partnership between Fertiberia and various universities.

The Siddra system is the result of a partnership between Fertiberia and various universities in Spain. Such universities include: Polytechnic University of Valencia (UPV), Miguel Hernández University of Elche (UMH) and the University of Alicante (UA). Numerous researchers from these universities have participated in the development of the Siddra system while working closely with staff from Fertiberia's Agronomic Service and R&D&I Department.

In 21st century agriculture, there is an increasing need for agricultural analyses, including plant, soil and water analyses. With the results of these analyses, we will be able to know, among other things, the fertility of our soils and the nutrient balance of our plants. At Fertiberia, as an innovation we provide the most modern tables for soil interpretation and also develop and improve several foliar interpretation systems.

There are many methodologies for the interpretation of foliar analyses. Five of these interpretation methodologies have been selected, developed and improved in the Siddra system. For traditional interpretations, we the Ranges of Normality. For more refined interpretations, we have the Standard Deviation Index (IDS). And for much more complex interpretations, even outside the traditional sampling period, we have the Integral Diagnostic and Recommendation System (Dris), the Modified Dris (M-Dris) and the Nutrient Diagnosis and Composition (CND) system.

Traditionally, one of the weaknesses of all these foliar interpretation systems was the limited number of existing standards to be able to use them, given that the availability of numerous analytical results of the different crops to be able to study them is one of the basic tenets in developing new interpretation standards. The larger the study database, the better the results that will be obtained.

At Fertiberia, we have a database with over 50,000 agricultural analytical results from more than 2 decades of work at the service of the farmer. In addition, more than 10,000 targeted analyses have been carried out on various crops for the Siddra project. The result of all these studies has been the generation of 5,000 new foliar interpretation tables for woody crops and 3,000 new foliar interpretation tables for herbaceous crops.

To access the diagnosis and optimised recommendations of the Siddra system, you must be a customer or distributor of Fertiberia fertilisers.

The Siddra system is a value-added service offered by Fertiberia free of charge, so it costs the farmers nothing and optimises their investment in plant nutrition products, knowing the environment will be respected as much as possible.
