Analysis, diagnosis and fertilizer recommendations (Siddra)

How do we do a correct analysis?

Soil

We indicate the characteristics of the soils, evaluate their fertility and find out the potential supply of nutrients in the short and medium term.


Plants

Our analysis will help you check the nutritional status of the plants so you can choose the right corrective fertilization, taking into account the levels of nutrients.


Water

This analysis lets you evaluate the nutrients that can be contributed by irrigation and determine possible problems with mixtures if you use fertigation.


For the farmer

Siddra

The Integrated Fertilizer Diagnosis and Recommendation System, Siddra, is a highly complex tool exclusively for customers of Fertiberia products. This computer application uses the correct interpretation of the results obtained in previous analyses to allow our technicians to make hugely accurate and reliable fertilizer recommendations.

Siddra contains all the parameters involved in the soil-water-plant complex and interprets the results determined in the soil analyses, according to five textures and in four different edaphoclimatic conditions. In addition, it uses the most advanced statistical handling and interpretation systems for foliar analyses, setting out a methodology for interpreting them.

Questions and answers about Siddra

The Siddra system is software created by Fertiberia to diagnose, interpret and recommend based on analyses from its Agronomic Laboratory.

At Fertiberia, we are aware of our responsibility as a leading company in the fertilizer sector, encouraging the rational and proper use of fertilizers. The Siddra system was therefore created to further optimise the interpretation, diagnosis and fertilizer recommendations that have accompanied its agricultural analyses for over two decades.

The ideological concept behind Siddra began to be considered in around 2005, starting shortly afterwards with the signing of a macro-agreement with collaboration between Fertiberia and various universities.

The Siddra system is the result of a collaboration between Fertiberia and various Spanish universities. These universities are the Polytechnic University of Valencia (UPV), the 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, in close collaboration with staff from Fertiberia’s Agronomic Service and Department of Research, Development and Innovation.

In 21st-century agriculture, agricultural analyses of plants, soil and water are becoming increasingly necessary. Among other things, the results of these analyses tell us more about the fertility of our soils and the nutrient balance of our plants. At Fertiberia, one of our innovations is providing the most modern tables for interpreting soils, as well as developing and improving several foliar interpretation systems.

There are many methodologies used to interpret foliar analyses. In the Siddra system, five of these methodologies of interpretation have been selected, developed and improved. For traditional interpretations we have the Ranges of Normality, and for tighter interpretations we have the Standard Deviation Index (SDI). For much more complex interpretations, even outside the traditional sampling period, we have the Diagnosis and Recommendation Integrated System (DRIS), the modified DRIS (M-DRIS) and the Diagnosis System, and the Compositional Nutrient Diagnosis (CND).

Traditionally, one of the weak points of all these foliar interpretation systems was the limited number of existing standards to be able to use them, being one of the basic tenets behind developing new standards of interpretation to get numerous analytical results from different crops in order to study them. The larger the study database, the better the results obtained.

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

To access the diagnosis and optimised recommendations of the Siddra system, you have to be a customer or distributor of Fertiberia fertilizers.

The Siddra system is an added value service offered by Fertiberia free of charge, therefore costing nothing to the farmer, as well as optimising his investment in fertilizers knowing that he will respect the environment as much as possible.
