Fertilisers and Biostimulants
Renolab performs analytical activities on both fertilisers and biostimulants, with a focus on chemical and physical characterisation and qualitative and quantitative analysis.
Accurate analytical evaluation is essential to ensure product quality, consistency and compliance with applicable regulatory requirements.
For both fertilisers and biostimulants, analytical data play a key role in verifying composition, identifying impurities and supporting product development and comparison.
Renolab supports companies through targeted laboratory activities, providing reliable data to assist in quality control, product characterisation and technical assessment.
Analytical Testing for Fertilisers
Renolab performs analytical testing on fertilisers, including:
- chemical and physical characterisation;
- qualitative and quantitative analysis of impurities or contaminants.
These analyses support the evaluation of product composition and the identification of possible contaminants.

Analytical Testing for Biostimulants
For biostimulants, Renolab performs:
- chemical and physical characterisation of active substances;
- qualitative and quantitative analysis of impurities or contaminants;
- comparison between different products through the identification of specific chemical markers.
These activities support the analytical evaluation of product composition and comparison between formulations.
FAQ
What analytical tests are performed on fertilisers?
Analytical testing on fertilisers may include chemical and physical characterisation, as well as qualitative and quantitative analysis of impurities or contaminants.
What analytical tests are performed on biostimulants?
For biostimulants, analytical testing may include chemical and physical characterisation of active substances, impurity analysis and comparison between products through the identification of specific chemical markers.
Why is impurity analysis important for fertilisers and biostimulants?
Impurity analysis helps identify and quantify contaminants or unwanted substances that may be present in the product and supports the analytical assessment of composition.
Can biostimulant products be compared analytically?
Yes. Different products can be compared through the identification of specific chemical markers, which can support analytical differentiation between formulations.
What is chemical and physical characterisation of fertilisers and biostimulants?
Chemical and physical characterisation includes analytical activities used to define the composition and relevant properties of a product or active substance.
