Critical Relative Humidity: Fitosoil’s new methodology

Fitosoil’s new methodology aims at anticipating the enormous negative effect that the hydration of solid fertilizers can have, depending on their composition and the ambient humidity where they are found.

We are pleased to announce that Fitosoil, part of the Cotecna group, has develped a new method to determine the critical relative humidity in solid materials, a critical parameter in solid fertilizer products.

The critical relative humidity (CHR) of salt is defined as the relative humidity of the surrounding atmosphere. The material begins to absorb moisture from the atmosphere and below which it will not absorb atmospheric moisture. When the humidity of the atmosphere is equal to or greater than the critical relative humidity of a salt sample, the sample will take water until the salt dissolves to obtain a saturated solution.
