A method and assembly are described to dry soil for use in testing a variety of physical and chemical parameters such as phosphorus content. The method broadly involves the steps of particle size reduction, subjecting the sample to an airflow and also heating of the soil sample. It is the inventors experience that by use of the method of the present invention, samples can be prepared for accurate analysis with as little as 20 minutes rather than the more traditional methods which take 20 to 24 hours.
Procédé et ensemble permettant de sécher un échantillon de sol en vue de l'analyse de divers paramètres physiques et chimiques, p. ex. teneur en phosphore. Le procédé comprend de manière générale les étapes consistant à : réduire la taille des particules, soumettre l'échantillon à un flux d'air et chauffer l'échantillon de sol. Ce procédé permet de préparer en 20 minutes seulement des échantillons en vue d'une analyse précise, la mise en oeuvre des procédés classiques nécessitant entre 20 et 24 heures.
