{Tool} Assessing soil structure with two simple methods : Spade Test and mini 3D soil profile. [Evaluer la structure de son sol grâce à deux méthodes simples.] Creator(s): ARVALIS, Institut du végétal. Issuing Organisation(s): ARVALIS - Institut du végétal. (2017)

The spade test and the mini 3D soil profile are diagnosis tools to assess soil structure. Both tools are a simplified version of the soil profile diagnosis method that quickly provides information to the user and helps for decision making (e.g. tillage operations). The spade test only requires a spade and a tarp whereas the midi soil profile requires a telescopic loader with a pallet fork. The video presents the two different tools and their related guideline document. The leaflets explain how to extract a soil block and interpret the observed soil structure. Both leaflets contain an interpretation table for scoring the soil structure based on the observation of the clods. The tools are applicable both for organic agriculture and conventional agriculture and the tests are applicable in all European pedo-climatic conditions.

Summary translation

Le test-bêche et le mini profil de sol 3D sont des outils de diagnostic pour évaluer la structure du sol. Les deux outils sont une version simplifiée de la méthode de diagnostic du profil cultural et fournissent rapidement des informations à l'utilisateur pour l’aide à la prise de décision (par exemple, les opérations de travail du sol). Le test-bêche ne nécessite qu'une bêche et une bâche tandis que le profil de sol midi nécessite un chargeur télescopique avec une fourche à palette. La vidéo présente les deux outils et leur guide d’utilisation associé. Les brochures expliquent comment extraire un bloc de sol et interpréter la structure du sol observée. Les deux brochures contiennent une table d'interprétation pour la notation de la structure du sol basée sur l'observation des mottes et leur assemblage. Les outils sont applicables à la fois pour l'agriculture biologique et l'agriculture conventionnelle et les tests sont valables dans toutes les conditions pédoclimatiques européennes.

EPrint Type:Practice tool
Teaser:The spade test and the mini 3D soil profile quickly assess soil structure
What problem does the tool address?:In case of degraded soil structure (e.g. compaction) assessing soil quality is crucial to further adapt cropping practices in order to restore soil structure.
What solution does the tool offer?:From a block of soil, it is possible to evaluate the soil structure on the first horizons and its porosity. An interpretation grid helps to decide on corrective actions if necessary. Both presented methods provide a quick soil structure diagnosis, compared with a “classical” soil profile pit.
