Main steps of the preparation of the root-soil specimens: (a) foil-wrapped seeds on germination filter paper, (b) sand deposition at controlled bulk density by air pluviation, (c) positioning of the germinated seed in the cell during sand pluviation, (d) watering of specimens using water enriched of nutrients.
