Single grain structure

Elementary structure

The single grain structure is also called elementary structure and is a type of soil structure .

The soil particles lie loosely next to one another and have no particular type of connection, ie the soil particles are not glued to one another. There is weak cohesion of the particles when wet through water menisci . But they trickle down after drying out . Due to its low water retention capacity , it is only moderately suitable for plants to thrive , and even poorly with greater compaction.

Examples:

• loose sand and silt soils
• Humus particles in raw humus
• Brown earth from fine and medium-sand molasses materials
