Soil Aggregate Stability

Flashcards
0/5
Plate-like Soil Aggregates
Their flat, horizontal plates can impede water and air flow; compaction and clay content greatly influence their stability.
Blocky Soil Aggregates
Essential for nutrient cycling; factors like clay content, drying and wetting cycles, and chemical cementation affect their stability.
Single Grain Soil Aggregates
Not true aggregates since particles behave individually; found in sandy soils where organic matter and moisture are limited.
Granular Soil Aggregates
Important for allowing root growth and water movement; stability is affected by soil organic matter, microbial activity, and tillage.
Prismatic and Columnar Soil Aggregates
Their vertical orientation aids deep water percolation; affected by factors such as sodium content, swelling clays, and freeze-thaw cycles.
