What contributes to a higher aggregate stability in forest soil? Organic matter, known to increase the stability of unfrozen aggregates with diameters greater than 0.25 mm, also strengthens aggregates that are later subjected to freezing stresses, providing the water content at freezing is not too great.
What soil constituent is responsible for high aggregate stability of forest soil? The calcium ion (Ca2+), through its cationic bridging effect on flocculation of clay and organic matter compounds, has a crucial role in the formation and stability of soil aggregates. Calcium can exchange with sodium on exchange sites.
What are the three major factors influencing aggregate stability in soils? The stability of aggregates is affected by soil texture, the predominant type of clay, extractable iron, and extract- able cations, the amount and type of organic matter present, and the type and size of the microbial popula- tion.
What can you do to increase aggregate stability? Aggregate stability increases with organic matter content in the soil and can be improved through a combination of management practices such as reduced tillage, adding organic matter amendments, and increasing the amount of crop residues and organic matter retained in the soil.
