Water stable aggregates in soil increase by addition of

Water stable aggregates in soil increase by the addition of P-fertilizers.
Soil aggregation could reduce the loss of organic P in aggregates and increase the absorption of inorganic P by silt and clay particles.
Aggregate stability refers to the ability of soil aggregates to resist disruption when outside forces usually associated with water are applied.
Wet aggregate stability suggests how well a soil can resist raindrop impact and water erosion, while the size distribution of dry aggregates can be used to predict resistance to abrasion and wind erosion.
