Top processes

Aggregate formation and pore structure

1 step

Polyvalent cations and oxides bridge clay to organic matter

Nutrient availability and leaching

1 step

Phosphate sorbed to Fe and Al oxides, precipitated with Ca at high pH

Mineral-associated organic matter (MAOM) formation

1 step

Polyvalent cation bridging with calcium and clay

Occlusion in aggregates

1 step

Primary particles flocculate with clay and cations

Base cation cycling (calcium, magnesium, potassium, sodium)

1 step

Calcium bridges clay and organic matter, stabilizing aggregates and organic carbon

Mineral surface area, reactive metals and the saturation of mineral-associated carbon

1 step

In neutral to alkaline soils exchangeable calcium and clay matter more than clay content alone, while reactive Al and Fe explain most variation in acidic soils
