Purpose
Soils studied through mineral and organic composition, structure, water, nutrients, organisms and formation across landscapes.
Structure

Entities → interactions → mechanisms → scales → measurement
Treat soil as a living interface, not inert ground.
Soil science links rock, climate, organisms and time in a porous medium that regulates water, nutrients, carbon and plant growth.
Texture & structure
Connect particle size and aggregation to porosity, aeration, water retention and mechanical behavior.
Chemistry & nutrients
Study pH, exchange capacity, redox and nutrient transformations as controls on fertility and contaminant mobility.
Soil water
Relate matric forces, infiltration and drainage to plant availability and groundwater recharge.
Biology & carbon
Examine roots, microbes and fauna as active agents in decomposition, aggregation and carbon cycling.
Keep the boundaries visible.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
soil ≠ sediment
texture ≠ structure
organic matter ≠ soil carbon alone
Questions that organize the Side.
Use these to test whether the model is becoming explanatory rather than merely familiar.
How do mineral surfaces and organic matter jointly control nutrient retention?
Why do soils with similar texture behave differently after management or disturbance?
How quickly can soil properties change relative to the processes that formed them?
What should carry weight here?
Combine field profiles, laboratory chemistry, hydraulic measurements and biological assays; spatial variability and sampling depth must remain visible.
