What is population holding capacity in reference to environmental science?

As the size of soil particles decrease, how does water-holding capacity, nutrient-holding capacity ....?

• As the size of soil particles decrease, how does water-holding capacity, nutrient-holding capacity, infiltration, and workability change??? Do they increase or decrease?

• Answer:

  water-holding capacity increases as the particles diminish size (texture) or size of lumps (structure) the extreme case being we loose the soil as slurry. Workability is the key, there is a right size for infiltration and nutrient holding specially in tight up soils where plants can drown size particle check out is very important.
