Organic Matter, needs to be working its way into the soil to become Soil Organic Matter(SOM) to actually have any value... a pellet of Milorganite sitting on top of the soil is not doing any good for the nutritional value of the roots...
Microscopic elements becoming water soluable and perculating through the soil profile into the depths of the root zone is the basic image you want to start with...

Sandy soil becomes brown soil when SOM increases... Clay soil has a much harder time and that is when aeration comes in handy, before the addition of compost...
There are other and better ways of understanding the movement of OM through the soil such as worms or tiny crustaceans which is also worth noting... the huge unseen networks of fungal mycelium of all different varieties building soil structure at the very basic levels are being fed with Organic Matter...

The soil is not a giant cake that is put together by a 'recipe' of various ingredients,,, but a living organism that will perform best with a comfortable blend of food, water and air...
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
