I want to make the point again that people should not
confuse SOLUBLE nutrients with total nutrients. The total
pool includes what is soluble. But do not be mislead
by chemistry reports where the only portion, and a minor
portion, of the total nutrients in a soil are reported.
I have yet to find a soil - and by that I mean something
that actually meets the definition of soil that Hans Jenny
put forward - that lacks any nutrient when TOTAL nutrient
levels are considered.
Any soil can lack nutrients in the soluble pool. But
the function of a healthy food web of organisms is to
solubilize nutrients from not-plant available into plant
available, or soluble forms. So if the biology
is properly balanced, soluble nutrients will be adequate to
supply the plant, and will be constantly replenished.
Where sand, silt, clay, aerobic organisms and adequate
organic matter is present to feed those organisms, the
nutrients required to grow plants are present.
