Sounds like a religious statement, rather than a scientific one.
Here in Minnesota, they worry about the phosporous, because it grows
too much algea, and that makes the lakes poisonous. Kills fish, makes
people sick just breathing it. The problem here is from both lawn
chemicals (in the city) and from agriculture and cattle pasture (too
much manure and urine?).
These points are well taken and understood. My sympathy.
They still left out the problem and the potential solutions.
That is true, they want us to believe that lawn fertilizer is a
significant portion of the water pollution problem of the state. After
all, if they talk like that, it distracts people from really looking
into the problem. It is one thing in the city, and there are other
things in the water table- like in my town, the old creosote plant
which poisoned some wells.
A far bigger water pollution issue is the decades old chemical residue
from 3M, which is a serious problem that seems to keep being covered
up. That chemical (Iforget which one it is) pops up in odd places, not
exactly where one would expect it- so it has migrated. Also, the
pollution event predates our current understanding in pollution
control.
Back to lawns, they do say to not use much on the lawns, but you really
have to dig to get the info to keep a lawn healthy without chemicals.
It isn't easy. I did find some organic fertilizer at Home Depot, the
man said it was a oldie but a goodie, been on the market for a very
long time. And had nothing to do with Miracle grow. I guess it is all
purpose, & balanced. I plan to give it a try when I get around to it.
I did take a class on soil science, so your triad sounds familiar-
(smile) but it was a long time ago, and we all know that classes are
great, but experience is the best thing.
Soil Science was not mentioned. Yes, I know a little about that also.
Specific things must exist in soils in order for them to hold on to
nutrients. I guess they gave no credit or discredit to the lousy,
ruined, over used and dead soil. Tons and tons of topsoil are washed
into the rivers and oceans.
Recently a relative purchased some land about 25 miles from the city.
He asked me to go by and select a garden spot.
I did as he asked and hated to tell him.
You have no place. There is NO TOP soil on that hill. You cannot
grow anything unless you build some raised beds or haul in some
topsoil.
The three main elements of soil are, Sand, Silt, and Clay.
Other minor components exist, or better exist.
Darn, I guess I best set up another list for Fertilize, Organics, and
Growing secrets. Not sure I want to give away all my secrets yet.
I could teach some of you how to grow things, and I might even use
organic stuff. In actuality I do, as I said, from 3 to 6 different
items. I only disagree with the technical concept sold to the people.
I don't disagree with the value and the results.
But I have a hard time calculating the ppm for organic stuff.
I like numbers games when they can apply.
