availability of phosphorus to reduce the growth of grass and yet keep it strong in the ab-
sence of dandelions.
The object is to restrict photosynthesis capacity of leaves by managing the conversion
and release of phosphorus on a diet of “one meal'' per day. Actually, we do not want a lot
of soluble phosphorus on a lawn. It needs a good supply of zinc regulated by a calcium
base, not too much nitrogen — just enough to etch the phosphate needed to grow a day at
a time. The phosphorus should be lazy and slow, and at a balanced pH of 6.5. Never apply
nitrogen or phosphorus fertilizer. Instead use gypsum and sulfur as needed to have a slow
growing, healthy and vigorous lawn and watch neighbors wear out their lawn mowers. A
pH range of 6.2-6.6 happens to preside over actinomycete mold balanced activity, mineral
release — and as with all other weeds, there has to be a reference back to calcium and its
colloidal function.
The dandelion is not very important in crop production, and might be excluded from
this roster except for its negative popularity.
