I and many agree.
Pasture analyses are 100 times more useful and accurate and easier to read.
New Zealand uses Olsen P for phosphate and gets way out figures like 90 for
peat soils which are only about 20.
Olsen P takes a year or two to rise after applying P and takes years to drop
if none is applied.
