| I tried one of them, but can't remember which one. I guess
my answer is, if you put less P205 in than you take out in the
seed and/or straw you a only mining the soil and it is going
to catch up to you in a few years. There is a lot of unavailable
phosphorus in the soil, but either of these products makes phosphorous.
It is a rolling game phosphate you apply this year is only partly
available, but some is also available from what you applied 10 years ago.
They may help in root development, but it is a false economy
to say they will save fertilizer requirements on the long term. | |
