Blvd d'Espair Bowhill, Sth Aust | Hi Ed.. Nice to make contact with you again! It's been a while.
The 20 ppm results you mentioned.... please excuse my appalling chemistry knowledge, but are we talking P, or P2O5 with that 20 ppm?
I ask because i have been confused before, until I runderstood that you guys refer to Phosphate fertiliser, whereas we refer to phosphorous fertiliser..
Example...... to me granular DAP is 18:20:0, and MAP is 10:22:0. I dont know if that method carries through to your soil test results , or not .
Do your tests show levels of actual P , or P2O5..? |
Foliar P
