Everybody say that 1 ppm equals 2 lbs per acre on 6 inch soil sample, yet different extraction methods have different ppm readings, wouldn't that result in different fertilizer recommendations?

2:45 - Brian mentioned his goal is to get the field to 100ppm of available Phosphate. Is my understanding correct that the P1 test should then target 44ppm of P ? I calculated 100ppm P2O5 x 0.44 = 44ppm P? Please help me understand if this is correct - thanks!
