if you want to raise phos-I think you have to go 10 times the rate to get a move of 1ppm-if your crop calls for 70# removed-and you want to raise your soil test 7ppm-you would have to put on twice as much-depending on where your soil levels are-if in medium to high fertility-it takes more to raise it 1ppm then if your soil is low-fertility
