I was provided with a link to this article by heritage:

What caught my eye was the lime application formula which is:

tons CaCO3 / acre = Ac [(desired pH - soil pH) / (6.6 - soil pH)]

What that means is if the soil is 6.6 you apply infinite lime. If the soil pH is 6.5 you apply twice as much as if it was 6.4... This formula screams inaccuracy and I was curious if anybody could help with some direction given soil acidity, pH, etc.
