The prevailing view in the 1940s and 1950s was that P availability was maximized near neutrality (soil pH 6.5–7.5), and decreased at higher and lower pH. [29] [30] Interactions of phosphorus with pH in the moderately to slightly acidic range (pH 5.5–6.5) are, however, far more complex than is suggested by this view. Laboratory tests ...
The degree to which a given amount of lime per unit of soil volume will increase soil pH depends on the buffer capacity of the soil (this is generally related to soil cation exchange capacity or CEC). Most acid soils are saturated with aluminum rather than hydrogen ions. Soil acidity generally results from hydrolysis of aluminum. [4]
Soil pH Test: For a very low price, your local Extension office will test your soil pH. To have a test completed, simply collect one cup’s worth of soil and remove all debris, such as sticks ...
This compound causes rainfall pH to be around 5.0–5.5. When rainfall has a lower pH than natural levels, it can cause rapid acidification of soil. Sulfur dioxide and nitrogen oxides are precursors of stronger acids that can lead to acid rain production when they react with water in the atmosphere.

Some effects of agricultural lime on soil are: it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity [1] it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils.
