If soils are too acidic, phosphorus reacts with iron and aluminum, making it unavailable to plants. But if soils are too alkaline, phosphorus reacts with calcium and also becomes inaccessible. However, liming can influence other ways by which phosphorus might become available to plants.

Liming the soil can be a long-term investment and benefits need to be weighed over time.

A full analysis of soil samples can help growers raising spring and winter wheat optimize fertility levels in soils and increase yields by as much as 6-12 bushels, says Washington State University Extension.

Washington State University researchers offer a new publication to explain how soil pH affects root diseases and provide recommendations on mitigating adverse effects.

Regular soil sampling is essential for balancing soil nutrient levels and can serve as a barometer of soil health and productivity, says Penn State Extension.

This agronomy fact sheet offers a summary of about a dozen important points about soil acidity and ag lime.

Soil testing is a very profitable practice to manage fertility input cost and promote environmental stewardship.
