How much lime per acre in Illinois?

Illinois's land-grant extension publishes a method — not a one-size-fits-all rate. Illinois Agronomy Handbook Ch. 8 Table 8.3 is staged, but its 9-inch incorporated rate and one-third no-till/pasture rule require a tillage/depth input contract before calculation can ship. Live calculator uses this state's published method and citation. Enter the required soil-test values in the free calculator for tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.

Frequently asked

How much lime per acre does Illinois recommend?

It depends on the inputs Illinois's land-grant method publishes — not a single national number. Illinois Agronomy Handbook Ch. 8 Table 8.3 is staged, but its 9-inch incorporated rate and one-third no-till/pasture rule require a tillage/depth input contract before calculation can ship.
