Rates of reaction of representative agricultural limestones in various soils were highly correlated with reactivity as measured by reaction with the di‐ or trisodium salts of ethylenediaminetetraacetic acid under standardized conditions, and with the calcium carbonate content of the limestones. The trisodium salt seemed superior as a rating reagent but none of the three reactivity indices accounted for all the variation in reactivity of the limestones in the soil. |
