| Abstract: | A correction factor for lime quality ( F ), is described, which can be used to convert CaCO3 requirements into recommendations for commercially available liming materials. A model is presented that relates values of F to the properties of both the liming materials and the soils to which the materials are applied. The results of independent tests demonstrate that the model is capable of predicting suitable values of F for a wide variety of different soil-lime treatments.
A procedure is described for estimating the amount of liming material required to adjust the pH in soils with widely varying organic matter contents. The procedure incorporates all the models and relationships developed in this study and appears to provide a more comprehensive method of evaluating the lime requirement of temperate acidic soils than any other method currently available. |
