Many experiment stations and many practical farmers have found lime beneficial to crop production. The kind of lime used has varied according to its accessibility. Some have used calcium oxide, some calcium carbonate, while others have used dolomite. Of recent years some of the experiment stations have advocated large applications of ground limestone rock, either as a carbonate or dolomite. The claim made by these stations is that the loss incurred by the larger application is not great enough to be of material value. In fact it is claimed that the loss is not great enough to pay the extra cost of small but frequent applications. There are several limited pieces of work bearing upon the question but the data are too circumscribed to permit of definite conclusion.
