GROUND LIMESTONE FOR USE IN NEW YORK STATE.* J. F. BARKER AND W. W. BAER. Five years ago we could learn of but one company in this State producing ground limestone for the agricultural trade and there was one producing marl. On the basis of the merits of this material its demand has increased rapidly until now there are 56 plants in the State engaged in the production and more than a dozen plants outside make extensive shipments to New York farmers. The 56 plants mentioned have a possible capacity of approximately 675,000 tons annually, counting only eight months of the year and a working day of eight to ten hours. PURPOSE OF THIS PUBLICATION. When the present fertilizer inspection law was written, about the only lime of agricultural interest on the market was high grade calcium burned lime used more for spraying purposes than for application to the soil. Accordingly provision was made for inspection of such lime material only as sold for $5 or more per ton and for the determination of calcium alone. With the large volume of ground limestone now on the market, the greater portion of which sells away below the above figure, there has arisen a demand for information regarding the relative value of different products, not furnished by the fertilizer inspection work. Bulletin No. 400 (March, 1915) and the present bulletin have been intended to fill this need. In the preparation of this report aid has been rendered by the County Farm Bureau men, who have collected samples. The data given herein represent the analyses of samples taken by these men and by representatives of this Station during the season of 1916. In a few cases, indicated in the tables, use has been made of data from Bulletin No. 400 where the authors have reason to believe it represents the character of the present product.
