“…Bear ( 2) concluded from his studies of Dekalb soil at the West Virginia Experiment Station that the organic matter of a depleted soil can be increased and maintained in a rotation system through the systematic use of mineral fertilizers without the return of crop residues other than the roots and stubbles. Also, that the nitrogen content of the soil in like manner can be increased and maintained with9ut the use of mineral nitrogen or farm manure.…”

“…They state that Drew's organ- This is a denitrifying organism which produces ammonia by the reduction of nitrates. Bear and Salter (2) show that the lime requirement (Veitch) of the West Virginia Agricultural Experiment Station fertility plots is less where the content of organic matter has been increased, and suggest that this decrease may have been due to the precipitation of calcium from solution by the humus in the soil, whereby it was prevented from being lost in the drainage water.…”

Receivedfor publication September12, 191? INTRODUCTION Limestone regions are noted for their fertility. Alfalfa, red clover, bluegrass, and corn are among the crops which thrive best on limestone soils. Those soils which do not naturally contain carbonate of lime are usually made more productive by applications of lime or limestone. Extensive investigations carried out by the Rhode Island, Maryland, Pennsylvania, Ohio, Illinois, and other agricultural experiment stations have demonstrated the value of lime in either the oxide, hydrate or carbonate form on soils which are acid to litmus. An excellent review of the most important investigational work on the use of lime on acid soils is given by Frear (9). The investigations of Wheeler at the Rhode Island Agricultural Experiment Station, indicate, however, that a number of plants of economic importance thrive on soils which contain no solid carbonate of lime. Some of these plants are benefited by lime, but others are injured by applications of lime. Wheeler (36) says that orchard grass (Dactylis glomerate, L.) and meadow fescue (Festuca elatior, L.) are less injured by soil acidity than Kentucky blue-grass (Poa pratensis, L.) and timothy (Phleum pratense, L.) and that awnless brome grass (Bromus inermus, L), red top {Agrostis alba var. vulgaris, Thurb.), and Rhode Island bent (Agrostis canina, L.) do not seem to be susceptible to injury even on decidedly acid soils. He also states (37) that Concord grapes are apparently indifferent to the lack of lime and that cranberries, raspberries, and lima beans are injured by liming, the last named growing splendidly on soils so acid as to entirely destroy lettuce, spinach, onions, beets and asparagus. In ln> latest publication on this subject Wheeler (38) gives a summary of his work in which he shows that plants vary in their requirements from those which are injured by applications of lime even to a very acid soil, to those which are unable to live on an acid soil and are benefited remarkably by lime. Coville (6) states that the blueberry, cranberry, strawberry, blackberry, red respberry, potato, sweet potato, rye, oats, millet, buckwheat, red top, carrot, turnip, cowpea, hairy vetch, crimson clover, soybean, lupine, and serradella are adapted to acid soils. He concludes, "soil acidity is not always 433 SOIL SCIENCE,VOL. IV, NO. 6 434 FIRMAN E. BEAR an objectionable condition which invariably requires lime" and "under certain conditions, a complete system of acid agriculture is practicable." Harter (14) writes that liming has been shown to be beneficial to all crops on Norfolk sqils with the exception of beans, peas, and tomatoes. Kossovitch and Althausen (26) report that, while the liming of acid podzol soils strikingly increases the yields, the limit of increase is at about the point of neutralization and that an excess injures the plants. No statement is made as to how the point of neutralization was determined. Heinrich (15) concludes that the determination of lime in a soil, by digesting with 10 per cent hydrochloric ac...
