“…I N 1914 a contribution from this station (15) showed that, as a liming material, calcium silicate (wollastonite) ia equal, or even superior, to calcium carbonate. Similar findings were obtained elsewhere in subsequent studies with certain specially processed furnace slags and by-product silicates (1,4,7,8,23). Cowles (6,7) contended that the beneficial effects of calcium silicates are attributable to the effectiveness of their silica content in functions related to utilization of phosphates by plants.…”

DECENT experiments with several sources of lim-.r\.. ing materials on light textured soils of the Coastal Plain resulted in outstanding yields from use of blast furnace slag as compared with other sources of lime (II). Earlier investigations have shown that the use of common sources of lime in excessive amounts induced boron deficiency and decreased yields of some crops. It was observed that over-liming injury did not occur on these sandy soils when blast furnace slag was added in amounts equivalent in neutralizing value to that of other sources causing injury (10). It appeared that blast furnace slag supplied boron required for increased growth.Several workers (I, 2, 3, 4, 5, 6, 7, 9, 15, and 17) have reported favorable results from use of calcium silicate and blast furnace slag in comparison with other liming materials.The specific objectives were to determine by greenhouse, field, and laboratory investigations, with particular emphasis on field results, the comparative values olE (a) representative blast furnace slags 3 and agricultural limestone in Alabama, (b) different rates of application of blast furnace slag, and (c) different finenesses of blast furnace slags. ExperimentalField experiments were conducted on Norfolk loamy sand near Auburn, Ala.; on Lloyd sandy clay loam at the Piedmont Substation, Camp Hill, Ala.; and on Hartsells very fine sandy loam near Boaz, Ala. (The experiment was set up as a randomized block design and replicated three times.) The plots were one one-hundredth of an acre in size. Companion tests were conducted in the greenhouse at Auburn. Two cropping systemsalfalfa grown continuously arid a crimson clover-corn succession All blast furnace slags used in these tests were air-cooled slag.were used in these tests.In the fall of 1946, one-half of the liming material was applied and turned under. Two weeks later, the other half of the lime and the fertilizer were applied and disked in. At this time, the alfalfa and the crip1son clover were seeded.The original fertilizer treatment for alfalfa was 80 pounds of P20 5 and 180 pounds of K 2 0. On plots receiving boron, 20 pounds per acre of borax was added initially. The annual fertilizer applications, made after the first alfalfa cutting each year, were the same as outlined above except for borax, which was reduced to 10 pounds per acre. Both crimson clover and corn were fertilized at the rates of 300 pounds of 0-14-10 per acre. A minor element mixture, consisting of 10 pounds of manganese sulfate, 10 pounds of zinc sulfate, and 5 pounds of borax per acre, was also added to each crop on those plots to receive minor elements. These treat· ments were added just before,each planting date.Alfalfa was harvested three or four times annually, and the hay was removed from the plots. Hay yields were computed by taking oven-dry weights and adding 15% for moisture. The green weight yield of crimson clover was taken, and the clover was re· turned to the soil as green manure. Corn was harvested from the two inside ;rows of four-row plots, and the yield ...
