The nitrate of soda plot, which, asstated, has a tendency to become basic on account of the basicresidue left when the nitrogen is taken up, gives better yields thanthe ammonium sulphate plot, which has a tendency to becomeacid. Effect of Lime on Crops an Acid Soil.^—Benefited by Lime.—The following gives the ascertained effect of lime on variouscrops as found by experiments such as described above:. Fig. 61.—Sorghum on acid soil, (A) limed and nitrate of soda, (B) unlimedand nitrate of soda, (C) limed and sulphate of ammonia, (D) un-limed and sulphate of ammonia. Rhode Island Station. Alfalfa, asparagus, barley, beets, clover, celery, cauliflower, cur-rants, cabbage, cucumbers, corn, lettuce, mangelwurzel, onions,okra, oats, peas, peanuts, pepper, parsnip, pumpkin, sorghum,salsify, seed fruits, stone fruits, squash, spinach, sugar beets, saltbush, timothy, and tobacco. 1 Wheeler, Farmers Bulletin No. 77, U. S. D. A. soil, di;ficie;ncie;s 253 Indifferent to Lime.—Blackberries, millet, potatoes, rasp-berries, rye, and red top grass. Injured by Lime.—Cranberries, cowpeas, sheep sorrell, lupine,serradilla, and watermelon. In these experiments, it will be noted that the plants were sup-plied with an abundance of phosphoric acid, potash, and being the case, the beneficial effect of the lime could not beto render p
