GENERAL 



1365. Anonymous. Fertilizers for fruits. Amer. Fertilizer 52 s : 59-64. 1920.— A discus- 

 sion of fertilizer experiments with fruits is given and definite fertilizer formulae for different 

 soil conditions are recommended. — J. J. Skinner. 



1366. Anonymous. Soil fertility experiment in the Middle V/est. Amer. Fertilizer 52 6 : 

 101. 1920. — The number of plots and acres in soil fertility experiments in the Middle Western 

 States are as follows: Ohio has 275 acres and 3,000 plots; Illinois, 1,115 acres; Indiana, 306 

 acres; Wisconsin, 103 acres; Iowa, 552 acres in 1,975 plots; and Kansas, 59 acres in 582 plots. 

 — J. J. Skinner. 



1367. Fippin, Elmer O. The status of lime in soil improvement. Amer. Fertilizer 52 5 : 

 118-124. 1920. — A discussion of the use of lime materials and the effect of lime on soils. — 

 J. J. Skinner.

 Forest. Jour. 3 : 71-72. 1920— See Bot. Absts. 6, Entry 1032. 



1369. Kelley, W. P. The present status of alkali. California Agric. Exp. Sta. Circ. 

 219. 10 p. 1920. — The author discusses the methods of prevention and the treatment of 

 alkali lands. Saline irrigation water is to be avoided and the water table should be kept 

 below the capillary reach of the surface. The leaching of excess salts from the soil involves 

 the matter of drainage. Drainage, accompanied by flooding, is used successfully to remove 

 white alkali from soils. Black alkali requires neutralization before it can be leached from 

 soils if present in large amounts. Gypsum or some other flocculating agent should be added 

 before flooding soils containing small amounts of black alkali. — A. R. C. Haas. 



1370. Maquenne, L., and E. Demoussy. Sur l'absorption du calcium par les racines des 

 plantes et ses proprietes antitoxique vis-a-vis du .cuivre. [The absorption of calcium by plant 

 roots and its antitoxic properties with respect to copper.] Compt. Rend. Acad. Sci. Paris 170: 

 420-425. 1920.— See Bot. Absts. 6, Entry 1314.

 3: 112-113. 1920.— See Bot. Absts. 6, Entry 1044. 



1372. Worth, F. J., and Maung Po Saw. Absorption of lime by soils. Memoirs Dept. 

 Agric. India 5: 157-171. 1919. — The soils used in the test were Hlegu, Hmawbi, Mandalay, 

 Pwinbyu, Hopin and Sahmaw. The work indicates a new method for estimating the lime 

 requirements of soils. The method is based upon the absorption of calcium bicarbonate by 

 a solution of the soil sample. Lime absorption curves are graphically represented for the 

 above soils. — F. M. Schertz. 



ACIDITY AND LIMING 



1373. Lipman, J. C, and A. W. Blair. Lime as a factor in maintaining soil fertility I. 

 Rotation without legumes. Proc. Soc. Promotion Agric. Sci. 39: 124-134. 1919. — A series of 

 experiments covering a period of ten years and designed to show the effect of lime on the nitro- 

 gen content of the soil as well as the yields of non-leguminous crops, are described. The crop 

 rotation was at first corn, oats two years, wheat, timothy, but this was later changed so that 

 there was but one year of oats and two of timothy. The results indicated: 1. A greater loss 

 of nitrogen in the limed than in the unlimed plats. 2. The yield of dry matter on the limed
