SOILS — FERTILIZERS. 823 



(1913), No. 8, pp. 957-959; Jour. Agr. Prat., n. set., 26 (1918), No. S2, pp. 175, 

 176). — Analyses are reported which show that there is no relation between lime 

 and phosphorus in basic slag, i. e., that a slag low in phosphorus is not neces- 

 sarily high in lime, and vice versa. 



The valuation of basic slag', D R. Edwardes-Ker (Jour. Southeast. Agr. Col. 

 Wye, 1912, No. 21, pp. 296-301). — It is proposed that the valuation be based on 

 both the total and the citric acid soluble phosphate and not on the latter alone 

 as at present; "that a value of, say 9 d. [18 cts.] per unit of phosphate 

 of lime be given to the percentage of insoluble phosphate (i. e., the difference 

 between the total phosphate and the citric soluble), a proportionately lower 

 value than that usually adopted being taken for the unit of citric soluble 

 phosphate, say 1 s. 7 d. [38 cts.]." 



The action of lime in Thomas slag (Chem. Ztg., 37 (1913), No. 92, pp. 925, 

 926). — Investigations are briefly referred to which indicate that the lime of 

 Thomas slag is very effective in soil requiring lime. 



Calcium fluosilicate as a new lime fertilizer or amendment, U. Axvisi 

 (Rend. Soc. Chim. Ital., 2. ser., 4 (1912), No. 11, pp. 293, 25^).— Good results 

 with this material as a fertilizer for grain are reported. 



Injurious effect of heavy applications of lime on upland moor soils, A. 

 Densch (Landtv. Jahrh., U (1913), No. 1-2, pp. 331-352; abs. in CentU. Bakt. 

 [etc.], 2. Abt., 39 (1913), No. 4-7, pp. 159, i60).— Large applications of lime 

 on such soils resulted in a partial reduction of nitrates to ammonia and in the 

 production of nitrites which persist for a considerable time in the soil. This 

 causes not only loss of nitrogen but also direct Injury to plants. In connec- 

 tion with the nitrites nitro and nitroso compounds are also formed which axe 

 injurious to plant growth. 



Chemical causes and character of the injurious effect of large amounts of 

 lime on peat soil, G. A. Ritteb (FiihUng's Landw. Ztg., 61 (1912), No. 18, pp. 

 593-60J,; abs. in Zentbl. Agr. Chem., 42 (1913), No. 4, pp. 239-242; Jour. Chem. 

 Soc. [London], 104 (1913), No. 609, I, p. S12; Centbl. Bakt. [etc.], 2. AM., 39 

 (1913), No. 4-7. PP- 158, 159). — The iujuiious effects of heavy liming on moor 

 soils ax-e thought to be due to purely chemical causes, viz, to the formation 

 of ])oisouous oxidation products of humus. 



The chemical composition of garbage and street sweepings of Montevideo, 

 J. Schroder (Rev. Inst. Agron. Montevideo, 1913, No. 12, pp. 20-22). — Analyses 

 of several samples are reported. 



Analyses of registered fertilizers, J. T. Willakd, C. O. Swanson, and R. C. 

 Wiley (Kansas Sta. Bui. 187, pp. 71-81). — Analyses and guarantied composi- 

 tion of fertilizers inspected under the State law are reported with a statement 

 of receipts and disbursements, lists of dealers, and a schedule of trade values of 

 fertilizing materials. As a rule the composition of the fertilizers was found to 

 be " within the limits of tolerance provided by the law which permits a defi- 

 ciency of not more than 1/15 of the guarantied percentage without such defi- 

 ciency being taken as evidence of fraudulent intent." 



Analyses of commercial fertilizers, J. H. Kastle and H. E. Curtis (Ken- 

 tucky Sta. Bui. 168, pp. 387-525). — Analyses of 672 brands of fertilizers regis- 

 tered for sale in Kentucky during the year 1912 are reported. The results 

 showed that in most cases the fertilizers came fully up to their guaranties. 



Analyses of commercial fertilizers, B. L. Hart well et ax. (Rhode Island 

 Sta. Insp. Bui., 1913, Sept., pp. 2-8). — Analyses and valuations of fertilizers in- 

 spected to date under the State law are reported.
