Iron. 



Action of FeSO 4 in various soils. P. M. DELACHABRONNY and L. DESTREAUX. 

 (Bieder. Centr. 1889, 9-14.) The addition of FeSO 4 to soil increased the 

 yield of wheat up to 3 per cent, of Fe 2 O 3 , then it decreased. The same with 

 potatoes, with lucerne, and with hay. FeSO 4 may be applied at the rate of 

 300 kilos per hectare dry, or dissolved 5 kilos per 100 litres. 



Influence of Iron and CaSO 4 in nitrification. P. PICHARD. (Compt. Rend. 

 112, 1455-1458.) According to the Author, Fe has a good influence in soil 

 nitrification. The addition of FeSO 4 is recommended for non-ferruginous 

 soils. 



Iron in plant life. G. STAMPANI. (Staz. Sper., Agr. Ital. 19, 5-33.) Manganese 

 cannot take the place of Fe in the formation of chlorophyll. 



Iron in plants. A. MOLISCH. (Bied. Centr. 22, 336-338.) Iron occurs in plants 

 partly in a loose form (when it may be extracted with an acid), and partly 

 in a closer union with the plant, and can only be detected in the ash. Algae 

 and fungi contain very little, but certain lichens contain much Fe, which can 

 be extracted with an acid. A remarkable case is the fruit shell of Trapa 

 natans, whose ash contain 68 per cent, of Fe 2 O 3 . Insoluble Fe is of very 



general occurrence Iron is necessary to fungi, as well as to 



green plants. Results contrary to this were due to the fact that nutritive 

 solutions were employed which were never quite free from Iron. Fungi 

 are able to appropriate the smallest amount of Fe. 



Employment of FeSO 4 in agriculture. E. BOIRET & G. PATUREL. (Ann Agron. 

 18, 418-440.) .... Sir H. Davy's opinion, in commenting upon the 

 results obtained with FeSO 4 by Pearson, was that FeSO 4 produced CaSO 4 , 

 and on the same theory he explained its injurious action when lime is 

 lacking in the soil. Gris and Dumont in France, and Griffiths in England, 



had good results (y 2 cwt. per acre), but not with cereals 



FeSO 4 is always injurious if the soil does not contain an excess of lime. 



Organic compound of Fe in plants. U. Suzoki. (Bull. Coll. Agric. Tokyo Imp., 

 Univ. 1901, 4, 260-266.) The seeds and leaves of Poligonum tinctorium and 

 those of Indigotifera tinctoria were found to contain 2-84 and 15-5 

 4-0 and 4-3 of crude ash per cent. The seeds of the first had 12-1 per cent., 

 and those of the second 12 per cent, of Fe 2 O 3 ; the leaves of the first 3-11, 

 those of the second 4-8 per cent. The greater portion of Iron is present in 

 a nucleiu-like substance. 



Influence of Iron on barley. P. PETIT. (Compt. Rend. 117, 1105-1107.) Barley 

 was grown in sand freed from Fe, to which the necessary ash constituents 

 were added. Fe was supplied (1) in the form of barley nuclein, (2) with 

 Fe as FeSO 4 , (3) with Fe 2 (SO 4 ) 3 , (4) no Fe. Nuclein and FeSO 4 were both 

 beneficial; Fe 2 (SO 4 ) 3 acted as a poison. 



Assimilation of Iron from cereals. GUSTAV VON BUNGE. (Zeit. physiol. Chem., 

 1898, 25, 36-47.) Cereals in comparison with rice are very rich in Iron. 

 The greatest quantity is in the husk or bran. The Author finds the amount 

 of Iron (in milligrams per 100 grams of dry substance) to be as follows: 

 Rice, 1 to 2; barley, 1-4 to 1-5; wheat-meal, 1-6; barley, 4-5; rye, 4-9; 

 wheat, 5-5; wheat-bran, 8-8. 



Bark of Robinia pseudacacia. (FREDERICK B. POWER. (Pharm. Journ., 1901 

 (IV), 13, 25S-261.) The bark of Robinia pseudacacia contains a toxic 

 proteid, with about 4 per cent, of ash, w r hich contains a considerable amount 

 of Iron. 



Hoots of Dorstenia klaincana. E. HECKEL & F. SCHLAGDENHAUFFEN. (Compt. 

 Rend., 1901, 133, 940-942.) Roots contain a very large proportion of 

 inorganic matter, the ash consisting of CaO and Fe 2 O 3 , the latter in large 

 quantity.
