Fertilizer experiments in Smaalenene, Norway, F. H. Weren- 

 SKIOLD (Norsk Landmansblad, t896, Xo. 32, pp. 377, 378). — The object 

 of the experiments was to investigate the effect of lime on marsh and 

 clay soils sown to oats. They were conducted on 7 different farms in 

 Smaalenene district, Norway. The fertilizers applied were Thomas 

 slag and nitrate of soda, with or without the addition of lime. The 

 rather wet season, in connection with the (under the conditions) some- 

 what heavy application of nitrate of soda caused the oats to lodge on 

 all farms. It was noticed that the oats on the limed plats lodged first, 

 the lime evidently converting a portion of the nitrogen of the soil into 

 available form, and thus acting like one-sided nitrogen fertilization. 



The following table gives the average results for the 2 classes of soils 

 as regards the yield and the chemical composition of the oats and 

 oat straw produced.

Some of the principles which should determine compensation for the use of 

 foods and manures, R. WarixGTON (London: Vinton .V ( '«., j>p. 44). — This is a discus- 

 sion based largely upon experimental work at Rothamsted and Wolmrn ontheamount 

 which should be paid by an incoming tenant to an outgoing tenant for permanent 

 improvements due to use of fertilizers and feeding stuffs on the farm as provided for 

 in the Act of Parliament of 1883.

"Natural plant food;" claims made for it and its value, 13. W. Kiegore (Missis- 

 sippi Sla. Bui. 43, p. 14). — Analyses of this material are reported which indicate that 

 it is a "low-grade natural phosphate of too poor a quality to be used in the manu- 

 facture of acid phosphates or other fertilizers." Such a phosphate can be bought at 

 the mines for from $2 ta $3 per ton, while the price asked for the so-called " natural 

 plant food" was $11 to $17 per ton.
