Nitrate of Soda, unlike other ammoniates and 

 "complete fertilizers," can be mixed with lime or ashes 

 without loss of Nitrogen. 



The fallow in modern agriculture, S. RHODIN (K. 

 Landtbr. Akad. Handl. och Tidskr., 45 (1906), No. 1, 

 57-72, fig. 1). -The evidence and views in regard to the 

 value of bare fallow, especially in Swedish agriculture, 

 are briefly discussed. While bare fallow of loose sandy 

 soils is not to be recommended, because the losses of 

 Nitrogenous substances occurring, generally speaking, 

 exceed the gains through Nitration, this is not the case 

 with other types of soils. Here an accumulation of 

 Nitrates takes place through the fallow, which greatly 

 benefits the following grain crop. 



Field experiments with cabbages in 1903 and with 

 potatoes in 1904 and 1905 were conducted for the pur- 

 pose of determining whether inoculation of sandy soils 

 with fallow soil would prove beneficial on account of 

 the large bacterial content of the latter. The systems of 

 fertilization followed are shown below, the different plats 

 receiving as a basal fertilizer 37 per cent, potash salt and 

 Thomas phosphate, at the rate of 225 to 400 Ibs. per 

 acre, respectively. The Nitrate of Soda was applied at 

 the rate of 300 Ibs. per hectare (121 Ibs. per acre) and the 

 inoculated soil at the rate of 6 cubic yards per hectare.

 and Uninoculated Gravelly Soil.
