298 FEEDING WITH SUGAR BEETS, SUGAR, ETC. 



Chilien saltpetre. Furthermore, this product contains 28,000 

 tons of potassium oxid. It necessarily follows that if all the 

 molasses were utilized, farmers would have at their disposal 

 an excellent fertilizing material of the value of $1,000,000. In 

 Germany it was recommended that, in consideration of the low 

 selling price of molasses, the product be practically used as a 

 fertilizer, but this idea was very illogical, as it would be throw- 

 ing away without any possible profit the money that might be 

 derived from the sugar contained in this residuum, to say noth- 

 ing of the non-nitrogenous substances to be found in it. 



By the use of molasses as a forage the farmer returns all the 

 salts that had been previously taken from the soil, which in 

 other words means all the plant foods that have been extracted 

 by the plant during its growth. Furthermore, there is another 

 advantage derived from this molasses feeding, which is that the 

 money profits derived from the same are general] 3^ greater than 

 would have been realized if the residuum were employed for 

 the extraction of sugar. 



Analysis of The Association of Austrian Chemists, during 1901, made the 

 molasses feeds, following resolutions: That the molasses forage combinations 

 should be thoroughly mixed, and that the precaution be taken 

 to constantly bring to the top the lower strata of the feeds, as it 

 is there that the molasses always settles. An average sample of 

 500 grams should be dried at 100 C. and afterwards thoroughly 

 pulverized. Without a previous understanding, this sample 

 should be used for the analysis. The desiccation is done in a 

 small tared receptacle having a suitable stopper hermetically 

 closing the same. 



The total nitrogen is estimated by the Kjeldahl method. 

 To 1 gram of this substance with mercury add 30 cc. concen- 

 trated sulphuric acid. This acid is used in excess on account 

 of the sulphurous acid liberated. 



The nitrogen of the albuminoids is determined upon 1 gram 

 of the substance sprinkled with 100 cc. of water heated to boil- 

 ing point, 25 cc. of a 6 per cent, solution of copper sulphate 

 and 25 cc. of a 12.5 per cent, caustic soda. The addition of the 

 soda is arranged so as not to precipitate all the copper. This 

 precipitate is rapidly deposited and is filtered, and then washed
