Manures in General 



applied as a nitrate dressing in the month of May. 

 It is an abominable fraud. 



The adulteration of animal charcoal with the 

 calcined residue from distilleries, containing cyanures, 

 is also harmful to vegetation. 



Some sulphates of ammonia and gas limes also 

 contain cyanures without being adulterated. 



As it is not advisable or reasonable for the farmer 

 to experiment at his own risk, it is necessary to have 

 recourse to analysis wherever possible. 



The farmer should also be familiar with the 

 way to set to work in taking a sample, etc., and 

 ought, besides, to know the law which protects him 

 against adulteration. That is why at the end of 

 this brochure we have included a copy of the Law 

 on Fertilisers and Feeding Stuffs. 



The use of chemical manures enables us to obtain 

 much better crops. Where formerly manures were 

 altogether insufficient in comparison to the work of 

 reclaiming the land, or where those obtained were 

 incapable of supporting the farm stock, however 

 reduced, now, thanks to artificials, we get mag- 

 nificent results, and moreover these results are 

 economically obtained. For very often because of 

 the lack of a single fertilising element in the soil, 

 formerly the whole crop would be reduced to a 

 minimum, whereas in many cases it only required 

 the addition of Ph. Ac, for example, to increase the 

 capacity of the soil to an incredible extent. Not 

 only have the crops been increased in quantity 

 and that economically, but also the intrinsic quality 

 of the results is much improved. This fact is 

 not perhaps sufficiently grasped by agriculturists.
