HOW HUMOGEN IS APPLIED 175 



Good results can be obtained by using humogen 

 with other fertilizers, particularly if they are not 

 acid in character, as is the case with many artificial 

 manures and fresh dung. Old rotted stable manure, 

 when mixed with a twentieth part of its bulk of 

 humogen, is a valuable fertilizer, easily applied, and 

 combines the good qualities of both dung and 

 humogen. There is no reason, however, why 

 humogen should not be used alone without any other 

 fertilizer, and so far experiments have demonstrated 

 that alone it will do all that dung and artificial 

 manure, either separately or together, are able to 

 effect. A basis of dung or other bulky organic 

 manure has distinctly beneficial effects on the 

 mechanical texture of the soil apart from any 

 manurial value that it may have. Its presence is 

 definitely advantageous in extreme soils that is, 

 heavy clays or light sands and well worth con- 

 sideration. 



It should be noted carefully that when humogen is 

 applied to bulbs and corms only i part of humogen 

 to 20 parts of soil should be used. In all experi- 

 ments carried out with monocotyledons it has been 

 found that one-half of the dressing required for 

 ordinary plants is sufficient. 



In considering the application of humogen to 

 agricultural conditions it is not possible to speak as 

 yet with the same degree of certainty as it is in 

 horticultural and glass work. The present year, 

 for instance, with its seven weeks of continuous 

 drought, has resulted in many field experiments 

 giving, so far as can be seen at present, nega-
