I 7 4 THE SPIRIT OF THE SOIL 



grown under glass, the ground should be watered 

 well after application. 



In the case of pot plants generally, including 

 cucumbers, melons, and marrows, the compost 

 suitable for the requirements of the plants should be 

 used, omitting leaf mould. The best results so far 

 have been obtained by using i part of humogen to 

 9 parts of compost. 



For grass, lawns, golf-greens, and tennis-courts, 

 humogen should be applied in February as a 

 top - dressing, at the rate of 4 ounces to the 

 square yard, or approximately 10 cwt. to the 

 acre. 



A valuable liquid stimulant can be obtained by 

 soaking a pint of humogen in 2 gallons of warm 

 water, allowing it to stand overnight, and using the 

 liquid undiluted when watering. Such a liquid has 

 all the advantages of a Nitrogen stimulant without 

 the drawbacks. In applying the liquid extract of 

 humogen the grower is enriching the soil with 

 bacteria, which will continue yielding available 

 Nitrogen and auximones. By this means the plant 

 is developed completely, and there is not simply a 

 stimulation of leaf development as occurs with 

 nitrate stimulants. There is very seldom any danger 

 of the plant being injured by even extreme strength 

 of the liquid. It can be given as dark coloured as 

 black coffee, and in that concentration it is/most 

 effective if a powerful stimulant is required. As is 

 the case when the humogen is applied in other 

 forms, free and perfectly balanced growth is pro. 

 moted.
