4 Experiments with Humogen. 



SERIES I. 



Two pots each of Dwarf French Beans, Potatoes, and Red Clover were 

 grown in each of the 14 sections described below a total of 84 pots. 



General view of the Trials in Series I. 



The following table shows the composition of the potting material used 

 in the various sections. 



1 Control Plain soil. 



Added to soil. 



2 Complete Fertiliser (2 ozs. per pot) 



3 Farmyard Manure 10%. 



4 Farmyard Manure 20%. 



5 Farmyard Manure 10%, and Complete Fertiliser (i oz. per pot). 



6 Humogen 5%. 



7 Humogen 10%. 



8 Humogen 20%. 



9 Humogen 30%. 



10 Humogen 5%, and Farmyard Manure 10%. 



11 Humogen 10%, and Complete Fertiliser (i oz. per pot). 



12 Common Burning Peat 20%. 



13 Rito 10%. 



14 Rito 20%. 



Pots of the 10-inch size were used, and the manures and other dressings 

 were incorporated with the soil before sowing or planting. A plentiful supply 

 of water was given, as required. 



In the trials with Humogen, the plants gave the appearance of being 

 scorched and were stunted in growth (see sections 6 to 9 in the centre of the 

 illustration above). This feature may be still more clearly seen in the 

 photographs of the several sections, reproduced on the following page. 



The tabulated results, and some observations recorded during the growing 

 period, are given on pages 6 to 8.
