Not a nice subject to be sure, 



But plants thrive better with manure. 



MANURES 



Practically all organic manures contain ni- 

 trogen. Green weeds turned under the ground 

 form humus and humus is a storehouse for 

 nitrogen. Nitrogen is furnished in the most 

 available form, in nitrate of soda. Nitrates are 

 formed more rapidly in warm weather. Nitrate 

 is formed by the action of microscopic organ- 

 isms. All fertilizers must undergo this process 

 of nitration before they are turned into plant 

 food. 



Leguminous crops, such as field peas, 

 vetches, burr clover, etc., when turned under 

 the ground and allowed to rot, supply the soil 

 with nitrogen in addition to humus. The leg- 

 umes have the power to collect and store nitro- 

 gen, which other plants utilize as food. All 

 legumes should be turned under about the time 

 of blossoming to get the best results. Hen 

 manure should be mixed with land plaster or 

 gypsum. 



Barnyard manure should be confined in a 

 pit with a clay bottom or in a rock built tank 

 with a cement bottom or a tank built entirely
