grains of liquid, or 2*5632 grains from trie entire solution used in 

 the experiment, and absorbed by 3500 grains of soil ; or 1000 

 grains of soil absorbed *7323 grains of ammonia, in addition to 

 *804 grains of ammonia absorbed in the 1st Experiment, thus 

 giving a total of 1*5363 grains of ammonia in both trials. 



Third Experiment (Heavy Clay Soil). 



Ammonia. 

 Grains. 



Quantity of ammonia left in bottle *846 



,, ,, added in fresh solution .. .. 9*442 



10-288 



1000 grains of mixed solution contained *515 



After contact with soil 1000 grains of solution contained *450 



065 



Therefore *065 grains were removed from every 1000 grains of 

 liquid, or 1*294 grains from the entire solution, and absorbed by 



3500 grains of Soil. Ammonia. 



Grains. 



1000 grains thus absorbed in the 2nd Experiment .. -3697 

 And in the 1st Experiment *7543 



Or in both Experiments 1-1240 



Fourth Experiment (Sterile Sandy Soil). 



Ammonia. 

 Grains. 



Quantity of ammonia left in bottle -414 



,, ,, added in fresh solution .. .. 9*442 



9*856 



For 1000 grains of mixed solution there was *562 



And after contact with soil '431 



131 



Thus "131 grains were removed from every 1000 grains of 

 solution, or 2*290 grains from the entire solution, and taken up by 

 3500 grains of soil. 



Ammonia. 

 Grains. 



1000 grains of soil, therefore, absorbed in 2nd Experiment '654 

 And in 1st Experiment *868 



Or in both Experiments 1*522 



Fifth Experiment (Pasture Land). 



Ammonia. 

 Grains. 



Quantity of ammonia left in bottle *926 



added in fresh solution 9*422 



10-348 



1000 grains of mixed solution contained *546 



And after contact with the soil *370
