Fertilizers with Timothy on Dunkirk Clay Loam, 287 



6. While a marked increase in hay was obtained from the use of 

 fertiUzers containing nitrogen, the small increase in the yield of oats 

 left only a small net gain and in some instances a net loss from two 

 applications. When the experiment is studied in detail it appears 

 that the proportion of nitrogen to phosphoric acid should have been 

 greater in order to get the most profitable returns. 



When muriate of potash was applied either alone or with nitrate 

 of soda there was a net gain,

 the application of nitrate of soda or other readily soluble forms of

Fio. 21. — Under conditions where fertilizers are effective, a complete fertilizer mixed in 



proper proportions will produce optimum results. 



nitrogen will become more profitable. The importance of this ex- 

 periment, however, is in emphasizing the importance of systems of 

 farm management which will bring to soils of this type in New York 

 State the largest supply of readily ava'ilable nitrogen. The use of 

 leguminous crops and the proper preservation of stable manure and 

 particularly the liquid excrement, which contains the larger part of 

 the nitrogen excreted by domestic animals, is again emphasized. 



8, No influence on the growth of timothy has been observed from 

 the use of lime, but, in other experiments on the same soil type, 

 marked results with lime have been obtained upon the growth of 

 alfalfa.
