140 EXPERIMENT STATION RECORD. 



Field experiments at Grignon, France, from 1890 to 1893, J. 



DuroNT {Ann. Agron., 20 (/'S'Vi), ^o. .V, j>i). Vi7-lt>ii ; X<>. o, pp. 220- 

 247). — The very favorable residual efiect of stable iiiaiinre is empha- 

 sized by the results of these experiments, Neither direct ap])lications 

 of stable nuinure nor of nitrate of soda gave yields of wheat equal to 

 those secured where stable manure had been applied to preceding crops. 



Soluble phosphates were especially favorable to the growth of wheat 

 on exhausted soil. However, they exercised no such advantageous 

 influence on oats, probably, the author suggests, because oats with a 

 stronger feeding power were able to utilize dilticultly soluble phos- 

 I)hates in the soil and could thus dispense with applications of soluble 

 phospliates which on exhausted soil were necessary for wheat. 



Soluble phosphates were not specially beneficial to clover, the growth 

 of which was chiefly dependent on the amount of organic matter accu- 

 mulated in the soil as the result of previous applications of stable 

 manure. 



In the rotation adopted at the station clover was sown with oats, and 

 succeeded best when sown with the early varieties. Experiments in 

 manuring hemp were conducted, but this croj) did not succeed. 



Even in the fourth year, after the sod of a temporary meadow was 

 jdowed under, there was apparently an injurious effect on the wheat 

 crop, but none on the oat crop. A drought oc(;urring in April and 

 May injured the crop of oats more than the crop of wheat, due doubt- 

 less to the fact that the roots of wheat penetrated the soil to a depth 

 of 70 in., while the roots of oats reached to only 44 in. 



The lodging of oats was less injurious than the lodging of wheat 

 occurring at the same time.
