Observations made during both years tend to the same conclusion that the distribution of nitrates through the sub-soil is determined by climatic4 SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH factors and the physical character of the sub-soil layers and that the growth of the crop in turn depends to a cosiderable extent on the distribution of nitrate.

[...] It was noticed that the percentage of fat varied from 3.0 to 7.5 in case of the two Montgomery and from 2.8 to 8.6 in the case of the two cross-bred cows and that the variation between the moring and the evening milk of the same cow was from 3.0 to 7.0.
