MANURES AND FERTILIZERS. 61 
matter as did the manured plat, while the un- 
manured plat gave about three-fifths that of 
the manured. A liberal manuring increased 
the albuminoids in the crop; in the kernels 
there was a marked increase in the protein 
and nitrogen-free extract. 
At the Missouri station barn-yard manure 
(solid and liquid together) increased the yield.* 
At the Texas station, on poor, shallow, upland 
“post oak” subsoil of stiff clay, cow manure 
gave most profitable returns, though bone meal 
produced the largest increase in yield.+ 
Artificial fertilizers have been largely used 
with profit in this country, notably South and 
East. It would be useless, however, to recom- 
mend to the farmer the use of anything but a 
complete fertilizer for corn, not knowing the 
soil conditions or the adaptability of a given 
farm to this cereal. If the soil is deficient in 
nitrogen, potash or phosphoric acid, the best 
way to do witl be to try some special fertilizers 
contain.ng these ingredients, and so determine 
just what the land needs most. It will be safe, 
however, unless in exceptional circumstances, 
to use plenty of stable manure for the cornfield 
and then supplement this with a dressing of 
fertilizer.
