Soils. 366 HOW THE NEEDS OF SOILS MAY BE DETERMINED Points to Observe.—In making liming tests, best contrasts in results can be secured when a definite line is made between the "limed'' and "no lime'' areas. To accomplish this, the west portion of a field should be limed when the wind blows from the east, or the east portion when the wind blows from the west. When the limed plot extends through a field, the windward border of the plot, at the time the lime is applied, should be selected

When the limed plot extends through a field, the windward border of the plot, at the time the lime is applied, should be selected for the best contrasts. The same point should be observed in applying certain fertilizers broadcast. _ Sometimes when two or more adjacent plots are to be fertilized differently, it becomes necessary to mix certain of the fertilizers.

In such tests it is usually best to apply the fertilizers by hand, and then mix them thoroughly with the soil by disking or "; Avoid the laying out of test plots adjoining and parallel to fences. Extend them into or through the field away from fences. Long strips are better than square plots. _^^^^'' \ Observing the difference in growth on the various plots is not sufficient in determining the final and comparative results. It is always best to obtain the results by weighing the whole crop and determining the actual yields. When it is not convenient to harvest each plot separately, the crop on an average square rod on each plot may be properly harvested, and results calculated to acre Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Weir, Wilbert Walter, 1882-.
