Excerpt from Investigations in Soil Fertility In a broad sense a fertile soil has been taken to mean one which usually produces a large crop. The yield would thus be a measure of fertility. The yield, however, 18 dependent not only upon the condition and properties of the soil, but upon the climatic conditions as well. In a more restricted sense some agricultural investigators have endeavored to approximate the fertility of soils from the results of chemical analyses, recognizing that the yield of crops is not a measure of fertility, as the yield is dependent upon the kind of, crops adapted to a particular Soil, upon the texture of thesoil itself, present mechan ical conditions drainage conditions, suitable climatic conditions, and efficient methods of cultivation. It is in a similarly restricted sense that the term will be used in this bulletin; that is to say, fertility is the inherent power of a soil to produce and support a satisfactory crop under favorable climatic conditions and suitable cultivation. To what this inherent power may be due, whether to definite amounts of plant food or to other causes, need not be more specifically stated at this point. Using fertility in this restricted sense, the conditions of climate, drainage, and cultivation, being more or less incidental and variable, would affect the yield but not necessarily the fertility of a soil.
