Now, the more fertile a soil is, that is, the more soluble plant- food it contains, the more material will be dissolved in the soil- water, and as a result the more slowly will evaporation take place.- "Dry-Farming", John A. Widtsoe.
Thus we see that in the solid and fluid excrements of man and animals, all the nitrogen- in short, all the constituent ingredients of the consumed food, soluble and insoluble, are returned; and as food is primarily derived from the fields, we possess in those excrements all the ingredients which we have taken from it in the form of seeds, roots, or herbs.- "Familiar Letters of Chemistry", Justus Liebig.
