I searched the public library for a short book that would give the key to this puzzle, but I did not find what I wanted.. There were indeed some good books by good scientists and they are in my list of references at the end of this book, but they each dealt with only a part of the problem. For example, books that described the soil bacteria made no mention of landlords.. The popular books on agriculture included novels, biographies, and essays, but these all avoided technical details, and it is difficult to state or solve a practical problem without setting it against a background of details.
Because I found no one book I had to wrestle out the problem for myself, from various books and with the help of such experience of the land as a man may gain in his leisure. This, then, is a short book on the central problem of agriculture, that is the quality of soil.
