Fertilizers and Crop Production

THIS book is the successor to the authors "Fertilizers and Crops," published in 1912. The intervening years have been filled with the ever-increasing activity of agricultural research workers in the study of problems relating to plant nutrition and crop production, covering all of the various phases, chemical, physical, and biological. Many definite facts have thus been added to our knowledge.
