Synopsis
Fertilizer Aftermath offers clear findings on how fertilizers, lime, and soil amendments affect long‑term soil health and farm productivity.
It presents practical observations from field plots and explains how different inputs change organic matter, acidity, and plant food contents over time. This edition details how organic matter can be built and preserved without overhauling the land, the impact of lime on yields and soil chemistry, and the complex balance between nitrogen, phosphorus, and carbon. It also covers nitrogen fixation and the role of acid phosphate and potash in sustaining fertility, with guidance drawn from real-world experiments.
- How organic matter, acidity, and yield respond to different fertilizer strategies
- The effects of lime alone versus lime with manure or fertilizer
- Patterns of nitrogen balance and potential nitrogen fixation in soils
- Practical insights for managing lime requirements and soil fertility over time

Paperback. Etat : New. Print on Demand. This book examines the long-term impact of fertilizers on soil composition, crop yield, and the effectiveness of various treatments over 15 years. The author analyzed soil samples from a series of test plots that had received different combinations of fertilizers, including nitrogen, phosphorus, potassium, and lime, and compared them to untreated control plots. The results demonstrate that nitrogen fixation occurred in plots treated with acid phosphate and/or sulfate of potash, with rates varying from 20 to 78 pounds per acre per year. Notably, phosphorus applied to the soil remained fixed in the top 6 3/4 inches, indicating that it was not lost through drainage. Furthermore, the use of fertilizers, particularly complete fertilizers and manure, led to increased organic matter content and decreased soil acidity. In contrast, excessive lime application was found to deplete nitrogen, phosphorus, and organic matter. These findings suggest that judicious fertilizer use can enhance soil health, promote crop growth, and potentially reduce the need for lime in acidic soils. This book offers valuable insights for farmers, soil scientists, and anyone interested in sustainable agricultural practices and soil management strategies.
