How crops and cultivation reshape soil nitrogen—and what that means for fertility.
This nonfiction volume presents a focused study on nitrogen economy in the soil, drawing from pot experiments started in 1914. It outlines the plan, methods, and scope of the work, and compares how representative crops affect nitrogen removal and recovery in soils under control conditions. The discussion explains how cultivation and different crops influence nitrogen losses and the overall soil nitrogen balance, with attention to both cropped and fallow soils.
- A clear description of the experimental setup and measurements used to track soil nitrogen
- Comparisons across legumes and non-legumes, including notable findings on nitrogen recovery
- Observations on how cultivation practices relate to nitrogen losses and soil health
- Implications for managing soil fertility and crop uptake of nitrogen
Ideal for readers of agronomy, soil science, and anyone interested in how farming practices influence soil nutrients over time.
