Unlock the mystery of nitrogen in crops with Rothamsted’s long-term experiments

Discover how different plants store and use nitrogen, and what this means for rotating crops and managing soil fertility for better yields.

This edition distills a century of field-scale observations on how legumes, cereals, and root crops perform when grown without external nitrogen inputs. It explains why leguminous crops can outproduce others in nitrogen content, and what this implies about soil health, nitrogen sources, and farming practices.

How different crops assimilate nitrogen when grown alone and in rotation, with and without mineral supplements
Evidence on where legume nitrogen comes from—the atmosphere, surface soil, or deeper layers
Comparisons between grassy, cruciferous, chenopodiaceous, and leguminous crops in long-term trials
Practical implications for farm rotations, soil depth, and managing nitrogen stores over decades

Ideal for readers of agricultural history and soil science, this book helps you understand the enduring value of legumes in sustainable farming.
