Millet isotopes reveal advanced agriculture in early imperial China

Researchers make stunning discovery that could alleviate strains on food supply: 'Further increases productivity'

Conservation-minded farming techniques can improve crop yields and the ability of soil to absorb carbon, according to a recent study. Poor soil health is one of the challenges presented by conventional farming practices and a changing climate. The impacts of intensive tilling, pollution, and shifting weather patterns on soil composition pose serious risks to global food security. However, the new study offers a partial solution — and it's pretty…

Millet isotopes reveal advanced agriculture in early imperial China

A new study reveals how ancient Chinese farmers managed soil fertility and water resources over thousands of years. By analyzing carbon and nitrogen stable isotopes in millet crops, the research provides long-term isotopic evidence of farmland management practices in the Guanzhong Basin—the political heartland of early imperial China.
