Which book did Justus von Liebig publish about agriculture and physiology in 1840?

In 1840, Justus von Liebig published the influential work Die organische Chemie in ihrer Anwendung auf Agricultur und Physiologie (translated as Chemistry in Its Applications to Agriculture and Physiology).1

This publication marked a significant shift in his career, as he began applying organic chemistry to investigate living processes. In the book, Liebig argued that a rational system of agriculture must be based on scientific principles, asserting that chemists were essential for determining the best methods for plant nutrition and soil analysis. While some of his specific theories regarding nitrogen sources were later proven incorrect, the work is credited with launching the systematic development of the agricultural sciences.12
