Beginning and development
of the agronomic sciences

Agronomic sciences are the application of biological, physical, and human sciences to agriculture; their development is linked with rigorous experimentation. In the 19th century, scientific progress in chemistry, biology, microbiology, mechanics, influenced the development of agricultural practices.

Little by little, a scientific way of thinking is born and developed, particularly in 3 fields of agronomy:

Nutrition (def.) (production and increasing use of fertilizers)

BoutonHygiene (def.) (protection of crops from diseases and insects) 

Simultaneously, agricultural activities are systematically mechanized.
