Johan Gottschalk Wallerius

[1][2] Johan Gottschalk entered Uppsala University in 1725, and graduated as magister in 1731 after studies of mathematics, physics and medicine.

[4] Wallerius is regarded as the founder of agricultural chemistry, mainly based on the significance of his widely disseminated work Agriculturae fundamenta chemica (1761, published in Swedish the same year as Åkerbrukets chemiska grunder and later translated into many other languages).

[5] He published several other studies on chemical, mineralogical and geological subjects and used his own farm Hagelstena in Alsike (south of Uppsala) as an experimental field.

He spent his early retirement from the University due to poor health applying the principles of chemistry as a way to improve agriculture in his own farm, and published some of his findings in Rön, rörande landtbruket.
