Saplin
1. In the 17th century, Jan van Helmont performed an
experiment to determine how much of the mass gained by a
plant came from soil. He grew a willow tree for five years,
weighing the soil before and after. The soil lost 0.06 kg of
mass, while the tree gained 74.53 kg. What inputs needed by
plants were not accounted for in this experiment?
