Van Helmont rejected the idea that plants take food from the soil because he conducted an experiment where he showed that the increase in plant mass did not directly correlate with the amount of soil available to the plant. Instead, he concluded that plants primarily obtain their nutrients from water.

How was the way plants feed discovered?
Aristotle was a Greek scientist who thought that plants ate soil and sucked it up through their roots. Most people believed this until the 17th century. In the 17th century, a scientist called Jan van Helmont tested Aristotle's theory. He measured the masses of a small tree and some soil in a pot. He planted the tree and watered it for 5 years In van Helmont's experiment the mass of the soil did not go down much (0.06kgs/ 0.132lbs) but the mass of the tree went up a lot (74.47kg/163.834lbs). This showed that Aristotle's theory was wrong. Van Helmont suggested that the tree got all of its food from water. In 1782, Jean Senebier showed that plants need carbon dioxide gas from the air and suggested that plants only use this gas to make food. In 1804, Nicholas de Saussure did van Helmont's experiment again, but he carefully measured the amounts of carbon dioxide and water he gave to the plant. He showed that both carbon dioxide and water are needed.

Why did a review of van Helmont's work lead to the idea that air could be important in the making of food?
He worked during the years just after Paracelsus and iatrochemistry, and is ...Van Helmont is remembered today largely for his ideas on spontaneous ...For Van Helmont, air and water were the two primitive elements. Fire he explicitly denied to be an element, and earth is not one because it can be reduced to water.
