Jan van Helmont
To test his hypothesis
He grew a willow tree in a carefully weighed amount of soil. He noticed that little of the soil was consumed, but that the weight of the tree greatly increased. He concluded that the extra weight came from the water. His willow tree experiment was one of the first to use quantitative measurements. Van Helmont wanted to understand digestion chemically, believed all substances could be reduced to air and water, and thought that acid/base reactions were fundamental.
Jan Van Helmont. in his 5-year experiment he planted a seedling in soil and watered it. it grew to a small treegaining 75kg. mass of soil didn't change. since water was all he added, he concluded it was from the water. - from Prentice Hall Texas Biology Book (9th grade)
yes, it was partially fair becaues he only proved that 'water' was basic element but soil and air was also an basic element.
