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.

∙ 12y agoVon Helmont did not discover photosynthesis, but his famous experiment with the willow tree planted in a measured fixed amount of soil over several years gave a very good hint for others to conclude.
von Helmont found that the tree gathered weight by being nourished with water, but the weight gain was not coming from the soil the tree was planted in, but for some parts of it from the water used for irrigation. von Helmont concluded that components from air must have played a part in the the weight gain, but was not able to prove that it was carbon dioxide in the air that formed the essential part of the synthesis of wood matter and he did not discover the role that sunlight plyes in the photosynthesis - later others did.

Which scientist concluded that most of a growing plants mass comes from water?
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)
How fair was van helmont experiment?
yes, it was partially fair becaues he only proved that 'water' was basic element but soil and air was also an basic element.
