Best Answer


John Baptist van Helmont demonstrated in the 17th century that plant growth is primarily from water. He grew his famous willow tree for five years and weighed the soil and the plant at the beginning and at the end of five years. The soil lost just 0.06kg while the willow gained 76.8 kg. Van Helmont concluded that plants grew mostly from water.
