Plants and Tree Growth, Where Is The Hole Under A 300 Foot Tree or Even Plants? Simple Not From Fertilizers But Air!



In what is perhaps his best-known experiment, Jean Baptist van Helmont placed a 5-pound willow in an earthen pot containing 200 pounds of dried soil, and over a five-year period he added nothing to the pot but rainwater or distilled water. After five years, he found that the tree weighed 169 pounds, while the soil had lost only 2 ounces. He concluded that 164 pounds of wood, bark and roots arose out of water only, and he had not even included the weight of the leaves that fell off every autumn. This tree was grown entirely without any fertilizer!


How can trees be so tall. And do they grow from from nutrients out the air or ground.

Why is it that we dont understand as much as we think we understand. 7 years old do better than PhDs.
