How Plants Benefit From the Soil- Science Project Idea
Chemical analysis of plants and experiments in their culture indicate that the following ten elements are necessary for their growth: Carbon, hydrogen, oxygen, nitrogen, potassium, magnesium, calcium, iron, sulphur, and phosphorus.In our study of the making of starch and wood by plants, we have already discovered from what source the plant gets its carbon, hydrogen, and oxygen.Review and explain.All the other elements must come from the soil.
Fortunately, the soil usually contains all of these with the exception of three, in such quantities that there is not much danger of them being exhausted.The three which are likely to be lacking are nitrogen, potassium, and phosphorus.These frequently have to be added to the soil in some way.
Science Project Idea Research all the ten elements that are necessary for plant growth; Carbon, hydrogen, oxygen, nitrogen, potassium, magnesium, calcium, iron, sulphur, and phosphorus.Show where each of these elements are incorporated into the growth of the plant.
