Volcanic Ash: The Beginning or the End? The Study of Volcanic Ash and Its Effects on Plant Germination

CSEF · 2013 Plant Biology

Sabrina C. Belen, Brandon S. Snyder · Desert High School, Edwards, Kern County

Overview

Objectives/Goals The purpose of this project was to determine what effects differing amounts of ash mixed with soil would have on the germination and growth or radishes, green beans, and pea seeds. Methods/Materials 25 green bean, 25 radish, and 25 pea seeds were individually grown in 75 red solo cups with a drainage hole in each. They were grown in 100% soil 0% ash - 100% ash 0% soil. They were watered every other day and when done growing for a certain time period were measured on # of leaves, stem and root length, # of root branches,# of sprouting seedlings, color(radishes only), and root weight. Results The data supports the hypothesis. The growth of the seedlings was greatest in the 75%soil/25% ash and the 100%soil/0% ash. Conclusions/Discussion This project concludes that not only is it possible to grow plants with ash, but that volcanic ash can actually enhance a plants' growing environment.
