Plants and Fertilizers

Without research and the use of fertilizers, today's human population could not survive. Limited amounts of nutrients in the soil will be consumed by plants in just a few years. We need to feed the soil with nutrients to be able to use it again as farm land. 

Nutrients for soil are called fertilizers. These are what plants need to grow, but what are the materials that plants need. How many types of fertilizers exist? Where do they come from or how are they made? Is any fertilizer good for any plant? 

 Project description:
In this project you will study the effect of fertilizers on plants. You will also compare organic fertilizers with synthetic fertilizers.

A collection of seashells that students may use as display or for research is available at online store. Since seashells are made of natural calcium carbonate, many students use it to test the effect of acids on it or use it as a substitution for bone or tooth for simplified experiments.
