Botany Science Fair Project

Organic vs. Inorganic Fertilizers

Medium
Organic vs. Inorganic Fertilizers | Science Fair Projects | STEM Projects
Are organic or inorganic fertilizers more effective? To find out, we'll compare the growth of plants fertilized with organic and inorganic fertilizers over two weeks.

Hypothesis

The hypothesis is that organic fertilizer will produce the fastest growth results.

Method & Materials

You will fill six peat cups with potting soil and grass seed, then water them every other day. Three cups will be fertilized with organic fertilizer and three with inorganic fertilizer.
You will need six peat cups, potting soil, grass seed, organic fertilizer, and inorganic fertilizer.

Results

The results showed that the inorganic fertilizer produced the fastest growth results, on average 1.2 mm taller than the organic fertilizer in two weeks.

Why do this project?

This science project is interesting because it shows how different types of fertilizers can affect the growth of plants.

Also Consider

Variations to consider include testing different types of organic and inorganic fertilizers, or testing the growth of different types of plants.
