The Beaners

Abstract

In our study we are conducting a test with chemical and organic fertilizers.

We feel this study plays a large role in the present ever-changing ecosystem because of the widespread use of fertilizer in today's society.

Not only is fertilizer used for large crop farms, but also for the smaller private gardens.

Here are some of our questions

1. Which plant will grow faster? The plant that contains the chemical fertilizer, organic fertilizer, or no fertilizer.

2. Which plant will produce more beans?

3. Which plant grows taller?

4. Which plant seems healthier (greener, produces more beans, healthier leaves)?

Our Hypothesis

We predict that the chemical fertilizer will have a higher crop yield than organic or no fertilizer.

We also predict that the chemical fertilizer will produce a healthier bean plant.

Relevance

The results from our experiment will hopefully reflect a larger scale of plant growth and cultivation, such as a farming community.

The Bean Daddies, as they were called, experimented with chemical and organic soil and different types of water. Their results showed that organically grown beans are not only healthier and produce more leaves but they require less water.

Relevance (cont.)

Our project has pertinence, on a potentially global scale, to farming and agricultural efficiency and health. The information that we will gather by the end of the project will prove the effectiveness of a popular chemical fertilizer and a popular organic fertilizer in the healthiness and size of bean plants.

Materials

In our study three flats of beans will be monitored. Each flat contains 24 bean plants.

One flat will be fertilized with a chemical fertilizer (miracle grow)

Another flat will be fertilized with an organic fertilizer (horse manure)

The last flat will be the control group, where no additional fertilizer will be added.

Method

After the plants had been planted for a month, we then applied the fertilizers. On this day we made our first observations.

We recorded the height (in millimeters), width (in millimeters), health, color, and bean count of each plant. The health will be rated on a scale from one to seven; seven being the healthiest, one the weakest.

This information is recorded on a weekly basis

So what plants yielded the best results?

The organic plants?

The chemical plants?

Or the control plants?
