Comparing Soil Types
Easy
We're going to take soil samples from two counties and compare them to see which one is better for growing crops. We'll use the samples to determine which county has the best soil for growing crops.
Hypothesis
The hypothesis is that Yakima County will have a higher likelihood of being loam soil than in Pierce County.
Method & Materials
You will plan a trip to the county, find a city, find a place to sample soil, take a quart jar and fill it with soil, label the jar, put it in a safe place, and make a log of the soil.
You will need 8 quart jars, 8 labels, 2 shovels, and 1 journal log.
Results
The results of the experiment showed that Yakima County had all loam soil, while Pierce County had mostly sandy loam and sandy soil. This means that Yakima County has the best soil to grow crops in.
Why do this project?
This science project is interesting and unique because it helps people who farm to choose what type of soil to look for when buying property, and it helps gardeners decide which part of their property to use for growing crops.
Also Consider
Experiment variations to consider include testing the soil samples again to make sure they are correct, sampling more cities in the county, and sampling more counties from eastern and western Washington.
