Ideas for Plant and Soil related Science Fair Projects
Plant and soil sciences or agriculture doesn't have
its own category in science fairs, but it is a part of many of the official categories like Chemistry, Physics, etc. This is because agriculture is a applied
science. Here are a few basic ideas for agricultural science projects. Use
these ideas as a jumping-off place for coming up with your own cutting edge
research project with great ideas.
1.
How
do different treatments change how fast seeds sprout?
You can find out how quickly seeds sprout under different temperatures, or after being soaked for different times or in different liquids. Or, see how one kind of treatment affects different types of seeds.

2.
What
effect does seed size have on how well a crop like oats or wheat grows?
Pick out groups of seeds all of the same size. Be sure and measure the seeds before you plant them. You can define success a number of ways: how many seeds sprout, how fast the plants grow, how tall the plants get, etc.

3.
Which
way is up?
Many seeds and bulbs have a definite top and bottom. What happens if you plant them upside down or sideways? Will they still grow? Will it take longer for leaves to start showing up? You may have to dig the bulbs up to measure root growth.

4.
What
happens if you change a seed's direction once it starts to sprout?
Many seeds like beans can be sprouted in moist cotton or paper towels. What happens if you turn the seed 90 or 180 degrees from right-side-up every few days after it sprouts?

5. Does the amount of room a plant has for roots make a
difference in how big a plant will grow regardless of how much fertilizer the
plant is given?
Plant seeds in a variety of different-sized containers using vermiculite or other soil-less material, so you will be able to give each plant a measured amount of fertilizer. Or plant a number of plants in the same size containers and vary the amount of fertilizer and see what happens. Be sure to use small enough containers so that root growth really will be constricted.
