What Type of Soil is the Best For Growing SeedsAddison Grace MaxwellCarrollton Junior High School Table of ContentsContents?Table of Contents 2Introduction 3Methodology 4Results 5Conclusions 6References 7? IntroductionI would like to determine what is the best type of soil for growing seeds.  So this is the question I will try to answer in my science experiment.  There are many different types of soil available to choose from.  Without the ability to grow seeds we will not have plants, vegetables or flowers.  Without plants we will not have fresh air to breath so seeds are very important.  Often people grow their own vegetables to survive.  Without the ability to take a seed and grow it into a healthy plant that produces vegetables, many people would not be able to survive.   My goal is to determine which type of soil grows the healthiest plant.  I will also determine which type of soil produces a plant in the least amount of time and then determine if that type of soil is able to sustain the plant and allow it to grow into a prosperous plant.   My hypothesis is yard dirt will grow the best type of seed.  This is the most natural type of soil and I think it will provide the best environment for the seed to grow.  I will compare yard dirt, seed-starting soil mix, potting soil, peat moss and sand to determine which is the best type of soil for growing a seed.  I will take marigold seeds and plant them in each type of soil.  I will monitor the soil to determine which type produces a plant first and document each plant’s growth.  I will also document the longevity of each of the plants to help determine the ability of the soil to sustain the plant.  According to Heilig (2013) there is little difference between seed-starting mix and potting soil. Based on my research, gardeners often find the type of soil they like best and use that type instead of trying out various types.   According to www.bettervegetablegardening.com their are 4 or 5 basic health and growth needs a potting soil has to be able to supply a plant with to be successful.  These basic needs are aeration, water, nutrients, support, and light (www.bettervegetablegardening.com).  It will be interesting to determine exactly which type of soil offers the best combination of the basic needs to support a seed.   Also, there are specific types of soil that should be used for specific types of plants (www.morningchores.com).  Flowers need a different type of soil than grass.  It is important to determine the best type of soil for the specific seed you are growing.  I will be using marigold seeds, which is a flower seed, so I will need to focus on the best type of soil for growing flowers.  Seeds and plants need lots of sunlight but not much water, you don’t want to overflow the seed/plant. Too much water can cause the plant to suffocate and not get the oxygen it needs to survives, basically drowning your plant so you need to be careful.  The soil you use needs to be moist or damp. My independent variable for this experiment is the seeds because they do not change. My dependent variable is the soil because I will be using all different types of soil.  I will use the same amount of water for each container of soil and provide the same amount of light.  MethodologyTo start this experiment, I will need potting soil, yard dirt, seed-starting soil mix, sand, peat moss, marigold seeds and containers to hold the dirt and seeds. The first thing you need to do is label each container with the type of soil it will contain.  Fill each container about three quarters of the way full with the specific soil and put five to seven marigold seeds in the soil.    The seeds need to be well covered by the dirt and spaced about 1 inch apart.  Once the seeds are planted I will put enough water in each container to make the soil damp.  I will cover each container with plastic wrap for the first week to provide a warm growing environment.  The containers are going to be placed under an artificial light source because I do not have a warm and sunny place to keep the plants in the winter.  After the first week I will remove the plastic wrap so the plants do not get too warm. I will document the plants height on a daily basis once they begin to break through the soil.  I will document which type of soil produced the first plants and continue to monitor the growth of the plants to determine the best type of soil to produce a healthy plant.  Results The above chart and graph show the growth of each seed in inches.  The growth was measured on a daily basis.  There was no growth observed in the first two days of the experiment.  On day three, there was growth in the seed soil.  This was the first growth I had seen.  On day four, there was growth in both sand, yard dirt, and seed soil.  The very last soil to produce a plant was the plain soil.  ConclusionsI found out that seed soil and yard dirt were the best but the seed soil was the first one to show up.  My hypothesis was somewhat correct.  The yard dirt did produce seeds just not as quickly as the sed soil.  The seeds grew in the sand at first but after a week, the seeds growing in the sand began to die. The sand was able to hold heat and water to help the seed grow at first but the sand did not the nutrients to maintain the plant.  The last soil to produce a plant was the plain soil. I was surprised that the plain soil was the last to produce a plant because I thought it would have enough nutrients to help the seed grow.  I have conclude that the best soil to go with is seed soil or just yard dirt.   The next time I want to grow a plant from a seed I will use a mix of seed soil and yard dirt.  From my research, I have determined that is the best combination of soil to grow seeds.  I will also share this information with anyone who would like to grow plants from seeds.  I was surprised at how well the seeds grew in the sand and also how well they grew in the yard dirt.  I was disappointed that the plants did not produce flowers.  The plants that did grow where very thin and weak.  If I could do this experiment again, I would like to do it in warmer weather where the plants could grow outside and get more sunlight.  ReferencesBibliographyHeilig.
