Title: What Plant Fertilizer Work The Best On Plant Growth

Abstract: We took four plants and gave three of them three different types of fertilizer and gave one no fertilizer. We gave them the same amount of water and sunlight. Then after two weeks of growing the plants we went to see how much each one grew in that two week span. We would then find the results and make our data table and graph.

Purpose: The purpose of this experiment is to see which plant fertilizer works the best on plant growth. This will show us what fertilizer works best on plant growth. We thought that since we had to do a test on a living thing that this was an appropriate experiment to do. Plants are a perfect thing to experiment in a test like this. We will take three different fertilizers, with different combinations to see what plant fertilizer works best. According to Garden Counselor Lawn Care fertilizer bags have three numbers on them. The first number is for Nitrogen, the second is for Phosphorous, and the third is for Potassium. These are the total percentage of the ingredients bag.(How Can Fertilizer Numbers Help You Pick The Right Lawn Fertilizer). According to Earth-friendly Products for home,The three main nutrients that have been identified as absolutely necessary for plants are nitrogen (N), phosphorus (P) and potassium (K) (Earth, 2012). These three are also known as macro nutrients and are the source of the three numbers commonly found on organic fertilizer labels. 21-7-14 is Big - Small - Medium, 1-3-3 is Big - Small - Small, 6-20-20 is Small - Big - Big, 21-0-0 is Big - Zero - Zero. According to How Stuff Works, If any of the macro-nutrients are missing or hard to obtain from the soil, this will limit the growth rate for the plant. These are examples of the three numbers in different order. So these are all different fertilizers. (How Can Fertilizer Numbers Help You Pick the Right Lawn Fertilizer).In order for a plant to grow and thrive, it needs a number of different chemical elements. The most important are:Carbon, hydrogen and oxygen - Available from air and water and therefore in plentiful supply. (What is fertilizer and why do plants need it) This will be a good experiment on plants with fertilizers.

combinations: If we give the same plant different types of fertilizer with different combinations, then the fertilizers with the smaller combinations will work the best.

Materials: 3 different fertilizers, 3 plants, sunlight, water, 10 mil of water per plant every day.

Procedure: We will take three different types of fertilizer, with different combinations. For example, probably big-small-medium, big-small-small, and small-big-big. Then we will put those three different fertilizers in four of the same kind of plant.(One will be getting no fertilizer). We will then give them 10 mil of water, and give them sunlight for two weeks. We will then measure the plants. From those plants with different fertilizers, we will see which fertilizer works the best and which plant grows the most.

Data:


 * Plant/Combo || Growth(in.) ||
 * Plant 1/Big || 1.5 ||
 * Plant 2/Small || 1.7 ||
 * Plant 3/Medium || 2.3 ||
 * Plant 4/ None || 2.6 ||



Analysis: As you can see in my graph the plant that we gave no fertilizer grew the most. The others came close, but plant 4 was the biggest at 2.6 inches in two weeks of growth. This shows us that maybe it is best if you give a plant just a little fertilizer, not a lot. The medium sized numbers on the fertilizers worked the best of all fertilizers. growing to 2.3 inches after two weeks of growth. The big numbers was the least efficient, growing only 1.5 inches after two weeks of growth. The small number fertilizers was right in the middle at 1.7 inches of growth after two weeks. This gives you something to think about, maybe the plants don't need as much fertilizer as we think they do. We grew our plants for two weeks and these were the results that we came up with.

Conclusion:Our original hypothesis stated: If we give the same plant different types of fertilizer with different combinations, then the one with the small numbers will work the best. Our new hypothesis is If you gibe a plant very limited fertilizer, than it will grow the largest. We rejected our hypothesis. In our experiment, we found that the plant with no fertilizer grew the most. This shows that maybe all plants don't need fertilizer.

Limitations: Three things that went wrong were, there wasn't an equal amount of sunlight, Some got more fertilizer than the others, and some got more soil and dirt than the others. We could have put the plants on a window ledge to get sunlight. We could have put equal amount of fertilizer in the cup for the plants. We could have measured the soil and dirt out instead of just scoop it in. Our new hypothesis states: If we give one plant no fertilizer, then it will grow the most. Our new hypothesis is If you gibe a plant very limited fertilizer, than it will grow the largest
