The Effects of Different Fertilizers on Plants Sean HazlettCentral Catholic High School Grade 9

ProblemChemical fertilizers:H arm the environmentUsed widelyPlant fertilizers"ingredients“ - enhance plant growth C ompetition T his experiment : T wo all-purpose fertilizers - which product works the best Looking for n oticeable effect Is there a better fertilizer that people can use that is less harmful to the environment or is no fertilizer the best fertilizer?

Purpose What fertilizer works best (seedlings):ChemicalOrganic No fertilizerEffects of fertilizer on seedlings

Miracle-Gro Liquid All Purpose Plant Food Fertilizer Light, odorless, transparent green (concentrated) Easy and pleasant “All purpose plant food” “Feeds all types of plants instantly” Application: seven to fourteen days Mix with water Nitrogen, phosphorus, and potassium “ The three most important nutrients the plants need” - Miracle-Gro

Alaska Organic Fish Fertilizer Unpleasant odor and colorationBenefits: “Won’t burn” plants“Great for all indoor and outdoor plants”Fish fertilizer – used for centuries N itrogen, phosphate, and potash

Pumpkin SquashCucurbita pepo varietyNorth America Came from Mexico F ood , decoration , and recreation Weigh 6 to 75 lbs.

SquashScientific Name: Cucurbita Native to Americas Europe - discovered Place of Origin - Andes and Mesoamerica F ive (common) species - squash F ruit and seeds (edible) Utensils, storage containers, decoration, etc. Contains: vitamin A, vitamin C, dietary fiber, niacin, folic acid, and iron; free of cholesterol.

Cucumber G ourd family G row on vines T hree main varieties: slicing, pickling, and burplessFrom Southern AsiaWidespread today Found on most continents D esired and sold on global markets

Previous Studies Liquid fertilizer :Gives greatest release of nutrientsReleases nutrients fastestR esult: grow most quickly and healthy Powdered and solid fertilizers – slower Easiest to apply because:Mixed with water Applied - top of the soil

HypothesesNull Hypothesis Fertilizer will not increase plant growth. Alternative Hypothesis Fertilizer will improve the growth of the tested plants.

Materials Miracle-Gro All Purpose Plant FoodAlaska Fish Fertilizer pumpkin seeds s quash seeds c ucumber seeds okra seeds (back up group)peat planting cups styrofoam cups Jiffy Natural and Organic Seed Starting Mix p lastic food wrap various colored tape rolls p lant sticks and clips c amera (optional) 5-foot tall adjustable lighting stand 4-foot grow lights H ydrofoam 4-foot fluorescent grow light fixture 2-in-1 s oil moisture / light tester t hermometer / humidity gauge Ohaus Pioneer Scale (measures down to .0001 grams) plastic weigh boats (6) 60 mL syringe Sharpie pen scissors journal / notebook and pen de-chlorinated water glass terrarium ruler / tape measureplastic folding table 5 or more 2-gallon buckets printer paper large plastic sheet

ProcedureAssembled light and light fixture, table, aquarium, and positioned light fixture (light should be one inch above the top of aquarium) F illed all peat planting cups (36) with Jiffy Natural and Organic Seed Starting Mix M ade small indentation for seeds in the top soil in the peat cups for the seeds (1/2 to 1/4 inch deep [ 2x the width of the seed]) Cut off tops of 36 Styrofoam cups (1 inch from bottom) (keep bottoms only), labeled each (1 to 36), paired with a peat pot, organized each according to the chart (see Diagram 1) I nserted respective seed , watered plants (10 mL each) [repeated every 2 days] P laced plastic wrap on top of aquarium to retain moisture (removed when lighting switched to 12-hour intervals)

Procedure (Continued)Monitored temperature and humidity to keep it consistent throughout experimentDay 14 - began fertilization - mixed with one gallon of water, applied to plants (10 mL) every two weeks Day 41 – removed plants P owered on Ohaus Pioneer Scale, blanked scale, cut plants at dirt level, removed soil from both sections of plant, took 2 measurements (wet and dry), and quantified data

Analysis / Conclusion Based on this experiment: Fertilizer did not have a direct effect on seedlings and their early developmentNeither organic or Miracle-Gro fertilizer appeared to have a significan t benefit P-Value was far above the 0.05 standardThe null hypothesis is accepted Observations F ertilizer caused the seedlings to grow quickly and spindly L eaves showed slight traces of yellow - too many nutrients Hypothesis Purpose Experiment Results Conclusion

Limitations & Extensions Limitations Too short of a growing cycle for the plants to properly mature.Not a “natural” germination / growing periodT oo small of a seed sample and too few replications D ifficulty in removing soil from the plants’ roots in biomass measurement Extensions Experiment is only preliminary Add more seed variety , replicates , and time Add light and distance from light source – new variable
