Grow algae in several concentrations of fertilizer and observe its effect on algal growth. Phosphate-containing chemicals deliver the essential element phosphorus to plants in a readily absorbable form. Using your graduated cylinder, place 400 mL of pond water into the cup labeled. What is your enthusiasm for science after doing your project? A soluble substance, nitrogen soaks deeply into the soil after a rainstorm or after irrigation, reaching ground water and nearby wells. Find information from Penn State Extension about agronomic crops. To obtain quantitative measurements of the algae growth, consider the methods in this Science Buddies science fair project: Design a procedure using a single species of algae and precise amounts of nitrates and phosphates. Place 200 mL of pond water into the remaining cups. Manage pests, weeds and diseases, and improve soil quality. Nitrogen in the form of nitrates works very well as a plant fertilizer and is produced in large quantities for this purpose. Have an adult come along to help. Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. deepesh32 said: Place the algae cultures in a spot indoors that is well-lit during daylight hours. Live algae and nitrate- and phosphate-containing chemicals can be ordered from science supply companies, such as. It is abundant, multivalent and nonmetallic.Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S 8.Elemental sulfur is a bright yellow, crystalline solid at room temperature. Feel free to alter the steps or materials in the procedure, just make sure you keep good notes. Therefore, it is important to consider means to prevent or reduce the amount of fertilizer that finds its way into natural bodies of fresh water when considering ways to deliver fertilizer to crops and lawns. Phosphorus is also often present in fertilizers in the form of phosphate. Moss is Boss: Using Plants to Determine Direction. In the soil, too much nitrogen also creates an imbalance of nutrients that causes a depletion of other important minerals such as calcium, phosphorus and magnesium.
