Explore We have learned that agronomy is a science and a technology that also uses plants in agriculture in different ways. It is a career, both humanitarian and scientific. We also learned that soil has a lot of nutrients that help humans gain energy, especially when it comes to the vegetables that us humans eat. Soil also helps plants grow due to the nutrients within said soil. We also learned that climate can really affect how a plant grows, due to its extreme temperatures, decreased water availability and changes in soil.
Research Question How does fertilizer affect plant growth?
Predictions Fertilizer adds nutrients to plants causing them to grow in a faster rate than the plants without fertilizer.
Experimental Design Conduct background on what type of fertilizer, soil, and plants we are going to use Fill 2 pots with soil Plant 2 of the same plants Apply fertilizer to one and not the other Place in window sill with the same amount of sunlight Apply frequently and with the same amount Observe the rate of growth over time Record data in a notebook Determine if fertilizer greatly affects plant growth
Conclusion The plant that contained fertilizer grew faster and healthier than the one without fertilizer. Possible explanations are that, since fertilizer is filled with many nutrients like potassium, phosphorus, and nitrogen it allows the plants to really take in nutrients and grow faster. Since without these nutrients, it takes longer for a plant to develop though it can possibly just be as healthy as the plant with fertilizer. The data supports our claim since the one with fertilizer grew rapidly faster than the plant that did not,. Future experiments could require actual crops other than a few plants and could be shown differently and being able to further tell how fertilizer affects plant growth.
