This resource provides an in-depth exploration of soil nutrient analysis specifically related to agricultural practices at Green Valley Farm, which specializes in corn production. The learning objective is for students to analyze soil nutrient test data to identify limiting factors affecting plant growth, as well as to explain how soil nutrient levels influence ecosystem health and nutrient cycling. The document presents a real-world scenario that emphasizes the importance of balanced fertilizer ratios of Nitrogen, Phosphorus, and Potassium, detailing the consequences of both excessive and inadequate nutrient levels. It includes steps for data collection and analysis, prompting students to calculate deviations, identify limiting nutrients, and make connections to local ecosystems, such as a nearby lily pond. Additionally, it encourages discussion around feedback loops in soil nutrient management and potential environmental impacts, culminating in a synthesis of how nutrient deficiencies can affect plant health and surrounding ecosystems.
