Investigate to determine the best soil type and additives to use for three different crops. Make a recommendation to the farmer that takes into consideration both the crop yield and the environmental impact.
Data Collection
Using the Soil Analysis Lab Activity, you will be collecting data about crop yield and environmental impact of soil types and adjusting soil additives for three different crops.

Data Analysis
Before drawing conclusions or making a recommendation, you will need to look for
patterns and trends in the data. Write a paragraph describing the data and any patterns
or trends you see for each of the three crops.

Drawing Conclusions and Making a Recommendation
Having studied the data for patterns and trends, you should now be able to draw some
conclusions and make recommendations to the farmer about what soil and soil additives
he should use for each crop to attain the best crop yield with the lowest environmental
impact. Include the following:
● What was the best soil type for each crop?
● What were the optimum soil conditions for each crop?
● How did crop impact relate to environmental impact?
● If the farmer chooses to grow only one crop, which one would you recommend? Why?

In terms of patterns and trends, it can be seen that each crop has specific soil type and nutrient requirements that lead to optimal crop yields. The crop impact was directly related to the environmental impact, with the crops showing better yields in soils that were well-balanced and had optimal pH levels and nutrient content.
Overall, if the farmer chooses to grow only one crop, I would recommend growing soybeans. Soybeans showed consistent results in terms of soil type and nutrient requirements, and they also had a high crop yield with relatively lower environmental impact compared to corn and sunflowers. By focusing on growing soybeans, the farmer can achieve a good crop yield while also minimizing the environmental impact.
Corn:
- Optimal Soil pH: Slightly acidic (around 6.0-6.5)
- Optimal Soil Nutrients: Balanced levels of nitrogen, phosphorus, and potassium
Soybeans:
- Optimal Soil pH: Neutral (around 6.5-7.0)
- Optimal Soil Nutrients: High nitrogen content, adequate levels of phosphorus and potassium
Sunflowers:
- Optimal Soil pH: Slightly alkaline (around 7.0-7.5)
- Optimal Soil Nutrients: High levels of phosphorus, adequate nitrogen, and potassium
By maintaining these optimal pH and nutrient levels in the soil, the farmer can ensure the highest crop yield for each specific crop while also minimizing the environmental impact.
Corn:
Part 2: pH and Nutrients
Test 1: Soil pH: 6.0-6.5
Test 2: Nitrogen: 80-120 ppm
Test 3: Phosphorus: 25-35 ppm
Test 4: Potassium: 150-200 ppm
Test 5: Organic Matter: 2-3%
Soybeans:
Part 2: pH and Nutrients
Test 1: Soil pH: 6.5-7.0
Test 2: Nitrogen: 100-140 ppm
Test 3: Phosphorus: 30-40 ppm
Test 4: Potassium: 200-250 ppm
Test 5: Organic Matter: 2-3.5%
Sunflowers:
Part 2: pH and Nutrients
Test 1: Soil pH: 7.0-7.5
Test 2: Nitrogen: 60-100 ppm
Test 3: Phosphorus: 40-50 ppm
Test 4: Potassium: 150-200 ppm
Test 5: Organic Matter: 2-3%
These recommended values for pH, soil nutrients, and organic matter can vary depending on the specific conditions of the farm and the region, so it is recommended for the farmer to conduct soil tests to determine the specific needs of their soil for each crop.

Soybeans: For soybeans, the data revealed that optimal crop yield was achieved in soils with a neutral pH level (around 6.5-7.0) and high nitrogen content, with adequate levels of phosphorus and potassium. Soybeans displayed a strong dependence on nitrogen levels for yield production. The environmental impact also seemed to be influenced by the nutrient content of the soil, suggesting that maintaining proper nutrient levels is crucial for both crop yield and environmental sustainability when growing soybeans.
Sunflowers: In the case of sunflowers, the data showed that sunflowers thrived in well-draining sandy loam soil with a slightly alkaline pH level (around 7.0-7.5) and high levels of phosphorus, along with adequate nitrogen and potassium levels. Sunflowers appeared to be particularly sensitive to phosphorus levels in the soil, showing higher yields when phosphorus content was at optimal levels. The crop impact was closely linked to the soil nutrient levels, indicating the importance of maintaining nutrient balance for sunflower production.
