Discussion 

The importance of this research project is to help the Erie Street Community Garden by determining which soil properties are helpful and which are harmful to plant growth. Our lab group wanted to determine if the soil properties in apple tree soil and peach tree soil were significantly different. We did research to determine if the soil properties in both conditions were optimal for the growth of both apple and peach trees to better help the Erie Street Community Garden and the people of Lafayette, IN.

Conclusion

Through our research, our group was able to determine that, for both apple and peach trees, the biggest growth inhibiting factors were that the soil pH being slightly too high or basic and  insufficient moisture content for fruit trees. According to Utah State University's Intermountain Tree Fruit Production Guide, at about 50% readily usable moisture content, fruit trees begin to experience drought stress, causing inadequate crop production. Since around 30% moisture content would be optimal condition, it would be beneficial for GrowLocal to prioritize their irrigation management for their Erie St. Garden location.
