Soil Quality
O ur project was to figure out how much acid, phosphate, and organic matter there is in soil from three different farming areas near our town. We hoped to find what kind of farming is best for soil quality.
Research Question: The goal of our project was to determine what quality the soil was in three areas: CRP (Conservation Reserve Program, the land is pulled out of production), No Farming and Rotated (the type of crops planted are rotated on an annual or biannual plan). In November, we collected three samples per area using shovels and gallon jugs. We also conducted five tests on the soil to determine soil quality: pH, Soil Texture, Humus, Phosporous (P), and Nitrogen (N) levels.
Results:

pH: Measures the level of acidity in the soil. Soil Texture: Indicates the percent of sand, silt, and clay in the soil. Humus:Indicates the amount of organic matter in soil Phosphorus: Stimulates the formation of healthy seed. By stimulating rapid cell development in the plant, phosphorus naturally increases the resistance to disease. Nitrogen Levels: Nitrogen is the most prevalent nutrient element in the makeup of plants.
