|Summary:||Interconnected , this described the nutrient cycles; the conversions, transformations, and movement of nutrients through the soil, abiotic and biotic components of the environment. This activity uses a qualitative nitrate to observe results of some conversions and transformations in the nitrogen cycle. Qualitative nitrate test strips change color when exposed to nitrate; the color deepens as nitrate concentration increases. Ammonium and nitrate sources, water and sugar will be added to soil in various combinations. After incubation, nitrate will be measured with the strips.|
