Discover how productive soil samples might be for farming purposes. Conduct hands-on experiments to test different soil samples for water-holding capacity, pH, and levels of plant macronutrients (nitrogen, phosphorus, sulfur, magnesium, and calcium). Designed for 12 groups of 2 to 3 students.
Students explore the chemical characteristics of soil samples to discover how productive the samples might be for farming purposes. Using multiple testing methods, students conduct hands-on experiments to compare several sites and soils of various compositions. The kit is designed for 12 groups of 2 to 3 students. Each group tests a different soil sample for water-holding capacity, pH, and levels of plant macronutrients (nitrogen, phosphorus, sulfur, magnesium, and calcium).
