Soil Properties Testing Kit

This kit provides materials for 8 groups to test local soil samples for pH, nitrogen, phosphorus, potassium, and physical properties within a single coordinated kit. Students use sand, clay, and local samples to examine how different soil compositions relate to measurable chemical and physical characteristics. The kit includes soil pH indicator solution, soil nutrient extracting solution, phosphorus and nitrate reagents and indicator powders, potassium reagent and indicator powder, sand, clay powder, detergent powder, extraction bottles, jars, pipettes, soil scoops, coffee filters, cups, and pH/N/P/K color charts.
