Plant Nutrient Analysis Kit

This kit provides materials for 10 groups to extract plant nutrients into solution and evaluate nitrogen, phosphorus, and potassium levels using colorimetric testing. Students compare test results against included color charts to identify nutrient restrictions and assess crop nutrient status. Included materials cover the full extraction and testing sequence, with plant nutrient extractor solution, nitrate and phosphorus reagents and indicator powders, potassium reagent and indicator powder, extraction bottles with caps, filter paper, scoops, pipettes, and NPK color charts. A Teacher's Manual and Study Guide copymaster support data collection, analysis, and discussion.
