For 50 students.
Conduct a thorough evaluation of soil with ordinary soil samples your students can dig up anywhere. We introduce simple, easy-to-follow techniques and staining procedures early on so your students can get the most out of these activities. Soon they're able to identify the type and variety of microorganisms, calculate soil fertility by a cation exchange capacity elimination, test and determine soil pH, and correlate the soil's pH to soil lime requirements.
Kit includes:
12 chem-plates; 12 calibrated tubes; 4 drop-controlled bottles Phenolic Rose Bengal; 3 drop-controlled bottles Barium Chloride solution; 2 drop-controlled bottles of pH Soil Indicator solution; 1 drop-controlled bottle of Potassium Dichromate solution; 50 plastic slides; 50 plastic cups; 50 worksheets and guides; instruction manual with MSDS |
