HI 38080 Calcium and Magnesium Test Kit for Soil SIGNIFICANCE AND USE Calcium and Magnesium are often present in soil as carbonates (e. g. : dolomite), sulfates (in arid regions) and silicates. They are necessary nutrients for plants since they have an important role in plant metabolism and growth. [. . . ] If there is any noticeable damage, notify your Dealer or the nearest Hanna office immediately. Each kit is supplied with: · Buffer Solution pH 10. 2±0. 2, 1 bottle (100 mL); · Calmagite Indicator, 1 bottle with dropper (10 mL); · HI 38080-0 EDTA Solution, 1 bottle (120 mL); · 1 calibrated vessel (50 mL); · 1 plastic pipette (3 mL); · 1 plastic pipette (1 mL); · 1 syringe (1 mL) with tip. Note: Any damaged or defective item must be returned in its original packing materials. · Replace the cap and shake for at least 2 minutes. · Using the syringe, transfer 1 mL of soil extract to the calibrated vessel. Note: to measure exactly 1 mL of sample, take the sy1 mL ringe and push the plunger completely down into the syringe. Insert tip into sample and pull the plunger out until the lower edge of the seal is on the 0 mark of the syringe. Insert the syringe into the vessel and push the sample out until the lower edge of the seal is on the 1. 0 mL mark. · Flip open the top of the Demineralizer Bottle cap. By gently squeezing the bottle, add demineralized water to the plastic vessel up to the 25 mL mark. 25 mL · As the color changes from pink to purple, swirl for 15 seconds after each additional drop, until the solution turns pure blue.
