This Hanna Soil test kit is ideal for testing and monitoring the quality of the soil.
Tests include pH level, nitrogen, phosphorous and potassium. Easy to use - a
soil sample is mixed with water and combined with one of the chemical reagents
supplied with the kit. The resulting solution is compared to the colour chart
supplied to determine the concentration of the element being tested, which is
indicated as low, medium or high traces (except pH, which is between pH4 and
pH9, in 1pH increments). The kit comes with all the necessary components for
10 tests of each of the 4 parameters or 25 tests x 4 parameters.
