Monitoring the quality of the soil is extremely important for healthy crops. The pH level is an excellent guide as to which plants may thrive in a particular terrain, as well as indicating which fertilizers to use.
These test kits allow you to test not only for pH, but also for nitrogen, phosphorous and potassium.
The HI3895 and HI3896 are very easy to use: A soil sample is diluted in water and combined with one of the chemical reagents supplied in the kit. The result is a colored solution which is compared to the chart provided to determine the concentration of the element tested. The concentration is given in easily understood ranges of low, medium and high traces.
