In agricultural applications, monitoring the quality of the soil is extremely important for the healthy growth of crops. The pH level is an excellent guide as to which plants may thrive in a particular terrain, as well as indicating which conditioners and fertilizers to use. HANNA®' combination test kits allow you to test not only for pH, but for nitrogen, phosphorous and potassium as well, which are all important for the quality of soil.

HI 3896 is very easy to use: A soil sample is diluted in water and combined with one of the chemical reagents supplied with the kit. The result is a colored solution which is compared to the chart provided to determine the concentration of the element being tested. The concentration is given in easily-understood ranges of low, medium and high traces.

The professional HI 3896 kit is supplied with an extraction solution which facilitates the precipitation of suspended solids so that measurements can be taken immediately.

HI 3896 provides for 25 tests and includes a useful guide to measurement.
