In horticulture, monitoring the quality of the soil is extremely important
for the healthy growth of plants. The pH level is an excellent guide
as to which plants may thrive in a particular growth media, as well
as indicating which fertilizers to use. HANNA’s combination test kits
allow testing on not only for pH, but for nitrogen, phosphorous and
potassium, which are equally important for the quality of the soil.
HI 3896 provides for 25 tests and a useful guide to measurement.
