Uses 21st century universally recognised & preferred laboratory method
(Chemist)
Serious gardeners want a soil (and water) pH test kit. They also want it to be accurate and reliable!
Since soil pH controls the availability of nutrients to plants, gardeners need accurate information on the pH of their soil and water to ensure it is optimum for the type of plants they grow. Flairform's Soil & Water pH Test Kit is unique:
CHECK THESE FEATURES
*This kit solves the problem caused by fact that reported soil pH values are significantly method dependent – i.e. different methods give results which vary by 0.5 – 2 pH units from each other. Thus soil pH values obtained from different sources are usually not comparable. Consequently, tables of recommended soil pH values for particular plant species must be interpreted with caution. Therefore, it is important that industry makes an attempt to standardise on a particular method - ideally the current preferred lab method – on which this kit is designed.
