Soil acidity and alkalinity are common fertility problems that can cause stunted growth and abnormally coloured leaves. If you are having trouble determining the reasons for poor growth or plant health, testing the pH of the soil/media is a great place to start.
Low soil pH causes aluminium ands manganese toxicity in plants and reduces the availability of soil phosphorus. High soil pH also reduces soil phosphorus availability and reduces micronutrients such as zinc and boron to plants.
This high quality pH probe is designed specifically for measuring the pH of soils.
It can easily be fitted to the Bluelab pH Meter or Bluelab Combo Meter.
