Purpose of the pH-meter
To make the soil suitable for the absorption of fertiliser, acidic soil must be neutralised with lime or a lime-based fertiliser. However, if too much lime or lime fertiliser is used, the result will be a manganese deficiency causing complete infertility of the soil. Therefore, if a lime treatment of the soil is required, it is recommended first to determine the degree of acidity, i.e. the pH of the soil to have a basis on which to decide how much lime must be added. This can be simply done with the pH-meter which has already been successfully used by many market gardened. A perfectly neutral soil has a pH = 7; the instrument should always indicate this value before taking any readings.
- Scale : pH 3½ – 8/moisture 0-100% (no battery neccessary)
- Accuracy : 10%
- Size/weight : 160 x 50 mm/210 grams
