Soil pH can be determined in the field using inexpensive soil pH testing kits where a small sample of surface soil is mixed with water and reagents which change colour according to the acidity/alkalinity. The soil pH value is determined by comparing the colour and shade to calibrated scales. Soil pH can also be determined using a portable pH meter which involves inserting a rod into a soil-water slurry mixture. Such soil pH tests should be conducted by creating a shallow (5 to 10 centimetre deep) hole in the soil, filling it up with distilled water, stirring to create a slurry mixture, inserting the pH meter rod into the slurry mixture and recording the value displayed on the meter. Alternatively, surface samples can be submitted to a soil testing laboratory accredited by | Soil pH can be determined in the field using inexpensive soil pH testing kits where a small sample of surface soil is mixed with water and reagents which change colour according to the acidity/alkalinity.
