What is ISO 11276 - Soil quality about?
ISO 11276 specifies methods for the determination of pore water pressure in both unsaturated and saturated soil using tensiometers.
The methods described in ISO 11276 are applicable for in situ pore water pressure measurements in the field, as well as for monitoring pore water pressure in, for example, plant containers or soil cores used in experimental Procedures. At normal atmospheric pressures, i.e. about 100 kPa, the application of these methods is limited to a range of pressures down to about – 85 kPa. The range is reduced at lower atmospheric pressures.
Who is ISO 11276 - Soil quality for?
ISO 11276 on Soil quality is useful for:
- Ecologists and conservationists
- Soil testing laboratories
- Landowners
- Researchers involved in soil sciences / agricultural researchers
Why should you use ISO 11276- Soil quality?
A tensiometer provides point measurements of pore water pressure. To measure pore water pressure at different depths, several tensiometers will be necessary. In the field, replicate sets of instruments will be required if the spatial variability of the soil is to be allowed for.
ISO 11276 provides methods and procedures for determining the pore water pressure using the tensiometer method.
ISO 11276 specifies methods for measuring pore water pressure, sampling, and monitoring, and preparing samples for the testing methods.
As a result of the ISO 11276, you can determine the pore water pressure from the soil, improving the fertility of the soil, making it more nourishing and promoting the growth of crops, and will be widely accepted by farmers worldwide.
