What should I ask a soil laboratory?

Ask about soil texture and compatible field-capacity and wilting-point measurements for your effective root zone.

A little more detail

Contact the laboratory before collecting samples. Ask how and where to sample, which methods they use, what units the report contains and whether the two water measurements form a compatible pair. Keep the report date and laboratory identity with the values.

Scientific and source detail
