Financial burden to growers

In order to minimise the burden on farmers the survey uses non-visit methods of collection, such as email, post or telephone call, where possible.

To determine the total burden the 2015 Protected Edible Crop survey placed on those providing the information, the surveyors recorded the time that 15 respondents spent providing the data during the survey. This sample represents 94 per cent of growers surveyed. The median time taken to provide the information was 10 minutes.

The following formula was used to estimate the total cost of participating:

Burden (£) = No. surveyed x median time taken (hours) x typical hourly rate*

(* using median "Full Time Gross" pay for Scotland of £13.45) 3

The total financial burden to all growers resulting from participation in the 2015 Scottish Protected Edible Survey was calculated to be £34.
