Financial burden to farmers

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

To determine the total burden that the 2017 outdoor vegetable crop survey placed on those providing the information, the surveyors recorded the time that 39 respondents spent providing the data during the surveys. This sample represents 46 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” hourly pay for Scotland of £13.98) ^{( 10)}

The total financial burden to all growers resulting from participation in the 2017 outdoor vegetable crop survey was calculated to be £196.
