SAMPLING IN AGRICULTURE SLOVENIA Stratification is based on the data on production due to mixed type of agricultural production in Slovenia At least 1 species of animals is bred at 87% of ag.h. Arable land is cultivated by 93% of ag.h. Type of farming calculated in FSS 49 % of farms have mixed type of farming 35 % of farms are specialized in livestock rearing and milk production 16 % of farms are spcialized in arable and permanent crop production

SAMPLE FRAME and SIZE for the PESTICIDE INDICATORS SURVEY In the FSS sample we have around 5000 farms cultivating wheat From that frame we will select a stratified sample of 2900 farms cultivating wheat All enterprises cultivating wheat will be included (around 100)

DATA COLLECTION METHODS for the PESTICIDE INDICATORS SURVEY One of the aims of the Pesticide indicators survey is to test appropriatenes of different modes of data collection for the survey about pesticide use On the basis of available resources we will devide the sample of 2900 farms in: Paper assisted personal interviewing (PAPI) ~ stratified sample of around 200 farms Postal surveys (POST) ~ stratified sample of around 1350 farms Computer assisted telefon interviewing (CATI) ~ stratified sample of around1350 farms
