Surveys on agricultural distribution and agricultural use of fertilizers in Italy
Mario Adua
ISTAT- National Institute of Statistics
Summary
Surveys:
1. Distribution of fertilizers for agricultural use
2. FSS – Survey on structural agricultural holdings
3. Use of plant protection products and fertilizers in major fruit trees cultivation
4. Use of plant protection products in specifics crops
Distribution of fertilizers for agricultural use
General information
Type of source: census statistical surveySurvey unit: fertilizers distributorScope or coverage: distribution of 75 types of fertilizers, crops, volumes in Kg of net nutrients per hectare cultivatedRappresentativity: exhaustive

Variables surveyed
Distributed quantity of 64 types of fertilizersDistributed quantity of 6 types of nutrients (N, K2O, P2O5, mesoelements, microelements, organic substances)Distributed quantity of types of nutrients per cultivated hectare

General information
Type of source: random sampling statistical surveySampling frame: agricultural census databaseSurvey unit: agricultural holding
FSS- structure of agricultural holdings
Scope or coverage: utilized agricultural area, livestock, UDE, use of mineral, organic and organic-mineral fertilizers in agricultural areaRappresentativity: 2,5%Reference period: 2003 - 2005
2 FSS- structure of agricultural holdings
FSS- structure of agricultural holdings
Frequency: on time studyGeographic coverage: NUTS 2Non-response rate:8%Techniques of data collection: face to face interview

Variables surveyedArea of holding treated with chemical fertilizers (ha)Area of holding treated with organic fertilizers (ha)Area of holding treated with organic-mineral fertilizers (ha)Quantity of organic fertilizers distributed by type (manure, sewage, etc)
FSS- structure of agricultural holdings
Use of plant protection products and fertilizers in major fruit trees cultivation3
General information
Type of source: random sampling statistical surveySampling frame: agricultural census databaseSurvey unit: agricultural holdingRappresentativity: 1,25%
Use of plant protection products and fertilizers in major fruit trees cultivation3
Scope or coverage: consumption of 64 types of fertilizers and consumption of 6 types of PPP and 3 toxicology classes by the main fruit trees cultivation Reference period: 2002Frequency of the survey: on the time study
Use of plant protection products and fertilizers in major fruit trees cultivation3
Geographic coverage: NUTS 2Non response rate: 8%Techniques of data collections: face to face interview
Variables surveyed
Quantity of fertilizers utilized per area, per major fruit trees cultivationNumber of holdings treated with fertilizer per major fruit trees cultivation
Use of plant protection products and fertilizers in major fruit trees cultivation
Use of plant protection products in specific crop4
General informationType of source: random sampling statistical surveySampling frame: FSS databaseSurvey unit: agricultural holdingScope or coverage: use of plant protection productsRappresentativity: 0,25%
Use of plant protection products in specific crop4
Reference period: crop yearFrequency of the survey: annualGeographic coverage: NUTS 1Non-response rate: 0% (non responses are replaced)Techniques of data collection: CATI- computer assisted telephone interviewing
Variables surveyedUtilized quantity of PPP, utilized per area and per cropNumber of treatments on PPP per specific cropArea of holding treated with PPPUtilized quantity of types of active substances per hectare
Use of plant protection products in specific crop
Suggestions
We could evaluate the possibility to do a new survey of fertilizers similar to survey
of PPP on specific crop.
Use of plant protection products in specific crop
Conclusion
Distribution of fertilizers for agricultural use
The main source in Italy for each operator connected with fertilizersIt can be considered a good example for other countries
Conclusion
FSS
We can evaluate the possibility to introduce some questions to collect information about fertilizers for each cultivationIt is necessary to estimate costs and benefits
Conclusion
Use of plant protection products and fertilizers in major fruit trees cultivation
It has been a positive experience It is necessary to estimate costs and benefits
Conclusion
Use of plant protection products in specific crop
We can evaluate the possibility to introduce questions about fertilizers to obtain information on specific cropIt is necessary to estimate costs and benefits
Future perspective of ISTAT
It is very important to continue and to develop the surveys on the distribution and use of fertilizersWe are evaluating the opportunity to introduce questions on fertilizers in other surveys (FSS, etc) It very important a financial contribution of UEWe need to evaluate a contemporaneous collection of fertilizers and PPP per crop
Future perspective of ISTAT
It can be useful a task-force in Eurostat
We could evaluate to consider the possibility for a brand new “Regulation on fertilizers statistics”
