When creating the list, the selected products should represent the fluctuations of prices also for the products not included in the list.

Part of the data is collected by sample survey (coverage of about 70%) through forms, from companies and other organizations engaged in the sale of animal feed, mineral fertilizers and plant protection products in the field of agriculture. In addition, data on other product groups, such as seeds, machinery and energy products in agriculture, are taken from other surveys within price statistics

Quarterly

The survey uses the reporting method of data collection. There are four C-52 forms for: nutrients, mixtures, mineral fertilizers and plant protection products. The reporting unit fills the questionnaire on the basis of the documentation and records at its disposal.

The staff of the Price Statistics Division performs checking of prices on questionnaires and control of data entry by comparing calculated monthly indices between the current and the previous month and clarifies all significant changes with reporting units via the telephone and e-mail.

Weights represent the participation of individual products and groups of products in the total value of sales (product weightings and product groups), as well as the participation of reporting units in the total sold quantities of products (weights of reporting units). Product weights are used to calculate the price index of product groups, while using the weight of product groups calculates the total price index of reproduction material, labor and services in agriculture. Reporting unit weights are used to calculate the product price index, as well as average monthly prices.

Price indices are the relative numbers that show price changes in one period relative to the other for a given territory.

Price indices are calculated for individual products (individual indices), for groups (group indices) and for all products entering the index list (total index). Indices (individual, group and total) can be base (with fixed base) or chain (with variable
