Title : Wear degree and structure for technical fixed assets in different types of farms
Key words : technical means of production, building structures, mechanical facilities, physical wear, functional wear, replacement value
Summary :

The purpose of this work was to analyse the degree of wear (technical, functional and environmental) and the value of technical means of production in selected fruit-growing farms, compared to farms involved in typically agricultural production.

Field research completed for 180 farms (vegetable-growing, fruit-growing and diversified) allowed to acquire detailed information concerning their possession of both technical equipment and building structures serving production purposes. The scope of the research covered more than 5000 mechanical facilities and almost 900 building structures.

The subject of the work included:

a) mechanical facilities (mechanical tractive force, tools, machines, means of transport, etc.);

b) building structures (livestock and storage buildings, garages, etc.).

In case of the first group, the researchers determined the impact on wear degree of the following parameters: age of the means, scale (arable land area), commodity character of production (vegetable / fruit), storage methods, service quality (independent or provided at specialist plants, carrying out recommended technical surveys).

In case of building structures, the researchers determined the impact on wear of such factors as: age of structures, scale (arable land area), commodity character of production (vegetable / fruit), carried out overhauls / repairs, condition of a structure service environment.

Obtained results were analysed within farm groups divided according to two criteria, that is: arable land area and commodity production volume. Detailed analysis was carried out also for the groups of individual mechanical facilities and building structures. Acquired research material allowed to deter-mine factors deciding about wear degree, structure and rate for technical fixed assets in form of mechanical facilities and building structures in vegetable-growing, fruit-growing and diversified farms. A mathematical model representing physical wear process was developed for selected mechanical facilities.
