The paper presents an assessment of the influence of biological conditions for farming in selected agricultural districts on the quantity of basic and specialist means of production on farms described by many authors as agricultural infrastructure of these farms. The conditions of crucial importance for the method and results of farming are the indices of soil agronomic usability, size and agrarian structure and other natural conditions, e.g. agroclimate, area relief and aspect, water conditions, etc. Spatial analysis comprises spatial distribution of agricultural infrastructure potential as a synthetic index of development and subsequently, considering this index as a measure of development, determining a portion of groups similar considering soil quality and other biological conditions of agricultural management (spatial evaluation index). For comparison, technical infrastructure of agricultural holdings was characterized using aggregated synthetic index of many diagnostic features, whose construction bases on Hellwig development measure. Data for the analysis were taken from the results of Agricultural Census 2002 and data on agronomic usability of soils and biological framing conditions supplied by IUNG at Puławy. Proper technical infrastructure of agricultural holdings is one of more important factors affecting the character of agriculture. In many cases the infrastructure on farms of Polish villages is ...
