Abstract: In view of the executed works, attempt to acquaint the broad audience of researchers with the results of theoretical researches received at the analysis of the results of complex investigations have been carried out. For determining the rational parameters related precision farming requirements to find more suitable parameters and appropriate characteristics. Concerning that our work is based on ecological aspects related to site specific information. The basic sources are influenced of the site specific information by several kind agricultural vehicles, forest harvesters, forwarders and any carrying cross-country vehicles. We have tried to estimate the influence of above mentioned machines and taken into concern their random. Laying down on the obtained basis the respective indices according to the methods worked out (trafficability and soil agrotechnical bearing capability), which is variable for main typical Estonian soils between 170...220 kPa and 50...110 kPa accordingly. Concerning using some cross-country vehicles the variability of soil volume moisture content average 37.2%vol, coefficient of variation 19.1%) and bulk density average 1.21 Mg.m-3, coefficient of variation 31.4%) is quite relatively high. The level of form parameter for that and other characteristics correspondingly is equal to 27 (k = 27) and 10 (k = 10) which were shown that the cross-country vehicles increase the changeable of soil physical properties at landscape and is back-proportional to suitable level of coefficient of variation.

Key words: precision farming, soil compaction, soil bulk density, trafficability

Streszczenie: Aspekty ekologiczne ugniatania gleby podczas przejazdów maszyny. Na podstawie wyników badań podjęto próbę określenia parametrów gleby zgodnych z wymaganiami rolnictwa precyzyjnego. Stwierdzono, że zwięzłość gleb estońskich mieściła się w przedziałach 170-220 kPa i 50-100 kPa, w zależności od liczby przejazdów kołami ciągników i maszyn rolniczych oraz rodzaju gleby. Czynniki te wpływają również na znaczną zmienność objętościowej zawartości wody w glebie (19,1%), przy średniej wartości 37,2%, oraz na gęstość objętościową gleby (31,4%), przy średniej wartości 1,21 Mg.m-3.
