The paper presents analises of map which used to real property valuation. Particularly there are exactly considered soil - agriculture maps. Analysed soil erosion is very useful for interpretation of terrain physiology and in conseguence to estimation of properties.

In years 2007-2009 soil erosion measurements were conducted on plots and hillslopes with not separated area. The separated plots were closed by the Gerlach troughs with collectors. Measurements with not separated area were carried with the modified collectors of Słupik (entrance width 0,5 m). The aim of the paper is to compare the results and to evaluate the usefulness of the small collectors. Annual amounts of eroded soil occurred to be 12% smaller for cereals and 26% smaller for potatoes in comparison with erosion recorded in the separated plot. On a convex slope amounts of eroded material were higher (20% on average). On the other hand, the erosion on a concave slope was less effective (c. 35%) during any rainfall conditions. Mass of soil material collected in 10 collectors situated near each other was compared. It is calculated that measurement error due to the collector effectiveness and local differentiation of the geomorphic processes is ±6% if only two neighbouring collectors are considered and up to ±4% if tree catchers are taken into consideration. This error increase up to ±30% during small erosivity rainfalls (El₃₀< 20 MJ mm ha⁻¹h⁻¹).

Long distance slope transport has been relatively rarely observed in the Polish lowlands. This study concerns the observation of this process which occurred in: • the large denudational valley at Bartochów which cuts the consistent complex of morainic hillocks named the Warta Hillocks, • the large gully at Jasień locality which cuts the right side of the Mroga river valley in the area of the Łódź Heights, • the denudational valley and the long road holweg which cut the high terrace of the Mroga river at the Rogów site. The long transport at Bartochów at the distance of nearly 2000 m followed the short thought heavy downpour in May 2004. On the slopes of the denudational valley numerous erosional furrows developed while its bottom became coated with slope covers. At the end of this rainfall, the covers became cut by episodic erosional channels while at the valley outlet the extensive accumulation fan was formed. The traces of slope processes forming the gully at Jasień have been detected from air photos from 1958. In the spring 2004, after the abundant melt, the soil erosion and the long distance slope transport of about 500 m occurred in this gully. The floor of the lower section of the gully was covered by slope deposits and transformed by erosional holes and channels. The aerial photos took in 1957 show that both the denudational valley and the road holweg at Rogów were modelled by episodic erosional channels at the distance of about 400 m. The total length of these channels was 600 m. The processes of soil erosion and long distance slope transport occur there every year and continue up to now. The long distance slope transport is entirely connected with concave landforms (e.g. denudational valleys, gullies, road holwegs) and areas built of deposits susceptible to erosion (e.g. sandy alluvia, slope silts and sands, occasionally fluvioglacial sediments). It is generated by heavy downpours when crops are poorly developed and also by rapid melt over frozen ground. Long distance slope transport is entirely present in agricultural areas and its occurrence is facilitated by errors in agricultural management.
