“…The highest percentage SOM was on less eroded 2-5°slopes and the least on 10-14°slopes. For historical reasons, soil analytical techniques were mainly Russian procedures (Jankauskas and Fullen 2002). Therefore, analytical results differ from those generated by current internationally accepted protocols (e.g., USDA), but are consistent with former Soviet protocols (Jankauskas and Jankauskiene 2003).…”

“…Conditions for water erosion in Lithuania were characterized by Jankauskas and Fullen (2002). Data were obtained during 1983-2000 from the Kaltinenai Research Station of the Lithuanian Institute of Agriculture (KRS of LIA), which is located on the southern-central Zemaiciai Uplands (55°34′N, 22°29′E) (Fig.…”

“…Soil erosion rates increased with slope steepness and changed soil physico-chemical properties. Therefore, natural soil fertility decreased 22, 40 and 62% on slopes of 2-5°( 3.5-8.3%), 5-10°(8.3-17.7%) and 10-14°(17.7-26.3%), respectively (Jankauskas and Fullen 2002). …”

Jankauskas, B., Jankauskiene, G. and Fullen, M. A. 2004. Erosion-preventive crop rotations and water erosion rates on undulating slopes in Lithuania. Can. J. Soil Sci. 84: 177-186. A combination of perennial grass species and selected crop rotations can help prevent soil erosion in upland regions and minimize the risk of soil erosion and associated water pollution (to both terrestrial and aquatic ecosystems). Research data were obtained on sandy loam Eutric Albeluvisols at the Kaltinenai Research Station of the Lithuanian Institute of Agriculture on the undulating hilly topography of the Zemaiciai Uplands of Western Lithuania. The aim was to identify crops and crop rotations that would minimize soil erosion. Measured water erosion rates over 18 yr of field experiments were: 3.2-8.6 m 3 ha -1 yr -1 under winter rye, 9.0-27.1 m 3 ha -1 yr -1 under spring barley and 24.2-87.1 m 3 ha -1 yr -1 under potatoes. Perennial grasses completely prevented water erosion, while the erosion-preventive grass-grain crop rotations (>50% grass) decreased soil losses on arable slopes of 2-5°, 5-10°and 10-14°by 75-80%. The grain-grass crop rotation (<50% grass) decreased rates by 23-24% compared to the field crop rotation. The main attributes of the proposed soil conservation systems were the careful selection of optimum erosion-preventive ecosystems (sod-forming perennial grasses or erosion-preventive crop rotations) with high erosion-resisting capabilities. These selected systems varied in response to slope gradient and thus assist erosion control and ecological stability of the undulating topography of Lithuania. These results may have wider applicability on the undulating landscapes of the temperate agricultural zone.

“…About 17% of Lithuania's agricultural land is eroded, increasing to 43-58% in hilly regions (Jankauskas, 1996;Jankauskas, Fullen, 2002). Erosion processes affect the majority of the overall rolling terrain of Lithuania by over 20-30% and by more than 30%.…”

Agricultural experts' perception and knowledge towards farming conditions and natural agro-environmental problems are important to develop a sustainable rural strategy and may serve when planning land use in sloping agricultural areas to avoid land abandonment. The objective of investigations was to analyze the attitudes of agricultural experts in the Eastern Lithuania region towards the state of the generic agrarian sector, soil erosion processes and natural handicaps. Replies of respondents indicated that the means (the Likert Scale) of the evaluation towards the items "Soil quality", "Agricultural sector development" and "Land suitability for generic agricultural activity" were 2.68, 3.11 and 2.73, respectively. The evaluations indicating that the mean score perceived by respondents towards impact of soil erosion on common farming activity in the region was 2.63. A questionnaire study showed that respondents recognized that the impact of terrain and soil texture factors on the potential of soil erosion processes is the highest in the region, thus the factor of soil type has been evaluated as the least important. The most frequently noticed topographical parameter of the terrain influencing the intensity of soil erosion was slope steepness (63.1% of respondents), followed by slope aspect (21.1%) and length (15.8%). Hilly terrain and soil acidity constraints by frequency 24.5 and 18.9%, respectively, have showed the most important attitude of respondents, in the content of the natural handicaps limiting successful farming activity in the region. However, the study disclosed that unfavourable climate conditions and soil cover diversity were the two least crucial natural constraints for farming. These empirical findings intended to bring benefits and can help in decision-making framework in order to decide the best soil conservation measures and improving farming conditions in agricultural areas under natural handicaps.

“…About 52% of Lithuania's relief is undulating hills, where the soil is erodible (Kudaba, 1983) and $17% of Lithuania's agricultural land is eroded, increasing to 43-58% in the hilly regions (Jankauskas, 1996;Jankauskas and Fullen, 2002). The hilly rolling relief of Lithuania, dissected by gullies and river valleys, was formed in the early Holocene, after glacial melting $12 000 years BP (Baltrunas and Pukelyte, 1998).…”
