“…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). Currently, efforts are underway to develop transfer functions between Soviet and international systems and this will be the subject of separate communications.…”

“…Soil erosion was mainly caused by tillage and water erosion under continuous intensive cropping. The typical cropping mix was grain crops (~50%), tillage crops, such as potatoes and beets (~17%) and perennial grasses (~33%) (Jankauskas and Jankauskiene 2003). The agro-chemical properties of Ap horizons (0-20 cm) before field experiments shows topsoils were slightly acid, P-deficient, medium rich in K and contained varying soil organic matter (SOM) contents (Table 1).…”

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.

“…Runoff and soil erosion are strongly and positively or negatively correlated with ground cover (El-Swaify et al, 1988;Renard et al, 1997;Frasier and Hart, 2003;Gabriels et al, 2003;Zhang et al, 2004). Therefore, the conservation effectiveness of any crop rotation systems depends on ground coverage effectiveness of the individual crops in the system (Gabriels et al, 2003;Jankauskas and Jankauskiene, 2003) and residue management (Fischer et al, 2002).…”

Resource-poor farmers in developing nations cultivate marginal lands, thereby exacerbating the problem of soil degradation through poor plant growth and ground coverage. An assessment of ground cover under such a practice will provide a guideline for soil conservation. Ground cover by leguminous cover crops (e.g., Mucuna pruriens, Pueraria phaseoloides and Vigna unguiculata), associated with yam, maize and rice was measured in three different experiments in southwestern Nigeria using beaded-string method while leaf area was measured using a flat-bed scanner. The leaf area was used in obtaining equivalent of ground cover fraction from the leaf area index. Ground cover by yam was < 15% at 10 wap (weeks after planting) in the second year of cropping and was < 25% at 25 wap in the fourth year of cropping. Maize+legume ground cover was < 40% at harvest (14 wap) in the third year of cropping. At 10 wap, rice 'WAB 189' had significantly higher ground coverage (43.8%) than 'ITA 321' (32.5%) and 'WAB 450' (33.2%). Both the beadedstring and scanning methods were close in the values of ground cover fractions for upland rice, but not for maize, indicating that prediction equation cannot be generalized for crops with different morphology. Cover cropping and residue mulching are good practices for low-intensity cultivation of marginal lands to achieve soil conservation effectiveness.Additional key words: cover cropping, crop rotation, Dioscorea spp, Oryza sativa, residue management, soil conservation, Zea mays. ResumenRecubrimiento del suelo con tres cultivos en tierras marginales del sudoeste de Nigeria e implicaciones en la erosión Los agricultores con pobres recursos de las naciones en vías de desarrollo cultivan tierras marginales, aumentando el problema de la degradación del suelo debido a un escaso crecimiento de las plantas y pobre cobertura del suelo. Evaluar la cobertura del suelo bajo estas prácticas aportará información para la conservación del suelo. En tres experimentos diferentes en el sudoeste de Nigeria se ha medido la cobertura del suelo en cultivos asociados de leguminosas (Mucuna pruriens, Pueraria phaseoloides y Vigna unguiculata) con maíz, ñame, y arroz, usando el método de la cuerda marcada y un medidor de área foliar. Se obtuvo la fracción de cubierta del suelo a partir del índice de área foliar. La cobertura del suelo por el ñame fue < 15% 10 sdp (semanas después de la plantación) en el 2º año de cultivo, y < 25% a las 25 sdp en el 4º año del cultivo. La cobertura del suelo con la asociación de maíz y leguminosas fue < 40% en el momento de la cosecha (14 sdp) en el 3 er año del cultivo. El arroz 'WAB 189' cubrió el 43,8% a los 10 sdp, considerablemente más que 'ITA 321' (32,5%) y 'WAB 450' (33,2%). La cuerda marcada dio valores de la cubierta del suelo pró-ximos a los del medidor de área foliar en el caso del arroz de las tierras altas, pero no en el maíz, indicando que la ecuación de predicción no puede generalizarse para diferentes cultivos. La cobertura de cultivos y el acolchado con residuo...

Lithuania has a temperate climate, transitional between maritime and continental. Weather conditions are variable, with frequent winter frosts and cool, humid summers. The mean annual temperature is 6 C; the January mean is À4.8 C and July 17.2 C. The climate is humid, with a mean annual precipitation of 675 mm. However, this is spatially variable, being highest (920 mm) in the south-west Zemaiciai Uplands and lowest (520 mm) in the northern Central Lithuanian Lowland. The Lithuanian climate is conducive to water erosion and heavy showers are particularly erosive. Heavy showers with >30 mm of rain occur in the Central Lithuanian Lowland about once every 2 years, in the south-west Zemaiciai Uplands about three times every 2 years and elsewhere about once per year. The mean wind velocity on the Baltic coast is 5.5-6.0 m s À1 and decreases to 2.9-3.5 m s À1 inland. In winter, owing to active cyclonic activity, wind velocities are 1-2 m s À1 greater than in summer (Arlauskiene et al., 2001).Lithuania occupies the western fringe of the East European Plain and is predominantly a lowland country. These lowlands are separated by hilly uplands, forming two meridian-oriented stretches. The western edge of the Baltic Uplands is in the east and south of the Republic, where erosion processes affect large areas. The 'island-like' Zemaiciai Upland is in the west, where erosion processes affect 5.1-20 and 20-30% of the undulating terrain (Figure 1.6.1).Moraines are the prevalent soil parent material, deposited in glacial margin and basal conditions. Ground moraine covers 30% of the national territory and glacial margin formations 27%. Glacio-lacustrine formations cover 23% and fluvioglacial formations 7%. Peaty, marine (littoral), aeolian and karst formations occupy only 0.2-1% (Arlauskiene et al., 2001).
