“…Though not the subject of presented paper, Ca and Mg losses by water erosion are usually high (e.g. Fullen et al 1997;Bertol et al 2003;Zhang et al 2004b) and their removal can affect soil pH. Treatment erosion rates were variable and base cation loss could have an influence on differences in original soil pH between treatments.…”

“…However, although direct experimental evidence of the "infiltration trade-off hypothesis" (Bruijnzeel, 1989;Bonell et al, 2010) is missing due to a lack of comprehensive studies, demonstrated reductions in amounts of headwater-or hillslope stormflow production after reforesting severely degraded land in various parts of the tropics (e.g. Chandler and Walter, 1998;Zhou et al, 2002;Zhang et al, 2004) should be large enough to overcome the associated increases in forest water use (Chandler, 2006;cf. Bruijnzeel, 2004;Scott et al, 2005;Zhou et al, 2010).…”

“…Unfortunately, to date, no unequivocal case of a positive relationship between changes in Q and reforested degraded area has been reported in the tropics (cf . Table 6), although demonstrated decreases in the amounts of headwater-or hillslope stormflow generation after reforesting severely degraded land (Chandler and 1998; Zhou et al, 2002;Zhang et al, 2004;Sun et al, 2006) must be considered large enough to overcome the associated increases in forest water use (Chandler, 2006;cf.

Abstract. Although regenerating forests make up an increasingly large portion of humid tropical landscapes, little is known of their water use and effects on streamflow (Q). Since the 1950s the island of Puerto Rico has experienced widespread abandonment of pastures and agricultural lands, followed by forest regeneration. This paper examines the possible impacts of these secondary forests on several Q characteristics for 12 mesoscale catchments (23-346 km 2 ; mean precipitation 1720-3422 mm yr −1 ) with long (33-51 yr) and simultaneous records for Q, precipitation (P ), potential evaporation (PET), and land cover. A simple spatially-lumped, conceptual rainfall-runoff model that uses daily P and PET time series as inputs (HBV-light) was used to simulate Q for each catchment. Annual time series of observed and simulated values of four Q characteristics were calculated. A least-squares trend was fitted through annual time series of the residual difference between observed and simulated time series of each Q characteristic. From this the total cumulative change (Â) was calculated, representing the change in each Q characteristic after controlling for climate variability and water storage carry-over effects between years. Negative values ofÂ were found for most catchments and Q characteristics, suggesting enhanced actual evaporation overall following forest regeneration. However, correlations between changes in urban or forest area and values ofÂ were insignificant (p ≥ 0.389) for all Q characteristics. This suggests there is no convincing evidence that changes in the chosen Q characteristics in these Puerto Rican catchments can be ascribed to changes in urban or forest area. The present results are in line with previous studies of mesoand macro-scale (sub-)tropical catchments, which generally found no significant change in Q that can be attributed to changes in forest cover. Possible explanations for the lack of a clear signal may include errors in the land cover, climate, Q, and/or catchment boundary data; changes in forest area occurring mainly in the less rainy lowlands; and heterogeneity in catchment response. Different results were obtained for different catchments, and using a smaller subset of catchments could have led to very different conclusions. This highlights the importance of including multiple catchments in land-cover impact analysis at the mesoscale.

“…According to these authors, the upper slope of a gravelly Alf isol in southwestern Nigeria was more resistant to soil degradation as 16-67% loss in maize yield was observed compared to 65-75% loss in yield at the lower slope. Efforts have been geared toward rehabilitating such marginal lands or sustaining their productivity with low-input technologies suitable for adoption by the resource-poor farmers of these nations (Kang et al, 1997;Kirchhof and Salako, 2000;Zhang et al, 2004;Salako et al, 2007).…”

“…takes several weeks of the early growth stages to provide reasonable ground coverage (Onwueme, 1978). 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...
