“…We observed no increase in soil compaction in rehabilitated plots as measured by bulk density and resistance to penetration ( Table 1). The net effect of soil movement was that soil properties were shifted vertically upward by 15-20 cm in areas of soil removal (footslope and toeslope) and shifted downward by 15-20 cm in areas of soil addition (summit, shoulder, and upper backslope), with a large increase in surface soil OC and nutrients from the addition of 15-20 cm of high-organic-matter material to rehabilitated plots ( Table 1) (2).…”

Information regarding solute and water transport as affected by soil properties, topography, and climatic conditions is required to improve and validate transport models. This study evaluated the dissipation of bromide applied to the soil surface in the fall and spring to undisturbed (eroded) and rehabilitated landforms, in which topsoil was moved from depositional areas to the eroded upper slope. Despite large changes in soil properties, the amount and center of mass of bromide remaining in the top 1 m of soil was the same in undisturbed and rehabilitated plots. Approximately 60% of the fall-applied bromide was lost during the winter and early spring, presumably due to leaching and runoff. The center of mass of spring-applied bromide remained at depths of <30 cm. At the end of the experiment, 33% of the spring-applied bromide was detected in soil and 56% in corn plants. These results suggest that little bromide was leached out of the root zone in the spring and that plant uptake was a major route of bromide dissipation during the growing season.

“…The price of 100 kg of DAP was 360 Ethiopian Birr currency (ETB) (C21. 18), and that of 100 kg urea was 320 ETB (C18.82). The replacement cost in the catchment was projected to the scale of the Tigray region and Ethiopian highlands.…”

“…Studies of erosion-induced changes in soil properties at the field scale have constantly shown that soil texture, surface soil organic carbon, nitrogen, and phosphorus concentrations are higher in areas of soil deposition compared to areas of soil removal by erosion [18]. Assessing the effect of erosion on soil properties variability as a result of nutrient export from catchment landforms can provide more meaningful results.…”

Even though soil degradation challenges sustainable development, the use of degradation indicators such as nutrient export (NE) and nutrient replacement cost is not well documented at landform level. This study is aimed to investigate the extent of soil degradation, NE rates, and their replacement cost across landforms in the Mai-Negus catchment, northern Ethiopia. Different erosion-status sites (aggrading, stable, and eroded) in the landforms were identified, and soil samples were randomly collected and analysed. Nutrient export, replacement cost, and soil degradation were calculated following standard procedures. This study showed that soil degradation in the eroded sites ranged from 30 to 80% compared to the corresponding stable site soils, but the highest was recorded in the mountainous and central ridge landforms. Average NE of 95, 68, 9.1, 3.2, 2.5, and 0.07 kg ha −1 y −1 for soil calcium, carbon, nitrogen, potassium, magnesium, and phosphorus, respectively, was found from the landforms. Significantly strong relationships between NE and sediment yield in the landforms were observed. Annual nutrient replacement costs varied among the landforms though the highest was in the reservoir (C9204 in May 2010). This study thus suggests that while introducing antierosion measures, priority should be given to erosion sources to the reservoir such as mountainous and central ridge landforms.

“…Furthermore, the landform elements also provide practical units for management (Pennock 2005, Li et al, 2008. With the knowledge of the soil erosion pattern across different landform elements, it is possible to develop Best Management Practices (BMP) that target on specific landform elements (e.g., Goddard, 2005;Pennock, 2005;Li et al, 2008;Papiernik et al, 2009).…”
