“…These soils are characterized by poorer soil fertility due to nutrient depletion leading to increased soil acidity which, in turn, declines yields unless fertilizer is applied (Hartemink and Van Kekem, 1994). Despite technical considerations during terrace construction, bench terracing has been claimed to be efficient in conserving soil moisture as result of the levelling of the slope followed by reduced soil run‐off (Kannan et al ., 2010). Thanks to a relatively good drainage on Mugugu soils, crop performance on terraces can therefore be explained by other factors, including subsequent use of fertilizers, farm management and particularly inherent variation of physical and chemical soil properties (Siriri et al ., 2005; Kannan et al ., 2010).…”

Bench terracing has received considerable attention from soil and water conservation (SWC) programmes involved in soil erosion control in Rwanda. It is questioned, however, whether enough attention is paid to the suitability of the soils and to the eventual financial profitability. Terraces may reduce soil erosion and increase production but they should also provide sufficient financial gains at farm level. A plot level financial cost–benefit analysis was undertaken to examine under which social and economic conditions bench terraces are financially viable in Northern and Southern Rwanda. Farmers' estimates of respective costs and potato yields from plots with subsidized and un‐subsidized bench terraces, progressive terraces and plots with no terraces at all were obtained for the analysis. Costs of labour and manure were found to be the most influential for the profitability of bench and progressive terraces. While the cost–benefit analysis, using market prices, showed that bench terraces would be hardly profitable, an analysis with opportunity costs for labour and manure indicated that bench terraces and even more progressive terraces can be financially profitable. Extra measures and incentives may be required to facilitate use of labour and access to manure, as now achieved with the one cow per family policy. This paper suggests that further studies should be undertaken to determine costs and benefits of bench terraces beyond private perspective in Rwanda. Copyright © 2010 John Wiley & Sons, Ltd.

“…Accurately quantifying soil moisture and electrical conductivity (i.e., salinity) is critical for numerous agricultural (e.g., Kannan et al, 2010;Suweis et al, 2010), engineering (e.g., Fang-zhi and Xiao-ping, 2010), and environmental (e.g., Rodriguez-Iturbe et al, 2007;Suweis et al, 2010) applications. Multiple methods for the indirect, nondestructive, in-situ measurement of vadose zone soil moisture (θ) are available including: time domain reflectometry (TDR); capacitancebased frequency domain reflectometry (FDR); impedance-based amplitude domain reflectometry (ADR); phase transmission; and time domain transmission (TDT) (Muñoz-Carpena et al, 2005a).…”
