“…Mean readily and potentially available Fe rose from 12 mg kg −1 in the interspace soil to 16.4 mg kg −1 in the soil beneath canopies (data not shown). Khanmirzaei et al (2011) reported that OM content and DTPA-extractable Fe increased in the soil under plant canopy. An increase in exchangeable Fe due to the higher OM content of topsoil has been reported by Walna et al (2010).…”

“…Khanmirzaei et al (2011) investigated the influence of floodwater-irrigated eucalyptus plantation on some soil properties and observed that organic matter (OM) content and diethylenetriamine pentaacetic acid (DTPA)-extractable iron (Fe) and manganese (Mn) have been increased under the plant canopy. Karim et al (2009) investigated the effect of canopy cover of some shrubs on soil characteristics and found that in the soil under canopy moisture and OM contents increased but pH value decreased.…”

“…This is probably due to poor vegetation cover (observed in-field, 1 (a, b). In order to stabilize and increase the infiltration rate in the FWS systems, indigenous trees adapted to this environment have been tested, but as their growth is too slow, two species belonging to the exotic genera (Eucalyptus and Acacia) have been experimentally planted, mainly in AR 1, along with three indigenous trees and bushes (Khanmirzaei et al, 2011). The trees were planted on plots of 4 × 4 m spacing covering about 15 % of AR 1 and also behind each embankment in the entire area of AR 1 and part of the area of AR 2 in 1986 (Fig.…”

Estimating the change in groundwater recharge from an introduced artificial recharge system is important in order to evaluate future water availability. This paper presents an inverse modeling approach to quantify the recharge contribution from both an ephemeral river channel and an introduced artificial recharge system based on floodwater spreading in arid Iran. The study used the MODFLOW-2000 to estimate recharge for both steady and unsteady-state conditions. The model was calibrated and verified based on the observed hydraulic head in observation wells and model precision, uncertainty, and model sensitivity were analyzed in all modeling steps. The results showed that in a normal year without extreme events the floodwater spreading system is the main contributor to recharge with 80% and the ephemeral river channel with 20% of total recharge in the studied area. Uncertainty analysis revealed that the river channel recharge estimation represents relatively more uncertainty in comparison to the artificial recharge zones. The model is also less sensitive to the river channel. The results show that by expanding the artificial recharge system the recharge volume can be increased even for small flood events while the recharge through the river channel increases only for major flood events

“…Land degradation has emerged as an environmental crisis, which continues to threaten the lives and livelihoods of many people worldwide. Improper land use, drought, vegetation loss, soil erosion are the principal agents (Lal, 2004;Khanmirzaei et al, 2011;Zhang et al, 2017) and soils play a central role in protection and regulation of land resources. Degradation of soil quality is manifested through water and wind erosion, organic matter and nutrient depletion, soil compaction, soil acidity, and decreased microbial activity (Bezdicek et al, 2003).…”

Land degradation is a major issue in the West African Sahel for human livelihoods. A better understanding of soil and water conservation practices" effects on soil nutrients is necessary for their further development. A study was conducted on encrusted sealed bare Luvisols in Central and Northern Burkina Faso to assess the effects of half-moon (HM), subsoil tillage (ST) and zaï system (Zaï) on soil physical, chemical and biological proprieties. Soil texture was significantly affected by techniques resulting in fines particles particularly in HM system and in ST in a lesser extend. HM technique followed by ST and Zaï, contribute significantly to enhance total organic carbon, total nitrogen, calcium, magnesium, phosphorus and soil pH as well as soil microbial biomass and basal respiration. Soil microbial biomass and basal respiration were significantly (p<0.05) correlated with clay fraction, Soil Organic Carbon (SOC), total N, pH and calcium. These results suggest that the techniques alter soil nutrient and that SOC, pH and phosphorus are mitigating factors that affect the microbial activities. Among the studied techniques, HM system proved to be better in terms of enhancing soil proprieties. Therefore, it may serve as a useful and inexpensive approach to rapidly reclaim degraded soils.
