“…The significant pH reduction of SWRs-soil mixtures and leachate (especially in BW) might be due to the acid treatment of carbonization, to microbial CO 2 , and to the release of organic acids with the displacement of exchangeable H + ions to the soil solution (Nelson et al 1998). The obtained results are in accordance with many studies claiming that soil organic amendment leads to a decrease in pH (Bai et al 2013). The increased soil and leachate salinity of the SWRs-amended soil could be due to the organic compounds biodegradation and the release of soluble minerals (Zheljazkov 2005;Bhavsar et al 2016; Ghosh and Devi 2019) which increase electrolytes concentration in the soil solution.…”

Purpose Climate change and global food demand in coming decades urge effective actions for more efficient uses of water and soil resources. This paper reports the preliminary findings of a study assessing the potential of sheep scoured wool residues (SWRs) as soil amendments to enhance the physical and hydraulic properties of a sandy loam soil under rain conditions. Methods Two different SWRs were used: scoured residues (white wool, WW) and carbonized scoured residues (black wool, BW) at different SWRs/soil ratios (0.0, 0.5, 1.0 and 2.0%). Soil bulk density (BD), total porosity (TP), aggregates stability, aggregate size distribution, saturated hydraulic conductivity, and water retention properties were determined under rain conditions, in addition to rainwater balance (storage, percolation and runoff). Results Both WW and BW, particularly at the high wool/soil ratio (2%), significantly reduced soil BD by 11.98% and 9.85%, respectively. Moreover, WW and BW increased TP by 16.45% and 13.57% and available water capacity by 6.5% and 18.1%, respectively. SWRs increased the formation of macro-aggregates and increased aggregate stability. The results of rainwater balance showed higher percolation percentages and less rainwater storage in the wool-treated soil. Conclusions The increase in water percolation is in line with the increased total porosity and the higher saturated hydraulic conductivity of wool-treated soil. Despite the high capacity of absorbing water, SWRs affected the water movement of the soil more than its water retention.

“…Our results underpin many studies which claim that soil organic amendment led to a decrease in pH (Ok et al, 2011;Bai et al, 2013). Moreover, wheat straw contains more cellulosic compounds than cattle manure and various organic acids can be released by cellulose degradation (Shan et al, 2008).…”

A field experiment was performed to examine the effectiveness of adding two kinds of organic materials (wheat Straw and cattle manure) on the soil aggregate stability along a gradient in salinity in the lower cheliff plain (western Algeria). The experiment was set up in a factorial design by complete randomized blocks with three replicates. The treatments were applied at a rate of 4 g C kg -1 soil. One year after organic amendments, mean weight diameter (MWD) was measured using the Le Bissonais method (1996). Other soil properties involved in saline soil aggregation were also measured, namely, electrical conductivity (EC), exchangeable sodium percentage (ESP), pH, cation exchangeable capacity (CEC), porosity, saturated hydraulic conductivity (K sat ), microbial biomass carbon (MBC) and hot water extractable polysaccharide (HWEP). The results demonstrated a significant effect of organic inputs in improving aggregate stability; the effectiveness was related to the type of aggregate stability test that has been used, organic matter type and the level of soil salinity. The wheat straw proved to be more efficient in soil aggregation than cattle manure. Most of the considered soil properties were significantly influenced by organic inputs. Overall, correlation analysis revealed that enhanced microbial biomass was the most important factor in stabilizing soil aggregates (r = 0.72 with MWD MB and r = 0.64 with MWD FW ). Therefore, MWD influences soil porosity (r = 0.67 with MWD MB and r = 0.56 with MWD FW ), which in turn resulted in increased hydraulic conductivity (r = 0.77 with MWD MB and r = 0.87 with MWD FW ).

“…7, due to its atypical evolution from the second to the third sampling campaign with a decrease in pH, an increase in Ca 2+ , and a decrease in SAR. This evolution can be explained in puddled soils by the decomposition of straw, which releases CO 2 and Ca 2+ and decreased sodicity and pH (Bai et al, 2013).…”

Multivariate analysis of soil salination-desalination in a semi-arid irrigated district of Spain

Long-term studies of the changes in soil salinity are scarce and most overlook individual ions. Here, we assess changes in soil ionic contents using 42 soils repeatedly sampled during three campaigns over 24 years in a semi-arid irrigated district. Multivariate analysis (MVA) was used to evaluate the spatial distribution of ions and the temporal changes at comparable soil depths in relation to environmental and management factors. In general, the position of the soil in the landscape governed the spatial distribution of the salinity, while the temporal variations were related to irrigation, with incidences depending on the location in the district. Many soils on the slopes and foothills became salinated during the first years due to land leveling, but salination eventually tapered off after sprinkler utilization. At high and middle elevations, most soils were slightly saline in the first campaign but underwent desalination during the study period. At lower elevations, an initial desalination was followed by a pronounced salination, which was attributed to a water table rise with generalized irrigation in the basin. Whereas univariate salinity assessment might lead to conclusions that are over-simplistic at the landscape scale, MVA detects singular
