| Abstract |
Alkali soils have undesirable properties for crop production. However, these problematic areas can be reclaimed and regained for cultivation. Mulch materials have been used in the past to decrease salinity damage in saline soils. But information about using mulch materials for alkali soil reclamation is rare. The aim of this study was to determine the combined effects of different levels of gypsum applied with straw or pumice mulch materials on the reclamation of an alkali soil. Results obtained from soil extracts during the leaching water cycles showed that gypsum and mulch materials caused significant differences in sodium adsorption ratio (SAR) and electrical conductivity (EC) values. Major reclamation parameters of soil samples were also determined after the addition of 140 cm of leaching water. The exchangeable sodium percentage (ESP) significantly decreased from 18.43 in the initial soil to as low as 2.31 in 0-15 cm soil depth samples and 10.53 at 15-30 cm (P < 0.05). The various treatments were related to significant decreases in SAR, EC, and lime content in reclaimed soils. The amount of water stable aggregates (WSA) increased significantly after reclamation. Although hydraulic conductivity values also increased, the increase was not statistically significant. The fastest water flow rate was observed in the 100% gypsum requirement (GR) and straw mulch treatment. In contrast, the slowest water flow rate was found in the 50% GR and unmulched treatment, and the differences in means were significant. Overall, the 100% GR and straw mulch treatment was most effective in decreasing soil alkalinity, improving soil structure, and reducing reclamation time. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 May 2018.
All research outputs
#21,358,731
of 23,854,458 outputs
Outputs from Environmental Monitoring and Assessment
#2,266
of 2,748 outputs
Outputs of similar age
#292,143
of 331,583 outputs
Outputs of similar age from Environmental Monitoring and Assessment
#36
of 47 outputs
Altmetric has tracked 23,854,458 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,748 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,583 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 47 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
