“…These changes are attributable to thick surface mulch formed over the dump surface which creates a cooler soil environment, reduces evapotranspiration, and holds soil moisture by ameliorating the surface temperature. Our results are consistent with the findings of Wang, Liu, Wu, Li, & Wang, (2017).…”

“…The quantity and chemical composition (N concentration and C:N ratio) of the organic mulch residues are variables which determines decomposition rate, predict the amount of potentially mineralizable N (PMN) and nutrients release affecting soil quality (Halde & Entz, 2016;Ibrahim, Abaidoo, Fatondii, & Opoku, 2018;Radicetti et al, 2017). Mulching thickness shows a direct positive effect on soil moisture content and reduces soil surface temperature (Kader, Senge, Majid, & Ito, 2017;Pramanik et al, 2015;Wang et al, 2017). Indirectly, decomposition of litter/organic mulches by microbes also adds to the SOM that simultaneously augments the C and N pools and helps in carbon sequestration (Frouz, 2018;Guoju et al, 2020;Zhang et al, 2019).…”

Dumping of hazardous waste causes land degradation, air, and water pollution, deteriorates landscape and aesthetics, which can be controlled by reclaiming with grass-legume seeding. The study aimed to examine the effect of grass-legume revegetation between 1-and 5-years in a restored waste dump (hazardous waste of an integrated steel plant) reclaimed with coir-matting, topsoil blanketing followed by grass (Pennisetum pedicellatum) and legume (Stylosanthes hamata) seeding. We hypothesized that the synergistic effect of the grass-legume mixture would lead to an increase in productivity and soil fertility. To assess the effects, changes in root and shoot biomass, mulch accumulation, nitrogen (N) mineralization, and its effect on soil fertility were measured. Our results showed between 1-to 5-years legume and grass biomass increased by 44% and 37%, respectively. An increase in mulch density and thickness along with revegetation age potentially increased the soil moisture by 7.5% and lowered soil temperature by 9°C at 10 cm depth. Cumulative N-mineralization by legume was three-fold higher than the grass. Soil organic carbon (SOC), available N, total N, N-stock, and soil respiration was doubled after 5-years of revegetation. Dehydrogenase and urease activity increased by 44% and 56% respectively, indicating greater C and N accumulation at the dump surface. The study concluded that grass (P. pedicellatum) and legume (S. hamata) mixture can be used for reclamation of the waste dump that accelerates recovery of the fertility of disturbed topsoil by contributing mulch with increasing age of revegetation.

“…Mulching is a major practice to reduce soil evaporation, control salinity and increase crop yield (Aragüés et al 2014). Many studies have confirmed the benefits of soil mulching in improving plant growth and yield as well as in modulating the soil physicochemical properties like soil pH, moisture, salinity and sodicity, total porosity, available nitrogen (N) and organic matter (Iiles 1999; Aragüés et al 2014;Ni et al 2016;Wang et al 2017;Qu et al 2019). Mulching is also effective in the modulation of soil bacterial conmunity (Qian et al 2015;Farmer et al 2017;Munoz et al 2017).…”

Mulching has been used widely to improve the production capacity of the soil, yield and the quality of wine grapes (Vitis vinifera L. cv. Cabernet Sauvignon). However, the ecological mechanisms underlying the mulching materials were not well understood. This study aimed to evaluate the effects of different mulching materials on soil chemical properties, bacterial community and wine grape quality. Experiments were performed at a grape-yard on the six-year-old wine grape ‘Vitis vinifera L. cv. Cabernet sauvignon. Five kinds of mulching materials include living turfgrass (Grass), living Herba portulacae (Por), inorganic plastic black film (Film), organic chips of wood (Wood), and grape branches (Branch) were applied, while clean tillage (CK) was treated as a control. Soil chemical properties and grape quality indicators were measured. Soil bacterial community diversity was detected using the Illumina Miseq sequencing for the 16S rRNA gene V3-V4 region. Mulching with plastic film, wood chips and Herba portulacae (Por) increased the content of soil organic matter, available N, P and K, total N and P. Film, grass, branch and Por mulching materials improved the content of tannin, anthocyanin, total phenol and titratable acid in grape (p<0.05). Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria and Gemmatimonadetes were abundant bacteria. Mulching with grape branch and portulacae increased the relative abundance of Gemmatimonadetes and Chloroflexi phylum, Gemmatimonadaceae family, and decreased Micrococcaceae family and Pseudarthrobacter genus. Mulching with living, organic, or inorganic changed chemical properties and grape quality indicators. These changes might be correlated with the altered soil bacterial community diversity and richness. © 2022 Friends Science Publishers

“…The use of mulch to reduce erosion by water in various conditions with reduced average runoff volume sediment, and nutrient loss, in some cases up to 90% in total (Prosdocimi et al, 2016). Amorpha fruticosa, Lespedeza bicolor and Medicago sativa legumes are significantly able to improve the chemical and biological properties of the soil (Wang et al, 2017). The combination of improved soil management and legume planting can reduce soil loss by 99% and nutrient loss by 96% (Machado et al, 2010).…”

Nutrient loss in dry land through surface runoff and soil erosion is thought to dominate the watershed eutrophication. Conservation agriculture is expected to be able to reduce the nitrogen (N) loss into river systems. This study aimed to compare the N total input between conservation and conventional farming systems and to analyze N losses through surface runoff and soil erosion in conservation agriculture compared to conventional farming systems. The study was conducted at Agro-Techno-Park at Jatikerto, Brawijaya University from December 2017 to September 2018. The experiment was designed with three factors, i.e. (1) with and without biogeotextile, (2) No and conventional tillage, (3) application of four kinds of cover crop residues, with three replications. Results of the study showed that conservation agriculture was able to provide higher N inputs into the soil than conventional agriculture. The N loss through surface runoff was relatively low, ranging from 0.03 kg/ha to 0.45 kg/ha. N loss through erosion with conventional tillage and without biogeotextile reached 15 kg/ha to 32 kg/ha. No-tillage practices combined with the biogeotextile application significantly reduce N losses through soil erosion to only 0.3 kg/ha to 5 kg/ha. Conservation agriculture is one of the solutions to overcome the trade-off between the need for increased food production and environmental protection.
