“…In agroecological zones in South Asia, there was an analysis of the alternative use of plant residues to increase soil organic carbon, soil moisture, soil nutrients, and soil biological activity by applying biochar and raw agricultural waste generated in the field. The results demonstrated that mulch and biochar 2 improved the production of agroecosystems by up to 64%, and around 1,625 farmers in the region adopted waste management practices in the field, promoting circular agriculture (Dey et al, 2020).…”

“…Many studies worldwide have shown that mulching is a key method for controlling runoff and soil erosion [4,5]. Long-term studies have shown that mulching can improve water use efficiency by increasing soil infiltration, reducing evaporation [6], and reducing soil nutrient loss [7]. Mulching can also reduce soil temperature changes, control weed infestation [8], and increase crop yields [9].…”

Straw mulching is a key method for controlling soil and water losses. Mulching costs may be reduced by applying it in strips rather than over entire areas. However, the effect of different straw mulching methods on the effectiveness of reducing soil erosion is unclear. In this study, the effects of straw mulching strip length (covering 1/4, 1/2, 3/4, and 4/4 of the slope length) and coverage rate (0.2, 0.5, and 0.8 kg m−2) on interception, infiltration, runoff, and soil erosion were investigated at the plot scale using rainfall simulation experiments. The further complex correlations between these variables were analyzed using structural equation modeling (SEM). Bare slopes were used as a control group. The rainfall intensity was chosen to be 60 mm h−1. The results showed that (1) the modified Merriam interception model can describe the change in interception with time under straw mulching conditions well (R2 > 0.91, NSE > 0.75). (2) A total of 35.39–78.79% of the rainwater is converted into infiltration on straw-covered slopes, while this proportion is 36.75% on bare slopes. The proportion of rainwater converted to infiltration was greatest (78.79%) when the straw covered 3/4 of the slope length at a coverage rate of 0.5 kg m−2, which was the most conducive to rainwater harvesting on the slope. (3) Straw mulching protects the topsoil from the impact of raindrops and directly affects the sediment yield (direct effect = −0.44). Straw mulching can also indirectly affect sediment yield by increasing interception, reducing runoff, and decreasing the sediment carrying capacity of runoff (indirect effect = −0.83). Compared with bare slopes, straw covering at least 1/2 of the slope length can significantly reduce runoff yield, but straw covering only 1/4 of the slope length can significantly reduce sediment yield. Moreover, once the straw mulch slope length reaches 3/4 and the coverage rate reaches 0.5 kg m−2, further increases in mulch slope length and coverage rate will not significantly reduce the runoff and sediment yields. These results assessed the effectiveness of different straw mulching methods in controlling soil and water losses on sloping farmland.

“…Therefore, in situ immobilization is now widely used because of its efficiency, cost-effectiveness, and accessibility [12]. Rice straw may be harvested from the field, heaped or distributed, integrated into the soil, or employed as mulch for the indicate [13,14]. For instance, rice straw can be used as a natural fertilizer in fields [15][16][17].…”

Valorization of lignocellulosic rice husk producing biosilica and biofuels—a review

et al. 2022

View full text Add to dashboard Cite

Lignocellulosic biomass is an agricultural waste material abundantly produced in large quantities on earth. Rice husk (RH) is one of the lignocellulosic biomass and a huge byproduct of rice milling. Notably, the rice plant collects silica from the soil and stores the collected silica in the form of silicic acid inside the cellulose micro-compartments of the plant. Therefore, RH obtained from rice milling contains a significant quantity of amorphous silica, which can further be used for several other purposes. Furthermore, Silica-rich RH can be employed as raw material for the production of biofuels and biochars instantaneously via thermochemical processes like pyrolysis, gasification. This article thoroughly explored the prospective method of rice husk use to produce bio silica and energy at the same time, which is currently under investigation. Moreover, this study also discussed current improvements in the synthesis of RH silica materials and their long-term uses, particularly in energy and environmental functional materials. In terms of the environment, RH-silica materials may remove heavy metals and organic pollutants in soil amendment, wastewater treatment, and gas purification via adsorption, catalysis, and integrative methods. In essence, there are numerous research and development obstacles to the production of bio silica and biofuels, respectively, from RH to overcome, and this review article highlights all of them.
