“…The coefficients of the proposed regression models must be experimentally calibrated in soils of noticeably different slopes, but the prediction accuracy of these models (and thus their applicability) should not be significantly different. Our findings are in accordance with the study by [72], who showed that models based on simple linear functions of soil covers (straw mulch) can reliably predict runoff and erosion (although these authors worked in a different environment and in soil conditions not affected by fire). In contrast, [38] have demonstrated in similar experimental conditions as this study (pine forests of SE Spain treated with prescribed fire) that accurate simulations of runoff volumes by linear regression models require precipitation data as input.…”

Several studies have analyzed the changes in individual soil properties and covers and quantified the hydrological response of burned forest soils (with or without post-fire treatment). Less research exists on the influence of these changes on runoff and erosion rates immediately after a prescribed fire and post-fire treatment. Moreover, hydrological modeling of burned areas is based on complex models rather than relying on simple regression equations. This study carries out a combined analysis of the hydrological response of soil and its driving factors in three forests (pine, oak, and chestnut) of Southern Italy that were subjected to prescribed fire and post-fire treatment with mulching. Moreover, simple regression models based on a limited set of soil properties/covers are proposed to predict runoff and erosion. The Principal Component Analysis has shown that the runoff coefficients increase when the water infiltration rate and litter cover decrease and repellency, ash cover, organic carbon content, and bare soil area increase. All the analyzed variables play a secondary role in influencing the sediment concentration. Due to these properties, clear differences in soil properties and covers have been found between unburned and burned soils. The distinctions between the burned soils (mulched or not) are much lower. The proposed regression models use a very low number of soil covers and two dummy variables as input parameters. These models are very accurate in simulating the surface runoff and soil erosion in all soil conditions in the short term.

“…Recently, application of RS in agricultural soil is being promoted as a sustainable source of OC (Tandon et al, 2019). It is being used by mulching, composting, or with gypsum in sodic saline soil for reclamation (Ibrahim, Mahmoud, & Ibrahim, 2020;Parhizkar et al, 2021). In the present study, it was observed that the improvement of soil properties by TrichoRS was at par with the FYM and much better than application of gypsum and NPK.…”

Trichoderma‐primed rice straw alters structural and functional properties of sodic soil

Sodic soil is increasing due to intensive cropping and imbalanced use of agrochemicals. Therefore, the objective of the present study was to reduce the soil sodicity in agricultural fields using sustainable resources. The 'microbe-residue-soil' interaction is hypothesized to foster the structural and functional changes during sodic soil reclamation. To elucidate the hypothesis, rice straw (RS) assimilation in sodic soil was instated in the presence of synergistically interacting Trichoderma koningiopsis NBRI-PR5 (PR5) and T. asperellum NBRI-K14 (K14) consortium. The interaction of the 'microbe-residue-soil' was investigated in-vitro and in sodic fields. Our studies included estimation of soil physicochemical properties, enzymes, CO 2 efflux using LI-COR, microbial population, scanning electron microscopy, and Fourier-transformed infrared spectroscopy (FTIR) analysis. The compatibility and synergism of PR5 assisted the K14 to produce laccase enzyme at high pH condition (pH 8) to degrade RS in sodic soil. For in vitro and field applications, Trichoderma were colonized on RS (TrichoRS) and applied at 25 t ha À1 . Impact of TrichoRS on soil was evident from decreased soil pH (9.6 to 7.8), exchangeable sodium percent (19.6 to 9.9%), increased soil porosity (~53% from 38%), and cation exchange capacity (~twofold). The FTIR showed differences in the stretching of O-H bonds at 3750-34500 cm À1 indicating the presence of more kaolinite-type silicates after TrichoRS amendment. Field application of TrichoRS increased the total organic carbon and water-holding capacity from 0.37% to 1.3% and 34% to 57%, respectively. Increased microbes and urease, protease, and phosphatase activity by 2.72-, 0.94-, and 0.88-times, respectively, ensured nutrient availability. The improved soil properties and ~30% increased production justify the hypothesis in providing sustainable reclamation solution for reviving fertility of sodic and intensively cultivated fields.

“…The magnitude of runoff that occurs indicates a volume of rainwater that is no longer infiltrated into the soil and flows freely on the soil surface. A greater value indicates a greater volume of water that flows to lower regions [9]. Based on the overall results for runoff, it was found that the largest runoff of 1.667 l/min occurred for land with rice straw mulch, rainfall intensity of 1.7 l/min, and slope gradient of 15%.…”

Installation of mulch on agricultural land, besides reducing weed growth, can also protect the soil surface from rain and erosion. This study aims to determine the effectiveness of rice straw mulch in reducing surface runoff and soil loss before entering the river. The experimental soil materials were similar to those in Sumber Brantas village, Bumiaji Sub-District, Batu. Runoff modelling utilized the Armfield S12 Rainfall Simulator - Advanced Environmental Hydrology System, with rainfall of 1 and 1.7 l/min. Land with rice straw mulch was compared to land without mulch. The land slope was adjusted to study area conditions, with mild (9%) and steep (15%) slopes. The three-Way ANOVA method was utilized for statistical analysis. In all the experimental runs, it was found that straw mulch effectively reduced the sediment yields that could enter the river area by more than 50%. The results of ANOVA analysis on sediment yield also showed that the significance value of the interactions between slope, rain intensity, and mulch usage was 0 (p<0.05). These results show that the difference in variations in these three factors determines the sediment yield that occurs. In the future, comparing straw mulch with other materials to cover agricultural land should be conducted.
