Effects of Forest Harvesting Operations on the Recovery of Earthworms and Nematodes in the Hyrcanain Old-Growth Forest: Assessment, Mitigation, and Best Management Practice

Good soil restoration techniques can be used to determine the right soil amendment techniques to improve the properties of degraded forest soils by focusing on soil organisms. Hence, the present research sought to examine the effects of tree litter of various species on soil organisms recovered from skid trails over a 20-year period after harvesting operations. In the mixed beech litter treatment, the highest incidences of earthworm density, earthworm biomass, and total nematodes were found 20 years after harvesting operations, relative to other litter treatments. With decreasing traffic volume from high to low, soil organisms' presence increased, and soil nematodes' highest values were attributed to low traffic density, earthworm biomass, and soil nematodes.

Prioritization of Susceptible Watershed to Sediment Yield and Evaluation of Best Management Practice: A Case Study of Awata River, Southern Ethiopia

Soil erosion is now a global problem that causes land degradation and long-lasting challenges in Ethiopia. The watershed's characteristics, such as land cover, soil type, and slope, are all thought to be the contributors of soil erosion in the basin. NES = 0. 69, RSR = 0. 58, RSR = 0. 58, and PBIAS = 5. 6 for validation of sediment distribution, with R2 = 0. 69, NES = 0. 66, RSR = 0. 58, and PBIAS = 5. 6 for validation of sediment distribution. The first twelve upstream subwatersheds were identified as being soil erosion-prone areas by the established spatial distribution of sediment yield. Following an analysis of the four most popular BMPs, it was discovered that parallel terracing was the most effective soil erosion removal option in all critical subbasins found in the watershed.

Effects of Different Spatial Configuration Units for the Spatial Optimization of Watershed Best Management Practice Scenarios

Different spatial arrangements of several best management practices at the watershed scale may have dramatically different environmental impact, economic success, and practicality for integrated watershed management. Several different types of spatial configuration units, which have evolved from the spatial isolation of a watershed at different levels and used to assign BMPs spatially to create a single BMP scenario, have been suggested for BMP scenarios optimization, such as the hydrologic response unit, etc. Consequently, the spatial configuration units that support expert knowledge regarding BMPs' spatial relationships and spatial positions along a hillslope are considered to be the most effective spatial configuration units for BMP scenarios optimization, particularly when slope position units are integrated with study of BMPs' spatial coordinates.

Assessing biogeochemical effects and best management practice for a wheat–maize cropping system using the DNDC model

Contemporary agriculture is transitioning from a single-goal to a multi-goal project, which in turn requires selecting the best management method based on an investigation of the biogeochemical effects of management alternatives. Among potentials, the bottleneck is the capability of predicting the simultaneous effects of various management practice scenarios on various targets and choosing BMP among scenarios. If nitrogen dose was reduced by 15% or irrigation water amount was reduced by 25%, Crop yields were barely reduced. Two techniques were used to identify BMP and resulted in the same BMP, which adopted the latest crop cultivar, field operation schedules, and complete straw incorporation, as well as applied nitrogen and irrigation water at 15 and 25 percent lower rates, respectively, than the previous use. The DNDC model can be used to determine biogeochemical effects of management choices and identify BMP, according to our report.

Agricultural Best Management Practice Abundance and Location does not Influence Stream Ecosystem Function or Water Quality in the Summer Season

The relationship between BMPs and aquatic ecosystem function is unclear, although best management techniques are commonly used to reduce negative effects of agriculture on water quality. During the summer season, our results show that BMPs in the studied agricultural catchments are not improving water quality or mitigating water quality impacts on stream metabolism. During the summer season, we recommend that seasonality of catchment hydrology and time lag effects associated with previous agricultural land use mask the BMPs' mitigation benefits on stream ecosystem conditions.

Effect of Sediment Accumulation on Best Management Practice (BMP) Stormwater Runoff Volume Reduction Performance for Roadways

Best management techniques are often used to minimize the adverse effects of post-construction runoff. BMP degradation occurs over time as BMP degradation occurs over time, and the infiltration rate decreases as a result of sediment removal. The aim of this paper was to investigate the effect of sediment buildup on BMP stormwater runoff volume reduction results. In this report, a minimum sediment buildup of 0. 22 kg/m2u00b7year was considered. According to the results, the infiltration trench had 100% runoff reduction capability in both conditions, including high-intensity rain and 10-year-old BMP age.

The effects of riparian forest management on the freshwater environment: a literature review of best management practice

The establishment of riparian buffers is required to help prevent the freshwater environment from disturbance by silvicultural activities on the adjacent land. The riparian buffer's main functions are considered to include sediment removal and erosion control, surveillance of water quality, moderation of shade and water temperature, maintenance of habitat ecological diversity and ecological integrity, and landscape enhancement. It's not possible to decide on a narrower riparian buffer width that would shield the freshwater environment from every potential threat. The benefits are greatest where the riparian buffer recreates native riparian woodland with an open canopy of mixed species of varying age classes, as shown by the riparian buffer. Within the care of riparian woodland, a streamu2019s sensitivity and intrinsic value must be considered.

Mulching as best management practice to reduce surface runoff and erosion in steep clayey olive groves

In an olive grove of Southern Italy, the saturated hydraulic conductivity, surface runoff, and soil erosion at plot scale has been studied over two years, total soil cover with a net, mechanical tillage, and mulching by vegetal residues, reducing the soil cover by a net, a net, and soil erosion under rainfall in a two-year study. In SP, NTR1750 and NTR350, respectively, the vegetal cover was on average higher in SP, NTR1750, and NTR350, but lower in MT. The mean organic matter content of soil was 2. 1%, 1. 3 percent, and 0. 8 percent in NTR1750, NTR350, SP, and MT respectively, in total, the results quantify the effect of soil mulching with pruning residues in Mediterranean olive groves, determining the associated socioeconomic and economic benefits.

Improving Best Management Practice Decisions in Mixed Land Use and/or Municipal Watersheds: Should Approaches Be Standardized?

The United States Clean Water Act defines best management practices as those or steps that have been proven to be effective in shielding a given water source from nonpoint source pollution. The aim of this briefing is to introduce a generalized yet integrated and flexible BMP decision-making process to encourage decision makers to more actively work towards the establishment of standardized approaches to BMP monitoring and validation in mixed-use and/or municipal watersheds. BMP implementation and monitoring are two aspects that should be considered when planning BMP adoption.
