UAV Remote Sensing for Detecting within-Field Spatial Variation of Winter Wheat Growth and Links to Soil Properties and Historical Management Practices. A Case Study on Belgian Loamy Soil

A function of complex interactions between biological elements, physical characteristics, and historic agricultural management, soil organic carbon, nitrogen, phosphorous, exchangeable cations, pH, or soil texture is a product of soil texture heterogeneity, such as soil organic carbon, nitrogen, phosphorous, pH, or soil texture. Mapping can improve crop quality and yield improvement in a management variable zones framework, with crop growth and final yield heterogeneity, as well as quantifying their connection with soil properties. We tested the capability of a multispectral MicaSense u00ae RedEdge-MTM camera sensor embedded on unmanned aerial vehicle to measure winter wheat production in-season. The red-edge NDVI was the most appropriate to track the crop growth throughout the growing season, according to multiple vegetation indices indexed to the plant area index measured in the field. A combine harvester measured the winter wheat's georeferenced final grain yield. The spatial distribution of RENDVI at three phenological stages was mapped and analyzed simultaneously with the yield map, according to the yield map. The CI-forest algorithm's methodology can help ensure a better management of amendment/fertilizer inputs by stressing the most critical parameters that should be considered for site-specific management. We also showed that heterogeneity exacerbated by the soil properties can be described by a crop map early in the season, and that this crop map can be used to optimize soil sampling and thus amendment/fertilizer management.

Characterizing Southeastern Populations Impacted by Wildland Fire Smoke: Implications for Land Management Practices

The human populations that suffer wildland fire smoke in the Southeast are not well represented, particularly when considering the difference between wild and prescribed fire. Further, it is unclear if some populations profit from prescription fire's benefits, while other groups face the air pollution costs. We identify the populations in the Southeast that most often experience wildland fire smoke using spatial analysis of NOAA smoke estimates, spatially-interpolated smoke measurements, MODIS fire detections, prescribed burning records, census demographics, and indicators of ongoing socioeconomic and environmental stress. In this review, the inclusion of U. S. environmental justice indices helps us determine if this environmental stressor is putting more strain on populations that are already stressed. Wildland fire smoke in several parts of the country can inadvertently affect particular population groups, according to the report.

Impacts of Agricultural Management Practices on Groundwater Quality and Quantity in the Santa fe River Basin, Florida

Agriculture has been identified as a key source of nutrients in groundwater, springs, and streams in the Santa Fe River Basin, which overlies the Floridan Aquifer in North Florida, overlying the Floridan Aquifer. The main goals of this investigation are to model the hydrologic system in the Santa Fe River Basin using the Soil and Water Assessment Tool, as well as water discharge and nitrogen load in the Santa Fe River. Three management scenarios were developed to investigate the effect of agricultural management techniques on the quality and quantity of groundwater that feeds the Santa Fe River and its springs.

Contaminant Transport in Heterogeneous Soils from Different Land Management Practices

In the subsurface, the pore structure's intricate pore structures influence how water flow is distributed and, subsequently, how dissolved chemicals are transported. We suspect that the geographic heterogeneity created by differing agricultural land management techniques will influence the transport behavior of agrochemicals in these soils. The velocity field in each soil domain is calculated from the full Navier-Stokes equations, and massless particle tracers are reported accordingly. A statistical review of the Lagrangian tracks is included to compare the velocity distribution, velocity correlation length, breakthrough curve, and evolution of displacement moments that characterize each land management strategy. With a Continuous Time Random Walk modeling system that accurately forecasts large-scale anomalous behavior, we can now refine the pore-scale particle dynamics. Decision makers in agriculture need to implement more effective agricultural practices. An improved understanding of the causes of contaminant transport in agricultural soils and of the analysis of contaminant movement are essential to assisting decision makers in establishing more sustainable agricultural practices.

Integrating agricultural best management practices and engineering technologies for watershed management under the context of Food-Energy-Water systems

The amount of phosphorus recovered from corn biorefinery co-products in the watershed can be higher than the agronomic P requirement, according to the same level of plant-wide revenue, which shows the promise of P circular economy to eliminate the P paradox in the Corn Belt watersheds. We pair ITEEM with a multi-objective optimization scheme to find optimal options for spatially distributed BMPs and EBTs by selecting watershed portfolios consisting of BMPs and EBTs in improving performance of various FEW system metrics. When 1st. biomass market price is 3-fold $ 120 Mg-1 per household per year, it would be economically viable for water quality improvements.

Implementation of Meta(data) Management Best Practices for Environmental Microplastics Data

Although there are many research studies on environmental microplastics analysis and metadata quality, there are no concrete guidance and documents on how to implement these recommendations in practice. As a result, many environmental microplastics reports are not particularly useful for comparative analysis and usage. It is vital that we continue to monitor environmental microplastics data throughout the research project life cycle in order to fulfill FAIR data standards in a rapidly expanding research field. This paper will focus on the steps needed to implement recommended data management best practices for environmental microplastics based on existing literature as well as broad community feedback. We will publish the results gained and lessons learned during our pilot study, in which a standardized set of metadata attributes and persistent identifiers will be applied to environmental microplastics research results in Canada.

Representing silvicultural management practices in SWAT and quantifying their impact on water yield

Managed forests, which account for a large portion of the land area in several watersheds, are a significant part of the land area in many watersheds, and integrated management approaches inherently introduce FSS dynamics in managed forests. The Soil and Water Assessment Tool is particularly useful for determining the hydrologic consequences of land management's hydrologic evaluation. However, since SWATs administration activities are mainly focused on annual crops, it is not possible to simulate multi-decadal forest management methods. Pine species were added to SWAT's plant database and calibrated using various data types. If properly calibrated, production yield results closely matched typical forest product yields for the area, meaning SWAT will accurately simulate managed forests. We also discovered a two-fold variation in water yields across management methods, showing their emphasis on forest hydrology. In SWAT, the general strategy described is not limited to pine plantations and can be used to create other forms of managed forests.

The Responsiveness of Permanganate Oxidizable Carbon to Different Management Practices in Coarse-Textured Soils of Florida

Permanganate oxidizable carbon has become a commonly used way to determine soil C cycling and soil health. This is especially true in soils that differ from the main areas of the United States, where POXC has been promoted as a key soil health indicator, such as Florida, which is dominated by coarse-textured soils and subjected to a subtropical climate. We've compared the response of POXC to management in three separate experiments in order to learn how POXC reacts to various management methods. POXC was indeed responsive to various management techniques within agroecosystems, as it increased 1 after eight weeks of cover cropping with no difference between species or blends in vegetable crops; 2 after the introduction of new manures and composts in an eight-week incubation study.

Assessing the effectiveness of Beneficial Management Practices in improving water quality under changing climate conditions

Beneficial Management Practices are often recommended to enhance water quality in agricultural areas to improve water quality. However, climate change can influence water quality conditions and the effectiveness of BMPs in the future. This report examines BMP's results and recommends new adaption methods in Canada's changing climate. The results of an ensemble of climate models' findings are used to determine optimal combinations of BMPs that can minimize nutrient delivery in the QARB at low cost of implementation in the future time episodes. BMPs' effectiveness has dramatically reduced under changing climate, and the previously found combination of activities under the old climate may no longer reduce nutrients under elevated temperature conditions. This type of research will help decision makers select an appropriate water management strategy in the future, according to changing climate.
