Soil spectroscopy is a powerful technique for soil monitoring. Hundreds of soil spectral datasets, both open-access and private, are used for various applications, despite potential errors. This study presents a filtering protocol to enhance the quality of soil spectral datasets from laboratory and satellite sources, here termed the Spectral Quality Protocol (SQuaP). At the beginning,...

Soil Organic Carbon (SOC) stocks in croplands play a key role for climate change mitigation and soil sustainability, with proper management techniques enhancing carbon storage to support these goals. This study focuses on the development of a hybrid carbon modeling approach for the simulation of topsoil SOC stocks across the entire agricultural area of Lithuania....

The variability of soil detachment rate (Dr) with rill length is essential to understand the complex process of rill erosion. Moreover, an important variable of rill erosion, such as the ‘flow sediment deficit’ (FSD)–the difference in Dr between the two extreme points of a rill–has been scarcely investigated. Soil disturbances, such as fire and deforestation,...

Soil has garnered global attention for its role in food security and climate change. Fine-scale soil-mapping techniques are urgently needed to support food, water, and biodiversity services. A global soil dataset integrated into an Earth observation system and supported by cloud computing enabled the development of the first global soil grid of six key properties...

Very few studies have explored the effectiveness of polyacrylamide (PAM) application on soil in mitigating rill erosion, especially in deforested environments. This study has measured the soil detachment capacity (Dc) on samples of deforested soil (untreated or treated with PAM). Dc has been estimated by flume experiments under three bed slopes (6.9%, 17.2%, and 18.2%)...

In arid and semi-arid regions, significant evaporation intensifies water scarcities and soil salinization, imposing severe challenges to agricultural productivity and economic advancement. This study quantitatively assesses the impact of varying soil salinity levels (0 to 1 wt%) and their distribution within the soil column on water, heat, and salt transport dynamics during evaporation. With a series...

This study analyzed the effects of very intense rainfall (98 mm/h for 30 min) on soil left bare or treated with polyacrylamide, rice husk biochar and hydromulching. Rill morphometry, surface runoff and soil loss were measured in plots (100 cm × 50 cm) with three longitudinal slopes (10%, 17% and 28%). On the basis of...

Abstract Soil Organic Carbon (SOC) is a key property for soil health. Spectral reflectance such as multispectral and hyperspectral data could provide efficient and cost-effective retrieval of SOC content. However, constrained by the availability of hyperspectral satellite data, current works mostly use a small number of spaceborne hyperspectral imagery for SOC retrieval on a small...

Rill erosion is the most common form in steep and long hillslopes, but studies about the biochar effects on soil detachment capacity in rills are scarce. This study has simulated soil detachment in rills (Dc) by a laboratory flume on samples collected from forest soils in Northern Iran. The samples were treated with biochars (from...

Soil spectroscopy has emerged as a key technique for rapid, non-destructive soil property prediction, yet the centralized nature of the training of machine learning models raises concerns around data privacy, accessibility, and transferability. This study proposes the application of Federated Learning (FL) as a decentralized approach to soil spectroscopy, enabling collaboration between multiple data contributors...
