Special Issue Information

Dear Colleagues,

Agricultural systems (agrosystems) play a crucial role in global food security and economic development. However, soil erosion and associated nutrient losses represent challenges in this context, with far-reaching consequences for soil quality, agricultural productivity, and the environment. Therefore, it is of great significance to conduct precise assessments of soil erosion and nutrient loss in agricultural systems. These help us understand the status of soil degradation and ensure the long-term productivity of the soil, thereby enabling adjustments to fertilization strategies, reducing costs and environmental pollution. Such assessments are also conducive to the formulation of land use policies to promote the green development of agriculture.

This Special Issue is dedicated to compiling research on the assessment of soil erosion and nutrient losses in different typical agrosystems. This topic is within the scope of Agriculture, a suitable journal within which to publish cross-disciplinary international academic papers on soil erosion and agroecology.

For this Special Issue, we welcome both original research and review articles that address soil erosion process and nutrient migration mechanisms, the environmental, agronomic management and climate impacts associated with agricultural systems, and the monitoring technologies including but not limited to in situ monitoring, nuclide tracing technique, erosion models, unmanned aerial vehicle remote sensing technology, and laser scanning.

The erosion plot method (EPM) is the most accurate method for measuring total runoff and soil loss in the field, but it is expensive, time-consuming, and tedious to use, thereby limiting the scope of soil erosion research. Alternatively, the fractional method (FM) involves measuring a portion of total runoff and soil loss to estimate the total erosion. Although the FM may be easier to use in rainforest agroecology, it has not been evaluated under vetiver grass technology (VGT). Thus, a 2-year field study was conducted to verify the efficacy of the FM under VGT by comparing soil nutrient erosion between the FM and the EPM on two slopes (5% and 10%). Three piped drums (left, central, and right) were used to collect total runoff under the EPM, while only a central piped drum was used under the FM (usual practice). The FM’s runoff and soil loss values were similar to those under the EPM (R2 = 0.98–0.99; p < 0.001). Runoff nutrients (R2 = 0.90; p < 0.001) and eroded nutrients (R2 = 0.97; p < 0.001) from the FM were highly similar to those of the EPM on the 5% slope. Similarly, runoff nutrients (R2 = 0.86; p < 0.001) and eroded nutrients (R2 = 0.95; p < 0.001) from the FM were strongly similar to those of the EPM on a 10% slope. The FM accounted for 92% of the total nutrient erosion measured by the EPM under VGT management. Thus, the FM will make research more efficient, cost-effective, and attractive, particularly in large-scale water erosion studies. Full article
