Soil Organic Carbon and Humus Characteristics: Response and Evolution to Long-Term Direct/Carbonized Straw Return to Field

Agronomy
While numerous studies have examined the effects of direct and carbonized straw return on soil fertility, most focus on short-term impacts. Long-term research is needed to understand how these practices affect soil fertility and organic carbon ...

Unsupervised Cross-Regional and Cross-Year Adaptation by Climate Indicator Discrepancy for Crop Classification

Journal of Remote Sensing
Large-scale model transfer facilitates crop classification in unlabeled sample regions. However, due to the spectral differences in the satellite image time series (SITS) of the same crop type caused by variations in a crop-growing environment between ...

Response of Organic Carbon Components and Stability to Long-Term Application of Low Doses of Biochar and Biochor-Based Fertilizers

Agronomy
Soil organic carbon (SOC) sequestration plays a vital role in sustaining soil productivity and mitigating climate change. Although biochar and charcoal-based fertilizers are known to enhance SOC sequestration, current understanding is predominantly ...

Hobby Farms and Protection of Farmland in British Columbia [PDF]

Agricultural land protection near the urban-rural fringe is a goal of many jurisdictions, and none more so than British Columbia, Canada, which uses a provincial-wide zoning scheme to prevent subdivisions and non-agricultural uses of the land.
