Agricultural land use transition

-


 

Agricultural land use transition is a dynamic process influenced by various topographical gradients, including elevation, slope, and aspect, which collectively shape land suitability, productivity, and sustainability. These multidimensional gradients impact how land is utilized, shifting from traditional subsistence farming to more intensive agricultural practices or, in some cases, land abandonment and reforestation. Such transitions have profound effects on ecosystem service interactions, altering the balance between provisioning services (e.g., food and fiber production), regulating services (e.g., carbon sequestration, water regulation), supporting services (e.g., soil fertility, nutrient cycling), and cultural services (e.g., landscape aesthetics, traditional knowledge). In mountainous and hilly regions, for instance, steeper slopes may experience increased soil erosion and reduced agricultural viability, prompting land conversion to agroforestry or conservation-oriented practices. Conversely, gentle slopes and valley regions often support intensified agriculture, leading to potential trade-offs such as biodiversity loss and water pollution. Understanding these interactions is critical for designing sustainable land use policies that optimize ecosystem services while mitigating negative environmental impacts. Integrated land management approaches that account for topographical variability can help balance agricultural productivity with ecosystem health, ensuring long-term resilience and sustainability.

Linking Soil Properties and Bacterial Communities with Organic Matter

-
       Vegetation succession plays a crucial role in shaping soil properties and bacterial communities, ultimately influencing organic matter carbon dynamics. As plant communities evolve, they contribute varying amounts of organic inputs such as root exudates and leaf litter, which alter soil physicochemical characteristics, including pH, nutrient availability, and moisture content. These changes, in turn, influence microbial diversity and composition, as bacterial communities adapt to the shifting soil environment. Soil bacteria play a vital role in organic matter decomposition, carbon sequestration, and nutrient cycling, thereby regulating carbon fluxes in the ecosystem. Understanding the intricate relationships between soil properties, microbial communities, and organic matter carbon during vegetation succession is essential for predicting ecosystem carbon storage potential and designing sustainable land management strategies. #SoilProperties #BacterialCommunitie...

N2O Emissions from Soil in Tomato Production

-
     The application of biochar, biogas slurry, and dicyandiamide (DCD) in soil management plays a significant role in mitigating nitrous oxide (N₂O) emissions while enhancing soil fertility and crop productivity. In protected tomato cultivation, these amendments influence nitrogen dynamics and microbial activities, directly affecting greenhouse gas emissions. Biochar improves soil structure, enhances water retention, and provides a stable carbon source, leading to reduced N₂O emissions by promoting complete nitrification and denitrification processes. Biogas slurry, a nutrient-rich organic amendment, supplies readily available nitrogen for plant uptake, reducing nitrogen losses and gaseous emissions. Meanwhile, DCD, a nitrification inhibitor, slows down the conversion of ammonium to nitrate, effectively minimizing N₂O production. The combined use of these amendments has shown promising results in maintaining soil health, increasing nitrogen use efficiency, and reducing t...

Trade-off between organic and inorganic carbon in soils under alfalfa-grass-cropland rotation

-
        The trade-off between organic and inorganic carbon in soils under an alfalfa-grass-cropland rotation is influenced by land management practices, soil properties, and carbon cycling dynamics. Organic carbon, primarily derived from plant residues and root exudates, enhances soil fertility, microbial activity, and water retention. In contrast, inorganic carbon, mainly in the form of carbonates, contributes to long-term carbon sequestration but has limited benefits for soil fertility. The rotation of alfalfa and grasses with cropland affects the balance between these carbon forms by influencing decomposition rates, microbial activity, and soil pH. While alfalfa and grasses enhance organic carbon input through biomass accumulation and root turnover, cropland phases may accelerate organic carbon mineralization due to tillage and reduced plant cover. Proper management strategies, such as reduced tillage, cover cropping, and optimized fertilization, can help maintai...
