Nutrient pool and main input pathways of forest soils in the central Qilian Mountains, northwest China
Background and aims
Forest ecosystems, serving as critical nodes in global biogeochemical cycles, sustain productivity by modulating nutrient availability. However, the pools of nutrients which modulate tree growth and soil function remain unknown, particularly with regard to their input pathways into forest soils.
Methods
We quantified Calcium (Ca), Iron (Fe), Potassium (K), Magnesium (Mg), Manganese (Mn), and Sodium (Na) concentrations and pools in central Qilian Mountain forest soils (northwest China), with horizon-specific accumulation assessed via Enrichment Factor (EF). Predicted nutrient increments (n-year) and use efficiency (NUE) were modeled to estimate soil enrichment dynamics from atmospheric and litter inputs.
Results
The results indicated that these nutrients can leach into deeper horizons and accumulate in mineral horizons. The total pools of Ca and Fe (3.08 × 103 and 4.43 × 103 t) in forest soils of the catchment were the highest, whereas the Mn and Na pools (95.8 and 92.8 t) were the lowest. The EFs of nutrients were highest in moss and litter horizons. The concentrations of Ca, Fe, K, Mg, and Mn in forest soils will likely increase rapidly in the next 30 years due to the impact of atmospheric deposition.
Conclusions
We conclude that litter inputs more Ca than atmospheric deposition, while atmospheric deposition inputs more Fe, K, Mg, Mn, and Na than litter. Our findings enrich the research on biogeochemical cycle of elements in forest ecosystems of the Qilian Mountains.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
