We are exploring the impacts of changes in water inputs on soil redox fluctuations and associated biogeochemistry.
Further, our research illustrates the need to consider varying responses among different tree species when predicting future consequences of N inputs on soil C storage.
The effects of nutrient and organic inputs on soil organic carbon (SOC) and total nitrogen (TN) stocks were studied in three 23 25-year-old 23 25-year-old 23 25-year-olde fertility experiments (LTFEs) in the Nepal terai.
We conducted an outdoor mesocosm experiment to investigate the relative impact of above and belowground tree inputs on soil nematode trophic composition, and examine whether tree-driven impacts differed between contrasting species (birch and pine).
In this study we investigated historical charcoal production sites in Germany that have not been in use for > 60 years, and evaluated the effects of the former charcoal inputs on soil and vegetation parameters relative to those of adjacent, unamended areas.
However, as it was beyond the scope of this study to assess the impacts of high intermediate inputs on soil, water, and air quality, we lack full understanding about potential environmental trade-offs, particularly at the field level.
Supply input information on soil and crop management that is representative of each management unit (e.g. test soil and manure based on representative samples, keep good records of operations, estimate expected yield as the second-highest out of 5 years of accurate yield information).
The vegetation transition at treeline provides an opportunity to test the effects of vegetation, topography, and external inputs on soils at three spatial scales.
Concentration of Cd was higher in S-5 followed by S-4, S-3, and S-2 (0.2 ± 0.03 μg g−1) showing the ranking order of S-5 > S-4 > S-3 > S-1 > S-2, which is attributable to spatial difference in fertilizer broadcasting and consequential input on the soil surface.
