Spectroscopy as a tool for the management of soil acidification
Globally, soil acidity is a significant problem for crop production. It affects both surface and subsurface soils, reduces availability of essential nutrients, increases aluminium toxicity generating yield losses and reduces productivity in agricultural crops. While lime (CaCO3) application is an …

Consequences of nitrogen fertilization and soil acidification from acid rain on dissolved carbon and nitrogen stability in the unglaciated Appalachian Mountains
… is a primary vector of both N fertilization and acidification, initiating a cascade of consequences that alter biogeochemical cycling and global biological structure and function. Studies on N and acid influences are however rarely linked despite their common source. We used a wide, chronic …

The effects of accelerated soil acidification on aggrading temperate deciduous forests: The Fernow Experimental Forest Long Term Soil Productivity (LTSP) Study at 13 years
… I used the Fernow Experimental Forest Long Term Soil Productivity (LTSP) experiment near Parsons, WV to determine how ongoing acidic deposition may affect total ecosystem carbon (C) storage, stand level dynamics, and soil and foliar chemistry in a young regrowing temperate deciduous forest. I …

Farm productivity in the Southern Tablelands - Monaro Region, 1931-85
… in southern Australia since World War II. Soil acidification will soon be severely affecting much of the large areas of improved pastures that began to be established in the bounteous 1950s unless large sums of money and much effort are spent. However, the cost-price squeeze first manifest …

Acidification and eutrophication of forests on sandy soil: effects of forest type and deposition load
Forests on sandy soil did clearly acidify during the past decades, what was found to be related to high depositions of potentially acidifying compounds to the forest floor. Several factors are a stimulus for high atmospheric deposition load in these types of forest ecosystems. (1) Forests are often …

The impact of plantations of Pinus spp. on the chemical properties of soils and stream waters in South African upland catchments
… significant component of the acid load to forest soils and can result in significant decreases in soil pH, acid neutralising capacity and base status. Despite this, the possibility that these processes can result in a significant transfer of acidity to drainage solutions and consequently to …

Sulfate Dynamics and Base Cation Release in a High Elevation Appalachian Forest Soil
Two soils from the Fernow Experimental Forest near Parsons, West Virginia were characterized and evaluated in terms of their susceptibility to enhanced soil acidification via acidic atmospheric inputs. After initial physical, chemical, and mineralogical characterization, the soils were analyzed for …

Biosphere-atmosphere exchange of ammonia from a fertilized corn canopy in Central Illinois
… and it also contributes to eutrophication and soil acidification following wet or dry deposition. Uncertainty in NH3 emissions due to sparse measurements limit the ability of air quality models to predict secondary PM in the atmosphere and depositional loads of nitrogen to ecosystems. To …

Nitrophosphate as an alternative phosphate fertiliser for acidic sandy soils
… (P), which is pre-applied resulted in soil acidification, the accumulation of NH4+ and loss of cations. Nitrophosphate was therefore suggested as an alternative phosphate fertiliser to remedy low P use efficiency, soil acidity and to replace lost calcium (Ca) and magnesium (Mg). A study …

Influence of Poultry Litter on Dark Tobacco Growth and Soil Nutrient Availability
… fertilizers increase the osmotic pressure of the soil solution and soil acidity, often causing reduced stands, Mn toxicity, Mo and Ca deficiencies, and reduced yield and quality of the cured leaf (Sims et al., 1984). Poultry litter utilized as a nutrient source is an inexpensive alternative to …

Assessing the impact of cover crops on soil health in a long-term no-till rotation: a case study from Northeast Kansas
Maintaining soil health is essential for sustaining agricultural productivity and ecosystem resilience. Conservation agriculture, known for minimal soil disturbance and permanent soil cover, offers strategies to address soil degradation associated with conventional management practices like …

Closing the loop: Assessing the viability and environmental risks of human excreta-derived fertilizers in sustainable food systems
… reliance on them can lead to contamination of soil and water. Moreover, their production is energy-intensive and is dependent on non-renewable resources. A sustainable alternative to synthetic fertilizers is the use of human excreta. Human excreta is usually considered a waste product and is …

Rh-Based Catalysis Chemistry of Aqueous-Phase Nitrogen Treatment Reactions
… species contribute towards eutrophication and soil acidification. Catalytic denitrification has emerged as a promising technology for the remediation of nitrogen-contaminated waters. The primary goal of this work is to investigate rhodium (Rh)-based catalysts for the remediation of inorganic …

Nutrient fluxes and soil microbial processes
… to windfall, forest dieback, drought, as well as soil acidification have caused negative ecological impacts in many sites. Conversion of conifers into deciduous or mixed stands has been suggested by some foresters, in order to improve the stability, ecology and biodiversity of forest ecosystems. …

Acid deposition effects on soil chemistry and forest growth on the Monongahela National Forest
… impact forest ecosystems. AD may acidify soils through base cation leaching or Al mobilization, may cause accumulation of nitrates and sulfates in soils, and in some cases has been related to forest decline. The Monongahela National Forest (MNF) lies downwind from many sources of AD …

Determining the spatial and temporal distribution of macro- and microplastics in soil and their impact on soil function.
… or the impact of these interactions on soil function. It was the overarching aim of this project to determine the extent of macro- and microplastics in Scottish surface soils, both spatially and temporally, and evaluate the impact of microplastics on soil function and ecosystem services. …
