Heterogeneous co-supplies of phosphorus, sulfur and carbon enhance phosphorus availability by improving rhizosphere processes in a calcareous soil
Phosphorus (P) availability in calcareous soils is limited. Acidifying the soil by adding sulfur (S) or enhancing microbial activity by adding carbon (C) can increase P bioavailability. However, understanding ...

Open AccessOptions to reduce ranges in critical soil nutrient levels used in fertilizer recommendations by accounting for site conditions and methodology: A review
Fertilizer recommendations (FR) to improve yields and increase profitability are based on relationships between crop yields and soil nutrient levels measured via soil extraction methods. Within these FR, criti...

Urban soil phosphorus hotspot and its imprint on tree leaf phosphorus concentrations in the Bei**g region
Rapid urbanization has altered regional nutrient cycles and consequently affected soil nutrient availability for plant growth. This study aims to explore the way in which urbanization shapes the spatial patter...

Open AccessImpacts of harvesting methods on nutrient removal in Dutch forests exposed to high-nitrogen deposition
Forest harvest removal may cause nutrient depletion of soils, when removal of essential nutrients, including nitrogen (N), phosphorus (P), sulphur (S), calcium (Ca), potassium (K) and magnesium (Mg) exceeds th...

Quantification of the contribution of nitrogen fertilization and crop harvesting to soil acidification in a wheat-maize double crop** system
Over fertilization with nitrogen (N) is considered the main driver of agricultural soil acidification in China. However, the contribution of this driver compared to other causes of soil acidification on intens...

Modelling the spatial distribution of livestock in Europe
Livestock remains the world’s largest user of land and is strongly related to grassland and feed-crop production. Assessments of environmental impacts of livestock farming require detailed knowledge of the pre...

Critical Soil Concentrations of Cadmium, Lead, and Mercury in View of Health Effects on Humans and Animals
To assess the impact of elevated concentrations of metals in terrestrial ecosystems, a major distinction should be made in risks/effects of heavy metals related to (i) the soil ecosystem (soil organisms/proces...

Chapter
Impact of Soil Properties on Critical Concentrations of Cadmium, Lead, Copper, Zinc, and Mercury in Soil and Soil Solution in View of Ecotoxicological Effects
Concern about the input of metals to terrestrial ecosystems is related to (i) the ecotoxicological impact on soil organisms and plants (Bringmark et al. 1998; Palmborg et al. 1998) and also on aquatic organisms r...

The Dutch N-cascade in the European perspective
The Netherlands is “well known” for its nitrogen problems; it has one of the highest reactive nitrogen (Nr) emission densities in the world. It is a small country at the delta of several large European rivers....

Uncertainties in the fate of nitrogen I: An overview of sources of uncertainty illustrated with a Dutch case study
This study focuses on the uncertainties in the ‘fate’ of nitrogen (N) in the Netherlands. Nitrogen inputs into the Netherlands in products, by rivers, and by atmospheric deposition, and microbial and industria...
