Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
Impact of Scots pine admixture in European beech stand on dissolved organic carbon and nitrogen leaching from organic and humic horizons of Dystric Arenosols in Northern Poland
European beech Scots pine leaching carbon cycling nitrogen cycling
2015/4/14
The effect of Scots pine admixture in European beech stand on the leaching of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), nitrate nitrogen (NO3-N) and ammonium nitrogen (NH4-N) f...
Available nitrogen in the surface mineral layer of Serbian forest soils
A-value C/N ratio total organic C total soil N
2015/3/27
Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total o...
Moisture effect on carbon and nitrogen mineralization in topsoil of Changbai Mountain, Northeast China
soil moisture soil C and N mineralization incubation experiment Changbai Mountain Northeast China
2015/3/27
Changbai Mountain Natural Reserve (1,985 km2 and 2,734 m a.s.l.) of Northeast China is a typical ecosystem representing the temperate biosphere. The vegetation is vertically divided into 4 dominant zo...
Atmospheric deposition of nitrogen and sulphur in relation to critical loads of nitrogen and acidity in the Czech Republic
acidity atmospheric deposition
2015/3/3
Estimates of dry and wet deposition of sulphur and nitrogen were compared with critical loads of sulphur
and nitrogen in the Czech Republic on 1 ×1 km grid. Deposition was estimated from monitored a...
Altitudinal gradients of natural abundance of stable isotopes of nitrogen and carbon in the needles and soil of a pine forest in Nepal
pine forest Nepal stable isotopes
2015/1/29
This paper deals with natural abundance of 15N and 13C in the soil and needles of the pine forest (Pinus roxburghii, Sargent) along an altitudinal gradient. The study area lies in the elevation range ...
Biological activity, nitrogen dynamics, and chemical characteristics of forest soils in the Šumava national park
Š umava NP Picea abies soil chemistry
2015/1/29
This paper deals with large-scale mountain forest decline in the Šumava National Park. The changes in biotic and abiotic properties of forest sites follow the tree layer disintegration. Changed m...
Characteristics of Nitrogen Mineralization in the Soil of Japanese Cedar (Cryptomeria japonica) and their Responses to Environmental Changes and Forest Management
forest management nitrification ratios of mineralized to total nitrogen soils of sugi stands
2009/8/28
Knowledge of nitrogen mineralization in the soils of sugi (Cryptomeria japonica) stands is important for understanding the effects of forest management and environmental changes on nutrient cycling in...
The Effect of Treatment for Land Surface during Forest Practice on Soil Nitrogen Dynamics
nitrate nitrification nitrogen cycling scarification soil microbe
2009/8/27
The inorganic nitrogen pool in soil, soil microbial biomass, nitrogen pool in vegetation and microbial nitrogen mineralization in soil were investigated to understand the effect of treatment for land ...
Retardation of Nitrogen Leaching by the NO3– Adsorption in the Subsoil in a Watershed of Old Japanese Cedar and Cypress Stands
anion adsorption column experiment forest cutting subsoils volcanic ash soils
2009/8/25
Volcanic ash soils contain appreciable quantities of anion adsorption capacity (AEC) due to the variable charge, and they adsorb anions by non-specific adsorption. To study the effect of this characte...
