A three year fertilization experiment was conducted in which nitrogen (N series: 20 g N m−2 yr−1), phosphorus (P series: 4 g P m−2 yr−1) and potassium (K series: 20 g K m−2 yr−1) were added to a mixed vegetation of Erica tetralix and Molinia caerulea. At the end of each growing season the percentage cover of each species was determined. At the end of the experiment percentage cover of each species was found to be positively correlated with the harvested biomass. In the unfertilized control… 
A comparative study on nutrient cycling in wet heathland ecosystems
SummaryThe concept of the relative nutrient requirement (Ln) that was introduced in the first paper of this series is used to analyse the effects of the dominant plant population on nutrient cycling
Organic matter accumulation and nitrogen mineralization during secondary succession in heathland ecosystems.
TLDR
It is proposed that Molinia has a positive effect on the mineralization rate of nitrogen mineralization in communities dominated by Calluna or Erica, whereas losses of nitrogen from the ecosystem appeared to be negligible in Moliniadominated communities.
Effects of liming and fertilization on forage yield and vegetation in dry heath soils from Tierra del Fuego
Abstract The effects of increasing nutrient availability and liming on the growth of Dactylis glomerata and its neighboring vegetation were studied in dry heath communities dominated by Empetrum
Is the relation between nutrient supply and biodiversity co-determined by the type of nutrient limitation?
TLDR
The study shows that patterns found in correlative studies of the relation between plant diversity and soil and vegetation N:P ratio can not be translated into successful experimental manipulations to enhance biodiversity.
Nitrogen and phosphorus in mire plants: variation during 50 years in relation to supply rate and vegetation type
TLDR
The increased N deposition has had its greatest effects on the site types with the highest Sphagnum biomass and peat accumulation rate, and it seems as the increasedN deposition has directly influenced only the growth of the Sphagnu mosses and that the effects of the increased N depositing are indirect.
Aboveground productivity and nutrient turnover of Molinia caerulea along an experimental gradient of nutrient availability
TLDR
It is suggested that there is a trade-off in Molinia between phenotypically determined characteristics which lead to a high productivity and characteristics which reduce nutrient turnover.
The effect of nitrogen deposition on the vegetation of wet heathlands
TLDR
The statistical modelling of joint species abundance is a potentially powerful tool to understand the effect of the alteration of nitrogen dynamics on community composition, and is essential to design management practices aligned with the predicted effects of varying levels of nitrogen deposition on community structure.
Use of nitrogen to phosphorus ratios in plant tissue as an indicator of nutrient limitation and nitrogen saturation
TLDR
It is demonstrated that N:P ratios can be effective predictors of nutrient limitation in upland ecosystems with particular relevance to the continued deposition of elevated atmospheric N and to the diagnosis of nitrogen saturation.
Composition of plant species mixtures grown at various N:P ratios and levels of nutrient supply
Abstract Changes in the relative availability of essential nutrients such as nitrogen, phosphorus, and potassium can be associated with changes in the species composition of wetland vegetation, but

A comparative study on nutrient cycling in wet heathland ecosystems
TLDR
During the last 20 years this replacement of Erica-dominant communities by monocultures of Molinia has been observed in almost all wet heathlands in The Netherlands along with a strong increase in nitrogen availability.

The year-to-year changes in the field-and bottom layers were studied by non-destructive recording of cover percentage on permanent plots in a young Scots pine (Pinus sylvestris) stand, subjected to
The Effects of Competition and Nutrition on the Inter-Relations of Some Wet-Heath Plants
TLDR
Field studies relevant to competition between the species and their responses to nutrition will be described, and in later papers aeration conditions and their ecological effects will be analysed in detail.
GROWTH, PHOSPHATE ABSORPTION, AND PHOSPHORUS CHEMICAL FRACTIONS IN TWO CHIONOCHLOA SPECIES
TLDR
It is concluded that a low phosphorus requirement associated with slow growth is more important than between-species differences in phosphorus metabolism, phosphate absorption, or efficiency of phosphorus utilization in explaining the success of C. crassiuscula and other low-phosphorus-adapted species on infertile soils.
The relationship between nutrient availability, shoot biomass and species richness in grassland and wetland communities
The relationship was studied between shoot biomass, nutrient concentration in the soil and number of species per unit area. The study was carried out in two different parts of the Netherlands, the
Fine-root production, mortality and decomposition in forest ecosystems
TLDR
In future ecosystem studies, there is a need for better estimates of the rates of change in the root systems, rather than solely structural descriptions of them, because fine root production and below-ground turnover exceed levels conventionally expected in forest ecosystems.
Aboveground biomass allocation, leaf growth, and photosynthesis patterns in tundra plant forms in arctic Alaska
TLDR
Gross aboveground carbon allocation, leaf growth, and photosynthesis pattern studies were initiated to develop a quantitative understanding of the functional importance of these particular tundra growth forms and support the generalization that species with an evergreen growth form have lower photosynthesis capacities than species with a perennial graminoid, forb, or deciduous shrub growth form.
DENSITY OF ROOT BRANCHING AS AFFECTED BY SUBSTRATE AND SEPARATE IONS
If the root system is studied in its relation to characteristics of the soil profile, the largest amount of roots per unit of soil volume is generally found in the most fertile layers or spots. This
MINERAL NUTRIENT PATHWAYS IN A MOLINIETUM IN AUTUMN AND WINTER
TLDR
It was found that about 75% of the nitrogen and phosphorus in Molinia leaves was withdrawn before abscission, and that about 90%" of the potassium, calcium and magnesium was returned to the soil by leaching from the leaves.
Interspecific Competition and Niche Differentiation between Plantago-Lanceolata and Anthoxanthum-Odoratum in a Natural Hayfield
TLDR
There was strong intraspecific competition within the populations of both species at the densities in which they occurred and an equilibrium between the two species was established, which indicated a high degree of niche differentiation.
