The efficiency of using nutrients to produce new biomass may be an important adaptation of plants to infertile habitats. We distinguish resource-use efficiency (production per unit resource uptake) from resource-response efficiency (production per unit resource availability) and employ Monod functions to investigate changes in these two efficiencies along resource gradients. The model predicts increasing nutrient efficiency with decreasing nutrient availability or uptake to some optimum… 

Nutrient-uptake and nutrient-use efficiency ofPinus thunbergii Parl. along a topographical gradient of soil nutrient availability

To examine responses of a plant species to nutrient availability, we investigated changes in soil nutrient availability, litterfall production and nutrient content in litterfall along a topographic

Nitrogen response efficiency increased monotonically with decreasing soil resource availability: a case study from a semiarid grassland in northern China

The results show that soil N and water had exerted a great impact on the N efficiency in Stipa species, which may explain the differences in plant productivity on various soils, which will be conducive to the general understanding of the N cycling and vegetation dynamics in northern Chinese grasslands.

Nutrient uptake and use efficiency in co‐occurring plants along a disturbance and nutrient availability gradient in the boreal forests of the southwest Yukon, Canada

Aim In boreal forest ecosystems plant productivity is typically constrained by mineral nutrient availability. In some boreal regions changes in nutrient availability have led to limited changes in

Nutrient efficiency along nutrient availability gradients

A theory of nutrient use efficiency based upon fundamental mass balance is developed, a graphical approach to appropriate testing of alternative hypotheses to avoid problems of autocorrelation in data is presented, and critical areas where experiments must be performed to distinguish among hypotheses are suggested.

On the relationship between nutrient use efficiency and fertility in forest ecosystems

There is, however, no indication that nutrient use efficiency is greater in nutrient-poor ecosystems, and there is little likelihood that such a feedback mechanism plays an important role in ecosystem nutrient cycling.

Nutrient Use Efficiency in Three Fast-Growing Tropical Trees

Although the species converged on the same nitrogen (but not phosphorus) use efficiency, differences in nutrient productivity and nutrient residence time may confer varying abilities to deal with nitrogen limitation.

Forest Productivity and Efficiency of Resource Use Across a Chronosequence of Tropical Montane Soils

ABSTRACT We tested the hypothesis that plants adjust to nutrient availability by altering carbon allocation patterns and nutrient-use efficiency (NUE = net primary production [NPP] per unit nutrient

Scaling plant nitrogen use and uptake efficiencies in response to nutrient addition in peatlands.

The results demonstrate that plants respond to nutrient availability at multiple biological scales, and suggest that N uptake efficiency may be a more representative measurement of plant responses to nutrients availability gradients than plant NUE.

Ecosystem Nutrient Use Efficiency, Productivity, and Nutrient Accrual in Model Tropical Communities

The results indicate that the effect of life-form diversity on ecosystem functioning is not constant and that there may be temporal shifts in the influence exerted by different components of the community, and argue against the simple upward scaling of nutrient use efficiency from leaves and plants to ecosystems.

The hypothesis that NUE increases with decreasing nutrient availability however increasing such efficiency has a cost reflected in reduced productivity was proven and the hypothesis was proven for all expressions of NUE correlating NUE against estimates of soil N or P availability but there were differences between coastal and tableland Eucalyptus forests.

Nutrient Budgets of Marsh Plants: Efficiency Concepts and Relation to Availability

The effects of variable N and P availability on nutrient uptake, nutrient recovery from dying leaves, and biomass production in three species of marsh graminoids were studied, with the conclusion that, as nutrient inputs to an ecosystem increase, nutrient losses from the system and nutrient turnover in the vegetation should also increase.

Nitrogen Availability and Nitrogen Use Efficiency in Loblolly Pine Stands

The effects of nitrogen availability on N cycling and N use efficiency (NUE) were examined in natural and fertilized loblolly pine stands on the upper coastal plain of South Carolina, and concentrations of N in foliage, wood, fine roots, and needlefall increased with greater N availability, while indices of NUE decreased with increased N availability.

The Nature of Nutrient Limitation in Plant Communities

It is suggested that nutrient limitation in communities can be best measured by assessing the plants' response to large nutrient additions that are sufficient to saturate chemical and microbial immobilization processes and still meet plant nutrient requirements.

It is concluded that a high nutrient resorption efficiency is a phenotypic response to low- nutrients environments, especially in low- nutrient environments.

Phosphorus Availability in Acid Organic Soils of the Lower North Carolina Coastal Plain

Natural variations in P availability, the factors controlling P availability in these soils, and the potential for differential nutrient reabsorption by native plants have important implications for the cycling and accumulation of P and N in pocosin and bay forest soils.

Both mineralization and nitrification were highly correlated with humus P content and differences in nitrification among the soils appeared to be related to P04-P supply in the spring and early summer and to NH4-N supply in mid to late summer.

Nitrogen productivity of some conifers

It is demonstrated that the nitrogen productivity decreases predictably as biomass increases probably as a result of the reduction in irradiance as the canopy becomes more dense.
