Foliar nutrient dynamics and nutrient use efficiency in Cornus florida

Oecologia, 1985
Growth rates and seasonal changes in foliar nitrogen, phosphorus, and calcium of Cornus florida L. (flowering dogwood) individuals were determined in three forest stands which differed in soil moisture and soil nutrient availability. Nutrient use efficiency of individual trees was measured by amount of leaf dry mass produced per unit nutrient invested,

Foliar absorption and transport of inorganic nutrients

Critical Reviews in Plant Sciences, 1986
All plant cells — those of roots, leaves, or other parts — are capable of absorbing water and solutes as well as gaseous substances. This trait, derived by terrestrial plants during evolution from their ancestral aquatic habitat, is exploited in many agronomic practices.

The Mauna Loa environmental matrix: foliar and soil nutrients

Oecologia, 1992
The accumulation of total carbon, nitrogen, and phosphorus in soils, available soil nutrients, and foliar nutrients in the native dominant Metrosideros polymorpha were determined across a wide elevational range on 9 lava flows on Mauna Loa, Hawai'i. The flows included a young (2800 y) áá (rough surface texture) and pāhoehoe (smooth) flow on the wet ...

Resorption of foliar nutrients in a regenerating southern Appalachian forest

Oecologia, 1987
Leaves were sampled in a successional, southern Appalachian forest to estimate autumn foliar nutrient dynamics. Resorption of N and P in a successional forest equaled, or exceeded, resorption estimates for a more mature control forest. Foliar nutrient leaching was not sufficient to account for changes in autumn leaf N, P, Ca and Mg concentrations.

Effects of Preventing Nutrient Resorption on Plant Fitness and Foliar Nutrient Dynamics

Ecology, 1992
To determine whether autumnal nutrient resorption contributes significantly to plant fitness, resorption was prevented by defoliating scrub oak (Quercus ilicifolia) plants ("defoliate plants") just prior to the onset of foliar senescence in the years 1985 through 1987.

Physiology of foliar uptake of inorganic nutrients

Proceedings / Indian Academy of Sciences, 1986
The leaves of terrestrial plants are capable of absorbing nutrients supplied in an aqueous medium. This capacity is exploited in many agronomic practices like application of herbicides, growth regulators and inorganic nutrients, for the purpose of enhancing crop production.

Effects of Foliar Nutrient Application on Highbush Blueberries

Journal of Small Fruit & Viticulture, 1995
Abstract The influence of foliar applied urea and KNO3 on shoot N status was determined, along with the absorption of foliar applied NO3-N by leaf tissue and it's subsequent translocation to other parts of the plant. The effect of foliar N applications on berry yield, quality, and leaf N levels was also measured in the field.

Assessing the seasonality of foliar nutrient concentrations in woody plants

Ecology
AbstractSeasonal variations in foliar nutrient concentrations are an important strategy of plants to adapt to different climates and availabilities of soil nutrients. Gaps in our knowledge, however, remain in both the seasonality of the concentrations of multiple nutrients in plant leaves and their spatial pattern on a large scale.

Development of Standard Concentrations of Foliar Nutrients for Saskatoon

Journal of Plant Nutrition, 2006
ABSTRACT Soil and foliar samples were collected from saskatoon orchards in Saskatchewan, Manitoba, and Alberta, Canada from 1997 to 1999 and analyzed for macro- and micronutrient content. Foliar samples were collected twice a month from the end of May until September in 1997 to examine the pattern of change in foliar nutrient concentrations throughout ...
