NUTRIENT UPTAKE KINETICS OF CLOUDBERRY
Journal of Plant Nutrition, 2013Mineral fertilization of cloudberry (Rubus chamaemorus) has been inconclusive so far. Nutrient absorption of cloudberry was studied by solution depletion 1) to characterize its nutrient uptake kinetics and 2) to determine its preferred nitrogen (N) form. Two accessions, ‘Fjordgull’ (a female cultivar from Norway) and a local wild clonal selection from ‘

Uptake of Nutrients by Blackgram
MADRAS AGRICULTURAL JOURNAL, 1975Blackgram variety Pusa 1 was grown in a -calcareous red soil of Coimbatore in the pot culture house during.August-November- 1972.Nitrogen was applied as ammonium sulphate at threelevels namely O1 30 and 60Kg N per ha.Phosphorus was applied as P12 labelled superphosphate at four levels namely 0,30,60and 90 kg P2O2 per ha.Two leves of rhizobial ...

Estimating maize nutrient uptake requirements
Field Crops Research, 2010Abstract Generic, robust models are needed for estimating crop nutrient uptake requirements. We quantified and modeled grain yield–nutrient uptake relations in maize grown without significant biotic and abiotic stresses. Grain yield and plant nutrient accumulation in above-ground plant dry matter (DM) of commercial maize hybrids were measured at ...

NUTRIENTS UPTAKES IN HAZELNUT ORCHARDS
Acta Horticulturae, 2010During six years, the yield and nutrients contents in nuts were recorded in two hazelnut orchards of Italy (Langhe, Piedmont). The data show that the fruit mineral composition differs between orchards and, years. As expected, the quantities of extracted nutrients were mainly nitrogen with values at 7.03 kg/ha/year (Montelupo, 2005) up to 31.44 kg/ha ...

Pogonophora: Uptake of Dissolved Nutrients
Nature, 1968THE mechanism by which the marine tube-dwelling worms of the phylum Pogonophora obtain their food has remained obscure since Ivanov1 established that they have no conventional gut. Ivanov concluded that they are filter feeders, utilizing external digestion, while Carlisle2 has suggested that particles are actively picked up by the tentacles of the ...

Hyperkinetic nutrient uptake byCandida intermedia
European Journal of Applied Microbiology and Biotechnology, 1982After pulsing steady state cultures ofCandida intermedia with pure sucrose, or sucrose adequately supplemented with minerals (2–4 g/l), high substrate uptake rates and both an elevated oxygen consumption and CO2-production rate were observed.

1985
It is clear that tapeworms and other gastrointestinal parasites absorb nutrients from their hosts and that such movement of materials from the hosts into parasites is an essential element of host-parasite relationships. In fact, “parasitism” is generally defined, in part, in terms of such movement of materials, for definitions of parasitism often ...

Nutrient Uptake Traits Related to SugarbeetYield
Journal of Sugarbeet Research, 2004The identification of adaptive traits involved in the response of plants to nutritional stress is necessary for maintaining crop productivity at sustainable levels. The objective of this study was to evaluate the relationships among root elongation rate, root/shoot ratio, nitrate and sulfate uptake rate in sugarbeet (Beta vulgaris L. subsp.

Two-Stage Nutrient Uptake Model
1997In the previous model we investigated the chemical reaction that may take place within a cell. In this chapter, we model in more detail the activities of an entire cell that receives nutrients from its envronment, uses these nutrients for growth and maintenance, and then excretes waste products back into its environment.
