Uptake of Nutrients by Blackgram

MADRAS AGRICULTURAL JOURNAL, 1975
Blackgram 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 ...

MODELLING NUTRIENT UPTAKE OF SWEET PEPPER

Acta Horticulturae, 2005
Models simulating dry matter production have been developed for a large number of greenhouse crops during the past decades. This paper describes how plant-nutrient relationships can be incorporated in a model for greenhouse crops, with sweet pepper as an example.

The uptake of nutrients by flax

The Journal of Agricultural Science, 1943
Flax crops from a number of centres in Northern Ireland and in Norfolk have been analysed for nutrient content.Flax removes from the soil about the same amounts of nutrients as an average crop of meadow hay, but more than spring barley and much less than mangolds.There is no obvious relation between percentages of any one nutrient in the crops examined

Nutrient Uptake and Assimilation

2001
It is now over 50 years ago since Hoagland and co-workers reported their fundamental findings on ion uptake by plants (Hoagland 1948). In experimenting with fresh water alga Nitella and the sea water alga Valonia they found that the ion concentrations in the vacuoles of these two algae did not correspond to the concentrations in the respective algal ...

Integumental Nutrient Uptake by Aquatic Organisms

Annual Review of Physiology, 1989
Integumental nutrient transport is a widespread characteristic of soft-bodied marine invertebrates. These processes, which are qualitatively similar to the Na-dependent transporters of intestinal epithelia, have kinetic and energetic characteristics that make them particularly well suited for accumulating materials from the extremely low substrate ...

Mechanisms and Control of Nutrient Uptake in Plants

2003
This review is a distillation of the vast amount of physiological and molecular data on plant membrane transport, to provide a concise overview of the main processes involved in the uptake of mineral nutrients in plants. Emphasis has been placed on transport across the plasma membrane, and on the primary uptake from soil into roots, or in the case of ...

Hardwood Seedling Root and Nutrient Parameters for a Model of Nutrient Uptake

Journal of Environmental Quality, 2001
ABSTRACTUse of mechanistic models is an increasingly accepted way to evaluate complex processes. The Barber‐Cushman model provides a means to simulate nutrient uptake once information on root system characteristics, nutrient uptake, and soil nutrient supply are developed.

The Mechanisms of Nutrient Uptake by Arbuscular Mycorrhizae

2017
Mycorrhizal fungi are one of the commonly occurring living organism in soil facilitating plants in growth, development, stress tolerance, soil pollutants remediation, C-sequestration, food security and agricultural sustainability. Mycorrhizal fungi assist the plants in nutrient absorption by extending mycorrhizal hyphae network beyond the rhizosphere ...

The uptake of inorganic nutrients by heterotrophic bacteria

Microbial Ecology, 1994
It is now well known that heterotrophic bacteria account for a large portion of total uptake of both phosphate (60% median) and ammonium (30% median) in freshwaters and marine environments. Less clear are the factors controlling relative uptake by bacteria, and the consequences of this uptake on the plankton community and biogeochemical processes, e.g.,

Effect of humic substances in nutrient film technique on nutrient uptake

Journal of Plant Nutrition, 1995
Abstract An experiment was conducted to find out how humic substances affected nutrient uptake of plants. The test plants, oregano, thyme, and basil, were grown in nutrient film technique at two pH levels (4.5 and 6.5), in two substrates (peat and perlite), and at three levels of humic substance that was a peat extract (control, low, and high ...
