Effects of Drought on Nutrient Uptake and the Levels of Nutrient-Uptake Proteins in Roots of Drought-Sensitive and -Tolerant Grasses

Plants, 2018
Climate change will increase drought in many regions of the world. Besides decreasing productivity, drought also decreases the concentration (%) of nitrogen (N) and phosphorous (P) in plants. We investigated if decreases in nutrient status during drought

Dynamic model of flexible phytoplankton nutrient uptake [PDF]

Proceedings of the National Academy of Sciences, 2011
The metabolic machinery of marine microbes can be remarkably plastic, allowing organisms to persist under extreme nutrient limitation. With some exceptions, most theoretical approaches to nutrient uptake in phytoplankton are largely dominated by the classic Michaelis–Menten (MM) uptake functional form, whose constant parameters cannot account for the ...

HUBUNGAN ANTARA SIFAT KIMIA TANAH DENGAN SERAPAN HARA TANAMAN TEH DI PTPN VI JAMBI

JTSL (Jurnal Tanah dan Sumberdaya Lahan), 2022
Healthy soil could support plant growth by optimizing the availability of nutrients. The availability of nutrients influences the health of tea plants. Nutrient deficiencies would affect the plant physiology that exhibits the plant withering. This study

Macro- and micro-nutrient uptake pattern and their use efficiencies for maize (Zea mays) in maize-wheat (Triticum aestivum) cropping system under nutrient omissions

The Indian Journal of Agricultural Sciences, 2020
A 2-year (2012 and 2013) field experiment was conducted at ICAR-Indian Agricultural Research Institute, New Delhi to assess the effect of omitted nutrients on nutrient concentration and uptake and (nutrient use efficiency) NUE for maize (Zea mays L.) in ...

Response mechanisms of 3 typical plants nitrogen and phosphorus nutrient cycling to nitrogen deposition in temperate meadow grasslands

Frontiers in Plant Science, 2023
The increase of nitrogen (N) deposition and the diversity of its components lead to significant changes in the structure and function of temperate meadow steppe, which could affect plant nutrient uptake, nutrient resorption and litter decomposition, thus

Optimal uptake kinetics: physiological acclimation explains the pattern of nitrate uptake by phytoplankton in the ocean [PDF]

, 2009
Phytoplankton supply the base of the marine food web and drive the biogeochemical cycles of carbon and nutrients. Over much of the ocean, their growth is limited by their uptake of nitrogen (as nitrate), which has most commonly been described by the ...

Effect of Substrate Flow Rate on Nutrient Uptake and Use Efficiency in Hydroponically Grown Swiss Chard (Beta vulgaris L. ssp. cicla ‘Seiyou Shirokuki’)

Agronomy, 2021
Unlike in soil culture, a substrate (nutrient solution) in a hydroponics system can flow, and this can affect both nutrient uptake and plant growth. In this study, we hydroponically cultivated Swiss chard (Beta vulgaris L. ssp.

Translation of Irrigation, Drainage, and Electrical Conductivity Data in a Soilless Culture System into Plant Growth Information for the Development of an Online Indicator Related to Plant Nutritional Aspects

Agronomy, 2020
Electrical conductivity of the growing media or drainage indicates the nutritional conditions in the cultivation system. However, the nutrient uptake phenomenon has not been related well to the soilless culture system.
