Impact of Microbial Uptake on the Nutrient Plume around Marine Organic Particles: High-Resolution Numerical Analysis

open access: yesMicroorganisms, 2022
The interactions between marine bacteria and particulate matter play a pivotal role in the biogeochemical cycles of carbon and associated inorganic elements in the oceans.

Simple models and concepts as tools for the study of sustained soil productivity in long-term experiments. II. Crop nutrient equivalents, balanced supplies of available nutrients, and NPK triangles [PDF]

open access: yes, 2011
Two NPK factorial trials, one in Vietnam and one in The Netherlands were (re-)analyzed to find causes of success or failure with regard to sustained soil productivity, using the concept of crop nutrient equivalents (CNE).

Relationships between Nutrient Uptake and Nitrogen Fixation with Aflatoxin Contamination in Peanut under Terminal Drought

open access: yesAgronomy, 2019
Terminal drought greatly enhanced Aspergillus flavus Link infection (AI) and aflatoxin contamination (AC) in peanut. Identification of new surrogate traits which have an association with AC may be effective to improve peanut varieties with reduced AI and

Independent colimitation for carbon dioxide and inorganic phosphorus. [PDF]

open access: yesPLoS ONE, 2011
Simultaneous limitation of plant growth by two or more nutrients is increasingly acknowledged as a common phenomenon in nature, but its cellular mechanisms are far from understood.

Studies on plants that hyperaccumulate copper, cobalt and nickel : their potential for use in phytomining and phytoremediation : a thesis presented in partial fulfillment of the requirements for the degree of Masterate of Science in Soil Science at Massey University [PDF]

open access: yes, 1998
This thesis reviews three lines of research on hyperaccumulators to examine their potential for phytoremediation and phytomining. The first line of research was to test the affect of nutrient addition on biomass and nickel uptake by two nickel ...

Non-growing season plant nutrient uptake controls Arctic tundra vegetation composition under future climate

open access: yesEnvironmental Research Letters, 2021
Plant growth and distribution in high-latitude tundra ecosystems is strongly limited by nutrient availability and is critical for quantifying centennial-scale carbon-climate interactions. However, land model representations of plant–nutrient interactions

Nitrogen uptake and internal recycling in Zostera marina exposed to oyster farming: eelgrass potential as a natural biofilter [PDF]

open access: yes, 2016
Oyster farming in estuaries and coastal lagoons frequently overlaps with the distribution of seagrass meadows, yet there are few studies on how this aquaculture practice affects seagrass physiology.

NUTRIENT UPTAKE OF SWEETPOTATO CULTIVARS [PDF]

open access: yesHortScience, 1991
The uptake of nutrients by sweetpotato (Ipomoea batatas) is critical in determining crop yield. Research was conducted to assess the effects of gypsum application on the nutrient uptake in three sweetpotato cultivars; `Carver II', `Georgia Jet' and `Jewel'. Gypsum application did not influence leaf P content of sweetpotato.

Responses of ectomycorrhizal fungi to mineral substrates [PDF]

open access: yes, 2003
Boreal forest soils are complex, heterogeneous growth substrates where organic and mineral components provide nutrient resources for soil organisms and plants. Mineral nutrients are cycled between living and dead organic components of the forest soil and

Nitrogen phytoremediation by water hyacinth (Eichhornia crassipes (Mart.) Solms) [PDF]

open access: yes, 2008
The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm.
