Productivity and forage quality of a phytodiverse semi-natural grassland under various management regimes [PDF]

open access: yes, 2011
Grassland management experiment (GrassMan) was set up in 2008 on a permanent semi-natural grassland in the Solling uplands, Germany. The main research focus is on the ecosystem functioning of the phytodiverse grassland (e.g.

Seasonal modulation of mesoscale processes alters nutrient availability and plankton communities in the Red Sea [PDF]

open access: yes, 2019
Hydrographic and atmospheric forcing set fundamental constraints on the biogeochemistry of aquatic ecosystems and manifest in the patterns of nutrient availability and recycling, species composition of communities, trophic dynamics, and ecosystem ...

Inflating bacterial cells by increased protein synthesis. [PDF]

open access: yes, 2015
Understanding how the homeostasis of cellular size and composition is accomplished by different organisms is an outstanding challenge in biology. For exponentially growing Escherichia coli cells, it is long known that the size of cells exhibits a strong ...

Uptake of nutrients by lettuce on NFT with controlled composition of the nutrient solution.

open access: yesNetherlands Journal of Agricultural Science, 1991
An automatically-controlled recirculating NFT system was developed, consisting of a growth unit and a measuring and control unit. It is described together with some basic growth and uptake models. Results are presented of a preliminary experiment with the lettuce cultivar Sitonia (using manual control and nutrient dosage).

Nutrient Composition Analysis for Recipes

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: Having an accurate nutrition profile for recipes is crucial for various applications, such as dietary analytics, recommendation systems, and nutritional assistance. However, online databases often collect recipes from various sources to increase the variety and quantity of the dataset.

Nutrient solutions for Arabidopsis thaliana: a study on nutrient solution composition in hydroponics systems [PDF]

open access: yesPlant Methods, 2020
Abstract Background There is little information on the effect of nutrient solutions composition on Arabidopsis growth. Therefore, we compared growth performance of Arabidopsis thaliana (Col-0) grown on the most commonly used nutrient solutions in deep water culture: Hoagland and Arnon, Murashige and Skoog, Tocquin, Hermans, and Conn.

Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]

open access: yes, 2009
Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...

Data for life cycle assessment of legume biorefining for alcohol [PDF]

open access: yes, 2019
Benchmarking the environmental sustainability of alcohol produced from legume starch against alcohol produced from cereal grains requires considering of crop production, nutrient cycling and use of protein-rich co-products via life cycle assessment. This

Variability in wheat: factors affecting its nutritional value [PDF]

open access: yes, 2008
Wheat is a common raw material used to provide energy in broiler diets. Its apparent metabolisable energy and its influence on broiler performance varies between wheat samples.
