Carbon dioxide level and form of soil nitrogen regulate assimilation of atmospheric ammonia in young trees. [PDF]

open access: yes, 2015
The influence of carbon dioxide (CO2) and soil fertility on the physiological performance of plants has been extensively studied, but their combined effect is notoriously difficult to predict.

The Effects of Nitrogen Fertilization and Deficit Irrigation Practices on Tomato Growth and Chlorophyll Concentration [PDF]

open access: yes, 2018
Irrigation and fertilization are absolutely necessary in order to increase productivity in agricultural production. Water is the most important source of life on the earth. All living things need absolute water so that they can continue plants life.

Nitrogen fertilizer: Retrospect and prospect [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
The rising fertilizer use accompanying more people eating more has been called exponential (1) and prompted fears of polluted water and consequent methemoglobinemia (2) and hypoxia (3). It also has raised alarm about greenhouse warming (4) and an altered global N cycle and thus primary production (5) and diversity (1) of vegetation. In this plethora of

A Knowledge-Based Model for Nitrogen Management in Rice and Wheat

open access: yesPlant Production Science, 2009
Excessive nitrogen fertilization results in low nitrogen-use efficiency. To improve nitrogen management for high yield and high nitrogen efficiency in rice and wheat, we developed a knowledge-based nitrogen fertilization model by integrating the ...

Total and yeast assimilable nitrogen composition in grape juices of three grapevine cultivars as affected by vineyard nitrogen fertilization [PDF]

open access: yesJournal of Central European Agriculture, 2011
Nitrogen fertilization is one of the common agrotechnical practices in vitculture, by which we can achieve higher content of nitrogen compounds in grapes.

Meta-analysis reveals ammonia-oxidizing bacteria respond more strongly to nitrogen addition than ammonia-oxidizing archaea [PDF]

open access: yes, 2016
Shifts in microbial communities driven by anthropogenic nitrogen (N) addition have broad-scale ecological consequences. However, responses of microbial groups to exogenous N supply vary considerably across studies, hindering efforts to predict community ...

Rhizosphere-Associated Microbiomes of Rice (Oryza sativa L.) Under the Effect of Increased Nitrogen Fertilization

open access: yesFrontiers in Microbiology, 2021
Crops assemble and rely on rhizosphere-associated microbiomes for plant nutrition, which is crucial to their productivity. Historically, excessive nitrogen fertilization did not result in continuously increasing yields but rather caused environmental ...

Effect of Nitrogen Fertilization on Savvatiano (Vitis vinifera L.) Grape and Wine Composition

open access: yesBeverages, 2022
Nitrogen nutrition is one of the most effective cultural practices in vineyards. The vine nitrogen status influences the berries’ quality characteristics and the produced wines.
