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 ...

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 ...

NITROGEN FERTILIZERS

open access: yes, 2023
Nitrogenous fertilizers are organic and inorganic substances that contain nitrogen and are used as a source of nitrogen nutrition for plants, a source of nitrogen nutrition for plants. Nitrogen fertilizers were produced in the chemical industry in 1914–18 after the industrialization of the synthesis of ammonia from atmospheric nitrogen and hydrogen.

Nutrition Rather Than Phytohormone-Dependent Defense of Host Plant Mediates the Different Response of Red- and Green-Morph Pea Aphids to Nitrogen Fertilization

open access: yesAgronomy
Nitrogen fertilization is widely known to affect plant metabolism, which subsequently influences phytophagous insects through a bottom-up effect. The interplay between plants and insects is often overlooked in studies examining the effects of nitrogen ...
