Effects of Cross-slope Tillage and Increasing Organic Fertilizer on Soil Nitrogen and Phosphorus Loss Characteristics and Soil Fertility on Gentle Slope

open access: yesShuitu baochi tongbao, 2023
[Objective] Nitrogen and phosphorus loss characteristics and soil fertility changes on a gentle slope of cultivated land were analyzed under optimal fertilization and cross-slope tillage in order to provide a basis for reducing nitrogen and phosphorus ...

Effects of Nitrogen Fertilization on Monoterpenes of Jack Pine Seedlings and Weight Gain of Jack Pine Budworm (Lepidoptera: Tortricidae) [PDF]

open access: yes, 2017
Nine-month old jack pine (Pinus banksiana) seedlings were grown in a greenhouse under four nitrogen fertilization regimes. Levels of total nitrogen and five monoterpenes in new foliage were measured. Fertilization resulted in four significantly different

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 ...
