Delaying application and injecting nitrogen fertilizer with urease and nitrification inhibitors decreased nitrous oxide emissions and enhanced corn yields

Journal of Environmental Quality, EarlyView.
Abstract Early season nitrous oxide (N2O) emissions following nitrogen fertilizer application can be significant if spring rains lead to anaerobic conditions before the crop is established and able to utilize the applied N. However, delaying fertilizer application by 4‐5 weeks after planting usually results in warmer temperatures which promote ammonia (

Phosphorus fractions status of representative agricultural fields in North Carolina

Journal of Environmental Quality, EarlyView.
Abstract Most agricultural soils in North Carolina have high levels of available phosphorus (P), yet little is known about other accumulated P fractions and their associated environmental risks. This study characterized soil P fractions through sequential chemical fractionation of 391 samples (0–10 cm and 10–20 cm) collected from 57 counties across ...

A comprehensive review on the sources, environmental behavior, and degradation of alkylphenol ethoxylates and their metabolites in surface water and soils

Journal of Environmental Quality, EarlyView.
Abstract Alkylphenol ethoxylates (APEOs) and their metabolites, widely used in agricultural, industrial, and household products, are known endocrine disruptors. Since the 1980s, many countries have implemented restrictions on their production and use, necessitating an evaluation of these regulations by reviewing their source and environmental behavior ...
