Fertilizers with coated urea in upland rice production and nitrogen apparent recovery

Bioscience Journal, 2016
Urea is the most used N fertilizer for upland rice, however, a great percentage of N loss can occur with the use of this fertilizer. The use of products that provide reduction of N loss for urea fertilizers can contribute to increase N use efficiency ...

The combination of compost or biochar with urea and NBPT can improve nitrogen-use efficiency in maize

Anais da Academia Brasileira de Ciências
The addition of organic residues to agricultural soils has been used as a practical alternative to improve crop quality and health. The objective of this work was to evaluate maize physiological and nutritional responses to the application of compost and

Field efficacy of urease inhibitors for mitigation of ammonia emissions in agricultural field settings: a systematic review

Frontiers in Environmental Science
Globally, ammonia (NH3) is one of the key air pollutants and reducing NH3 emissions and the associated indirect emission of the greenhouse gas nitrous oxide remains challenging for the agricultural sector.

Nitrogen fertilisation efficiency and wheat grain yield affected by nitrogen doses and sources associated with Azospirillum brasilense

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
The nitrogen fertilisation management should focus on increasing fertilisation efficiency in favour of a more sustainable and productive agriculture. Thus, this study aimed to evaluate the effect of inoculation with Azospirillum brasilense, associated to

Does 3,4-dimethylpyrazole phosphate or N-(n-butyl) thiophosphoric triamide reduce nitrous oxide emissions from a rain-fed cropping system?

, 2018
Nitrification and urease inhibitors have been used to reduce nitrous oxide (N2O) emissions and increase nitrogen use efficiency in many agricultural systems. However, their agronomic benefits, such as the improvement of grain yield, is uncertain. A two-

The Unexploited Potential of Nutrient Analysis in Potato Tissues at the Onset of Tuberization for Tuber Yield Prediction

Agronomy, 2020
Nutrient analysis of potato leaves in early growth is not sufficient for a reliable prediction of tuber yield. This hypothesis was verified based on a field experiment conducted during 2006−2008.

Emissions variability of greenhouse gases within and between sites during late‐season corn production in Mississippi

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Variability of greenhouse gas (GHG) fluxes and emissions among replicates in a study area can have an impact on results depending on the statistical tools used to assess significant differences among fixed effects. The objective of this study was to assess the effect of site and time (i.e., date) and the variability within and between sites on

Nitrogen Fertilizer Sources and Application Timing Affects Wheat and Inter-Seeded Red Clover Yields on Claypan Soils

Agronomy, 2014
Controlled-release N fertilizer, such as polymer-coated urea (PCU), may be a fall N management option for wheat (Triticum aestivum L.) grown in poorly-drained claypan soils. Field research evaluated (1) urea release from fall-applied PCU in 2006 and 2007;

Waterlogged corn responded to post‐flooding N in Ohio

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Precipitation patterns in the U.S. Midwest have become more erratic, increasing the occurrence of flooding and soil waterlogging. Current nitrogen (N) management recommendations for corn (Zea mays L.) do not fully consider the effects of excess water or the use of split N applications when determining optimal N rates.
