Ammonia volatilization losses from urea coated with copper, boron, and selenium

open access: yesSemina: Ciências Agrárias, 2020
Urea coated with copper and boron may be a vehicle for selenium fertilization in grazing systems to improve both forage and animal productivity, and consequently, the nutritional quality of milk and meat.

Ammonia volatilization from manure mixed with biochar [PDF]

open access: yesCanadian Journal of Soil Science, 2022
Ammonia (NH3) volatilization from NH3-based fertilizer and animal manure reduces their nitrogen (N) fertilizer value and is a source of environmental pollution. Mixing manure with biochar may lower NH3 volatilization from manure by adding H+, adsorbing mineral N, or increasing N immobilization in microbial biomass.

Reducing Ammonia Volatilization from Urea Fertilizer Applied in a Waterlogged Tropical Acid Soil via Mixture of Rice Straw and Rice Husk Biochars

open access: yesJournal of Agricultural Sciences, 2022
Nitrogen deficiency frequently occurs in agricultural soil because of ammonia volatilization to the environment, resulting in low urea-N use efficiency by plants.

A methodology for estimating the ammonia emission from crop residues at a national scale

open access: yesAtmospheric Environment: X, 2019
Crops and crop residues contribute to pollution of the environment by ammonia (NH3) volatilization. This study focusses on the volatilization from crop residues, defined as residues after a management action or frost i.e.
