Urea is the most used fertilizer nitrogen (N), and is often applied as urea ammonium nitrate (UAN), which may be an ammonia (NH3) emission source after application.

Abstract Potassium (K) management is key to maximizing corn (Zea mays L.) yield potential. We evaluated the effects of K fertilization timing on tissue‐K concentration, grain yield, and yield components (i.e., number of kernel rows per ear, kernels per row, and 1000‐seed weight).

Differing effects of increasing calcium ammonium nitrate, urea and urea + NBPT fertiliser rates on nitrous oxide emission factors at six temperate grassland sites in Ireland [PDF]
peer-reviewedThe present study evaluated the impact of three nitrogen (N) fertiliser formulations, applied at five N rates, on nitrous oxide (N2O) fluxes and annual direct N2O-N emission factors (EF) in temperate grassland.

Corn response to dicyandiamide and urea fertilizer technology in poorly drained claypan soils
Abstract Nitrogen (N) is a macronutrient that many producers struggle to manage efficiently due to various loss mechanisms. It is challenging to manage optimum N use in poorly drained claypan soils, which are more prone to saturated conditions and gaseous N loss.

Short term physiological implications of NBPT application on the N metabolism of Pisum sativum and Spinacea oleracea [PDF]
The application of urease inhibitors in conjunction with urea fertilizers as a means of reducing N loss due to ammonia volatilization requires an in-depth study of the physiological effects of these inhibitors on plants.

Abstract Enhanced‑efficiency nitrogen (N) fertilizers (EENFs) are designed to improve N use efficiency and minimize losses. Their performance depends on soil properties and the behavior of coating and inhibitor chemistries. We evaluated surface application of 11 EENFs, two conventional fertilizers (Urea, urea ammonium nitrate [UAN]), deep placement of ...

Effect of Natural Based Bio-inhibitors and N (n-butyl) Thiophosphoric Triamide (NBPT) for Slow Release Fertilizer (SRF) Application [PDF]
The application of N (n-butyl) Thiophosphoric Triamide (NBPT) as urease inhibitor with urea fertiliser have shown presence of chlorosis and necrosis on plant leaves that decreases the amount of chlorophyll pigments essential for photosynthesis reaction ...

Liming and enhanced-efficiency nitrogen fertilizers: Ammonia volatilization losses from subtropical no-till [PDF]
In tropical and subtropical agricultural no-till (NT), lime and nitrogen (N) fertilizers are surface-applied. The pH increase from liming can enhance ammonia (NH3) volatilization.

Dynamics of ammonia volatilization from NBPT-treated urea in tropical acid soils
ABSTRACT The urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) reduces NH3 losses from urea (UR) surface-applied to soils, but its efficacy may be lower in acidic soils. The period when urease inhibition occurs efficaciously may change with soil pH. This needs to be clarified in tropical soils which are commonly acidic.

ABSTRACT Lime application to acidic soils is a common practice in agriculture to increase the soil pH and thereby improve soil nutrient availability. Urease inhibitors such as N‐(n‐butyl) thiophosphoric triamide (NBPT) are widely used to reduce ammonia (NH3) losses from urea.
