Transformations of nitrogen fertilizers in soil

, 1985
The effects of 15N-labelled urea, (NH4)2SO4 and KNO3 on immobilization, mineralization, nitrification and ammonium fixation were examined under aerobic conditions in an acid tropical soil (pH 4.0) and in a neutral temperate soil (pH 6.8). Urea, (NH4)2SO4

Fluctuations of nitrogen levels in soil profile under conditions of a long-term fertilization experiment

Plant, Soil and Environment, 2008
The present study is focused on the correlation between varied long-term fertilization and changes in soil nitrogen concentrations. It was found that all fertilization systems significantly increased the levels of total, mineral and organic nitrogen in ...

NITROGEN FERTILIZERS

, 2023
Nitrogenous fertilizers are organic and inorganic substances that contain nitrogen and are used as a source of nitrogen nutrition for plants, a source of nitrogen nutrition for plants. Nitrogen fertilizers were produced in the chemical industry in 1914–18 after the industrialization of the synthesis of ammonia from atmospheric nitrogen and hydrogen.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...
