Negative response values demonstrate deleterious effects of nitrogenous fertilizers on crop yields if applied without other nutrients or lime.
A second possibility is that nitrogenous compounds facilitate intercellular communication in some way, or are mediators of such communication.
Among the numerous factors and effectors of that process, the role of nitrogenous compounds evolving nitric oxide emerged in recent years.
Excretion of metabolic wastes including nitrogenous compounds, as well as xenobiotics, is critical for survival of the organism.
However, in bucephalids, nitrogenous waste accumulation and glycogen depletion could be equally important factors in the limitation of their free-swimming existence.
Other substances investigated in terrestrial snow and ice include nutrients and organic nitrogenous compounds.
In most cases, nitrogenous compounds enhance light-induced germination, but cannot completely replace the light requirement.
In rural areas, it is possible to heed the call of nature on the land, with the nitrogenous and carbonaceous matter being quickly absorbed into the hungry soil.
