Environmental Nitrogen For Plant Growth

Donald S. Galitz-1972-01-01-NDSU Repository (North Dakota State University)

TL;DRAbstract

The topic is environmental nitrogen to be used for the fertilizing crops. In 1972, with the increased interest in all the ecological aspects of the mobile components of the environment, it was necessary to understand the complete dynamics of elements such as nitrogen. To achieve this one must consider their cycling in terms of all the sources of input into the system, the various points at which there may be losses, and the energy levels at which these inputs and losses occur. The inputs and the withdrawals from the various nitrogenous pools in the environment have been estimated with considerable accuracy by numerous techniques. As a result of research projects, we have a general picture of the major mechanisms by which the different forms of nitrogen are transformed from one to another. The article has an illustration of the nitrogen cyclization cycle. Analyses of nitrate reduction and assimilation have been performed on young seedlings of a number of weeds and crops to indicate thei
