Nitrogen (N) is an essential element for the growth of organisms and the productivity of forest ecosystems .In headwater catchments, soil N mineralization of organic matter plays an important role in determining soil N availability, primary productivity and N losses from soil to stream, thus contributing to ground water contamination and the pollution of the water environment [1,2,3,4].Cited by: 1. A series of laboratory experiments were conducted to establish the relationship between nitrogen (N) isotope composition of cattle manure and ammonia emissions, potential contribution of nitrogenous gases other than ammonia to manure N volatilization losses, and to determine the relative contribution of urinary- vs. fecal-N to ammonia emissions during the initial stage of manure by:

Samples were then analyzed for N concentration using a combustion O, N, and H elemental analyzer (ONH, LECO Corp.) by the University of Tennessee Soil, Plant, and Pest Center, Nashville, TN. A cell, by m frequency grid (Vogel and Masters, ) was used to estimate legume stand densities in early summer.
Studies of population exposure have demonstrated increased incidences of acute respiratory ill- ness in young children associated with combustion products from gas stoves of which N02 is a significant component, but the exact effective concentra- tions and exposure times are difficult to determine.

Nitrogen isotopic studies in Azolla were carried out to develop improved fertilizer N practices in rice-based cropping systems. Over the past two decades CRPs have focussed on the development of 15 N methodology for measuring and enhancing biological N fixation, especially in N 2 -fixing legume : F.
Zapata, C. Hera. This new edition of a well-established book introduces the basic soil science theory which is essential for the proper use and maintenance of this resource. It places greater emphasis on sustainable production and environmental protection, and incorporates the new soil classification system.
The text covers all essential areas: pedology, soil chemistry and fertility, soil physics, and land use.

In direct sowing, desiccation of the cover crops with herbicides can affect N availability in agroecosystems, reducing N use efficiency by the crop in succession. In this sense, the objective of the study was to evaluate nitrogen losses in the soil-plant system after application of the herbicides glyphosate and glufosinate-ammonium on pearl millet [Pennisetum glaucum (L.)
