Compost - N recovery : 15 N natural abundance quantitative approach Caio
The remarkable influence of organic inputs, such as manure and compost, on dN values of growing plants suggests the possible use of N natural abundance as a tracer of N. Thus, using N natural abundance might be possible to estimate compost-N recovery as an alternative method to the use of N-enriched materials. The objective of this study was to verify the feasibility of using dN value to esti...

متن کاملThe Nitrogen Paradox in Tropical Forest Ecosystems
Observations of the tropical nitrogen (N) cycle over the past half century indicate that intact tropical forests tend to accumulate and recycle large quantities of N relative to temperate forests, as evidenced by plant and soil N to phosphorus (P) ratios, by P limitation of plant growth in some tropical forests, by an abundance of N-fixing plants, and by sustained export of bioavailable N at th...
متن کاملNitrogen cycling and nitrogen saturation in temperate forest ecosystems.
The last decade has seen a dramatic shift in the focus of nitrogen cycling research in forest ecosystems. Concerns over nitrogen deficiencies and effects of removal in harvest have given way to concerns over excess nitrogen availability and the potential for forest decline and surface water pollution. Driving this paradigm shift is the increase in atmospheric deposition of nitrogen to forests d...
متن کاملRegional patterns of 15N natural abundance in forest ecosystems along a large transect in eastern China
The regional determining factors underlying inter- and intra-site variation of (15)N natural abundance in foliage, O horizon and mineral soil were investigated in eastern China.(15)N natural abundance values for these forest ecosystems were in the middle of the range of values previously found for global forest ecosystems. In contrast to commonly reported global patterns, temperate forest ecosy...
