Simulation of inorganic nitrogen dynamics and shrimp survival in an intensive shrimp culture system
(Aquaculture Research, 2002, 2010)
Litter quality of C3 perennial grasses and soil inorganic nitrogen in a semi-arid rangeland of central Argentina
(elsevier, 2008-09)
The study was undertaken to quantify litter quality of six C3 perennial grasses and species effects on soil inorganic nitrogen (N) in a semiarid rangeland of central Argentina. Leaf litter and roots were analyzed for N, ...
Challenging the paradigm of nitrogen cycling: no evidence of in situ resource partitioning by coexisting plant species in grasslands of contrasting fertility
(Wiley, 2015-01)
In monoculture, certain plant species are able to preferentially utilize different nitrogen (N) forms, both inorganic and organic, including amino acids and peptides, thus forming fundamental niches based on the chemical ...
Organic and inorganic P forms in soil as affected by cover crops and nitrogen fertilization
(Empresa Brasil Pesq Agropec, 2016-11-01)
The objective of this work was to evaluate the effects on organic and inorganic forms of soil phosphorus of the cultivation of cover crops and the use of nitrogen levels in soil under notillage system. The experiment was ...
Nitrogen Fertilizer Efficiency Determined by the 15N Dilution Technique in Maize Followed or Not by a Cover Crop in Mediterranean Chile
(MDPI, 2021)
Nitrogen (N) in a maize crop is a determining yield factor, but its negative impact on the environment is also known. Therefore, it is necessary to propose mitigation strategies that allow an improvement in the N fertilizer ...
Cover crops and controlled-release urea decrease nitrogen mobility and improve nitrogen stock in a tropical sandy soil with cotton cultivation
(2022-01-01)
Sandy soil often has low nitrogen (N) stock. Thus, crops grown in sandy soil rely on high levels of N fertilization. The use of cover crops and efficient fertilizers can increase N stock in the soil and N availability in ...
Physiological performances of two populations of Compsopogon caeruleus (Rhodophyta) to inorganic nitrogen and phosphorus impoverishment
(2014)
Studies on the effects of inorganic nutrients manipulation (specially nitrogen and phosphorus) in freshwater macroalgae are scarce. Physiological responses (growth, photosynthesis, and pigment contents) to nitrogen and ...
Effects of fire on soil nitrogen dynamics and microbial biomass in savannas of Central Brazil.
(Pesquisa Agropecuária Brasileira, Brasília, v.38, nº 8, p.955-962, ago. 2003., 2014)
