Water and nitrogen supply effects on four desert shrubs with potential use for rehabilitation activities
(Springer, 2018-07)
Desert evergreen shrubs, which are adapted to low-fertility ecosystems, generally exhibit limited responses to increased nutrient availability and tend to absorb and store nutrients rather than synthesize new tissues. The ...
Effect of source/sink ratio on leaf and fruit traits of blueberry fruiting canes in the field
(ELSEVIER SCIENCE BV, 2018)
Successional changes in soil nitrogen availability, non-symbiotic nitrogen fixation and carbon/nitrogen ratios in southern chilean forest ecosystems
(Springer, 2004)
Vast areas of southern Chile are now covered by second-growth forests because of fire and logging. To study successional patterns after moderate-intensity, anthropogenic fire disturbance, we assessed differences in soil ...
Effects of Nitrogen on Productivity, Grain Quality, and Optimal Nitrogen Rates in Winter Wheat cv. Kumpa-INIA in Andisols of Southern Chile
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Nutritional stress by means of high C:N ratios in the diet and starvation affects nitrogen isotope ratios and trophic fractionation of omnivorous copepods
(Springer, 2019-07)
Nutritional stress, from feeding on low-quality diets or starvation, may cause changes in consumers’ nitrogen isotope ratios (δ15N = 15N/14N) and trophic fractionation (∆15N = δ15Nconsumer − δ15Nfood source), however, ...
Mobility of Nitrogen in the Soil Due to the Use of Organomineral Fertilizers with Different Concentrations of Phosphorus
(Taylor & Francis Inc, 2019-12-20)
The inorganic nitrogen mobility as a response to the use of organomineral fertilizers in interaction with the phosphorus is altered around the granules in variable charge soils. The aim of this research was to evaluate the ...
Variations in Growth and Toxicity in Gymnodinium Catenatum Graham from the Gulf of California Under Different Ratios of Nitrogen and Phosphorus
(Ciencias Marinas, 2012-01-01)
A strain of Gymnodinium catenatum Graham (GCCV-7), isolated from the Gulf of California, was submitted to conditions with different nitrogen-to-phosphorus ratios (5.4, 9.2, 23.5, 44.7, and 74.3) to determine the effect of ...
Impact of point source pollution on nitrogen isotope signatures (delta N-15) of vegetation in SE Brazil
(Springer-verlagNew YorkEUA, 2002)
Effect of nitrogen flow ratio on microstructure, mechanical and tribological properties of TiWSiN x thin film deposited by magnetron co-sputtering
(Applied Surface ScienceBogota , Colombia, 2018-10-31)
We investigate the deposition of TiWSiNx thin films by means of the method of reactive magnetron co-sputtering, setting the nitrogen flow ratios N2/(Ar + N2) at 4.8%, 9.1%,16.7 and 33.3%. The crystallographic structure of ...
