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 ...
Nitrogen source contribution in sugarcane-inoculated plants with diazotrophic bacterias under urea-N fertigation management
(Springer, 2019-06-01)
Although Brazilian sugarcane crops use lower nitrogen rates when compared to other producing countries, the biological nitrogen fixation (BFN) could be performed aiming to reduce costs, since almost all nitrogen fertilization ...
Nitrogen Application in Irrigated Rice Grown in Mediterranean Conditions: Effects on Grain Yield, Dry Matter Production, Nitrogen Uptake, and Nitrogen Use Efficiency
(TAYLOR & FRANCIS INC, 2009)
Field experiments were conducted in the major rice growing area of Chile to evaluate the effects of nitrogen (N) fertilization and site on grain yield and some yield components, dry matter production, N uptake, and N use ...
Nitrogen budget in integrated aquaculture systems with Nile tilapia and Amazon River prawn
(2017-10-01)
The present work aims to describe the nitrogen (N) budget in integrated aquaculture systems with Nile tilapia (Oreochromis niloticus) and Amazon River prawn (Macrobrachium amazonicum) in earthen ponds, with and without the ...
Yield, chemical composition, and efficiency of use of nitrogen by Marandu grass
(Revista Brasileira de Zootecnia, 2017)
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
(Taylor, 2017-05)
Wheat plants were cultivated in pots with the objective of evaluating the effect of two sulfur (S) rates (+S and −S) on (i) shoot growth, S and nitrogen (N) uptake and nitrogen use efficiency (NUE) and (ii) root growth and ...
Photo-Fenton approach for the determination of organic nitrogen in rainwater
(2018-10-01)
The importance of taking the organic forms of nitrogen (ON) into account when estimating atmospheric nitrogen deposition has been known for a long time. However, there is still only a modest amount of data on organic ...
Contribuition of nitrogen from biological nitrogen fixation, nitrogen fertilizer and soil nitrogen on the growth of the common bean and cowpea
(INST AGRONOMICO, 2011)
Biological nitrogen fixation (BNF) constitutes a valuable source of this nutrient for the common bean Phaseolus vulgaris L and cowpea Vigna unguiculata (L.) Walp., being its avaibility affected by mineral N in the soil ...
Nitrogen mineralization in a coarse soil of the semi-arid Pampas of Argentina
(Taylor & Francis, 2012-01)
Use of the nitrogen balance sheet method as a fertilization strategy in the semiarid Pampas of Argentina is restricted because of a lack of available information regarding nitrogen mineralization in its coarse soils. Our ...
