Accompanying ions of ammonium sources and nitrate : ammonium ratios in tomato plants
(2018-06-01)
The tomato (Solanum lycopersicum L.) cultivar Micro-Tom (MT) is widely used in physiological studies, but the effects of nitrate (NO3 -) and ammonium (NH4 +) ratios (NO3 - : NH4 + ratios) and, in particular, the effects ...
Acute sensitivity to Nitokra sp benthic copepod to potassium dichromate and ammonia chloride
(2012)
The present study assesses acute toxicity of non-ionized ammonia and potassium dichromate using the estuarine benthic copepod Nitokra sp from laboratory cultures. Bioassays with non-ionized ammonia sensitivity were carried ...
Biodegradation of p-Chloroaniline and Ammonium Removal in Continuous Biofilm Reactors
(Wiley VCH Verlag, 2014-04)
In this investigation, we isolated from an industrial effluent a bacterial community capable of utilizing p-chloroaniline (PCA) as the sole source of carbon and nitrogen. The isolates were identified as Pseudomonas sp., ...

Preparation and characterization of spherical yttrium iron garnet via coprecipitation
(2001-12-01)
The purpose of this work is to obtain spherical particles yttrium iron garnet (YIG) by coprecipitation technique. The spherical particles were obtained from either nitrate or chloride salt solutions by controlling the ...
Changes in ec, ph and in the concentrations of nitrate, ammonium, sodium and chlorine in the drainage solution of a crop of roses on substrates with drainage recycling
(Universidad Nacional de Colombia, Facultad de Agronomía, Centro Editorial, 2012)
The rose cultivation system has been changing from soil to substrate on the Plateau of Bogota. The objective of this study was the monitoring of the EC, pH, and the levels of nitrate, ammonium, sodium and chlorine in a ...
