the interaction between nitrogen levels: 100, 150 and 175 kg ha-1, as ammonium sulfate (ams) and glyphosate: 1) 61.5 gr a.i. ha-1 sprayed in three parts, 30, 40 and 50 dap, 2) 61.5 gr a.i. ha-1 sprayed in two parts, 30 and 50 dap, 3) 86 gr a.i. ha-1 sprayed in three parts as level one, 4) 86 gr a.i. ha-1 sprayed in two parts as level two on broomrape shoot density and dry mater and tomato yield...

Abstract Purpose Nitrification inhibitor plays an important regulatory role in inhibiting the nitrification of ammonium soils. However, most inhibitors lack sustainable effects suppressing ammonium. In this study, a novel DMS was prepared and tested to explore its lasting effect suppression black soil. Materials methods Both culture experiments field trial were performed Three kinds (NIs), dicy...

In this work a set of experiments was undertaken in a pilot-scale WSP system to determine the importance of organic nitrogen sedimentation on ammonium and total nitrogen removals in maturation ponds and its seasonal variation under British weather conditions, from September 2004 to May 2007. The nitrogen content in collected sediment samples varied from 4.17 to 6.78 percent (dry weight) and cal...

in order to investigate the effect of different ratios of ammonium: nitrate on the photosynthesis and fatty acid composition in canola (brassica napus l.) under different levels of salinity, an experiment was conducted as a factorial based on complete randomize design at agricultural research center in east azerbaijan in 2010. the first factor was different ratios of nitrogen sources to ammoniu...

The pyrolytic process in preparing rayon into activated carbon fiber was studied by thermogravimetric analyses (TGA) and differential thermal gravimetry (DTG). For the promotion of the pyrolytic reaction and increment of carbonization yield, impregnants including phosphoric acid (PA) and its three ammonium salts, as well as the ammonium sulfate (AS), are added respectively for best resultant bo...

Low levels of glucoamylase are produced when Aspergillus niger is grown on sorbitol, but substitution of the latter by glucose, maltose, or starch results in greater formation of glucoamylase as measured by enzymatic activity. Both glucoamylase I and glucoamylase II are formed in a yeast extract medium; however, glucoamylase I appears to be the only form produced when ammonium chloride is the n...

Inorganic components were measured in the aged ambient aerosols from Cape Hedo, Okinawa, an outflow region of East Asia, using online quadrupole Aerodyne aerosol mass spectrometer (Q-AMS) and offline ion chromatography (IC) Sunset Lab carbon analyzer. Here, we performed inter-comparison study on nitrate (NO3−), ammonium (NH4+) sulfate (SO42−) that by IC AMS. Sulfate showed a good agreement betw...

Isolation of bacteria able to utilize s-triazines as the sole and limiting nitrogen sources for growth is described. Three strains of Pseudomonas (A, D, and F) and two strains of Klebsiella pneumoniae (90 and 99) were examined. Strains D and F utilized N-ethylammelide, N-isopropylammelide, ammeline, ammelide, cyanuric acid, and ammonium ion as nitrogen sources. Strain A utilized melamine, ammel...

The objective of this paper is to critically review the significance of MBR technology for wastewater treatment derived Biodiesel plant with Alkali-Catalyzed Trans-esterification process. The whole study was carried out into two stages. In the first stage, pretreatment was studied with H2SO4 at the different pH range of 2.4 to 9 along with the removal efficiencies of BOD, COD and Oil & Greases....

Ovotransferrin is one of the major egg white proteins that have antimicrobial activity as well as iron binding capability. The objective of this study was to develop a simple and easy method to separate ovotransferrin without using organic solvents. Egg white was separated from yolk, added in a 1:1 ratio to distilled water (DW), and then homogenized. The ovomucin in the diluted egg white was re...
