Nitrate removal from aqueous solution using natural zeolite-supported zero-valent iron nanoparticles
chemical reduction kinetic modelling nanoscale zero-valent iron particles natural zeolite nitrate sorption isotherm
2015/3/10
A report on the synthesis and characterization of nanoscale zero-valent iron in the presence of natural zeolite as a stabilizer is presented. This novel adsorbent (Ze-nZVI) was synthesized by the sodi...
Soil nematode responses to fertilization with ammonium nitrate after six years of unfertilized apple orchard
ecological indices soil food web bioindicator nitrogen fertilizer Malus domestica
2014/10/24
A nematode community was used as a bioindicator of changes in agroecosystems caused by fertilization. The effect of applying nitrogen (N) fertilizer on a soil nematode community structure was studied ...
Cultivar Differences in Dependence on Nitrogen Fixation of Soybeans in the Field with a High Soil Nitrate Level Determinated by the Relative Ureide Abundance Method
Cultivar difference High soil nitrogen Nitrogen fixation Nodule Relative abundance of ureide
2009/7/8
Nitrogen fixation by soybeans is reduced by high soil nitrate levels. This reduced nitrogen fixation capacity increases the dependence on soil nitrogen, which may result in depletion of soil nitrogen...
Control of Nitrate Concentration in Komatsuna (Brassica rapa L. Perviridis Group) Plants in a Greenhouse at High Temperature Seasons in the Andisols Area
leafy vegetable nitrate nitrogen nitrogen mineralization soil diagnosis
2009/7/7
Komatsuna ‘Natsurakuten’ was cultivated during three successive crop seasons (early summer, late summer, autumn) in the same soil consisted of andisols in a greenhouse. Four fertilization formulae wer...
Ultra-fine Coatings on Sediment Grains Influence Nitrate and Sulfate Storage in Soil
Ultra-fine Coatings Sediment Grains Nitrate and Sulfate Storage Soil
2009/12/16
Tiny sediment grains are covered with a very fine-grained, complex mixture of minerals in an open fabric that results in a large surface area in contact with water between the grains. Scientists at th...
Effect of Regional Different N-Fertilizer Applications on Nitrate Accumulation in Winter Vegetables Grown on Tokat Region
Nitrogen fertilizer applications nitrate winter vegetables
2009/1/14
The main object of this study was to observe the effect of regional N-fertilizer applications on the nitrate accumulation of some winter vegetables grown on farmer's fields located at different parts...
Yield and Petiole Nitrate Concentrations of Cotton Treated with Soil-Applied and Foliar-Applied Nitrogen
Foliar-Applied Nitrogen Soil-Applied Cotton Treated
2008/5/13
Nitrogen fertilization and N nutrient management are crucial components of economically successful cotton (Gossypium hirsutum L.) production. The efficacy of foliar N applications and the timing crite...
Redox potential, nitrate content and pH in flooded Eutric Cambisol during nitrate reduction
soil redox potential denitrification pH
2014/2/27
Topsoils from 16 arable Cambisols developed from sand, loam and silt were used to study soil ability to nitrate reduction under flooding conditions. The strongest drop of redox potential (Eh) was obse...
