Variations in eco-enzymatic stoichiometric and microbial characteristics in paddy soil as affected by long-term integrated organic-inorganic fertilization
To investigate the effects of different nutrient management regimes on the soil chemical, eco-enzymatic stoichiometric and microbial characteristics, soil samples were collected from a 30-year, long-term field experiment with six plots growing rice. The results showed that as integrated fertilization increased, so did the concentrations of soil total or available nutrients and microbial biomass...
متن کاملSoil-nutrient availability affected by different biomass-ash applications
This study, through an incubation experiment, evaluates the effect that different biomass ashes exert on the extractability of nutrients and some chemical parameters and dehydrogenase activity of a slightly acid soil. Three types of as were selected: two new ashes generated by the dry combustion of olive cake or by gasification of greenhouse vegetable wastes, and a third produced by wood combus...

متن کاملsoil characteristics affected by long term application of sewage wastewater
the long term effects of sewage water irrigation on soil properties and heavy metal concentrations at rohtak city, haryana (india) was investigated. at each location, soil samples were collected from the upper layer (0-10cm) for determination of various physico-chemical parameters. heavy metals (pb, cu, mn, zn, cd, ni, and fe) were also determined. the chemical analysis of sewage effluent showe...
متن کاملSoil carbon and nitrogen sequestration as affected by long-term tillage, cropping systems, and nitrogen fertilizer sources
Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...
