Effect of Sewage Sludge Compost Application on Ammonium- Nitrogen and Nitrate-Nitrogen Contents of an Olive Grove Soil
ثبت نشده
چکیده
The objective of this work was to study the effect of sewage sludge compost on ammonia and nitrate accumulation in the olive-grove soil. This study has been conducted since 1998. To evaluate sewage sludge compost on soil-grove four treatments were set up in a clay loam soil in Seseña (Toledo, Spain). Every experiment was replicated four times. The applied treatments were sewage sludge compost (SSC), sewage sludge compost plus urea (SSC+U), urea (U) and a control (C). Two treatments have provided more N-NH4 and N-NO3 content: U and SSC+U. Thus, results suggest that sewage sludge compost is a fertilizer of slow mineralization for olive grove soil.

Saline soil was amended with 13.3 and 26.6 g kg of Municipal Solid Waste (MSW) compost or sewage sludge, and arylsulphatase (ARY), phosphatase (PHO), dehydrogenase (DEH), β-glucosidase (β-GLU), urease (URE) and catalase (CAT) activities as well as physical-chemical properties were determined after 70 day of incubation under laboratory conditions. MSW compost and sewage sludge significantly impr...

Compost and sewage sludge contain high concentration of plant nutrients and, thus, have been used extensively as an inexpensive fertilizer. The objective of this study was to evaluate cumulative and residual effects of compost, sewage sludge and cow manure on nitrogen, phosphorus and potassium in soil and wheat. The experiment included compost, sewage sludge and cow manure, each applied at 3 ra...

متن کاملNitrogen fixation (acetylene reduction) in a salt marsh amended with sewage sludge and organic carbon and nitrogen compounds.
Seasonal distribution of nitrogen fixation by Spartina alterniflora epiphytes and in surface and soil samples was investigated in a Georgia salt marsh which was amended with sewage sludge or with glucose and/or ammonium nitrate. There was no significant difference between the rates of fixation in the unamended and sewage sludge plots. Additional perturbation experiments suggested that nitrogen ...

Improvement of plant nutrition is one of the approaches for augmenting the drought stress tolerance in plants. Due to low organic-matter content in most soils in arid and semi-arid regions of Iran, application of organic-wastes’ compost can increase water-holding capacity of the soil and improve plant nutrition. So, in this study, the interactive effects of soil moisture and municipal sewage-sl...
