There is increasing interest in source separation and treatment of urine so as to recover nitrogen and phosphate more efficiently than treating combined wastewater. Although previous studies primarily focused on struvite precipitation for the recovery of phosphorus, the composition of urine changes during storage. The present study compared the precipitation conditions for fresh urine and hydro...

The experiment was conducted at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya during 2018-19 to study the nutrient uptake (NPK), use efficiency and grain yield of rice (Oryza sativa L.) in different establishment methods under varied management practices. laid out a split plot design with three replications. main comprised viz., semi dry rice, drum seeded transplanted w...

In this study, the nitrogen fixing bacteria VIT SS 1-6 were screened from the root nodules of Groundnut (Family: Fabaceae, Species: Arachis hypogaea) collected from Vellore district were examined for their plant growth promoting properties. Of the six isolates obtained, five were fast growing and one was slow growing. The slow growing species VIT SS5 was further examined for its nitrogen fixing...

Constructed and natural wetlands are being used extensively to treat different types of wastewater including the domestic one. Considerable removal efficiency has been achieved for a variety of pollutants like BOD, nitrogen and phosphorous in the wetlands. Wetland treatment appears to be the best choice for treatment or pre-treatment of wastewater because of the low maintenance cost and simplic...

improving the resource use efficiency in agro- ecosystems is an importantfactor for reducing environmental pollution. to evaluate phosphorus (p) efficiency andbalance indicators, research was conducted in wheat and saffron production systems inthe qaenat region (south khorasan province, iran) during 2011 and 2012, based on themethod of the organization for economic co-operation and development ...

Large-area substitutional phosphorus-nitrogen co-doped monolayer graphene is directly synthesized on a Cu surface by chemical vapor deposition using molecules of phosphonitrilic chloride trimer as the phosphorus and nitrogen sources. The doping levels of both phosphorus and nitrogen atoms decrease as a function of the growth temperature. In contrast, the doping effect is enhanced with temperatu...

background: qual2k is a stream water quality model and was used to evaluate the water quality of the kine-vars river and assess the response of the river to nutrient management strategies. methods: for that purpose, 7 sample stations were selected and surface water samples were collected in the winter and summer of 2012 and were analyzed for temperature, dissolved oxygen, biological oxygen dema...

Bacteria able to use at least one of 13 ionic alkylphosphonates of O-alkyl or O,O-dialkyl alkylphosphonates as phosphorus sources were isolated from sewage and soil. Four of these isolates used 2-aminoethylphosphonic acid (AEP) as a sole carbon, nitrogen, and phosphorus source. None of the other phosphonates served as a carbon source for the organisms. One isolate, identified as Pseudomonas put...

in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...

Plants need abundant nitrogen and phosphorus for higher yield. Improving plant genetics for higher nitrogen and phosphorus use efficiency would save potentially billions of dollars annually on fertilizers and reduce global environmental pollution. This will require knowledge of molecular regulators for maintaining homeostasis of these nutrients in plants. Previously, we reported that the NITROG...
