Phosphorous is going to be plant nutrient that will limit the agricultural production in the next millennium. It is a major growth-limiting nutrient, and unlike the case of nitrogen, there is no large atmospheric source that can be made biologically available (Ezawa et al., 2002). As regards the role of P, it stimulate root development and growth, gives plant rapid and vigorous start leading to...

This study evaluates the performance of a simple sequencing batch reactor (SBR) with conical geometric configuration in terms aerobic granulation and simultaneous removal COD, nitrogen, phosphorous from synthetic wastewater. The was operated for 328 days 3 different phases. Stable granules measuring around 0.9±0.3 mm good settling properties were formed phase III operation. Optimum removals COD...

Development of cost-effective amendments for treating dairy slurry has become a critical problem as the number of cows on farms continues to grow and the acreage available for manure spreading continues to shrink. To determine effectiveness and optimal rates of addition of either alum or zeolite to dairy slurry, we measured ammonia emissions and resulting chemical changes in the slurry in respo...

The physicochemical characteristics of Libyan Eucalyptus honey were measured including: moisture with 18.00%, sugars (fructose; 40.00, glucose; 32.00%, sucrose; 1.50% & maltose; 4.70%), total proteins; 0.08%, total amino acids; 0.11%, total acidity; 25.00meq./gk, HMF; 4.60mg/kg, color; light amber, ash; 0.17%, total soluble solids; 82.00% and insoluble solids; 0.07%, and electrical conductivity...

We quantified dry and wet deposition of dust, nitrogen, and phosphorus over the southwest Mediterranean region (Sierra Nevada, Spain) and assessed its effects on the nutrient status and the chlorophyll a (Chl a) concentration in two high mountain lakes. Atmospheric deposition of particulate matter (PM) and total phosphorus (TP) were mainly associated with dryfall and showed a seasonal pattern s...
