The knowledge about the interaction between mechanical pruning and soil organic amending is still scarce. This study aimed to examine effects of these two practices on wine quality. Syrah grapes from trial fields in Portugal subjected different systems (mechanical pruning; hand spur pruning) five amendment treatments (control, biochar, municipal solid waste compost, cattle manure, sewage sludge...

application of sewage sludge as a cheap and waste material is increasing for supporting plant essential elements especially in the soils of arid and semiarid regions. in the present greenhouse research, the effect of ardabil municipal sewage sludge on n, p, k, pb, cr, ni and cd concentrations in soil and plant and also spring wheat yield and growth indices was studied as a randomized complete b...

The concentrations of some widely used pharmaceuticals, namely fluoroquinolones (ciprofloxacin C H FN O , norfloxacin C H FN O and ofloxacin C H FN O ) and sulfonamides (sulfadimethoxine C H N O S 17 18 3 3 16 18 3 3 18 20 3 4 12 14 4 4 and sulfamethoxazole C H N O S ) were determined in urban sewage sludge utilized for making compost. The 10 11 3 3 levels of degradation of these pharmaceutical...

This paper reviews the sources, bioavailability and fate of heavy metals and organic contaminants in compost manure and in soils of which the manure is applied. The toxicity of heavy metals and organic compounds in soil of which would have come from applied compost is also discussed. Type of materials, their background and where collected for use in composting contribute to the sources of heavy...

A study was conducted to investigate the levels of plant nutrients, heavy metals, parasites and fecal coliform bacteria in Bangkok-produced sewage sludge and finished compost products for potential agricultural application, as well as to compare the quality of compost under different composting conditions. The results indicated that digested sewage sludge had high fertilizing values for organic...

The present study tries to investigate the effect of composting process on some properties and heavy metals status of two municipal sewage sludge (MSS) as affected by three different organic bulking agents (BAs) at three levels (10%, 25%, and 45% V/V). According to the results, the composting process could reduce the fecal coliform to class A, a reduction more obvious in treatments with BAs tha...

to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...
