The properties of soil obtained from the sludge water treatment plants were investigated. A new recipe for obtaining peat, river sand and dehydrated with cotton dust was developed. is well structured, resistant to unfavourable mechanical physical-chemical impacts. It recommended creating lawns, planting sports grounds, squares road slopes. can be used filling landfills solid municipal waste, st...

The incidence of obesity and overweight has reached epidemic levels in the United States and developed countries worldwide. Even more alarming is the increasing prevalence of metabolic diseases in younger children and adolescents. Infants born to obese, overweight, and diabetic mothers (even when normal weight) have increased adiposity and are at increased risk of later metabolic disease. In ad...

Thick smoke routinely cloaks Southern California hills, highways, and neighborhoods during this region’s autumn wildfire season, with drought contributing to worse fires than usual in the past two years. Wildfire emissions generate larger aerosols than those produced by vehicles—up to 0.4 micrometers (μm) in diameter compared with less than 0.15 μm—according to a new study led by Constantinos S...

The soil nourishing the crops that provide our food and fiber is a complex environment where microbes live in numbers estimated to reach 2 billion per ounce of soil. Millions upon millions of individual bacteria and fungi Uve on root surfaces and the soil particles that surround them. Bacteria are the smallest and the most abundant. The fungi, usually larger than bacteria, are found throughout ...

• Since mycorrhizal fungi constitute an important component of the soil–plant interface, their responses to changes in nutrient availability may mediate shifts in ecosystem function. We tested the hypothesis that initial soil nutrient availability may determine effects of nitrogen (N) and phosphorus (P) additions on the growth and community of arbuscular mycorrhizal (AM) fungi. • Extraradical h...

The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had...

Soil sealing has negative impacts on ecosystem services since urban green and soil get lost. Although there is political commitment to stop further sealing, no reversal of this trend can be observed in Europe. This paper raises the questions (1) which strategies can be regarded as being efficient toward ecologically sustainable management of urban soil sealing and (2) who has competences and sh...
