in order to investigate the effects of polyethylene and organic mulches in different irrigation intervals on morphological characteristics and seed grain of sunflower (helianthus annus l.) hybrid azrgol, an experiment was conducted in split-plot design based on randomized complete blocks with three replications at research farm of college of aboureihan, university of tehran during year of 2009....

The intentional use of the vegetative growth of mushroom-forming fungi on wood mulch substrates as a biologically active filtration media, a process known as mycofiltration, is a promising new technology for enhancing biofiltration of stormwater, graywater, and agricultural runoff. Recent trials have documented that Escherichia coli can be selectively removed from contaminated water approximate...

Three palm species common to southern California landscapes were grown and established under mulch treatments. Turfgrass clippings and Eucalyptus sideroxylon mulches increased the growth of king and queen palms and increased survival of king palms. Although palms growing under fresh eucalyptus mulches did not display nutrient de®ciency symptoms, Mexican fan palm and queen palm were not signi®ca...

Potato (Solanum tuberosum L.) ‘Spunta’ plants were grown with the root zone covered by different types of polyethylene plastic mulches. The plastic mulches used were transparent, white, co-extruded black and white, and black. As a control, plants were grown without plastic mulch. The parameters analyzed were soil temperature, root concentration of K and Ca, and enzymatic activities of ATPase an...

This study was conducted to estimate the yield, and identify quantify primary secondary metabolites in fruit of Malus domestica Borkh. cv. ‘Sampion’ under two agrotechnical factors: floor management (herbicide fallow living mulch) dose nitrogen (50, 80, 110, 140 kg ha−1). Compared herbicide fallow, mulch did not decrease yield. Research showed a rich composition phenolic volatile organic compou...

Agricultural plastics area significant contributor to solid waste disposal problems, particularly in areas with heavy use of plastic-covered greenhouses or mulch films. Fieldburning and landfilling are no longer viable options for disposal in many areas. Reuse and reduced weight of films are two methods to reduce the amount of material requiring disposal. Recycling, incineration, and on-site de...

One of the principal components of the contaminant load in urban stormwater runoff is oil and grease (O&G) pollution, resulting from vehicle emissions. A mulch layer was used as a contaminant trap to remove O&G (dissolved and particulate-associated naphthalene, dissolved toluene, and dissolved motor oil hydrocarbons) from a synthetic runoff during a bench-scale infiltration study. Approximately...

Improving water use efficiency and soil properties are two major factors for sustainable development in desert areas. Therefore, this research aims to study the effectiveness of a biological hydrogel, plant vegetation layer, sand and barley straw with rain harvesting techniques through micro-catchment operation on some soil properties including pH, Nitrogen, Electrical conductivity, Sodium Abso...
