Abstract Two experiments were conducted to evaluate the efficacy of an oil-based substrate, The Water Cleanser™ (TWC). first experiment studied effects two substrates different oil composition (TWC, TWC +), and a commercial bacterial additive (Bio-Aid) on concentrations nitrogen phosphorous in indoor aquaria. second TWC, additive, combination (TWC + B) phosphorous, phytoplankton abundance diver...

Over two-thirds of the soils in world suffer from phosphorus shortages (P). Due to being unavailable all but a small portion plants, agricultural productivity diminishes. Phosphorus-deficient have traditionally been fertilized order decrease severity environmental impact. Improving management practices for sustainable crop output, including reduction loss terms runoff, is emphasis this study. I...

Previous studies conducted on the hydrography, chemical and biological characteristics of Lake Edku; one of the northern Nile Delta Lakes, concluded that this lake suffered from a high level of eutrophication, due to the heavy load of nutrients, especially phosphorus. Before deciding what type of treatment should be used for decreasing total phosphorous (TP), knowledge of the sources and sinks ...
