A person should take about 90–100 g of protein day, largely from animal sources, despite the growing need for vegetable protein. Animal feed with insufficient causes them to consume excessive amounts fodder, increasing their plant The production must significantly expand in order fulfill demands husbandry. demand is on rise, and it recommended that an individual approximately 90-100 per primari...

Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...

The concentrations of potentially toxic elements (PTEs) in the topsoils Udachny mining area were determined. soil samples taken from 42 topsoil at a depth 0-20 cm. PTEs (Pb, Cd, Cr, Zn) analyzed by atomic absorption method on MGA-1000. In addition, pH and organic matter (humus) measured for each sample. potential ecological risk was quantitatively estimated site. most severe contamination study...

Goal. To develop a comparative correlation model of the interconnections ecological-trophic groups soil microorganisms with agrophysical, physicochemical indicators, humus condition, productivity degraded chernozem and to determine energy efficiency use intensive, low-intensive, organic fertilizer systems using by-products crops as fertilizers in 5-field grain-spray crop rotation for conditions...

Vermiculture is the culture of earthworms. The goal is to continually increase the number of worms in order to obtain a sustainable harvest. The worms are either used to expand a vermicomposting operation or sold to customers who use them for the same or other purposes. Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like materia...

Urbanozems with typical pollution are formed along railways: heavy metals (HM), oil products, anthropogenic organic matter. Depending on the natural zone and intensity of leaching regime, accumulated can have a different effect integral environmental indicators soils – toxicity enzymatic activity. The aim work was to determine influence railway physicochemical characteristics adjacent urbanozem...
