29 Swine slurry (SS) is usually stored in open ponds in Mediterranean conditions before 30 being applied to crop fields. During this storage nitrogen (N) is lost to the atmosphere 31 mainly by ammonia volatilization diminishing the fertilizer value of the slurry and 32 causing environmental problems. Permeable covers made from plant materials are low33 cost alternatives to reduce these losses. ...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Determining nitrogen fractions in swine slurry.

Nutrient management plans are used to reduce non-point source pollution from animal operations. These plans require manure analysis and use indices to determine nutrient availability. This study evaluated a modified method for determining nitrogen fractions in swine slurry stored under slatted floors, calculating plant available nitrogen, and characterizing nitrogen fractions by holding pit dep...
