When eggs are stored beyond 7 d, hatchability and chick quality decrease. The cause of the negative effects of prolonged egg storage is not clear. The negative effects may be caused by a decrease in embryo viability due to an increase in cell death. The optimal time and curve of preincubation warming (the preincubation warming profile) may be different for eggs stored over short and long period...

The application of phosphogypsum (PG) on sodic soils provides nutrients to the soil, reduces toxic effect Na+, and improves soil properties. Laboratory experiments were performed evaluate effects PG chemical properties soils. treatments arranged in a completely randomized design with five replications. included 0% GR (control), 50% (28.18 g·kg−1), 100% (56.37 150% (84.50 200% (112.74 g·kg−1) ra...

Mineralization of carbon (C) is a burning issue that regulated by soil attributes. It has direct impacts on crop productivity and quantification organic residue addition in soil. For better understanding achievement potential tillage benefits, comprehensive scientific C mineralization very important. Therefore, laboratory incubation experiment was conducted to investigate the rates kinetics res...

Abstract The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation polluted soils. In this manuscript we study under laboratory conditions capacity new biostimulant obtained from slaughterhouse sludge in soil by oxyfluorfen at rate 4 l ha −1 (manufacturer’s recommended) over 90-day period. We determined its effects on dehydrogenase, urease, β-...

Soil incubation and pot experiments were conducted to follow the sorption processes of added phosphorus (P) fertiliser using radioisotope tracer technique. Increasing doses P (40, 80, 160, 320 mg P/kg soil) Chernozem Arenosol incubated for 1, 3, 13 weeks. After incubation, perennial ryegrass (Lolium perenne L.) was sown in one group pots, experiment had been continuing another 9 The yield, gras...

Biochar (BC) is a material that has many applications in agricultural and environmental activities. The aim of the study was to define influence BC produced low-temperature pyrolysis from various organic waste materials, including one-month-old compost (OMOC), pine bark (PB), needle mulch (NM), cones (PC) maple leaves (ML), on soil enzyme activity as well its relation with matter properties. A ...
