In recent years, increasing the awareness on the environmental problems, especially global warming, has increase the concerns about the impact of emissions on the global climate. The current study was conducted to evaluate and analyze the environmental effects of rapeseed production in the form of life cycle using SimaPro software with the aim concentration on climate changes and impact of acid...

in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...

In 1989, a watershed acidification experiment was begun on the Fernow Experimental Forest in West Virginia, USA. Ammonium sulfate fertilizer (35.5 kg N ha yrand 40.5 kg S ha yr) was applied to a forested watershed (WS3) that supported a 20-year-old stand of eastern deciduous hardwoods. Additions of N and S are approximately twice the ambient deposition of nitrogen and sulfur in the adjacent mat...

Interrelations exist in the terrestrial ecosystems between the plant type and characteristics of nutrient uptake. Annual net nitrogen mineralization in soils of different plant communities in the high altitude zone of Spil mountain located in the Mediterranean phytogeographical region of Turkey was investigated throughout one year by field incubation method. Seasonal fluctuations resulting from...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
