2014/10/28
The area devoted to growing tobacco (Nicotiana tabacum L.) in the province of Granma, Cuba, accounted for nearly 2600 ha in the year 1997, which represented the 4% of the total tobacco plantation area...
Relative effects of anaerobically-digested and conventional liquid swine manure, and N fertilizer on crop yield and greenhouse gas emissions
Ammonia Volatilization Anaerobic Digestion
2013/3/4
Anaerobic digestion is a promising technology that could provide an option for managing animal waste with reduced greenhouse gas emissions. A three-year (2006-2008) field experiment was conducted at S...
UQ's Queensland Alliance for Agriculture and Food Innovation (QAAFI) has bolstered its growing reputation for high-impact science by co-developing innovative new crop technology in consort with one of...
