In addition, the large amounts of cane trash
retained on the soil surface were found to increase [N.sub.2]O, most likely by acting as a source of biologically available C and N and maintenance of wet soil conditions due to reduced evaporative water loss (Wang et al.
The other waste, cane trash
constitutes 10 percent of the sugarcane crop.
Leaving aside wastages - 9% cane trash
for power generation.
Ng Kee Kwong KF, Deville J, Cavalot PC, Riviere V (1987) Value of cane trash
in nitrogen nutrition of sugarcane.
Several trial sites examining the effect of these systems have now been operating for ~10 years, making it possible to assess the effect of green cane trash management in combination with NT on TOC stocks.
This study examined the effect of NT and/or green cane trash management on TOC stocks at four sugarcane trial sites in Queensland, Australia, to assess the potential of these management practices to increase soil carbon sequestration in sugarcane soils over 0-0.1 and 0-0.3 m depths.
Agricultural resi-dues which can be used as fuel are: wheat straw, rice husk and straw, cane trash
and cotton sticks and plant residue.

Soil samples were collected in 1995 from the long-term green cane trash
blanket trial which is being conducted on a Typic Tropaquept soil at the Tully Experiment Station, Queensland.
