The similar [N.sub.2]O emissions in the ON and 140N_U treatments also indicated that mineral N supply from non-fertiliser sources, such as those carried over from the previous season and mineralisation of soil organic matter and cane trash
in the current season, should have supplied sufficient substrates relative to the [N.sub.2]O production capacity through denitrification and/or nitrification under the particular climatic conditions.
On the other hand, the waste of sugarcane crop, which is left in the field and subsequently burnt by the farmers; cane trash
is a biomass source which is available in significant quantities and can be classified as a potent source to produce power.
Agricultural residues which can be used as fuel are: wheat straw, rice husk and straw, cane trash
and cotton sticks and plant residue.
For example, increasing sugar cane trash
retention benefits the environment by reducing the amount of cane that is burnt.
Over the last 25 years, however, sugarcane growers have increasingly adopted a system of green cane trash
blanketing (GCTB), where trash is retained as an undisturbed layer on the soil surface and cultivation is greatly reduced.
Water quality will also be improved by wider adoption of management options such as trash blanket harvesting (retention of cane trash
on fields after harvest), fallow crops rather than bare soil, minimum tillage, avoiding excessive fertiliser and incorporation of fertilisers into the soil to avoid direct run-off of surface-applied nutrients.
This kidney island, poor Ind, which half- slipped on sweets unwrapped, powered with cane trash
, stayed discovery, waits insulin now turns its sweet to plenty turn to the clear inlet pain, filled with Arawak ghosts people a clear glaze, neither slave nor indentured, dead processors of sweets wired its virginity.
Burning hay stacks in England and smouldering cane trash
in Jamaica seem to have little in common beyond the smoke they produce.
Biofuels include plant tissue such as wood and farm waste - the latter include rice husk, rice straw, coffee husk, wheat husk, corn cob, sugarcane bagasse, cotton sticks, cane trash
