Nitrogen runo
Year:
2012
Author:
Riccardo Pravettoni, UNEP/GRID-Arendal
Description:
Fertiliser and pesticides used to cultivate feedstocks, as well as contaminated effuents discharged from conversion
plants, can cause increasing levels of pollution to
waterways. This may constrain the growth of biofuels
production in developed and developing countries
with already high agricultural production levels.
An example illustrates the level of nitrogen
persistent in various regions of the United States
and agrochemical use for different feedstocks.
