A methodology for estimating the ammonia emission from crop residues at a national scale

Research output: Contribution to journalArticleAcademicpeer-review

Abstract

Crops and crop residues contribute to pollution of the environment by ammonia (NH 3 ) volatilization. This study focusses on the volatilization from crop residues, defined as residues after a management action or frost i.e. residues that are left on the field after harvest, after killing by use of herbicides or after frost. The objective of this study was to develop a general methodology to calculate the volatilization from crop residues and to estimate their contribution to the NH 3 volatilization at a national scale. A regression model was developed to assess the NH 3 volatilization from crop residue based on the nitrogen (N) content of the residue (emission factor). Information on farm practices (degree of incorporation of residues, the application of crop killing and mowing frequency of grass), harvested crop areas, and N load in crop was used to calculate the emission from crop residues at national scale. The contribution of crop residues to the national NH 3 volatilization in the Netherlands was substantial and calculated at 1.9 million kg NH 3 -N. Grassland contributed about three quarters of total NH 3 volatilization from crop residues. Most volatilization occurs from the mowing losses (54%) and renovation of grassland (14%). Residues of arable crops also have a contribution of 14% to total volatilization. Within arable crops, potatoes are responsible for more than half of the NH 3 volatilization, with the largest contribution from seed potatoes, followed by sugar beet and cabbage crops. NH 3 volatilization from green manure crop residues (killed by freezing or spraying herbicides) is about half the volatilization from arable crop residues (7%). The developed general approach for estimating the NH 3 volatilization from crop residues was applied for the Netherlands but may also be applicable to other countries, taking into account their site specific emission factors and farm practices statistics.
