Research Project: REDUCING EMISSIONS OF VOLATILE ORGANIC COMPOUNDS FROM AGRICULTURAL SOIL FUMIGATION Project Number: 5310-12130-009-03
Project Type: Reimbursable

Start Date: Jun 30, 2008
End Date: May 15, 2012

Objective:
(a) Test several low-cost approaches to measure reduction of emissions from soil fumigation that could help guide air quality regulation. (b) Obtain information needed to support the use of the new methodology. (c) Compare results from low-cost approaches to the currently accepted large-scale field study approach.

Approach:
The goal of this project is the development and demonstration of simple, low-cost, and accurate methodology that can be used in place of currently mandated approaches to obtain fumigant emissions estimates. Essentially, laboratory and modeling studies will be carried out using soils from the Buttonwillow, CA field site, and compated directly to the previously completed field experiments. As in the field experiment, the simplified methodologies will be applied to current fumigation practices and to new reduced-emission strategies. Additionally, a wide range of additional emission reduction strategies will also be assessed, with some of these experiments to be determined in collaboration with California ARB and stakeholder groups. A principle advantage to carrying out so many, differing, studies at a single site will be that our understanding of the important processes controlling fumigant fate and transport will not be clouded by inter-site differences, which has been a problem in previously conducted studies. Documents Reimbursable Agreement with the California Air Resources Board. Log 37397. Formerly 5310-12130-008-05R. (11/10).
