Surface barriers such as extremely low permeability plastic films will be used under field conditions to enhance pest nematode control and reduce fumigant emissions to the air. Soil amendments with natural organic materials such as animal manure or synthetic chemicals will be evaluated alone or in combination with the low permeability films to enhance fumigant decomposition thus reducing emission potential and protect air quality. Application of fumigants with irrigation systems will be tested in comparison with shank injection methods and potential for deep percolation and surface runoff will be evaluated. Impact of soil organic and inorganic amendments on air and water quality will also be measured. Documents SCA with UC Riverside.
