An experimental site will be developed in Field 2B (UC-Riverside AgOps) to test the effectiveness of using solar heat pulsing to sterilize soils in preparation for planting various specialty crops. The experimental design will include standard 40” raised beds and have a bare-soil control and three solarization treatments with three replicates. Soil temperatures and heat flux throughout the raised-bed will be measured for several weeks. Various meteorological measurements will be made to allow determination of the solar energy input to the experiment. Several plant pests will be placed in the beds, be subjected to solarization for 4-6 weeks and then assayed for survival. After the solarization period, the plots will be fumigated with approximately 40% and 70% of the standard rate of Telone Inline to determine if pest control improvement occurs. The experiment will also include a negative control (no solarization, no fumigation) and standard fumigation treatments. Once the data is available, a modeling study will be conducted to investigate the heat transport and fate and transport of fumigant chemicals in the soil beds. Formerly 5310-12130-008-04S (11/10).
