Pomaces from tomato paste and wine production are the most abundant fruit processing residues in California. These residues were examined as soil amendments for solarization to promote conditions conducive to soil disinfestation (biosolarization). Simulated biosolarization studies were performed in both aerobic and anaerobic soil environments and soil temperature elevation, pH, and evolution of CO2, H2 and CH4 gases were measured as metrics of soil microbial activity. Tomato pomace amendment induced conditions associated with soil pest inactivation, including elevation of soil temperature by up to 2°C for a duration of 4days under aerobic conditions and a reduction of soil pH from 6.5 to 4.68 under anaerobic conditions. White wine grape pomace amendment showed similar trends but to a lesser extent. Red wine grape pomace was generally less suitable for biosolarization due to significantly lower soil temperature elevations, reduced acidification relative to the other pomaces and induction of methanogenesis in the soil.
番茄酱和葡萄酒生产过程中产生的果渣是加利福尼亚州产量最大的水果加工残余物。这些残余物被作为土壤改良剂用于太阳能消毒，以促进有利于土壤除害（生物太阳能消毒）的条件。在有氧和无氧土壤环境中都进行了模拟生物太阳能消毒研究，并测量了土壤温度升高、pH值以及二氧化碳、氢气和甲烷气体的释放情况，以此作为土壤微生物活性的指标。番茄果渣改良剂引发了与土壤害虫失活相关的条件，包括在有氧条件下土壤温度在4天内升高多达2°C，以及在无氧条件下土壤pH值从6.5降至4.68。白葡萄酒葡萄果渣改良剂呈现出类似趋势，但程度较小。红葡萄酒葡萄果渣通常不太适合进行生物太阳能消毒，因为其土壤温度升高明显较低，相对于其他果渣酸化程度降低，且会在土壤中引发甲烷生成。
