Conventional solarization and biosolarization with mature compost and tomato processing residue amendments were compared with respect to generation of pesticidal conditions and tomato ( Solanum lycopersicum L.) plant growth in treated soils. Soil oxygen depletion was examined as a response that has previously not been measured across multiple depths during biosolarization. For biosolarized soil, volatile fatty acids were found to accumulate concurrent with oxygen depletion, and the magnitude of these changes varied by soil depth. Two consecutive years of experimentation showed varying dissipation of volatile fatty acids from biosolarized soils post-treatment. When residual volatile fatty acids were detected in the biosolarized soil, fruit yield did not significantly differ from plants grown in solarized soil. However, when there was no residual volatile fatty acids in the soil at the time of planting, plants grown in biosolarized soil showed a significantly greater vegetation amount, fruit quantity, and fruit ripening than those of plants grown in solarized soil.
常规的阳光照射和利用腐熟堆肥和番茄加工残渣进行的生物阳光照射在处理过的土壤中生成农药条件和番茄（Solanum lycopersicum L.）植物生长方面进行了比较。土壤缺氧被认为是一种以前没有在生物阳光照射过程中在多个深度上测量过的反应。对于生物阳光照射的土壤，发现挥发性脂肪酸与氧气耗尽同时积累，这些变化的幅度因土壤深度而异。连续两年的实验表明，生物阳光照射土壤中的挥发性脂肪酸在处理后会逐渐消散。当生物阳光照射土壤中检测到残留的挥发性脂肪酸时，果实产量与在阳光照射土壤中生长的植物没有显著差异。然而，当种植时土壤中没有残留的挥发性脂肪酸时，在生物阳光照射土壤中生长的植物的植被量、果实数量和果实成熟度明显大于在阳光照射土壤中生长的植物。
