Abstract

Objective: To analyze the eﬃciency of organic compounds (cattle manure) in reducing the levels of medium hydrocarbon fraction F2 in a residential soil matrix. Methodology: The experiment was conducted over 18 weeks. The applied doses were T1: 0%, T2: 10%, T3: 20%, T4: 30%, and T5: 40% manure, each with three replicates, totalling 15 experimental units of 2 kg of residential soil, and three sunﬂower seeds used as indicator plants. Results: Cattle manure achieved a reduction in the concentration of the F2 fraction from 6.16% (T1) to 53.61% (T5). Additionally, it improved germination and height development of the sunﬂower compared to the other treatments. Conclusions: Organic amendments such as cattle manure signiﬁcantly reduce the concentration of the F2 hydrocarbon fraction in residential soil, enabling sunﬂower growth.
