YAULILAHUA-HUACHO, Russbelt et al. Analysis of the growth of Trifolium repens cultivated on artificially created mining liabilities as a remediation strategy. Rev. Inv. Cs. Agro. y Vet. [online]. 2024, vol.8, n.23, pp.414-423.  Epub 02-Maio-2024. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v8i23.274.

Mining environmental liabilities generate soil degradation and water pollution; Therefore, the use of organic matter and humus as stimulants and plants with high biomass production that extract contaminants through their roots. Hence, the objective was to evaluate the germination and growth of white clover grass (Trifolium repens) in mining passives, with the addition of black soil and compost as substrates. The study was carried out at the Buenaventura Julcani Huancavelica Company. The treatments studied were: T1 (pure tailings), T2 (pure tailings and black earth), T3 (pure tailings and compost), T4 (pure tailings, black earth and compost) in combinations. of 4: 3.1: 3.1: 3:1.1 with a total of twelve experimental units. A completely randomized design (CRD) with a 1 x 4 factorial arrangement was used, considering twelve repetitions in each treatment. The results, in germination of Trifolium repens seeds after 18 days, a germination percentage of 31 ± 7 was obtained in treatment one of pure tailings (control group), 55 ± 10 in treatment two of pure tailings and black earth. , 26 ± 10 in treatment three of pure tailings and compost, and 41 ± 9 in treatment four of pure tailings, black earth and compost, for Trifolium repens seeds. The combination of pure tailings, black soil and compost improves germination compared to the control group and treatment three, but does not reach the effectiveness of treatment two.
