Resumen

In Camaguey, Cuba there is an surface chrome mine in need of restoration; the search for viable alternatives is an urgent need. One alternative used is initial micro organic stimulation of the soil with mineral fertilizers. However, due to the high costs of the procedure, organic sources were tried, as replacement for inorganic fertilizers. An experiment was set up at the Soil Laboratories, in Camaguey, Cuba, under semi-controlled conditions. A completely randomized design and six treatments were applied (mining sterile, ferromagnesial brownish-red fersialitic soil, originally found in the mine, from an unaltered area, mining sterile mixed with soils, manure (cattle or chicken), and a treatment using a mixture of mineral fertilizers: ammonium sulfate plus triple superphosphate, to determine the best microbiological variant. The results showed that the mining sterile was highly degraded, in comparison to the soils previously found in the site. The mixtures that contained organic fertilizers had higher microbial development, especially a treatment that included chicken manure.
