Resumen:
Soil ecosystem provides fundamental services as biogeochemical cycle
regulation. Nitrogen cycle is managed by the microbiota that it harbors
and depends on the stability of the ecosystem to cope abiotic
disturbances such as metal and metalloid contamination. High
concentrations of nickel (Ni) and zinc (Zn) in agricultural soils are
frequently related to the application of conventional farming practices,
composting, irrigation and biosolids deposit, as well as wastewater
polluted from the mining and thermoelectric industry. To better
understand the effects of this kind of abiotic disturbance a microcosm,
this study was performed with agricultural soil from the Coast of
Hermosillo, Sonora, Mexico and contaminated with Ni (II) and Zn (II)
salphen complexes to evaluate their effect on the system, regarding the
nitrogen cycle fluxes over time. The results obtained by
spectrophotometric analyzes of the inorganic nitrogen pool, atomic
absorption and pH revealed that the soil system functioning based on the
nitrogen cycle was recovered 240 days after disturbances with M-salphen.
This suggest the potential use of NiSB15 as a promoter to increase
nitrate concentration at 60 days in conjunction with NiSA15 to increase
ammonium concentration in agricultural soils contaminated with heavy
metals.
