BAUTISTA-CRUZ, Angélica; CRUZ DOMINGUEZ, Gricel  and  RODRIGUEZ-MENDOZA, María de las Nieves. Effect of Bocashi and slow release fertilizers on some soil properties with corn. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.1, pp.217-222. ISSN 2007-0934.

In this study the effect of individual or combined application of compost (bocashi, B) and slow-release fertilizers (FLL) on some soil properties of terrace and valley, cultivated with maize (Zea mays L.) in the Mixteca region from the state of Oaxaca, Mexico was determined. A completely randomized design with 7 treatments and 4 replications was used: control without fertilization (C); conventional fertilizer (90-46-00 NPK) (FC); B; FLL1 [Multigro 6^®, 21-14-10 NPK]; FLL2 [Multigro 3^®, 24-05-14 NPK]; B + FLL1; B + FLL2. On the soil from the valley, pH decreased and the content of available P increased with FLL2. On terrace soil, pH decreased with FLL2, and content of available P increased with B + FLL2. The microbial biomass carbon (CBM) increased with B in both soils. The significant effect of fertilization × soil type interaction indicated that the response of available P and CBM to fertilization was influenced by the soil type. The results suggest that individual application of FLL2 and B can improve pH, available P and CBM in soils cultivated with maize.

Keywords : Zea mays L.; available P; fertilizer; microbial biomass carbon; pH.
