JUAREZ-RODRIGUEZ, Lucia et al. Sustainable soil management for organic vegetable production in the State of Mexico. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.6, e3395.  Epub 17-Mar-2025. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i6.3395.

A growing number of farmers in the east of the State of Mexico produce healthy, quality food that they sell in local organic markets. Their agricultural practices have been poorly evaluated, and there is a risk that long-term intensive food production will result in decreased soil fertility and productivity. The effect of the application of organic fertilizers on Brassica rapa L. var. chinensis (pak choi) and Brassica oleracea L. var. acephala (kale) in two growth cycles (spring-summer and autumn-winter) and on the chemical quality of the soil was studied. The field experiments were carried out in the municipalities of Teotihuacán and Texcoco, State of Mexico. The experimental design was randomized blocks. The treatments tested were compost 10 t ha-1, compost 10 t ha-1 + 4% supermagro, 4% supermagro, and a control without application. Variables of morphological response, crop yield, and soil chemical quality indicators (pH, electrical conductivity, organic matter, NKjeldahl, POlsen, and K, Ca, Mg, and Na exchange bases) were evaluated. The results were analyzed using the SAS 9.0 statistical package. In both sites, applying these organic fertilizers increased the commercial yield of both vegetables and some morphological variables. The treatments experimented improved, or at least maintained, the initial fertility of the soils in the short term.
