Antonia Pérez-Olvera Multidisciplinaria (Ciencias Naturales y Exactas) carbon nitrogen residues potassium phosphorus Introduction: Nutrition management in the maize crop in Guanajuato, Mexico, is based on mineral fertilization, with high doses of nitrogen and reduced application of phosphorus and potassium. Objective: To diagnose the management of mineral nutrition and residues from the maize cropping system, and identify opportunities for their efficient use. Methodology: 68 maize farmers from the municipalities of Salvatierra and Valle de Santiago, Guanajuato, were surveyed. Plot soils were sampled, and yield, nutrient concentration and C mineralization were estimated. With the data obtained, graphs of the balance of N, P, K and C were made.Results: Nutrition management and biomass production varied among farmers. Currently, P and K are not limiting factors, unlike N, since the soil only contributes 11 % of the total available nitrogen. Residue management showed that there is an imbalance between soil C mineralization and the incorporation of residues.Study limitations: The analysis focused on only one agricultural cycle.Originality: The focus of the study, including the graphical analysis, is scarcely applied in the region’s maize farming systems. Conclusions: An integral vision is required for the management of organo-mineral nutrition and residues to contribute to their efficient and sustainable use. 2019 artículo científico 2007-3925 https://www.redalyc.org/articulo.oa?id=688672145001 https://www.redalyc.org/journal/6886/688672145001/ https://www.redalyc.org/journal/6886/688672145001/html/ https://www.redalyc.org/journal/6886/688672145001/688672145001.epub https://www.redalyc.org/journal/6886/688672145001/movil 10.5154/r.inagbi.2017.11.017 en http://www.redalyc.org/revista.oa?id=6886 Ingeniería agrícola y biosistemas application/pdf Universidad Autónoma Chapingo Ingeniería agrícola y biosistemas (México) Num.2 Vol.11 |
