Gypsum and potassium application to acid soils for maize (Zea mays L.) production in La Frailesca, Chiapas, Mexico

Introduction. Maize (Zea mays L.) production in La Frailesca region, Mexico, is limited by sandy soils, low in potassium (K), and with acidic arable layers and subsoils. There is information on the management of lime but not on amendments that could be used for subsoil acidity — such as gypsum — nor...

Maize (Zea mays L.) production in La Frailesca region, Mexico, is limited by sandy soils, low in potassium (K), and with acidic arable layers and subsoils. There is information on the management of lime but not on amendments that could be used for subsoil acidity — such as gypsum — nor on the interactions between amendments for soil acidity and K fertilization. Objective. To evaluate the effects of K and gypsum on maize and on previously limed soils. Materials and methods. The evaluations were conducted in farmers’ fields in La Frailesca region, Chiapas (Mexico) in 2016 and 2017. Four gypsum rates (0, 1.25, 2.5 and 5 t ha-1) and four K rates (0, 60, 90, and 120 kg ha-1 as K2O) were factorially combined in a randomized block design, with three replicates. In both years, before the beginning of the experiments, dolomitic lime was applied to the experimental area following standard practices. Responses of crop yield, soil exchangeable K, Ca, Mg, and Al, and soil pH were obtained. Results. Maize yields increased with gypsum (stabilizing at 1.25-3.0 t ha-1), and K (stabilizing at 70-120 kg ha-1 of K2O) applications. In soils, K application increased exchangeable K content, while gypsum increased exchangeable Ca content and pH, and decreased exchangeable Al content. Liming increased pHCa and exchangeable Ca and Mg contents, and lowered the exchangeable Al content in the top 7.5 cm of soil. Conclusion. Soils with exchangeable K (≤0.3 cmolc kg-1) were responsive to K fertilization. The positive effects on yields from gypsum were probably linked to a greater Ca supply in the top 7.5 cm. These results are encouraging about the benefits of the combined application of dolomitic lime, gypsum, and K, but longer evaluations are needed to properly determine the effects of gypsum on subsoil acidity.Universidad de Costa Rica2022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdf2215-3608https://www.redalyc.org/articulo.oa?id=43768481015https://www.redalyc.org/journal/437/43768481015/https://www.redalyc.org/journal/437/43768481015/html/https://www.redalyc.org/journal/437/43768481015/43768481015.epubhttps://www.redalyc.org/journal/437/43768481015/movilhttps://doi.org/10.15517/am.v33i1.46173Agronomía Mesoamericana (Costa Rica) Num.1 Vol.33reponame:Redalyc-INIFAPinstname:Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuariasinstacron:INIFAPenhttp://www.redalyc.org/revista.oa?id=437Agronomía Mesoamericanainfo:eu-repo/semantics/openAccessoai:redalyc.org:437684810152026-01-29T02:34:44Z
