Maize response to dolomitic limestone, gypsum, and potassium in La Frailesca, Chiapas (Mexico)

IPNI-2015-MEX-60

This project is a continuation of IPNI-2014-MEX-57. Two dolomitic limestone application rates (0 and those calculated on the basis of percent of exchangeable Al (Al-exch), two gypsum rates (0 and 5 t/ha), and two K2O rates (0 and 120 kg/ha) were added in a complete factorial design, with three replications, at four locations with soils that had average pH 4. 4, 0. 08 cmol K/kg, 0. 4 cmol Ca/kg, 0. 1 cmol Mg/kg, and 67% Al-exch in the top 15 cm, and pH 4. 6, 0. 05 cmol K/kg, 0. 7 cmol Ca/kg, 0.
