Maize response to K and gypsum in acid soils of Chiapas, Mexico

IPNI-2016-MEX-62

This Canpotex-supported project, was carried out in cooperation with Mexico's National Agricultural Research Institute (INIFAP) and the International Maize and Wheat Improvement Center (CIMMYT). The project began in 2016 to fine-tune potassium (K) and gypsum rates for maize production in the acid soils of La Frailesca (Chiapas). Four K application rates (0, 60, 120, and 180 kg K2O/ha) and four gypsum application rates (0, 1. 25, 2. Read more
