A detailed description of the climate at different locations in Argentina has been provided by the National Institute of Agricultural Technology (INTA, 2011). In general, precipitation decreases from east to west and from north to south along the country, with the highest temperatures occurring in the northern regions and the lowest occurring in the south. However, the pre–Cordillera and Cordillera de los Andes across the Semiarid and Arid regions could be very cold from north to south. Most beef cattle are found in the Pampeana region (64% of total cattle inventory), which is also the most relevant area for grain and oilseed production
