摘要：

The existing predictions of the changes in the yield of agricultural crops depending on the expected climatic scenarios for the end of the 21st century are usually performed without consideration for the soil fertility alteration under the effect of the climate changes. This work deals with an attempt to assess the effect of the possible changes of the fertility of agricultural soils on the yield of corn and wheat under non-irrigation conditions with reference to the predicted scenario of climate changes at the doubling of the CO(2) in the atmosphere at the end of the 21st century. Studies were performed for typical regions of growing these crops in different climatic zones of Mexico.
