CORAS MERINO, Pablo Miguel; ONTIVEROS CAPURATA, Ronald  and  DIAKITE DIAKITE, Lamine. Groundwater flow and concentration of salts in agricultural soils. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.4, pp.537-548. ISSN 2007-0934.

In rainy periods 223.8 ha in San Martín Nezahualcóyotl, Mexico State, have problems with excess moisture and high concentrations of soluble salts in the soil layers and groundwater, which vary throughout the year with fluctuations of the water table res ulting in low crop yields. Isobaths planes were developed in this work, to locate areas of excessive moisture, 1 sohypsess how the di re cti o ns and move me nt o f groundwater flows and isos ali nity in s oil profiles. Water table oscillation was determined by analyzing 27 samples of soil and water per year over the period 2006-2011. It was found that rains in August (33 mm) and September (100.5 mm) cause the rise of the water table and excess water in the soil at 0.58 ha to 0.65 ha per mm of rainfall in 223.8 ha. In water tables over 1.51 m deep, soils had low salinity and sodicity (72.36 ha). In water tables less than 1.5 mm deep and groundwater medium to high in salts, saline soils and / or sodic soils were found, covering 59 ha (26 %) of the total area.

Keywords : rainfall; salinity; water table.
