11. Sustentabilidad del riego complementario en suelos Udipsament Típico y Hapludol Entico de Argentina
The complementary irrigation with high level of sodium in water leads to dispersive processes that deteriorate the porous space and therefore, other related properties. This could take place with low to medium levels of SAR of water, in coarse soil in which the illite is predominant in the clay fraction. It is hypothesized that irrigation may cause dispersiv
