This article evaluates the effect of irrigation on carbonates dynamics in agricultural soils. We studied the proportion and distribution of pedogenic carbonates in different size fractions in a soil with and without irrigation, using the isotopic signature of carbonates C. Irrigation can alter the distribution of soil carbonates and produce a preferential accumulation of pedogenic carbonates (87% to 92% with irrigation for 61% to 74% without irrigation), in the finer fractions.
