Effect of irrigation on carbonate dynamics in a calcareous soil using isotopic determinations


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.
