“…This is consistent with the results of a previous field study on diuron in which the amount of diuron recovered increased significantly in the 7 years of amending the soils with OW, compared to unamended soils. The present results also agree with those of previous reports indicating increased persistence of terbuthylazine in soils treated with different organic amendments (Cabrera et al , 2009Navarro et al 2003;Dolaptsoglou et al 2009). Although the increases in persistence obtained with OW Fig.…”

“…These results are not coherent with those of the leaching studies (see Fig. 3), indicative of the differences between disturbed and undisturbed systems when assessing the leaching behaviour of pesticides in soils (Cabrera et al 2009). Moreover, the presence of inert ingredients (20%) in the commercial pesticide used in the field experiments, together with the large total amount of 0.01 M CaCl 2 added in the laboratory columns (equivalent to 1,476 mm) compared with the weak rainfall observed over the complete period of the field study (total amounts of 166.8 and 172.9 mm for 2005 and 2007, respectively), would also have contributed to the observed differences in the results under controlled or field conditions.…”

“…As with other organic wastes, using OW as soil amendment could be an effective management practice to control pesticide leaching (Albarrán et al 2003;Cabrera et al 2007Cabrera et al , 2009.

Influence of two-phase olive mill waste application to soil on terbuthylazine behaviour and persistence under controlled and field conditions

Purpose Terbuthylazine is one of the most common herbicides used to control weeds in olive groves. Application of two-phase olive mill waste (OW) to soils may play a fundamental role in the management of leaching losses of pesticides, especially in Mediterranean areas where soils are characterized by low organic matter levels. We evaluated the impact of OW amendments on the sorption-desorption, degradation, leaching, and persistence of the herbicide terbuthylazine in a representative olive grove soil from Portugal. Materials and methods The soil was amended in the laboratory with OW at the rates of 5% and 10% (w/w), and in the field at the rates of 0.7% and 1.4% of OW for 7 years. Cumulative and residual effects were evaluated in the last year and 2 years after the last OW field application. A batch equilibration method was used to determine terbuthylazine adsorption-desorption. Leaching experiments were studied in hand-packed soil columns. Half-lives (t 1/2 ) were calculated with incubation studies. In the field study, in order to determine the persistence and distribution of terbuthylazine down the soil profiles, at selected times after the herbicide application, soil subsamples were taken from different soil depths. Results and discussion The OW amendments significantly increased the adsorption of terbuthylazine to the soil. Applications of OW to soil significantly reduced the amount of terbuthylazine leached in the field-amended soil columns, with a major residual decrease (from 19.6% to 2.9% at the greater application rate) 2 years after the last OW application. Leaching losses of the herbicide, however, were increased by up to 69.3% for the laboratory-amended soil columns, mainly promoted by an increase in watersoluble organic carbon content. Addition of OW retarded the degradation of terbuthylazine from 6.7 days for the unamended soil to 15.7 and 89 days at the greater application rate in the field-and the laboratory-amended soils, respectively. In the field study, OW addition decreased terbuthylazine's vertical movement through the amended soils with increasing OW rate.Conclusions The study has shown that OW amendment of olive grove soils may be an effective management practice for reducing the vertical movement of terbuthylazine through the soil. However, leaching loss of this pesticide could potentially increase in fresh OW-amended soils, especially if humification of the organic matter is not favoured. In addition, the use of OW could also increase the risk of surface water contamination, especially if application rates are greater than 30 tha −1 .

Bentazone and S‐metolachlor are herbicides widely used for the control of broad leaf weeds in crops such as corn and soybean. The effect of the addition to soils with different texture and organic matter content of an organic waste (OW) from oil olive production (alperujo) on different processes affecting behaviour of both herbicides was evaluated. Sorption of S‐metolachlor increased upon amendment. A six‐fold increase could be observed for Kd values on the sandy soil amended at 10% rate and a five‐fold increase on the soil with higher content on clay (48%) and same rate of OW (10%). The results revealed that although an increase in soil total pore volume was found upon amendment (from 210 to 266 mm3 g−1 in sandy (S) soil, from 215 to 251 in clayey (19% silt) (T) soil, and from 240 to 289 in clayey (50% silt) (E) soil), leaching of the herbicide S‐metolachlor was greatly reduced (from 61 to 3.5% in the S‐soil and from 37 to <1% in the clayey T‐soil) since its behaviour in soils is strongly affected by sorption processes. Bentazone leaching was only slightly delayed upon amendment. Half‐life of both herbicides also increased upon amendment. The greatest increase was observed with the higher rate of OW (10%) in the soils with higher content of clay (48% in T‐soil and 31% in E‐soil). A 17‐fold increase was observed for S‐metolachlor half‐life in T‐soil and a four‐fold increase for bentazone in E‐soil. Thus, the use of the by‐product from olive oil extraction can be a good strategy to reduce the off‐site movement of S‐metolachlor by increasing its soil sorption, and therefore the risk of water pollution can be diminished. However, the higher persistence of both herbicides in organic amended soils should be taken into account.
