“…Rate constants from the SFO fitting were used, because they are available for both pesticides in both soils and because one constant covers the whole degradation period. Correlation coefficients (batch approach, r = −0.783; saturated paste approach, r = −0.813) confirm that both constants were inversely related, in agreement with other reports concerning different pesticide families, which have established an inverse relationship between pesticide adsorption and degradation in soils (Di et al, 1998;Sánchez et al, 2003;Prado et al, 2014), suggesting that the degradation rate in the soil solution is more rapid than in the sorbed phase (Guo et al, 2000). In addition, the rate constants (k 2 ) from the fitting to the DFOP model, which explain the decay herbicide behaviour of N85% in S5 and N72% in S2 (Tables 2 and 3), were also inversely correlated with sorption constants (batch approach, r = − 0.792; saturated paste approach, r = − 0.890) (ElGouzi et al, 2012) implying a further confirmation of the previous assumption.…”

“…However in some cases the estimated decay data of both pesticides showed a poor agreement with the measured pesticide concentrations. Deviations from the SFO kinetic model have been reported in the literature (Sánchez et al, 2003;Delgado-Moreno and Peña, 2009;Hernández-Soriano et al, 2009;Herrero-Hernández et al, 2011;Marín-Benito et al, 2012).…”

“…Direct quantification of preferential flow is generally very difficult because of both spatial and temporal varability (Demuth and Hiltpold, 1993). However, lack of correlation between pesticide data obtained from soil and from water samples has been observed and attributed to preferential flow phenomena (Sanchez et al, 2006;Laabs et al, 2000). Additionally, several column, lysimeter, and field experiments indicate rapid, preferential transport of pesticides (e.g.…”

It is not straightforward to sample and demonstrate the presence and transport of pesticides in heterogeneous soil. Following leaching experiments with four differently structured 50-cm-long soil columns (tilled and untilled soil), the objective of this study was to investigate the extent that visual tracing of the dye Brilliant Blue could support in soil sampling for two strongly sorbing pesticides ( 14 C-labeled glyphosate and pendimethalin). About 830 samples were collected. No pesticide was found below 10-25 cm depth by random sampling, even though 0.21-0.31% of the applied amounts were leached, and 0.18% of the soil volume was sampled. With similar sampling efforts, the pesticides could generally be traced throughout the columns by sampling from stained soil volumes, only. None of the two particular sampling strategies for pesticides produced accurate mass balances or balances that were obviously better than the other. No pesticide was detected outside stained soil volumes, except for glyphosate in one sample. Below 30 cm, stained soil comprized on average 5% of the total soil volume, leaving 95% as expectedly pesticide-free. The results suggest that much more efficient sampling for sorbing pesticides can be obtained by using the dye and focusing on stained soil volumes.

“…On the contrary, Graber et al [7] observed a sustained enhanced effect on atrazine and terbuthylazine transport in a field amended with sewage sludge, whereas bromacil was preferentially accumulated in the upper soil layers of the sludge amended soil. Sánchez et al [8] found no effect of biosolid amendment on methidation mobility.…”

The aim of this work was to study the effect of the application of a solid waste from olive oil production (alperujo) on the movement and persistence of the herbicide diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea]. The application of alperujo, fresh or composted, to the land has been shown to be an extremely effective contribution to increasing crop yields and to maintaining or improving soil fertility. An experimental olive grove located in Mengibar (Jaen, Spain) was divided into two plots: 1. Plot without organic amendment (blank) and 2. Plot treated with alperujo during 3 years at a rate of 17920 kg of alperujo ha -1. Diuron was applied to both plots at a rate of 2 kg ha -1 a.i. Triplicates from each plot were sampled at three depths (0-10, 10-20 and 20-30 cm), air-dried, remains of olive leaves, grass roots, and stones removed and sieved through a 5 mm mesh sieve. Diuron was extracted with methanol 1:2 weight:volume ratio, the extracts were evaporated to dryness, resuspended in 2 mL of methanol, filtered and analyzed by HPLC. Higher amounts of diuron were detected at each sampling depth in plots treated with alperujo. The increase in soil organic matter content upon amendment with alperujo slightly increased sorption, suggesting that other factors beside sorption affect diuron degradation rate in organic amended soils.
