CABRERA, A. et al. Study of the effect of olive mill waste "alperujo" addition on the persis­tence of diuron in olive groves. []. , 33, 1, pp.209-216. ISSN 0871-018X.

The aim of this work was to study the ef­fect of "alperujo" (olive mill waste) on the persistence and the mobility of the herbicide diuron [3-(3,4-dichlorophenyl)-1,1-dime­thylurea] in an olive grove from Mengíbar (Jaén, Spain). The plot was divided in two subplots, one where no amendement was applied and another one where "alperujo" was applied to the soil (18.000 kg ha^-1). Af­ter herbicide application at a rate of 2 kg/ha, three replicates of soil were sampled at each subplot, at different depths and different days after diuron application. After drying, cleaning and sieving samples diuron was extracted with methanol and the extracts were analyzed by HPLC. Higher amounts of diuron were recovered from amended soil than from non amended soil in every sam­ple. However, diuron mobility in amen-ded soil did not increase with time.
