Understanding the microbiological and physicochemical influence of alperujo vermicompost on diuron behaviour and soil quality

2009

Vermicompost as soil organic amendment increase the yield crops because improve the soil structure, the water retention capacity, the microbial biodiversity and thereby its metabolic activity. Vermicompost is also thought to reduce the pesticide pollution. The vermicompost selected was composed of “alperujo” which is largest organic residue in olive oil production. Agricultural soil was 5% amended twice and incubated for 3 months. A 3µg g-1 agricultural dosage of Diuron was applied to amended and unamended soils. The effect of alperujo vermicompost on dehydrogenase activity, the biodiversity and estimated bacterial density, the density of protocathechuate-degrading bacterial community and d…
