this work investigates the effect of the application rate and type of sludge throughout the soilcarbon cycle in a semiarid mediterranean agro-ecosystem. we study the two-year evolution of the variouspools of soil organic and inorganic carbon and their influence on soil respiration. we applied three rates (40, 80 and 160 mg/ha) of two types of sludge –aerobically and anaerobically digested sewag...

This study investigated the formation and plant uptake of lipophilic metal-rhamnolipid complexes. Monorhamnosyl and dirhamnosyl rhamnolipids formed lipophilic complexes with copper (Cu), manganese (Mn), and zinc (Zn). Rhamnolipids significantly increased Zn absorption by Brassica napus var. Pinnacle roots in (65)Zn-spiked ice-cold solutions, compared with ZnSO4 alone. Therefore, rhamnolipid app...

A number of studies have reported the beneficial effects of the organic matter on the bioavailability of P in different soil types. These effects have been attributed to several factors, including the possible formation of phospho-metal-humic complexes, which could protect P from retrogradation in both acid and alkaline-calcareous soils. However, the experimental evidence supporting the existen...
