      abstract     = {Spanish olive oil groves are undergoing a marked change in
                      the way that inter-row land is managed. The current
                      recommendation encourages the use of plant cover to increase
                      plant residue input to the soil to improve fertility and
                      reduce erosion. However, there is no quantitative
                      information on the temporal trend and magnitude of nutrient
                      release during decomposition of plant cover residues after
                      the annual topping of vegetation. Decomposition rates and
                      nutrient dynamics (C, N, P and K) were examined for
                      aboveground residues from two types of plant cover (a sown
                      legume and ruderal plant species) and in fine roots.
                      Litterbag experiments were designed to evaluate the effects
                      of the type and location of plant residues (above- or
                      belowground) by placing litterbags of aboveground plant
                      residues on the soil surface or within the soil, which were
                      sampled over a whole year. The highest decomposition rates
                      for above- or belowground residues were found in spring, and
                      were higher for buried plant residues, regardless of plant
                      cover type. After one year, the remaining C, K and P in the
                      soil was about $30\%,$ $20\%$ and $30\%$ of that added,
                      respectively and therefore plant cover could be a useful
                      strategy to improve C sequestration and increase soil
                      nutrient content in olive groves. Decomposition of plant
                      residues left on the soil surface immobilised N, whereas
                      this was not the case when they were buried. The remaining
                      C, N, P and K content in belowground residues was similar to
                      aboveground samples with around $21\%,$ $27\%,$ $23\%$ and
                      $15\%,$ respectively. This study highlighted the importance
                      of plant cover for retaining nutrients when tree demand was
                      low, but releasing a significant proportion of the nutrients
                      in early spring when tree demand was high, especially when
                      residues were incorporated into the soil.},
