Abstract(s)
• The short-term effect of organic residue management on the growth and nutrition of Pinus pinaster
Ait. seedlings, and on nutrient leaching and chemical properties of an acid soil was assessed through a
lysimeter experiment. Treatments included absence, placement on the soil surface, and incorporation
into the soil (with and without legume cover cropping) of organic residues (forest floor litter or forest
floor litter plus harvest residues).
• Residues placed on the soil surface enhanced seedling growth. Organic residues reduced nutrient
losses (NO−
3 , Ca andMg) and resulted in nutrient accumulation in the soil. Harvest residues positively
affected K seedling nutrition status and enhanced K soil accumulation.
• Legume cover cropping reduced soil nutrient losses (N, Ca, Mg and K) during the early stage
of seedling growth; it also improved seedling nutrition status (N and P), but without any effect on
growth.
• Harvest residues plus forest floor litter placed on the soil surface was the most appropriate management
to both reduce nutrient losses through leaching and increase height of seedlings at the end of
the experimental period (two years).
