targeted to fertility preservation. This study was aimed to assess the cumulative
effect of mineral fertilization and of the incorporation of increasing doses
of composted olive pomace on the sandy-loam soil. The trial involved a split-plot
design with 3 replicates and was aimed at comparing 2 types of compost (in large
plots), the untreated control (0), mineral fertilization (Min), the conditioner
made from composted olive pomace at the rates of 15-30-45-60 mg ha-1
of dry matter and the integration of 30 mg ha-1 with ½
of the N rate used for the Min treatment. As compared to the non-conditioned
soil, the spreading of 60 mg ha-1 leads to increase organic matter
by 100%, total nitrogen by 1.29 g kg-1, available phosphorus by 11.5
g kg-1, exchangeable potassium by 251 mg kg-1. Moreover,
the land spreading with increasing doses of olive pomace seems to increase the
structure stability index (+71% without pre-treatment and+30% with alcohol pre-treatment)
favoring particle aggregation. This leads to improve pore distribution, which
is extremely important for hot arid environments where soils have depleting
organic matter levels so they are more and more de-structured. The application
of composted olive pomace as fertilizer has been an effective alternative to
mineral fertilization and a valuable tool to achieve a threefold objective:
storing carbon in the soil, improving soil quality and reducing the environmental
impacts associated with the disposal of organic materials.]]>Albiach, R., R. Canet, F. Pomares and F. Ingelmo,200177109114Alfano, G., G. Lustrato, G. Lima, D. Vitullo, C. Colombo, S. Delfine, R.
