Recycling to soil Olive Mill Waste (OMW) has the potential to improve soil fertility, thus reducing CO2emission associated to global warming. However, the short period in which OMW are produced and thehigh load of recalcitrant compounds, make difficult direct land spreading of raw OMW. Consequently,sustainable biological treatments able to transform OMW into a safe amendment have been progressivelydeveloped.In comparison to a standard mineral fertilization, the present work assessed the agronomic performanceof two innovative kinds of OMW compost, used as fertilizers in Lactuca sativa and Lycopersiconesculentum cultivation trials. Both crops showed yields comparable to control, thus suggesting that mostof the nutrients contained in the OMW supported adequately plant growth, even in short-term crops. Sixmonths later OMW application, no significant differences were found in the soil humic content.

Abstract
Recycling to soil Olive Mill Waste (OMW) has the potential to improve soil fertility, thus reducing CO2emission associated to global warming. However, the short period in which OMW are produced and thehigh load of recalcitrant compounds, make difficult direct land spreading of raw OMW. Consequently,sustainable biological treatments able to transform OMW into a safe amendment have been progressivelydeveloped.In comparison to a standard mineral fertilization, the present work assessed the agronomic performanceof two innovative kinds of OMW compost, used as fertilizers in Lactuca sativa and Lycopersiconesculentum cultivation trials. Both crops showed yields comparable to control, thus suggesting that mostof the nutrients contained in the OMW supported adequately plant growth, even in short-term crops. Sixmonths later OMW application, no significant differences were found in the soil humic content.File | Dimensione | Formato | |
