Abstract:
Aim of the current paper is the monitoring of feedstock losses during the six months storage of harvested olive tree prunings (OTP), by comparing two storage solutions: i) uncovered, open-air storage and ii) covered storage. For this task, two identical conical piles of harvested prunings were built and monitored for calculating the changes in dry matter and energy content of the stored material over time. One pile was built as-is and the other was covered with a fleece. For each pile, sample bags were used in order to monitor the alterations in dry matter and energy content of the stored OTP. In overall, the covered pile showed greater storage performance than the uncovered pile, where the latter depended mostly on weather conditions. The covered pile presented lower dry matter losses after 6 months of storage (average value of 1.1 % compared to 4.6 % of the uncovered pile), stable moisture content throughout the storage period (around 10 % compared to fluctuating moisture content of uncovered pile from 11 % to 21 %), that also resulted in energy content gain (average pile value of energy content gain of 12.1 % compared to energy content loss of 5.1 % of the uncovered pile).
