Abstract:
In this study, effects of olive oil solid waste (OSW) applications on bean and sunflower macro and micro
element contents were investigated. Olive oil solid waste mixed with soil at the rates of 0, 3, 5 and 7 % by
weight. Plants were grown in the pots under controlled conditions throughout 45 days for sunflower and 30 days
for bean. Plant carbon/nitrogen (C/N), some macro elements; nitrogen (N), phosphorus (P), potassium (K),
calcium (Ca), magnesium (Mg), and micro elements; boron (B), iron (Fe), manganese (Mn) contents were
determined and their relations with the application of olive oil solid waste have been investigated. As a result,
while phosphorus, calcium, and boron have increased, nitrogen has decreased in sunflower plants. On the other
hand, phosphorus, potassium, magnesium, and boron have increased but nitrogen, calcium, and manganese have
decreased in bean plants.
