composted olive mill by-products: compost characterization and application on olive orchards

Olive Mill By-Products Management

olive mill by-products application: organic olive orchard yield performance and soil fertility

seasonal accumulation and incorrect disposal of olive mill by-products may be detrimental to the environment. conversely, their proper recycling as soil amendments may be a sustainable solution. therefore, the objectives of this three-year field trial were: (i) investigating the effects of olive mill wastewater (omw) and pomace compost (pc) on plant nutritional status and yield in an organic ol...

Effects of application of olive mill by-products on chickpea yield and their symbiosis with mycorrhizal fungi under arid conditions

This study investigated the effects of soil amendment with olive mill by-products (Jift) on growthof chickpea and their symbiosis with Vesicular arbascular (VA) fungi. A split plot design with threereplications was used, in which soil treatments (methyl bromide fumigated, fungicide, and untreatedcontrol) were assigned to main plots and soil-Jift mixtures(Jift: Soil; 0:10, 1:9, 2:8, 3:7, and 4:6...

Long Term Amendment with Fresh and Composted Solid Olive Mill Waste on Olive Grove Affects Carbon Sequestration by Prunings, Fruits, and Soil

The soil amendment with organic wastes represents a way to increase the soil fertility and the organic carbon (C) stored in the agro-ecosystems. Among the organic waste materials produced by agricultural and industrial activities, olive mill wastes derived from the olive oil extraction process may represent a suitable soil amendment. The aim of the study was to evaluate the effect of fresh (SOM...

Antimicrobial Activity of Olive Mill Waters (Alpechin) and Biotransformed Mill Wastewater Waste- Olive Oil

Olive oil extraction produces a great volume of residue. These olive mill wastes are known as alpechin. This wastewater is a powerful pollutant, resistant to degradation and presents a severe environmental problem related to its high organic content made up largely of simple phenolic compounds, that have been described as being both antimicrobial and phytotoxic. This paper reviews briefly the a...

Potential of olive mill waste and compost as biobased pesticides against weeds, fungi, and nematodes.

The phytotoxic and antimicrobial properties of olive mill wastes have been widely investigated and demonstrated over the past decade. However, their potential utilization as biodegradable pesticides against plant pathogens is still poorly understood. In this study, a series of laboratory bioassays was designed to test the inhibitory effects of sterile water extracts of two-phase olive mill wast...
