“…Rice husk plus papaya waste encouraged the growth of earthworms compared to treatments with rice husk alone. Seferoglu et al (2012) investigated the impact of solid and liquid olive oil waste applications on soil properties. Results indicated that organic matter content and micronutrients (N, P, K, and Mg) increased slightly with applications of olive oil waste, whereas soil pH decreased with both liquid and solid forms of waste applications; undesired effects of Na in soils disappeared over the experimental period.…”

The negative environmental impacts of agricultural waste typically draw attention. However, agricultural waste has beneficial uses as an energy source, chemical recycling agent, and chemical adsorbent. This review examines the characterization, reuse, treatment, and management (minimization) of agricultural waste. Agricultural Water Pollution. Pierantozzi et al. (2012) examined physicochemical, toxicological, and genotoxicological properties of olive mill wastewater, olive wet husk, and olive brine. The results showed that olive wastes' inhibitory effects on seed germination and seedling growth, and the direct use of olive wastes for other agricultural processes should be limited because of their possible chemotoxic, phytotoxic, and antimicrobial effects.

“…Meanwhile, olive mill by-products and their compost with other plant materials have been widely used as soil amendments in agriculture, contributing significantly in circular and sustainable economy, as they lie in supporting agricultural recycling of the generated wastes [8,9]. Besides the reduction in the annual amount of olive mill point source pollution to surface water and underground aquifers, many researchers have proven that they can improve soil chemical and physical characteristics [8,[10][11][12], increase the organic matter content in non-fertile soils [10,13] and amplify nutrient absorption [14]. In addition, their application to landfills has the positive effect of reducing organic loads, and their use in horticulture may reduce and replace peat.…”

This study, based on circular economy principles and sustainable development practices, aims to present the results of soil samples analysis after their mixture with a biobed bio-mixture of straw, soil and compost, used for two consecutive years as organic bio-filter of olive oil mill wastewater. So far, exhausted bio-mixtures used in biobeds to minimize pesticide point-source contamination turned out to contain residues of pesticides, and they are considered hazardous wastes; thus, they require special treatment before their disposal. Contrariwise, saturated bio-mixtures from bio-bed systems utilized for olive mill wastewater (OMWW) treatment not only do not require any special treatment before their final disposal but also can be exploited as a soil amendment. To this end, the effects of the used bio-mixture application in three different proportions as a soil amendment on the physical and chemical properties of medium-texture soil were investigated. The application of water simulating a typical irrigation period during a growing season took place. Upon completion of the water application, soil samples were collected from two different depths of the columns and analyzed, and leachates collected from the columns were also analyzed. Soil texture, organic matter, calcium carbonate, electrical conductivity (EC), pH, total nitrogen, nitrates, nitrites, ammonium, available phosphorus, exchangeable potassium, sodium, calcium and magnesium, exchangeable sodium percentage (ESP), cation exchange capacity (CEC), available iron, manganese, copper, zinc and boron were monitored in the soil samples as indexes of potential soil amendment, and EC, pH, nitrates, potassium, sodium, calcium, magnesium, sodium adsorption ratio (SAR), total hardness, iron, manganese, copper, zinc and boron were monitored in the leachates as indexes of potential groundwater contamination.The study demonstrated the effective use of saturated bio-mixture as an organic soil amendment, while the impact of selected amendments on groundwater was the minimum.
