On organic matter contents (A), on electrical conductivity of soil extract, 1:5 (soil/H2O) (B), on soil pH (C), on nitrogen contents (D), on P form contents (E), on exchangeable K contents (F), on exchangeable Na contents (G), on Cu forms (H), on Zn forms (I), and on Mn forms (J). The toxicity is evident in all the plant functions from the germination to organs morphology, physiology, metabolism, ultrastructure, ripening and quality of the final product. Germination of Barley and Tomato seeds was investigated on a medium formulated from industrial waste by-product. The large, relatively stable sand-particle size increases soil aeration, improves drainage in tight soils and creates plant-growth s… crops, constitutes a very important solution for environment protection. Therefore, OMW field spreading may represent a low cost contribution to crop fertilization and soil amendment. 25-50% - Slightly moist, this sandy loam still forms a weak ball but when you press on it, you can see defined finger marks. It cannot be rolled to make a sausage shape. The air dried foliar tissues, incorporated at five different rates (0, 0.2, 0.4, 0.6 and 0.8 g per 50 g of soil mixture with 10.75 g of manure) resulted increase in organic carbon mineralization and nitrate nitrogen. tect whether the soil feels rough or coarse, in which case it is probably a sandy soil, or whether it feels smooth which is the feel of a clayey soil. In greenhouse cultivation with spinach and endive, the effectiveness of The results of this work demonstrated the high potential of olive mill waste, solid or liquid form, added to sandy loam soil in an incubation experiment in vitro. Throughout the last 3 decades, many studies were made, aiming to assess the impact of OMW spreading on the bare soil fertility (Paredes et al. Chemical characteristics and biodegradability of the labile organic matter, which is mainly derived, Earthworms can be used as bioindicators of soil management as they are easy to classify and very sensitive to changes of both physical and chemical soil parameters. C, control (soil); 24.39 g of solid waste + 8.13 g of olive mill wastewater (3:1 (S/L)), 20.4 g of solid waste + 20.4 g of olive mill wastewater (1:1 (S/L)), and 13.7 g of solid waste + 41.1 g of olive mill wastewater (1:3 (S/L)) were added correspondingly to 50 g of the same soil. Moreover, the soil amended with the solid (S) form of olive mill waste reduced bacterial growth significantly, and both waste forms act negative impacts to soil-borne fungi belonging to the genus Rhizopus. Water-Holding Capacity. The availability of variety of biomass and their metal binding potential makes it a economical and sustainable option for developing effluent treatment process for removal and recovery of heavy metals. Utilization of Mill Effluent for Growth, Availability and Uptake of Nutrients by Palm Oil Seedlings Soil tillage and fertilisation did not have any significant impact on other parameters of soil structure such as dry sieving mean weight diameters (MWD), mean weight diameter of water-stable aggregates (MWDWSA), vulnerability coefficient (Kv), stability index of water-stable aggregates (Sw), index of crusting (Ic), contents of water-stable macro- (WSAma) and micro-aggregates (WSAmi). It is most extensively used construction material. undisturbed cores from two soil series (39 sandy loam and jug darkened to retard algal growth. ), phosphate. Triclosan had the highest values of K f (231 in the sandy loam and 344 in the silt loam) and K d (256 in the sandy loam and 282 in the silt loam). Terbuthylazine was applied to both plots at a rate of 2 kg ha(- 1) a.i. about 2.5 times that in the control. soil, is an efficient amendment for greenhouse soil with vegetable crops; at Isotherms confirmed adsorption by natural soil (> 2.5 mg C g−1). soil moisture in VWC by percentage using lab calibration method. Biosorption of metal ions was inhibited at pH 3.0, and sharply increased when the pH of the solution was increased to 4.0. Furthermore, the recycling of that organic waste on Before lab calibration soil properties ware analyzed in which we find out that soil was having 6.9 pH, Sandy loam Soil texture and 1.22 dry bulk density. Clay soil feels slippery when wet and you can form a tight hard ball with it. The obtained data showed that mineralization of soil organic carbon increased by 16.2–35.9% at all rates of algae addition compared to the control, while the highest increase was observed at the highest rates of algae addition. 2011; Arienzo et al. (A) Soil organic matter; (B) soil humic and fulvic acids; (C) water extract electrical conductivity; (D) soil pH; (E) soil mineral forms of N, ammonium, and nitrate; (F) organic and available P; (G) available K; and (H) exchangeable Na. Effect of olive oil mill waste on the number of bacterial colonies and fungi. Consequently, OMW spreading can be an alternative for a low cost soil organic amendment. The results show that OMCdecreased substrate pH in proportion to the OMC supplementation rate and increasedEC only at the end of the study and only in the plots with the highest supplementation rate(S:OMCH). The OMC rate of 50% v/v resulted in a minor reduction in plantvisual quality during the cold periods but in a slight improvement during the warmperiods. 2011). Effect of solid waste or olive mill wastewater added to soil on total and available forms. In this study the potential of the fungus Aspergillus niger to remove lead, cadmium, copper and nickel ions was evaluated. Obtained results show that under the conditions of our experiment, applying of this organic effluent has changed significantly the content of exchangeable potassium, mineral nitrogen, phosphorus and organic matter in soil. Water with different SAR and salinity levels was used for the infiltration study. For example, in Australia, it can be grown successfully on soils with pH ranging from 4.5 to 9.0 (measured in a 1:5 soil … Higher amounts of terbuthylazine were detected at each sampling depth in plots treated with alperujo. Unilateral compression at 200 kPa resulted in a bulk density of 1.72 Mg m- 3 at a soil moisture of 0.131 g g-' (equivalent to a matric potential of — 10 kPa) and a bulk density of 1.65 Mg m- 3 at a soil moisture of 0.058 g g-' (equivalent to a matric potential of —100 … The soil was found to be alkaline on testing (pH 8.25) and had soil EC 0.37 dS m-1. H‰„“[oœ0…ÿÊ. Itwas concluded that, when speedy establishment is imperative (such as in sod farms) orwhen irrigation is limited, an OMC rate of 50% by volume should be selected. low levels, with values ranging from 0.25 to 0.64 dSm-1 (water extract, 1 The purpose of experiment was to develop sustainable method of new agriculture practices and to reduce the negative impact of serious pollutants produced from olive mill industry and stone factories in Palestine. rate of 17920 kg of alperujo ha(- 1). Furthermore, olive OMW decreased fungi spores' number on infested fruits-vegetables and acted positively on tomato plants fresh weights, infested with the soil borne pathogen F. oxysporum f.sp. The pretreated A. niger biomass could be used for five cycles of biosorption – elution of biosorbed ion – regeneration of biomass. According to the obtained results we can confirm that OMW can be very useful as an organic amendment in agriculture. The results proved the effect of the algae Chlorella vulgaris as an accelerator agent in biodegradation of soil organic matter, without any significant negative impact on soil chemical properties. Obtained results show that under the conditions of our experiment, applying of this organic effluent has changed significantly the content of exchangeable potassium (197% and 221%, respectively, for Dar Dhaoui (A) and El Fje (B) soil), mineral nitrogen, phosphorus (370% and 445%, respectively for (A) and (B) soil), and organic matter in soil (from 0.92% to 1.51% and from 0.87% to 1.95%, respectively, for (A) and (B) soil). 3-16) are sand, loamy sands, sandy loams, loam, silt loam, silt, Sandy loam soils are broken down into four categories, including coarse sandy loam, fine sandy loam, sandy loam and very fine sandy loam. Olive-oil production is of vital importance for the economy and social life of the Mediterranean region; however, the side effect of the olive-oil mill activity is the generation of enormous quantities of biotoxic olive-mill waste within a short period of three months. Therefore, an SESC plan for a site with a soil that has significant amounts of silt and clay should be heavily reliant on soil erosion measures rather than sediment control. Many olive mills are scattered in most Mediterranean countries which produce it seasonally. used mixture correspond to 21 tons of water soluble waste and 7 tons of The coir is a natural fibrous material and during its use as substrate in soilless cultures, is partially disintegrated, consisted by 56% of organic matter, and contain nutrient elements. International Journal of Recycling of Organic Waste in Agriculture, Technological Educational Institute of Thessaly. OMW application did not cause a significant change in soil pH, due to the low quantity of OMW used in the soil. This research showed that fungal biosorption had a potential to be used in the removal of heavy metal ions from wastewaters. The experiment was replicated three times. solid waste per hectare, or 17.34 kg of N, 22.63 kg of P2O5 and 98.7 kg of For the Acrudoxes, in which the clay fraction was less dispersed in water, 2,4-D retention was higher in larger aggregates (> 53 mu m), having higher total organic C (OC) content and higher degree of humification of its organic matter (OM). Numerous physicochemical and biological methods have been used in the past for the treatment of both olive mill wastewater (OMWW, deriving from three-phase extraction systems) and two-phase olive mill waste (TPOMW, deriving from two-phase extraction systems), but these generally failed to come up with a viable solution of wide applicability. Ic was correlated with organic matter content in all combinations of treatments. In MT, contents of Ca2+, Mg2+ and Na+ were significantly correlated with contents of WSAmi and WSAma. The labile organic matter of sludge extracts appeared less humified than that of manure-treated and control soils. It is a well-draining, porous soil, and water flows right through it, avoiding soggy soil. In greenhouse cultivation with spinach and endive, the effectiveness of implementation of mixture of solid and water soluble olive oil mill waste, in replacement of mineral base dressing, was tested. Incontrast, for sustainable bermudagrass growth, a rate of 12.5% by volume is preferred,because it increases the visual quality of the grass and root growth. It consists of particles of rock and hard minerals, such as silicon dioxide. The amendment of cultivated soils with suitable organic materials, affects its chemical and physical properties (Koyama et al., 2009;Herath et al., 2013;Jayasinghe et al., 2014). Initially, the soil was low in organic carbon (0.31%) and available nitrogen (110 kg ha-1); and medium in available phosphorus (16.1 kg ha-1) and available potassium (290 kg ha-1). Consequently, OMW is considered as a rich organic material and may constitute a potential potassic amendment for dryland soils poor in this element, which has the tendency to increase the content of major elements and the soil organic matters. Twenty-fourplots (1.44 × 1.44 m) were filled with sandy-loam soil and supplemented with one of threeOMC proportions (low= 12.5%, medium = 25%, and high = 50% by volume, indicatedas substrates S:OMCL, S:OMCM, and S:OMCH, respectively), and non-amended soilserved as a control (S). In contrast, the proportion of labile organic matter was significantly lower in sludge-treated soils than in manure-treated and control soils. The results showed that plant height, stem diameter and number of fronds of palm oil seedlings at 26 weeks after planting (WAP) were significantly affected by application of 9.6 L mill effluent with 50%-75% NPKMg. Management of arable soils plays a significant role in forming and maintaining their structure. This is due to the low quantity of OMW used in the soil. iv. Chemical and biological properties of a sandy loam soil amended with olive mill waste, solid or liquid form, in vitro August 2013 International Journal of Recycling of Organic Waste in Agriculture We recommend some caution about the type and quality of organic matter added to increase organic carbon in soil. Addition of crop residues and NPK fertilisers significantly increased St values (by 7%) in comparison with NPK-only treatments. The antifungal activity of olive oil mill wastewater (olive OMW) was investigated.

(2011) measured the infiltration rate using a double-ring infiltrometer. Decreasing mV in the zeta potential, ζ, curves and electron-donor component, γ–, when adding HA to natural surfaces showed effective HA adsorption, but only when soil organic matter had not been removed previously. Between them, the plant debris for their role in the soil fertility, the plant essential oils for their role as pesticides against soil-borne pathogens (Gravanis et al. 1939). The data revealed significantly greater values of earthworm species richness, density, soil organic matter, and moisture in the organic olive groves than in the conventional ones. A. niger biomass pretreated by boiling in 0.1N NaOH solution for 15 min exhibited higher lead, cadmium and copper removal capacities than did live biomass. MT resulted in an increase of critical soil organic matter content (St) by 7% in comparison with CT. The effects of addition of this residue on soil biological and chemical properties were studied by two ways, firstly with an incubation experiment of 15 weeks and secondly by a greenhouse tomato crop. It will not leave water staining on your fingers and … 1992; Cabrera et al. This is probably due to the fact that the OML is acidic in nature, and the SSW is basic in nature. The detoxification and biotransformation potential of naturally occurring and other microorganisms is a promising alternative to the previous approach, especially in cases where in situ decomposition of such waste can not be readily applied. Total interaction energy was determined from the zeta potential (ζ) and surface free energy, measured under different experimental conditions [natural and, Our aim was to establish the long-term effects of repeated applications after 20 y of organic amendments (farmyard manure at 10 t ha−1 y−1, and urban sewage sludge at two different rates, 10 t ha−1 y−1 and 100 t ha−1 every 2 y) on the quality of a sandy and poorly buffered soil (Fluvisol, pH 6). lycopersici. The levels of available forms of K, Cu, Mn and Fe were increased at the two higher rates of added leaves, while the levels of available forms of P, Zn, ammonium nitrogen and exchangeable Na did not show statistically significant differences in comparison with the control at the end of the incubation period. To alleviate the environmental pollution, it is necessary to reduce the problem by using it as a liquid organic fertilizer. Join ResearchGate to find the people and research you need to help your work. Higher contents of Na+ negatively affected St values and positive correlations were detected between Ca2+, Mg2+ and Na+ and Ic in NPK treatments. The DTPA - extractable … In addition to the increase in humic substances and the improvement of germination indices, the parameters studied confirm the stability and the maturity of the composts. Soil texture Sand 1-5 Fine Sandy loam 5-10 Loam 5-15 Clay Loam 15-30 Clay >30 AGRONOMY Soil Cation Exchange Capacity (CEC) Effect of pH on Soil CEC In addition to clay and organic matter, pH also has an effect on CEC. Olive mill wastewater (OMW) is the main residual product of olive processing and its disposal can represent a relevant environmental issue in Mediterranean countries, where olive oil production is large and concentrated in a short-lasting period. The log K oc values for the PPCPs tested varied from 1.85 to 4.30. However, even with the prospect of the contamination risk of water and/or soil following OMW spreading, the consideration of the OMW as fertilizer is promoted through its beneficial compositions, such as N, P, K, Mg and Fe and organic carbon (Bonari et al. Thus, the influence of soil water content on retention and mineralization of the herbicide 2,4-D [(2,4-dichlorophenoxy)acetic acid], as well as its distribution on the aggregate fractions (diameter > 150, 53 to 150, 20 to 53, 2 to 20, and < 2 mu m) were evaluated. Soil and climate: Red sandy loam soils with good drainage are ideal for good leaf yield. the end of the growing period, soil salinity was maintained at low levels, As well as assessment of its effect on pH, salinity of soils in arid regions. Profile 0 to 3 inches; grey-brown sandy clay loam; sharp junction with: In 2004, the clipping yields were unaffectedby OMC rate. effective on sandy soils, moderately effective on loam soils, and have little effectiveness on silt and clay soils. The amounts of sand, silt, clay and organic matter in a particular soil play a large part in the way that it behaves, how it can be man-aged and what it can be used to grow. All rights reserved. Triplicates from each plot were sampled at 3 depths (0-10, 10-20 and 20-30 cm), air-dried, remains of olive leaves, grass roots, and stones removed and sieved through a 5 mm mesh sieve. The soil electrical conductivity during the cultivation was maintained at relatively low levels, with values ranging from 0.25 to 0.64 dSm-1 (water extract, 1 soil: 5H 2 O).
