chemical properties and biological activity in soils of mallorca following twenty years of treated Wastewater Irrigation
Journal of Environmental Management, 2012Co-Authors: Maria Adrover, Edelweiss Farrus, G Moya, Jaume VadellAbstract:On the Mediterranean island of Mallorca, the use of secondary-treated municipal Wastewater in Irrigation was introduced with the construction of the first Wastewater treatment plants in the 1970s. In this study, the chemical properties and biological activity of 21 arable soils, irrigated for more than 20 years with secondary-treated Wastewater, were tested in order to assess their quality. Soil quality was evaluated by measuring cation exchange capacity, pH, calcium carbonate equivalent, soil organic matter, total nitrogen, available phosphorus, water-soluble organic carbon, soil microbial biomass, soil basal respiration, and the activities of the enzymes dehydrogenase, β-glucosidase and alkaline phosphatase. No negative effects of the Irrigation treatment were observed on the measured soil parameters. Indeed, soil water-soluble organic carbon, soil microbial biomass and β-glucosidase and alkaline phosphatase activities increased under treated Wastewater Irrigation. Biological activity of soils irrigated with treated Wastewater was affected mainly by soil organic matter content. Although the typical crop management of alfalfa, and other forage crops associated with treated Wastewater Irrigation, may have contributed to the increase of these parameters, the results suggest that Irrigation with treated Wastewater is a strategy with many benefits to agricultural land management.

impact of Wastewater Irrigation on soil physico chemical properties growth and water use pattern of two indigenous vegetables in southwest nigeria
Catena, 2016Co-Authors: T P Abegunrin, D O Idowu, M A AdejumobiAbstract:Abstract The indiscriminate use of Wastewater for Irrigation as a result of freshwater shortage could impair soil functions and cause environmental pollution. The objective of this study was to evaluate soil physico-chemical properties, growth parameters and water use pattern of two indigenous vegetables irrigated with three kinds of Wastewater in southwest Nigeria. The study was a 2 × 4 factorial (Wastewater versus vegetable) pot experiment, laid out in randomized complete block design (RBCD) with three replications in a screen house. The tested vegetables were SM — Eggplant (Solanum macrocarpon) and CA — Spinach (Celosia angentea) while the Wastewater treatments were abattoir Wastewater (AW), bathroom, laundry Wastewater (BW) cassava effluent (CE) and rainwater (RW) as control. The Wastewaters were analyzed for physical, chemical and biological properties while the soil samples collected from the field at 0–20 cm soil layer and pots at 0–10 and 10–20 cm layer were analyzed for physico-chemical properties before and after the experiment, respectively. Soil hydrophobicity was determined using the water-droplet penetration time (WDPT) method, plant growth parameters were monitored every 5 days while leaf area was determined shortly before harvest. Consumptive water use was determined using the soil water balance technique. The Wastewaters had moderate to very high degree of restriction for use in relation to salinity and sodicity. Except for CE treatment, Wastewater Irrigation increased the soil pH, Mg, K, Ca, TOC, TN and CEC at harvest. SAR surpassed the threshold value of 6 in the surface layer of CA soil irrigated with BW Wastewater. Wastewater Irrigation caused the occurrence of soil hydrophobicity, with the highest hydrophobic degree from CE treatment. The plant growth indices showed that the SM vegetable performed better under AW treatment while the CA vegetable performed better under BW treatment compared with RW treatment. The vegetables differed in relation to water use and there was no discernible trend among the different Wastewater treatments as regards the temporal distribution of the consumptive water use. The CE Wastewater had the most negative impact on both soil function and plant growth. The study showed that Wastewater resources are valuable because of improvement of soil fertility and enhanced crop growth compared with rainwater, however they need to be managed with caution, preferably treatment, before reused in relation to soil functions and crop quality.

red cabbage yield heavy metal content water use and soil chemical characteristics under Wastewater Irrigation
Environmental Science and Pollution Research, 2016Co-Authors: Talip Tunc, Ustun SahinAbstract:The objective of this 2-year field study was to evaluate the effects of drip Irrigation with urban Wastewaters reclaimed using primary (filtration) and secondary (filtration and aeration) processes on red cabbage growth and fresh yield, heavy metal content, water use and efficiency and soil chemical properties. Filtered Wastewater (WW1), filtered and aerated Wastewater (WW2), freshwater and filtered Wastewater mix (1:1 by volume) (WW3) and freshwater (FW) were investigated as Irrigation water treatments. Crop evapotranspiration decreased significantly, while water use efficiency increased under Wastewater treatments compared to FW. WW1 treatment had the lowest value (474.2 mm), while FW treatments had the highest value (556.7 mm). The highest water use efficiency was found in the WW1 treatment as 8.41 kg m−3, and there was a twofold increase with regard to the FW. Wastewater Irrigation increased soil fertility and therefore red cabbage yield. WW2 treatment produced the highest total fresh yield (40.02 Mg ha−1). However, Wastewater Irrigation increased the heavy metal content in crops and soil. Cd content in red cabbage heads was above the safe limit, and WW1 treatment had the highest value (0.168 mg kg−1). WW3 treatment among Wastewater treatments is less risky in terms of soil and crop heavy metal pollution and faecal coliform contamination. Therefore, WW3 Wastewater Irrigation for red cabbage could be recommended for higher yield and water efficiency with regard to freshwater Irrigation.

effects of untreated and treated Wastewater Irrigation on some chemical properties of cauliflower brassica olerecea l var botrytis and red cabbage brassica olerecea l var rubra grown on calcareous soil in turkey
Agricultural Water Management, 2008Co-Authors: Fatih M Kiziloglu, Ustun Sahin, Metin Turan, Yasemin Kuslu, Atilla DursunAbstract:The use of Wastewater for Irrigation is increasingly being considered as a technical solution to minimize soil degradation and to restore nutrient content of soils. The aims of this study were to test if Wastewater Irrigation could improve soil fertility without affecting the quality of soils and plants. A field experiment was conducted in 2006 to investigate the effects of Irrigation with untreated, and preliminary and primary treated Wastewater on macro- and micronutrient distribution within the soil profile, yield and mineral content of cauliflower and red cabbage plants grown on a calcareous Aridisol in eastern Anatolia, Erzurum province, Turkey. Wastewater Irrigation affected significantly soil chemical properties in the 0-30 cm soil layer and plant nutrient content after harvest. Application of Wastewater increased soil salinity, organic matter, exchangeable Na, K, Ca, Mg, plant available phosphorus and microelements, and decreased soil pH. Wastewater Irrigation treatments also increased the yield as well as N, P, K, Ca, Mg, Na, Fe, Mn, Zn, Cu, Pb, Ni and Cd contents of cauliflower and red cabbage plants. The highest yield, macro- and micronutrient uptake of cauliflower and red cabbage plants were obtained with the untreated Wastewater. Undesirable side effects such as heavy metal contamination in soil and plant, and salinity were not observed with the application of Wastewater. It can be concluded that untreated Wastewater can be used confidently, in the short term, in agricultural land, while primary treated Wastewater can be used in sustainable agriculture in the long term.

effects of Wastewater Irrigation on soil and cabbage plant brassica olerecea var capitate cv yalova 1 chemical properties
Journal of Plant Nutrition and Soil Science, 2007Co-Authors: Fatih M Kiziloglu, Ustun Sahin, Metin Turan, Ilker Angin, Omer Anapali, Mustafa OkurogluAbstract:The use of Wastewater for Irrigation is increasingly being considered as a technical solution to minimize soil degradation and to restore nutrient contents of soils. The aim of this study is to increase fertility and minimize degradation of soils irrigated with Wastewater exposed to different purification treatments. A field experiment was conducted to investigate the effects of control and Irrigation with Wastewater, which had undergone different purification treatments, on macro- and micronutrient distribution within the soil profile and nutrient contents of cabbage (Brassica olerecea var. Capitate cv. Yalova-1) in Erzurum, Turkey. Wastewater Irrigation and preliminary treatment–Wastewater Irrigation significantly affected soil chemical properties especially at 0–30 cm soil depth and plant nutrient contents after one year. Application of Wastewater increased soil salinity, organic matter, exchangeable Na, K, Ca, Mg, plant-available P, and micro-elements and decreased soil pH. Wastewater increased also yield and N, P, K, Fe, Mn, Zn, Cu, B, and Mo contents of cabbage plants. Undesirable side effects were not observed in plant heavy-metal contents, due to salinity and toxic concentrations of metals from the application of Wastewater to soil.
