Journal of Applied Sciences , 2009,
Abstract: The present study was conducted in two field experiments with two soil types (sandy and calcareous soils) under greenhouse conditions at the Agricultural and Veterinary Training and Research Station of KFU, Al-Hassa area. The objective of the present study was to investigate the effects of different rates of sludge on some soil properties, growth, yield and nutrients status of leaves and fruits of cucumber plant. The experimental soils have sandy and sandy loam textures. All experimental plots (6 m2 area) cultivated with cucumber. Soil application of sewage sludge, at rates of 0 (control, with no sewage sludge), 25, 50, 75, 100 and 125 t ha-1 was used in the present study. Sewage sludge was mixed with top 30 cm surface layer of each plot, two month before planting of cucumber. The experiments were conducted in a randomized complete block design with 3 replications. The experimental plots received the same agricultural practices as recommended. The obtained results revealed that application of sewage sludge significantly altered the chemical properties of soil. Soil Electrical Conductivity (EC), soluble cations (calcium, magnesium, sodium and potassium), soluble anions (chloride and sulphate), available phosphorous and micronutrients (iron, manganese, copper and zinc) and heavy metals (cadmium, cobalt, lead and nickel) were increased in sandy and calcareous soils with increasing sewage sludge application rate. While, the soil reaction (pH) and HCO3ˉ contents were decreased as a result of sludge application. Also, application of sewage sludge improved physical properties of sandy and calcareous soils. It decreased the soil bulk density and increased saturation water content, porosity and organic matter content. Application of sewage sludge improved leaves and fruit contents of macro- and microelements of cucumber plant grown in sandy and calcareous soils. Also, the number of fruits and yield of cucumber were increased with increasing the rates of sewage sludge application. The highest level of application of sludge has a highest effect on the yield of cucumber plants. Generally, application of sewage sludge by mixing it with top 30 cm soil layer was found to be more effective in improving soil physical, chemical and fertility conditions. Moreover, using of sewage sludge as organic manure is considered as a source of nutrients that required for plant which led to increase the growth and the yield of cucumber crop.

Abstract: The use of sewage sludge as an organic fertiliser under South African conditions is an alternative disposal route to sacrificial land disposal. However, the lack of research done under South African conditions and the conservative nature of the heavy metal guidelines, when interpreted as total metal content is limiting the agricultural use of sludge. A glasshouse experiment, which forms part of a greater project, was conducted to characterise soil-plant interactions of the main sludge-borne heavy metals (Pb, Cd, Zn and Cu) in two sludges (low metal and high metal) to different soil types (clayey, loamy and sandy) on maize seedlings. Growth differences, heavy metal accumulation in plant parts and soil-metal concentrations (total and potentially available) were determined. The low metal sludge treatment showed the highest yield for maize seedlings when compared to controls (soil unamended and inorganic fertiliser added). The amendment of sludge to the soil did indicate higher heavy metal content, although the increase was not as predicted, owing to the difficulty of obtaining a representative sample in the soil. Except for Cd, heavy metal values in the soils (at the beginning and end of experiment) exceeded guidelines due to very high background values in the soil. No negative effects of heavy metal contamination in plant parts of the crops could be proven. Results showed that application of sludge to different soils could be useful in order to increase crop growth over a 28 d period in the glasshouse. Soil, plant and water quality monitoring, together with the prevention of metals entering the plant, is a prerequisite in order to prevent potential health hazards of sludge application to agricultural land.

Abstract: Effect of sewage sludge on germination, growth and biomass yield of sorghum crop was studied utilizing three calcareous soils and the sewage sludge at the rate of 0, 25, 50 and 75 Mg ha -1 in a pot experiment. The mean crop germination ranged between 77.5-97.5 per cent and there was no significant reduction in germination due to sewage sludge application. Mean plant height ranged between 33.98-77.60 cm and the mean biomass ranged between 0.075-0.525 kg per pot in different sewage sludge treatments. The plant height and the biomass yield increased significantly with an increase in sewage sludge application. There was an increasing trend in plant height and total biomass yield in heavy textured soil than other soils. There was no significant effect of varying CaCO3 contents of soils on crop germination, plant height and biomass yield receiving different rates of sewage sludge. In conclusion, there exists an excellent potential for the use of sewage sludge not only as organic matter but also a promising source of plant nutrition for increasing the productivity of sandy calcareous soils in an arid environment. The research findings also highlighted the usefulness of sewage sludge and sewage waste for its utilization as organic matter for reasonable forage production as well as to minimize the expected environmental hazards from land disposal of these sewage wastes.

Abstract: Investigations conducted at the Podu-Iloaiei Agricultural Research Station, Ia i County, have studied the influence of different sewage sludge rates on yield quality and quantity and soil agrochemical characteristics. Trials were set up in a five year-crop rotation, winter rape-wheat-maize-sunflower-wheat. Sewage sludge was applied every 2 years at rates of 20, 30, 40 and 60 t/ha, with different mineral fertilizer rates, differentiated according to the growing plant. The Cambic Chernozem used for experiments had a clayey-loam texture (410 g clay, 310 g loam and 280 g sand), a weakly acid reaction and a mean supply with mobile phosphorus and a very good one with mobile potassium. Applying rates of 30 t/ha sewage sludge has resulted in the accumulation of mobile phosphate stock in soil of 57 mg/kg and the microelement content, mobile forms from soil, was of 7.9 mg/kg at Cu, 1.4 mg/kg at B, 6.8 mg/kg at Zn and 186 mg/kg at manganese. The combined use of mean rates of mineral fertilizers (N100P80), together with 40 t/ha sewage sludge has resulted in improving soil chemical characteristics and getting yield increases in winter rape of 1854 kg/ha (108 %). After 8 years since the application of a rate of 30 t/ha sewage sludge, soil pH has increased 0.4 units, while phosphorus and potassium content from soil has increased by 30 and 52 mg/ kg soil, respectively. Sewage sludge from the Ia i Water Treatment Station, which was applied every two years at rates of 20 and 30 t/ha, has determined the increase in the organic carbon content from soil by 2.9 g/kg (18%) and 4.4 g/kg (28%), respectively, compared to the unfertilized variant. The copper and zinc content from grains in wheat and maize crops, fertilized with 30 t/ha sewage sludge, was by two-four times higher, compared to the unfertilized control.

Abstract: The management and application of organic wastes in agricultural lands decreases environmental risks and increases utilization of these matters. The objective of this research was to investigate and compare the effect of polyacryl factory sewage sludge (PSS), municipal compost (MC) and cow manure (CM) on soil properties and on yield and growth of maize (single cross 704, Zea mays L.). The treatments were control (without any organic waste) and application of PSS, MC, and CM at two rates (15 and 45 t ha-1). This research was done in the research farm of Isfahan University of Technology (Lavark-Najafabad). The experimental design was a randomized, complete block with three replications. Treatments were incorporated into the soil before the maize planting (on 23 June 2008) and soil sampling was performed after 132 days (Simultaneously with maize harvesting). Application of the organic wastes resulted in significant increase soil organic matter (SOM), total nitrogen (TN) and saturated hydraulic conductivity (Ks) and significantly decreased bulk density. However, saturated hydraulic conductivity was decreased by application of PSS. Application of 15 and 45 t ha-1 of PSS reduced Ks more than 14% and 42%, respectively, compared with control; however, the reduction was significant only in the plots which received 45 t ha-1 of PSS compared with control. The results of plant yield and growth showed that leaf area index (LAI), plant length, biological yield, 1000 seed weight and seed yield increase due to the application of organic wastes.

Abstract: The Co-Compostage (CC) of Palm (Poenix dactylifera L.) Fiber (PF) and Sewage Sludge (SS) at volume rate (1PF/1SS), mixed with Top Soil (TS) have been used as a substrate for cucumber cultivated in soilless crop system. Five substrates with volume ratio T (CC-TS) were tested: T (10-0), T (9-1), T (8-2), T (7-3) and T (6-4). They were compared to peat in nursery and to TS in Cucumis sativus L. crop production. Total porosity, bulk density, moisture content, rate of drainage, pH and electritical conductivity of T (8-2) and T (7-3) were relatively favorable for plant growth. After 45 days of growth and in comparison to peat, T (9-1), T (8-2) and T (7-3) gave the best parameters of root development: volume, architecture, length, number, best seedling growth and a positive correlation (R = 0.751) between root and shoot dry matter. After 120 days, cucumber attained the best root development under T (8-2) and T (7-3). Fruits production of these substrates was 40% higher than those of the control.

Abstract: A pot experiment was carried out to compare the effects of sewage sludge (S) and town refuse(T) additions on plant growth and yield components of wheat (Triticum sativa L.), some soil physico - chemical properties and available nutrients in reclaiming sandy soil. The organic residues were applied at rates of 5%, 10%, and in different combinations with N, P, K mineral fertilizers. The addition of sewage sludge, town refuse and their interactions at low rates produced the striking changes in sandy soil. An improvement in soil physical and chemical properties was noticed with increasing addition of organic residues. Town refuse furnished better results than the sewage sludge. A significant increase in grain and straw yield of wheat and plant N, P, K content was found in organic residues treated soils as compared with the control. The treatment of T+NPK was better than the other treatments. A significant decrease in soil bulk density and increase in soil porosity and available NPK contents in soil was observed with organic residues as compared to the control. The investigation exhibited that town refuses were more affective than sewage sludge at different rates. The sewage sludge and town refuse can be used as soil conditioners to improve the soil health and hence the crop yield. At the same time this would help to reduce the environmental contamination.
