The effects of coating the biochars with Fe(III) on adsorption of As(III) and As(V) were also studied. Batch equilibrium adsorption was employed to determine the adsorption capacity of the biochars for As(III) and (V). The adsorption data were fitted to the Langmuir adsorption model. The maximum adsorption capacity (Q max ) of both EFBB and RHB for As(III) was higher than for As(V). The Q max of EFBB and RHB for As(III) was 18.9 mg g À1 and 19.3 mg g À1 , respectively. In contrast, the Q max of EFBB and RHB for As(V) was only 5.5 mg g À1 and 7.1 mg g À1 , respectively. Coating the EFBB and RHB with Fe(III) increased their Q max values for both As(III) and As(V). The Q max of Fe-coated EFBB (FC-EFBB) and Fe-coated RHB (FC-RHB) for As(III) was 31.4 mg g À1 and 30.7 mg g À1 , respectively. The Q max of FC-EFBB and FC-RHB for As(V) was 15.2 mg g À1 and 16.0 mg g À1 , respectively. Although the surface area of the EFBB (1.890 m 2 g À1 ) was much lower than the RHB's (25.161 m 2 g À1 ), its adsorption capacity for the As was not much different than the RHB, suggesting that oxygen-containing functional groups, zeta potentials, the amounts of functional groups, O/C ratios, (O + N)/C ratios and polarity indices [(O + N)/C] were important in determining As adsorption by these biochars. The biochar surfaces were smooth before As adsorption and became coarser after As was adsorbed. The adsorption of As was confirmed by the EDS data. EFBB and RHB have potentials to be used as low cost adsorbents for removal of As(III) from waste water while FC-EFBB and FC-RH could be used for removal of both As(III) and As(V) ß

This study was conducted to describe the long-term charcoal-induced changes in organic carbon (OC) content and other soil properties of temperate deciduous forests in Mazandaran province, northern Iran. Three sites were sampled to collect composite soil samples from two depths (0-20 and 20-40 cm) inside and outside of a plot of charcoal-enriched soils surrounding a historical charcoal production site (abandoned for more than 120 years). The presence of charcoal in soils for about 120 years elevated significantly the black carbon, total OC, natural soil OC, total nitrogen, dissolved organic matter, soil OC density, exchangeable bases, saturated hydraulic conductivity, available water capacity and available Fe, Mn and Zn compared to the adjacent reference soils. Cation exchange capacity (CEC) and pH were 15.5 cmol c kg-1 and 0.5 units, respectively, higher than the adjacent reference soils at 0-20 cm soil depth. However, electrical conductivity (EC), bulk density and available Cu were higher in the adjacent reference soil. The aged charcoal had no significant effect on the microbial respiration rate of studied soils. The results of this study provide new insights and strong support for the long-term benefits of biochar application as a management strategy for improving soil productivity as well as sequestering large quantities of durable carbon in soils of the region and mitigating global warming.

However, incorporation of biochar and mixture of biochar and compost into calcareous soils is a relatively novel concept for improving soil quality and yield since calcareous soils comprise a large scale of soils worldwide. The objective of this study was to determine the effects of the co-application of biochar and compost on the soil properties, nutrient status and grain yield of rice in calcareous sandy soil. The experiment was conducted in a factorial arrangement based on randomized complete block design with three replications. The compost application rates were 1% and 3% (w/w; compost/soil) and the applied rates of biochars (rice straw biochar, RSB; sugarcane bagasse biochar, SBB) were 0.3% and 0.9% (w/w; biochar/soil). The results showed that soil pH decreased with increasing application rates of either compost or biochars. However, soil EC was enhanced through increasing the application rates of compost and biochars. The coapplication of biochar and compost improved soil total N and available P concentrations. The soil available K increased with increasing the rate of incorporated biochars and compost. An increase of soil available K was more predominate with the application of RSB than SBB. The RSB, also, added a considerable amount of silicon (Si) to the soil. The co-incorporation of biochars and compost enhanced soil available concentrations of Fe, Zn, Cu, and Mn as well. The RSB was more effective than the SBB in grain yield enhancement almost certainly due to a higher Si content in RSB. Furthermore, the concurrent application of biochars and compost increased grain yield more than applying them individually. A higher application rate of biochar and compost induced a higher grain yield. The co-application of highest rates of RSB (0.9%) and compost (3%) induced the highest grain yield (26.1 g/pot) among the treatments. The increase in yield compare to the control were 321% and 260% for 0.9% RSB + 3% compost and 0.9% SBB + 3% compost, respectively. The increase in the grain yield was due to an improvement in the soil chemical properties and nutrients enhancement. Finally, the co-application of the highest rate of RSB (0.9%) and compost (3%) is recommended to obtain the appropriate rate of rice grain yield in calcareous sandy soil.

The practice of using biochar as a low-cost adsorbent for heavy metals removal from water bodies is common. However, the effects of total acidic functional groups and particle size class on heavy metals removal by biochar are not studied well. Therefore, this study was undertaken with the objective of determining the effects of total acidic functional groups and particle size class on Cd adsorption from aqueous solution by an empty fruit bunch biochar (EFBB) and a rice husk biochar (RHB). The results showed that there was no significant difference in the carbon content between the EFBB and RHB. However, higher quantity of total acidic functional groups was found in the EFBB compared to the RHB. The total acidic functional groups of EFBB were higher than of the RHB for the same particle size class. In contrast, the surface area of RHB was higher than the EFBB for the same size class. The Langmuir's maximum adsorption capacity (Qmax) of EFBB was higher than RHB when compared at each particle size class. Significant correlations were observed between Qmax and the total acidic functional groups of both biochars. There were significant correlations between Qmax and the cation exchange capacity (CEC) as well. However, the correlations were non-significant between Qmax and particle size, surface area and pore volume of both biochars. It can be concluded that only the total acidic functional groups and the CEC were influential in determining the adsorption capacities of both EFBB and RHB for Cd adsorption.

Decomposition of plants and other organic residues in the soil and improper discharge of sewage lead to the presence of nitrates in the sources of surface and groundwater and flowing water drainage in agricultural drainage networks and their pollution. This study aimed to study the potential use of chloride layered double hydroxide (LDH) nanoplates to remove nitrate from aqueous solutions. The nano-material of chloride-LDH was made by hydrothermal technique and then, its characteristics were specified through scanning electron micrograph and removal of nitrate from aqueous solution by the minerals was investigated in terms of pH, time, speed of shaker, different concentrations of adsorbent and surface adsorption isotherm. Microscopic images of built nanoplates were examined using FESEM and SEM electron microscope with two magnifications. The thickness of nanoplates was about 20nm and their diameter was about 250 nm. Magnified image of the synthesized nanostructures shows squamous-shape. Surface adsorption isotherm of nitrate by chloride-LDH nanoplate was explained with Langmuir model shown with the values greater than 2R. In surface adsorption of nitrate, the optimal values were measured as following: pH = 7, speed = 250 rpm, time = 45 min, concentration of adsorbent = 0.1gr.

In the current study, mitigative roles of SPD and TL were assessed in Cd stressed Portulaca oleracea plants. SPD (1, 0.5, and 1 mM) was applied after 20 days of sowing on the branches and leaves of plants inoculated or without TL inoculating in the presence of Cd (0, 30, 60 and 90 mg.kg-1). Cd stress and coexistence with TL increased the activity of antioxidant enzymes and leaf soluble protein in purslane plants. Also, the application of SPD, especially at 0.5 mM, resulted in a higher increase in leaf protein under cadmium stress in inoculated plants. Proline parameter responds differently to TL. SPD application reduced the severity of these changes. The amount of H 2 O 2 was significantly reduced in plants when treated by both TL and SPD. Significant differences were observed between 0.5 and 1 mM of SPD in terms of the Cd uptake in the TL inoculated purslane shoots. Inoculated purslane plants treated by either 0.5 or 1 mM of SPD had lower Cd uptake and greater BF. In general, the results showed a synergetic effect between TL fungi and SPD application on improving the Cd phytoremediation in the purslane plant.

The lack of sufficient soil moisture and temperature data requires the characterization of the pedoclimate on the basis of climatic data processed by simulation models. This research was conducted to consider the new approach for SMR and STR mapping. The objectives of this study were to compare the four interpolation schemes including ordinary kriging (OK), cokriging (Co-K), inverse distance weighting, and conditional simulation for interpolating the monthly mean total precipitation (MMTP) and monthly mean air temperature (MMAT) and to apply the Java Newhall simulation model for the MMTP and MMAT predictive values at each node of 1 km2 grids across the Mazandaran province, northern Iran, for delineating the SMR and STR classes. The semivariogram analyses showed moderate to strong spatial dependence of data sets. The accuracy of interpolators varied within months for both MMTP and MMAT data sets. In most cases, OK and Co-K methods had the highest accuracy with lower mean error, root mean square error, and higher concordance correlation coefficient. The predictive maps show high diversity of SMR classes including Aridic, Ustic, Udic, and Xeric. The STR classes comprise Mesic, Thermic, and Cryic regimes. Results herein indicated that geostatistical approaches can potentially provide the opportunity for mapping of SMR and STR classes in data scarce regions.

The results showed that there was no significant difference between the carbon content of biochars formed from empty fruit bunches (EFBB) and rice husks (RHB). However, the EFBB did present higher quantities of O, H, S, N, and K, compared to the RHB. Although the EFBB had a much lower surface area than the RHB, the former adsorbed much more Zn, Cu, and Pb than the RHB. The higher adsorption capacity of the EFBB over the RHB was a result of the EFBB having higher amounts of oxygen-containing functional groups, a higher molar ratio of O/C, and a higher polarity index [(O + N)/C]. This suggests that the biochar's chemical properties were more important than its surface area in the adsorption of Zn, Cu, and Pb.

The effects of removing dissolved organic carbon (DOC) from the soil samples on napropamide degradation and leaching were also studied. The addition of CD and POME to BRIS soil increased the napropamide half-life values to 69 and 49.5 days, respectively. Sterilization of the soil samples resulted in partial inhibition of napropamide degradation in all soil samples. The half-lives of napropamide in BRIS soils receiving 0, 20, 100, and 200mgkg-1 of DOC derived from CD were 43, 46.2, 53.4, and 63 days, respectively. The napropamide half-lives in soil samples treated with 0, 20, 100, and 200mgkg-1 of DOC derived from POME were 43, 49.2, 57.7, and 69 days, respectively. However, in the sterilized soil samples, there were no significant effects of adding DOC derived from either CD or POME on napropamide halflives. Incorporating either CD or POME decreased napropamide leaching and total amounts of napropamide remained in the soil columns after two pore volumes of water has been leached were higher in the amended than the non-amended soil. The CD was more effective in decreasing napropamide leaching than the POME. There were no effects of DOC on napropamide leaching in all soil treatments.

Water Conservation 48 under any precipitation condition, the soil should have enough infiltrabili... more Water Conservation 48 under any precipitation condition, the soil should have enough infiltrability, permeability and capacity to store water. Water is the main constraint in dryland farming in the West of Iran. Precipitations tend to accrue during winter, while crops' growth season in spring is accompanied by high temperatures. These conditions are the constraints limiting crop production in dryland agriculture in Iran (Hemmat and Eskandari, 2004b). 1.3 Tillage The objective of tillage operations is to improve soil conditions including porosity, temperature, and soil water storage capacity for increased crop production (Alvarez and Steinbach, 2009). Tillage systems that practise conservation farming during the winter are known as important methods in controlling soil erosion and runoff (Alvarez and Steinbach, 2009; Derpsch et al., 1986). Tillage practices play an important role in dry farming agriculture; however, the appropriate implements, their time and method of use have to be specific for different agro-climatic zones. 1.3.1 Conservation tillage Conservation tillage research studies have focused on the effects of tillage practices on soil and moisture conservation for increased crop production, water conservation and soil erosion control. Several studies have attempted to develop appropriate and sustainable tillage and residue management methods that would maintain favorable soil conditions for crop growth. After harvest, stubble mulch is accumulated on the soil surface. Such materials do not only prevent direct impact of raindrops on the soil, but also impede the flow of water down the slope, thereby decrease the water flow on the soil surface and increase the amount of infiltration water (Hemmat et al., 2007). Conservation tillage systems have the potential to improve soil quality and reduce soil loss by providing protective crop residue on the soil surface and improving water conservation by decreasing evaporation losses (Su et al., 2007). Tillage creates a rough cloddy surface that lengthens the time necessary for the rain to break down the clods and seal the surface. Reduced tillage practices have been used in the production of many crops to increase soil water conservation (Locke and Bryson, 1997; Peterson et al., 1998). Reduced tillage practices protect soils from erosion and runoff by maintaining more crop residue on the soil surface. The magnitude and trends of change in soil physical properties depends on antecedent conditions, wheel tracks, soil texture and climate (Hobbs et al., 2008). However, contradictory results have been reported in literature about these effects. Mahboubi et al. (1993) showed the beneficial effects of long-term conservation tillage systems including chisel plowing and no-tillage compared to conventional tillage in ameliorating soil physical properties. Compacted soils of arid regions have low organic matter contents and are proned to crusting which may decrease infiltration, seedling emergence and plant growth (Unger and Jones, 1998). For soils that are hard setting or have a root-restricting layer, some form of mechanical loosening through deep tillage is necessary to conserve the soil and water in order to facilitate crop growth (Nitant and Singh, 1995; Vittal et al., 1983). On the other hand in some soils, water conservation and water and wind erosion contros are major goals of conservation tillage systems. Any tillage method that keeps residue on the surface may protect the soil against dispersion by rain drop impact and the pounded or flowing water will decrease crusting (Hoogmoed and Stroosnijder, 1984; Pikul Jr and Zuzel, 1994) www.intechopen.com Alternative Management Practices for Water Conservation in Dryland Farming: A Case Study in Bijar, Iran 49 1.3.2 Comparing various tillage systems Studies have revealed that tillage operations do modify soil properties including soil structure (Roger-Estrade et al.
