“…The highest amount of soil organic matter (9.06%) was observed after planting; under maize-haricotbean intercropping with closed end tied ridge and in furrow planting whereas the minimum (4.27%) were observed before planting at sole maize planting on flat bed (Table 1). This result was in line with [20] that reported the amount f soil organic matter can alter rapidly and drastically as a consequence of legumes-cereals intercropping. In addition, [21] were obtained availability of soil moisture in arid and semi arid environment improved decomposition of organic matter by 20% in comparison to low temperature areas.…”

Mono cropping is the dominant factor influencing plant nutrient uptake and loss of soil quality in Ethiopia whereas intercropping of cereal/legume has positive environmental qualities. Likewise drought and moisture stress condition is widely expanding from all direction to the center of the country. Therefore, the objective of this research was to evaluate influence of planting methods, tied ridge and cropping system on different soil chemical properties in case of Madda Walabu district, Southeast Ethiopia. It was undertaken at Bidire from March 2016 to January, 2017. In this experiment, one maize variety (Melkassa 2) and one haricot bean variety (Nasir) were used. Treatments include open end and closed end tied ridge; sole cropping and intercropping; and in furrow, on ridge and flat bed planting. Each treatment has been triplicate and the experiment plots were laid out in randomized complete block design. Intercropping of maize-haricot bean with tied ridge and planting methods were highly influenced soil pH, exchangeable potassium, available phosphorous, soil organic matter and total soil nitrogen. Generally, the use of intercropping and closed end tied ridge in combination with in furrow planting significantly increased (p 0.05 ) soil fertility in the system, which could be promising for sustainable improvement of crop production and productivity for semi arid areas of Bale zone.

“…Oil palm shell has been successfully used to produce high quality activated carbon because of their inherent high densities and carbon content (Normah et al 1995;Hussein et al 1996;Guo and Lua, 2000). In this work char from oil palm shell was prepared according to the method described by Guo and Lua, 2000.…”

This research focuses on understanding biosorption process and developing a cost effective technology for treatment of heavy metals-contaminated industrial wastewater. A new composite biosorbent has been prepared by coating chitosan onto acid treated oil palm shell charcoal (AOPSC). Chitosan loading on the AOPSC support is about 21% by weight. The shape of the adsorbent is nearly spherical with particle diameter ranging 100~150 µm. The adsorption capacity of the composite biosorbent was evaluated by measuring the extent of adsorption of chromium metal ions from water under equilibrium conditions at 25ºC. Using Langmuir isotherm model, the equilibrium data yielded the following ultimate capacity values for the coated biosorbent on a per gram basis of chitosan: 154 mg Cr/g. Bioconversion of Cr (VI) to Cr (III) by chitosan was also observed and had been shown previously in other studies using plant tissues and mineral surfaces. After the biosorbent was saturated with the metal ions, the adsorbent was regenerated with 0.1 M sodium hydroxide. Maximum desorption of the metal takes place within 5 bed volumes while complete desorption occurs within 10 bed volumes. Details of preparation of the biosorbent, characterization, and adsorption studies are presented. Dominant sorption mechanisms are ionic interactions and complexation.

Magnetic activated carbon (MG-AC), a solid product made by dispersing magnetic substrates on AC, is gaining attention for the removal of heavy metals from wastewater due to its favorable physico-chemical properties such as enhanced surface area and magnetic properties, respectively. However, the effects of two contrasting substrates, i.e., metal solution and metal particles, for the synthesis of MG-AC to obtain enhanced magnetic property have not been considered. The MG-AC was prepared by incorporating Fe 3 O 4 into the AC from two different sources of iron: Fe 3 O 4 extracted from electric arc furnace slag and from a ferric chloride/ferrous sulfate solution, to produce magnetic palm kernel shell from slag (MG-PKSS) and magnetic palm kernel shell from iron suspension (MG-PKSF), respectively. The adsorbent samples were characterized using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis, X-ray diffraction, electron microscopy, i.e., SEM and FESEM, energy-dispersive X-ray, nitrogen adsorption, vibrating sample magnetometer. The results showed that the MG-PKSF had a greater BET surface area of 257 m 2 g -1 , a pore volume of 0.1124 cc g -1 and higher magnetic properties with a magnetic saturation of 49.55 emu g -1 relative to the MG-PKSS. The FTIR spectrum of the MG-PKSF illustrated the intense OH bending at 1629 cm -1 which can be attributed to the presence of oxygen in the samples. The absorption bands at 1093 and 579 cm -1 indicated the presence of C-O stretching and metal-oxygen (M-O) bands due to the interaction of iron and oxygen. Therefore, the MG-PKSF presented better characteristics for heavy metal removal from wastewater relative to the MG-PKSS, thereby suggesting that the raw material (metal solution) for impregnation played a crucial role in enhancing the quality of the MG-AC.
