“…All samples become more harden for 28 days [11][12][13][14]. This is caused by the slow formation of calcium hydrated silicates (C-S-H) which resulted from the reaction of anhydrous-silicate constituents of cement with water [15] [16]. However, even the UCS of sample with SCB are not high compared to sample without SCB, the result is still exceeded the minimum landfill disposal limit stated by US EPA of 0.35 Mpa (350kPa) at 28 curing days.…”

Abstract. Disposals of agricultural waste in a large volume have an extremely harmful effect on the environment if they are ineffectively treated. To solve this, several appropriate methods has been identified to produce new recycling technique of utilizing the agricultural waste. In this study, the feasibility of using sugarcane bagasse (SCB) as partial replacement binder with cement to stabilized and solidified (S/S) the contaminated soil are investigated. This paper focused on the strength and the leaching characteristic of lead (Pb) contaminated soil treated with SCB and cement. Two tests, namely the Unconfined Compressive Strength (UCS) test and Toxicity Characteristic Leaching Procedure (TCLP) were employed to measure the strength and leaching performance of S/S samples. The experimental results demonstrated that the UCS at 28 days was in a range of 0.82 to 5.66 MPa for sample containing cement and SCB compare to 0.29 MPa of control mix at the same age. The concentration of Pb in the leachates was within the limits specified by US EPA as low as 2.11 mg/L in 28 days. This shows that, the quality of S/S sample containing cement and SCB significantly improve the strength development as well as effectively in reducing the Pb leachability. Based on the finding, SCB could be useful as cheaper, easy available alternatives binder for the treatment of contaminated soil.

Aims We aimed to develop an effective bacterial combination that can combat F. oxysporum infection in watermelon using in vitro and pot experiments. Methods and results In total, 53 strains of Bacillus and 4 strains of Pseudomonas were screened. Pseudomonas strains P3 and P4 and Bacillus strains XY-2-3, XY-13, and GJ-1-15 exhibited good antagonistic effects against F. oxysporum. P3 and P4 were identified as P. chlororaphis and P. fluorescens, respectively. XY-2-3 and GJ-1-15 were identified as B. velezensis, and XY-13 was identified as B. amyloliquefaciens. The three Bacillus strains were anti-fungal, promoted the growth of watermelon seedlings and had genes to synthesize antagonistic metabolites such as bacilysin, surfactin, yndj, fengycin, iturin, and bacillomycin D. Combinations of Bacillus and Pseudomonas strains, namely, XY-2-3+P4, GJ-1-15+P4, XY-13+P3, and XY-13+P4, exhibited a good compatibility. These four combinations exhibited antagonistic effects against 11 pathogenic fungi, including various strains of F. oxysporum, F. solani, and Rhizoctonia. Inoculation of these bacterial combinations significantly reduced the incidence of Fusarium wilt in watermelon, promoted plant growth, and improved soil nutrient availability. XY-13+P4 was the most effective combination against Fusarium wilt in watermelon with the inhibition rate of 78.17%. The number of leaves; aboveground fresh and dry weights; chlorophyll, soil total nitrogen, and soil available phosphorus content increased by 26.8%, 72.12%, 60.47%, 16.97%, 20.16%, and 16.50%, respectively, after XY-13+P4 inoculation compared with the uninoculated control. Moreover, total root length, root surface area, and root volume of watermelon seedlings were the highest after XY-13+P3 inoculation, exhibiting increases by 265.83%, 316.79%, and 390.99%, respectively, compared with the uninoculated control. Conclusions XY-13+P4 was the best bacterial combination for controlling Fusarium wilt in watermelon, promoting the growth of watermelon seedlings, and improving soil nutrient availability.
