Evaluation of organic carbon and microbial inoculum for bioremediation of acid mine drainage

Acid mine drainage (AMD) from abandoned mines cause environmental harm and requires cost-effective, passive remediation techniques. Mining activities expose mineral surfaces to oxidation, which accelerates the release and mobilization of acidity, sulfate, and metal ions in AMD. Sulfate-reducing bioreactors (SRBRs) are an attractive means to treat AMD by reducing sulfate, increasing pH, and precipitating metals as metal sulfides. Twelve SRBRs were constructed and operated for 12 months to evaluate AMD bioremediation performance as a function of carbon source and inoculum. Several locally-sourced waste organic materials were characterized by carbon fractionation; two mixtures with the same carbon profile but originating from different sources were used as organic substrates. Microbial communities from two different soil types were used to inoculate the bioreactors. The use of cow manure, corncob, and pinewood as the carbon source and soil from a local pond shore as the inoculum resulted in the greatest bioremediation efficiency, with a pH increase from 2.85 to 6.80 and removals of >82% for total Fe2+, >86% for Cu2+, >88% for Zn2+, and >65% for SO42-. The source of inoculum was found to impact bioremediation startup, with sulfate reduction observed 20 days earlier in high-performing inocula. The carbon source was found to impact long-term bioremediation efficiency, with 24% more SO42− and 38% more Fe2+ removed by the best performing carbon sources. Altogether, the combination of manure as a carbon source and marina soil as an inoculum resulted in the highest bioremediation efficiency. The high metal and sulfate removals combined with pH increases to near neutral, validate the use of SRBRs as an effective method for long-term AMD bioremediation.

The use of chemical fertilizers with high doses and continuously in soybean cultivation can have a negative impact. Efforts to increase soybean production in an environmentally friendly manner need to be done, including using organic fertilizers and biological fertilizers. This study aims to determine the effect of doses of cow manure and kinds of biological fertilizers on the growth of soybean varieties Devon I. The research was conducted in Teguhan Village, Karangmalang District, Sragen Regency, altitude 86 m asl, with soil type Grumosol (PPT Vertisol). This study used a completely randomized block design (RAKL) with two treatment factors, namely the first factor the dose of cow manure consisted of 3 levels, namely P0 = 0 tons/ha, P1 = 10 tons / ha, P2 = 20 tons / ha, and kinds of fertilizers. Biological consists of 4 levels, namely H0 = without biological fertilizers, H1 = Trichoderma, H2 = mycorrhizae, H3 = Trichoderma and mycorrhizae. This study did not use inorganic fertilizers. The results showed that the dose of cow manure had a significant effect on soybean growth, but the type of biological fertilizer and the interaction between the dose of cow manure and the type of biological fertilizer had no significant effect on soybean growth. From the growth achieved, the use of cow manure accompanied by biofertilizer Trichoderma and mycorrhizae has the potential to increase soybean yields.

Soil Fertility Status on Organic Paddy Experiment

The study aims to determine fertility status of the soil after organic paddy experiments using kinds and doses of organic fertilizers. Experiment was conducted at greenhouse laboratory in Faculty of Agriculture Sebelas Maret University Surakarta. Experimental design used completely randomized design with 9 kinds of treatment was replicated 3 times. Experiments were the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations that are based on fulfilling nutrient requirements of 120 kg N ha -1 . Result shows that the use of cow manure, Azolla fertilizers and Azolla inoculum had no effect on changes of soil fertility status. Soil fertility status was not significantly correlated with cow manure (0,16 ns ), Azolla fertilizer (0,26 ns ) and Azolla inoculum (0,16 ns ). Average of final soil fertility status included fertile category, which was similar as the initial soil fertility status. Average of final soil properties of treatment but nevertheless was relatively higher than in no treatment, indicating the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations had greater impact to soil properties. Cow manure despite increased available K 2 O and dry grain, but it did not significantly increase the soil fertility status from fertile to very fertile. This was presumably due to the relatively short experiment period, only one planting season had not given significant effect to soil properties. Implication of this study is the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations although did not increase the soil fertility status but could maintain soil fertility status as the initial conditions before planting.

Observation of temperature and pH during biogas production from water hyacinth and cow manure

Biogas is generated from biological process of organic material by bacterial engaged. Biogas can be derived from manure, municipal waste, agricultural waste and other biomass resources. In addition to the use of cow manure as raw material for biogas production, it can also be derived from biomass containing cellulose which one is water hyacinth as an organic material that contains quite large cellulose. The abundance of water hyacinth found in Rawapening causing several negative impacts. The purpose of this study is to observe temperature and pH on the biogas production generated from water hyacinth of Rawapening and cow manure. Biogas production process begins by chopping the leaves and stems of water hyacinth, and then mixed with cow manure and water. The results of substrate variation of water hyacinth, cow manure and water reaches optimally at 40:80:480 respectively, which produce the highest point of biogas amounted 176.33 ml on the day 20 in 1L sized digester, the temperature of the biogas production is at 32°C. At the initial fermentation, digester temperature of 30°C has increased over the course of the fermentation process, a peak at day 20 and then decreased to 27°C at the end of fermentation. There is a decrease in pH starting from initial fermentation at pH 6-7 and then the pH began to decline until the end of fermentation as amount of pH 5.

Potential N mineralization and availability to irrigated maize in a calcareous soil amended with organic manures and urea under field conditions

Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous soil under field conditions. Selected soil samples were collected after different N sources application, and mineral N (NO3 - -N and NH4 + -N) was determined for a total of 110 days of field incubation, using the buried bag technique. Poultry manure-treated soils had significantly higher total N mineralization (244 kg ha -1 ) than CM (109 kg ha -1 ), UF (138 kg ha -1 ) and CM + UF (141 kg ha -1 ) treated soils. However, N availability was greater in UF (69%) and PM (61%) treated soils than that of CM + UF (47%) and CM (28%) fertilized soils. Shoot dry matter of maize and N uptake were considerably higher in PM treated soil than in UF, CM and CM + UF soils. Nevertheless, maize N recovery was significantly higher in urea soils (60%) than in PM (42%) and CM + UF (37%) soils followed by CM soil (15%). In conclusion, our data indicated that PM and the CM + UF that released N slowly resulted in high maize silage production, N uptake and N recovery following their application in these calcareous soils with low SOM content and N availability.

Can the nitrogen and carbon stable isotopes of the pygmy mussel,Xenostrobus securis, indicate catchment disturbance for estuaries in northern New South Wales, Australia?

The nitrogen and carbon stable isotope ratios (δ15N and δ13C) of the pygmy mussel,Xenostrobus securis, were determined for three estuaries with varying levels of catchment disturbance in northern New South Wales, Australia. The lower Manning River catchment supported the highest human population densities with 3% residential development and some livestock agriculture (41%); the Wallamba River catchment was mostly livestock agriculture (56%) while the Wallingat River catchment was mostly vegetated (79%). Mussels, estuarine particulate organic matter (POM), and livestock and human-derived waste were collected in two stages during the austral summers of 2001–2002 and 2002–2003 for dual carbon-nitrogen stable isotope analysis. The disturbed Manning and Wallamba River catchment mussels were enriched in15N by an average of 3.2‰ and 1.5‰, respectively, compared to the vegetated Wallingat River mussels. Mussel δ13C values ranged from −24.8‰ to −30.3‰ and showed an estuarine gradient becoming enriched with distance downstream within estuaries, but were unable to distinguish patterns in catchment disturbance between estuaries. The δ15N and δ13C values of POM showed a similar pattern to mussels, indicating a direct link between them within each estuary. A multiple regression model of mussel δ15N using the fractions of land used for livestock agriculture and residential development within 5 km zones from river networks to a distance equivalent to a tidal ellipse from sites explained 67% of the variation in mussel δ15N with 95% of the differences lying within 1.6‰ of observed values. Increasing fractions of land used for livestock agriculture depleted mussel δ15N values estimated by the regression equation, indicating the use of cow manure as a nutrient source with a value of 2.0‰. Increasing fractions of land used for residential development enriched estimated mussel δ15N, indicating the use of human-derived waste with a value of 20.8‰. Pygmy mussels are a useful long-term bio-indicator for the effects of anthropogenic catchment disturbance and nutrient enrichment in estuaries.

Cow Manure as an Ingredient of Turkey Diets

COW manure was found to have a marked beneficial effect on growth in chicks, if added to a diet deficient in riboflavin (Hammond, 1942). Bunyea and MacDonald (1942) found evidence that some strains of Aerobacter aerogenes and of Escherichia acidi lactici may be responsible for considerable poult mortality. These organisms are commonly present in cow manure. Hence it seemed possible that it might not be safe to use cow manure in turkey diets unless it was heated at temperatures that would destroy these bacteria.Accordingly an experiment was conducted at the U. S. Department of Agriculture, Beltsville Research Center, Beltsville, Maryland, to investigate the use of cow manure dried at different temperatures and of undried fresh cow manure in the diet of growing turkeys.MATERIALS AND METHODSFive lots of Beltsville Small White poults, 20 to the lot, were brooded in electrically heated battery brooders.
