Assessing the Quality of Organic Fertilizer Products Made from Cow Dung in Wonogiri Regency, Indonesia

Kebonagung Sub-district, Sidoharjo District, Wonogiri Regency is the Wonoagung Wonogiri Organic Farming Association (PPOWW) location. Mitra is an organization engaged in organic rice and cattle cultivation. The conversion of bovine dung into organic fertilizer, particularly liquid fertilizer containing biological agents, is one of the waste elimination strategies employed to prevent environmental contamination. The nutrient content of organic fertilizer material sources varies. Organic fertilizer of high quality conforms to the Standard for Organic Fertilizers established by the Ministry of Agriculture of the Republic of Indonesia. Only some producers are aware of the standard quality requirements for organic fertilizer. It is necessary to analyze the nutrient content of organic fertilizer products to determine whether the quality of organic fertilizer is excellent. A preliminary survey of partner conditions, preparation of materials (organic fertilizer), and analysis of fertilizer content are among the activities performed. The C/N ratio of organic fertilizer is 8.41, and its pH is 7.6. The analysis results indicate that the Wonoagung Wonogiri Organic Agriculture Association's organic fertilizer products meet the liquid organic fertilizer quality standards. This condition demonstrates that the raw materials used in organic fertilizer production are of high quality and that the appropriate procedures have been followed. Adding biological agents to the production of organic fertilizer can enhance the quality of the finished product.

Nitrogen fertilization value of compost and dried dung in soils with contrasting synthetic nitrogen fertilization histories

AbstractIf the production of forage for dairy cattle is to become less reliant on synthetic nitrogen (N) fertilizers, there is need to better understand and account for the N contributed by on‐farm and imported organic amendments. A 254‐day aerobic soil incubation study (typical length of a growing season in many temperate dairying regions) quantified the inorganic (mineral) N supply from a commercial compost and dried bovine dung (i.e., on‐farm effluent solids). Amendments were incubated in soils with contrasting synthetic N fertilization histories (i.e., 70–100 vs. 350–400 kg N/ha per year) to evaluate if higher synthetic N fertilization histories would reduce the lag time that often exists between organic amendment application and significant release of inorganic N for plant uptake. This proposition was based on previous research, which showed greater soil inorganic N availability accelerating organic amendment decomposition. Our experiment did find that the release of inorganic N from evaluated organic amendments was greater in soils with higher synthetic N fertilization histories, but that this effect was not apparent until after the first 6‐months of this 9‐month experiment. Despite this finding, soils with contrasting synthetic N fertilization histories were not found to differ in their initial inorganic N content, nor microbial activity or other physiochemical properties known to affect N mineralization. Our study highlighted the long‐term vision needed when transitioning from synthetic N fertilizers to organic amendments, with most of the N present in the compost and dried dung remaining unavailable for forage production (i.e., remained bound in organic carbon‐based molecules).

Two New Species and New Records of Sepsidae from the Brazilian Amazon.

The dipteran fauna from the Brazilian Amazon remains poorly known, including that of forensic interest, such as the Sepsidae. The sepsid fauna of two secondary forests in the eastern Amazon was surveyed utilizing rotting bovine lung and feces (humans, bovines, and monkeys). We obtained 17 sespid species in six genera, most of them on bovine dung and rotting bovine lung. Two new species are described herein: Archisepsis bosque sp. nov. and Archisepsis verae sp. nov. The genus Palaeosepsis Duda, 1926 and the species Archisepsis polychaeta (Ozerov, 1993), Archisepsis diversiformis (Ozerov, 1993), Microsepsis mitis (Curran, 1927), Meropliosepsis sexsetosa Duda, 1926, and Palaeosepsis cf. golovastikOzerov, 2004 are newly recorded from the Brazilian Amazon.

Optimization of Biogas Production from Sewage Sludge: Impact of Combination with Bovine Dung and Leachate from Municipal Organic Waste

Biogas is a bioenergy produced from organic or all types of biological degradable wastes and could make it possible to limit energy dependence. Sludge is the best alternative substrate for biogas production at a community-level biogas plant. The literature shows that co-digestion can increase the efficiency of sludge anaerobic digestion. This research, thus, focused on (i) determining the conditions of optimal biogas production in the co-digestion of primary sludge (PS) and bovine dung (BD), (ii) evaluating the impact of leachate from organic waste and cellulose on biogas production. Primary sludge was collected in Bacau town wastewater treatment plant in Romania. The sampling of municipal solid waste was carried out in Ouagadougou pre-collect centers (Burkina Faso). Batch tests were conducted in glass bottles through anaerobic digestion (1 L). The following parameters were monitored during the digestion process: pH, volatile fatty acid (VFA), volatile solids (VS) and biogas production. Primary sludge, bovine dung and leachate showed 50.51%, 72.41% and 70.48% of volatile solids content, respectively. Sludge showed good stability, unlike the other two substrates, such as bovine dung and leachate, with VFA to alkalinity ratio 0.54. Leachate from organic waste had high values of VFA to alkalinity ratio > 3600. Co-digestion could make it possible to raise the levels of organic matter and improve microbial growth and the stability of anaerobic biomass. The best biogas production yield of 152.43 mL/g VS was obtained with a combination of 30% bovine dung and 70% primary sludge at 45 °C, with a 21.57% reduction in organic matter. An improvement in biogas productivity was effective with the addition of leachate, which could be used as an additive element during anaerobic digestion.

Crop Protection Practices in Traditional Agriculture in mid-hills of Western Nepal: A Case of Palpa and Gulmi District

A field survey was conducted in two districts­­ of western hills of Nepal during July-August, 2020 to study about the practices of traditional methods of horticultural crop disease management. A total of 125 farmers, 10 traders, 5 agro-vets, and 3 plant clinical doctors from four local bodies of two districts; Palpa and Gulmi, were selected for the interviews which employed a pretested questionnaire. Descriptive statistics were used to analyze the data. Almost half of the farmers interviewed (48%) were found to have an average level of knowledge regarding the application of indigenous methods. Mixture of kerosene and ash, mugwort solution, plant residues, bovine dung and urine, chilli powder, papaya leaves, onion mixed with garlic, etc. were popular as traditional techniques to effective control of disease and pest. Scaling technique used in this study showed the lack of indigenous information as the most serious constraint in adoption of traditional means, followed by lack of advertisement, poor social perception of farmers, and weak cooperation among social and agricultural scientists. The study recommended that documentation and scientific validation of indigenous means and support from government and extension agents are necessary to encourage farmers using traditional means. This study examines traditional diseases/pests control strategies implemented by the ancients and presently adopted in ongoing practices.

Carbon Neutral: The Failure of Dung Beetles (Coleoptera: Scarabaeidae) to Affect Dung-Generated Greenhouse Gases in the Pasture.

Research suggests dung beetles can churn, aerate, and desiccate dung in ways that influence the dung and soil microbes producing greenhouse gases (GHGs). We examined the impacts of the tunneling beetle, Onthophagus taurus (Schreber), and the dwelling beetle, Labarrus pseudolividus (Balthasar), on the carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emitted from pasture-laid bovine dung as well as their sum-total (CO2 + CH4 + N2O) effect on global warming, or their carbon dioxide equivalent (CO2e). Despite dung beetles potential effects on CH4 and N2O, the existing literature shows no ultimate CO2e reductions. We hypothesized that more dung beetles would degrade pats faster and reduce CO2e, and so we increased the average dung beetle biomass per dung volume 6.22× above previously published records, and visually documented any dung damage. However, the time effects were 2–5× greater for any GHG and CO2e (E = 0.27–0.77) than dung beetle effects alone (E = 0.09–0.24). This suggests that dung beetle communities cannot adequately reduce GHGs unless they can accelerate dung decomposition faster than time alone.

Recovery and seeds germination of four important tropical forage legumes in bovine dung

This experiment was conducted to evaluate the recovery and survival of tropical forage legume seeds (butterfly pea, stylosanthes, perennial soybean and macrotiloma) subjected through the digestive tract of cattle and to evaluate the germination of the seeds in feces of cattle. A 50 g of seed mixed with 150 g of mineral supplement offered to the cattle. Each cattle was considered as repetition. The bovine feces collected up to 60 hours after eating the seeds, where the seeds separated by sieves, using water, gloves procedure and tweezers. Later, they counted and divided into intact and swollen. For the germination test of the recovered seeds, 75 seeds per replicate were used (25 in natura, 25 intact and 25 swollen seeds, respectively). For the germination test in fecal plates, the bovine feces collected between 12 and 30 hours after eating the seeds. After 120 days, we evaluated the total amount of plants emerged within the study period (between 12 and 30 hours) and the average number of emerged plants per fecal signs. The results showed that cattle are facilitating the dispersion of butterfly pea, macrotyloma and perennial soybean, but not stylosanthes. The highest survival as the average number of germinated plants in fecal plates achieved by macrotyloma, followed by butterfly pea species and perennial soybean. The cattle were efficient in the pasture colonization process, due to the considerable dispersion of the seeds. This dispersion was not observed for seeds of stylosanthes.

Influence of organic pre-sowing seed treatments on germination and growth of rosemary (Rosmarinus officinalis L.)

ABSTRACTRosemary (Rosmarinus officinalis L.) is an important medicinal and aromatic herb, used by various pharmaceutical, food and cosmetics industries. For most species, seed-based multiplication is effective and convenient, but for rosemary, seed germination is a problem due to the mucilaginous seed coat, and sometimes the germination is no more than 10–20% resulting in non-uniform crop establishment. This investigation was carried out to improve seed germination by using low-cost organic seed priming techniques. Eleven pre-sowing seed treatments were tested, based on locally available resources, including: soaking seeds in water (cold and hot), bovine urine (5%, 10%, 15% and 20% concentration), bovine dung slurry, buttermilk, compost tea and Agnihotra ash, and comparing with an untreated control. All the pre-sowing seed treatments increased the percentage of seed germination in rosemary compared with the control, except buttermilk, which had an adverse effect. Among the different treatments, seed germination was significantly increased to 46.7% for seeds treated with bovine dung slurry and to 42.0% for seeds treated with bovine urine5.0%, compared with those in the control where the germination was 9.7%. The bovine dung slurry treatment also recorded uniform and early germination (9 days for initiation and completion at 43 days) resulting in a significantly higher rate of germination (1.4) than the control. The number of leaves, the root length and the seedling vigour were also recorded to be the highest for seeds treated with bovine dung slurry, followed by bovine urine5.0%.

Habitat Association Promotes Diversity of Histerid Beetles (Coleoptera: Histeridae) in Neotropical Ecosystems

We aimed to verify how distinct habitats (forest, cerrado, rupestrian field, and introduced pasture) and attractive baits contribute to histerid beetle distribution in the Serra de Sao Jose, Brazil. Beetles were sampled using baited pitfall traps (50 g of omnivore dung, bovine dung, or bovine carcass), resulting in the collection of 1,129 individuals representing 22 species. Histerid diversity was reduced in areas with low vegetation complexity, where we also observed a high dominance of Hister cavifrons Marseul. Meanwhile, Euspilotus excavata Arriagada was abundant and exclusive in the forest. Habitats exhibited distinct histerid communities according to a ANOSIM test, but the same test failed to find that baits attracted different “communities” of species. These results highlight the simplification process acting after habitat degradation, with a prevalence for common species with a large geographic distribution. Our results also show the importance of habitat diversity at the landscape level to histerid biodiversity in the Neotropics.

The (d)evolution of scientific temper in India

Jawaharlal Nehru was most instrumental in instilling scientific temper at the birth of modern India. In contrast, as Bharatiya Janata Party came into power in 2014, their top-down governance is explicitly trying to promote Vedic science. The Prime Minister boasted off of genetics in Mahabharata, and plastic surgery in the Vedas. The origin of Heisenberg’s uncertainty principle form the Vedas is the pride of the Home Minister. The Minister of Science and Technology contended that the Vedas contain better theory than E = mc2. There is increased veneration of cattle. A large-scale promotion of bovine urine and dung as medicine, called cowpathy or, as they embrace it, panchagavya is on the rise. To that effect, gold was discovered in the urine of Gir cows, but really to no effect. Their cows breathe in and out oxygen, and peafowl are confirmed celibates. The Minister of State for Human Resources Development ridiculed evolutionary biology proclaiming that Darwin’s theory is scientifically flawed. We, the people of India, deserve better wisdom. As Nehru would have put it, “a baseless dogma or a hopeless aspiration” of this sort will never elate India, or any nation for that matter, to scientific progression, not to say economic and social developments.

Application of an embryonated chicken egg model to assess the vector competence of Australian Culicoides midges for bluetongue viruses.

Culicoides biting midges (Diptera: Ceratopogonidae) are vectors of a number of globally important arboviruses that affect livestock, including bluetongue virus (BTV), African horse sickness virus and the recently emerged Schmallenberg virus. In this study, a model using embryonated chicken eggs (ECEs) was utilized to undertake vector competence studies of Australian Culicoides spp. for 13 laboratory-adapted or wild-type virus strains of BTV. A total of 7393 Culicoides brevitarsis were reared from bovine dung, and 3364 Culicoides were induced to feed from ECEs infected with different strains of BTV. Of those, 911 (27%) survived the putative extrinsic incubation period of 9-12 days. In some trials, virus was also transmitted onward to uninfected ECEs, completing the transmission cycle. This model does not rely on the use of colonized midges and has the capacity to assess the vector competence of field-collected insects with strains of virus that have not previously been passaged in laboratory culture systems. There is also potential for this model to be used in investigations of the competence of Culicoides spp. for other arboviruses.

The paper promotes the inexperienced energy that is being worldwide supported by many countries. inexperienced energy is that the type of energy obtained from non-exhaustible resources. Technologies that promote inexperienced energy embody renewable energy sources, like electricity, alternative energy, wind energy, wave power, heat, bioenergy, periodic event power. The paper has analyzed utilization of bovine dung and human manure waste for electricity generation through a varied case studies on biomethanation station. There square measure or so twenty Million bovine and a couple of Million human population within the within the single district of geographic area. Nearly five hundredth of bovine dung and human manure is being sold-out for agricultural suggests that and also the remaining is drained off into a close-by drain. The drained off bovine dung and human manure will be used for power generation supporting inexperienced energy while not touching nature and fewer carbon emission. The paper has studied the political economy of power generation of Biogas methanation station and has found that it's profitable to utilize the bovine dung and human manure for electricity generation, the capital investment depends on the capability of the plant and payback amount being most four to six years. Besides electricity generation the plant additionally provides bio-manure. It additionally checks pollution and emission of greenhouse gases. The study has urged that such plants ought to be established not solely all told the districts of geographic area however additionally in whole country to assist in electricity generation. the massive farmers ought to represent Non Govt. Organization (NGOs), Consultancy’s and aid cluster (SHG) to determine such plants in their various areas. The central and regime provides the required steering and backing for the institution of such plants.

Impact of freezing on the emergence of Culicoides chiopterus and Culicoides dewulfi from bovine dung

The emergence of Culicoides chiopterus (Meigen), 1830 and C. dewulfi Goetghebuer, 1936 (Diptera: Ceratopogonidae) from cowpats in northwestern Germany was investigated. In order to investigate the survival of both species at low temperatures, cowpat subsamples were frozen for 48h at −18 and −21°C. Emergence from frozen and non-frozen samples was compared. The number of emerging adults of C. chiopterus from samples frozen at −18°C was greatly reduced and no emergence was observed from samples frozen at −21°C. No adult C. dewulfi emerged from frozen samples, suggesting this species is less resistant to these temperatures, compared to C. chiopterus.

Assessment of the abundance of Culicoides chiopterus and Culicoides dewulfi in bovine dung: A comparison of larvae extraction techniques and emergence traps

We compared two larvae extraction methods involving sugar-flotation and an adapted Berlese funnel-extraction with emergence traps. This was done in order to analyse the colonisation of cowpats by Culicoides chiopterus (Meigen 1830) and Culicoides dewulfi (Goetghebuer 1936) (Diptera: Ceratopogonidae) and to gain information on the comparability and efficacy of these three methods. With all three methods, a considerable number of individuals was obtained. Significantly more individuals were obtained via sugar-flotation and Berlese funnel-extraction compared to the emergence traps. These differences, likely due to natural mortality and sample processing are discussed. We recommend Berlese as an efficacious method for extracting Culicoides larvae from bovine dung. It produces data rapidly and extracted larvae are viable. In comparison with Berlese, slightly more larvae were obtained by sugar-flotation, but this method was very labour intensive.

Dung beetles (Coleoptera: Scarabaeoidea) in three landscapes in Mato Grosso do Sul, Brazil

Dung beetles (Coleoptera: Scarabaeoidea) in three landscapes in Mato Grosso do Sul, Brazil. Dung Beetles are important for biological control of intestinal worms and dipterans of economic importance to cattle, because they feed and breed in dung, killing parasites inside it. They are also very useful as bioindicators of species diversity in agricultural or natural environments. The aims of this paper were to study the species richness, and abundance of dung beetles, helping to answer the question: are there differences in the patterns of dung beetle diversity in three environments (pasture, agriculture and forest) in the municipality of Dourados, in the state of Mato Grosso do Sul. A total of 105 samplings were carried out weekly, from November 2005 to November 2007, using three pitfall traps in each environment. The traps were baited with fresh bovine dung, and 44,355 adult dung beetles from 54 species were captured: two from Hyborosidae and 52 from Scarabaeidae. Five species were constant, very abundant and dominant on the pasture, two in the agricultural environment, and two in the environment of Semideciduous forest. Most of the species were characterised as accessories, common and not-dominant. The species with higher abundance was Ataenius platensis Blanchard, 1844. The indexes of Shannon-Wiener diversity were: 2.90 in the pasture, 2.84 in the agricultural environment and 2.66 in the area of native forest. The medium positive presence of dung beetles in the traps in each environment were: 36.88, 42.73 and 20.18 individuals per trap, in the pasture, agricultural environment and in the native forest, respectively. The pasture environment presented a higher diversity index. The species diversity of dung beetles was superior where there was higher abundance and regularity of resource (bovine dung).
