Durian Rind

The case of waste from durian rind in Ngrogung, Ngebel, Ponorogo, Indonesia increased significantly per year. Agglomerations and decomposition of durian rind surrounding agro park caused air pollution and bad view in park areas. The decomposition of durian rind is very important to reduce those impacts. The micro composter model in Kampung Durian consisted of three main components. The first component was drying area with cemented ground. The drying area was set to accommodate 1 t fresh durian rind per day. The materials come from surrounding areas of agro park. The second was a machine house with one ton material capacity per day. The third was a composter house consisted of composter tube and packing area. The result of the micro composter house showed a cleaning agglomeration of durian rind from Ngebel lake and surrounding areas. In addition, the model produced liquid organic fertilizer and compost. A cycle of composting was 30 d in the dry season. Amount 1 t of durian rind decomposition resulted of 100 L liquid organic fertilizers and 50 kg compost. The result of composter had a direct impact to control waste problems in Ngebel and surrounding areas.

The study aimed to investigate an effect of organic fertilizer applied to rice in the first planting season for unfertilized soybean as second crop followed by inorganic and biofertilizer applied in the third season on soybean growth and yield under the rice-soybean-soybean cropping pattern in 2016/2017. The main plot was organic: (1) without organic amendment, (2) 10 t·ha−1 of chicken manure, and (3) 10 t·ha−1 precomposted rice straw. The subplot was inorganic N and P fertilizers and commercial biofertilizer (consisting of Rhizobium, nitrogen-fixing bacteria, and P-solubilizing bacteria) applied at planting of soybeans in the second dry season: (1) control (no inorganic and biofertilizer), (2) 50 kg urea ha−1, (3) 100 kg SP36·ha−1, (4) 50 kg urea + 100 kg SP36 ha−1, (5) biofertilizer, (6) biofertilizer + 25 kg urea ha−1, (7) biofertilizer + 75 kg SP36 ha 1, and (8) biofertilizer + 25 kg urea + 75 kg SP36 ha−1. Soybean planted on the first dry season after rice harvested was not fertilized (untreated). The results showed that the chicken manure amendment increased grain yield of soybean in the second season, i.e., from 1.03 t·ha−1 (without organic amendment) to 1.27 t·ha−1, an increase of 23%. There was no effect of rice straw on soybean grain yield. In the third season, however, the residual effect of straw compost or chicken manure increased soybean grain yield by 8% and 20%, respectively. Both straw compost and chicken manure also showed a positive effect on the use of inorganic and biofertilizers in increasing soybean productivity.

Rice yield and proper weed control need to be increased through an environmentally friendly agricultural system approach in rainfed land during the dry season by reducing the dosage of synthetic fertilizers. This study aims to determine the effect of different fertilizer applications on rice yield and weed abundance in rainfed land during the dry season. The study used a split-plot design, with the main plot of rice variety, i.e., Situ Bagendit and IR-64, and subplots of fertilizer, namely synthetic fertilizers (N, P, K), organic fertilizers + P60 + ½ dose of synthetic fertilizers, organic fertilizers + PGPR + ½ dose of synthetic fertilizer and organic fertilizer + P60 + PGPR + ½ dose of synthetic fertilizer with three replications. The variables observed were rice yield components, namely panicle length, total empty grain and content per panicle, grain weights per hill, effective plot and hectare, 1000 grain weight, harvest index, and weeds summed dominance ratio (SDR). The synthetic fertilizers and three various organic fertilizers, biological fertilizers, and synthetic fertilizers gave different results on the SDR of weeds. The weeds of Sphenoclea zeynalica and Cyperus difformis showed consistent dominance with higher SDR than other weeds, i.e.,> 15 and > 10, respectively. The application of organic and biological fertilizers with half the recommended dosage of the synthetic fertilizers is equivalent to applying the recommended dosage of synthetic fertilizers on rice yield during the dry season on the rainfed dryland with low rainfall intensity and a low yield of 1.3–1.7 t/ha.

The widespread use of chemical fertilizers has played an important role in China's agricultural development, but with the increasing input of chemical fertilizers, it has caused serious impact on the ecological environment, leading to agricultural non-point source pollution, food safety and many other problems. In order to promote the sustainable development of agriculture, China has issued a series of policies to popularize organic fertilizer in agriculture, which can not only improve the quality of agricultural products, promote agricultural production and increase income, but also make resource utilization of urban and rural organic wastes and protect the environment. Farmers are the main force of agricultural production and also the main body of rural environmental protection. It is of great significance to study farmers' ecological behavior. Through a survey of 407 farmers in the surrounding areas of Chengdu, Sichuan Province in 2019, and the logitstic model constructed based on the survey data, this article analyzed the factors influencing farmers' behavior in purchasing organic fertilizer. The results show that 12 indexes such as farmers' gender, education level, and the number of family farmers are the main factors influencing farmers' purchase of organic fertilizer. At the end, the article puts forward relevant policy recommendations to guide farmers to purchase and apply organic fertilizer.

Abstract The field trial was carried out in 2016 and 2017 on the grounds of the Botanical Garden of the Slovak University of Agriculture in Nitra. The aim of the paper was to test the impact of new organic fertilizers from Company Rokosan on the yield parameters and the morphological and phenological properties of tomatoes. In the experiments, we observed two determinant varieties, namely ‘Brixol F1’ and ‘Uno Rosso F1’. We used the bulk organic fertilizer Rokosan P, designed for fruiting vegetables, and the liquid fertilizer Rokohumin Z. Both forms of fertilizers are produced as organic biomineral fertilizers, their main ingredient being keratin. They contain 9% N, 9% P2O5, 9% K2O, 3% MgO and trace elements. The total harvest in the control variant without fertilization was the lowest compared to the fertilized variants. The second variant was fertilized with the Rokosan P fertilizer, and the harvests were in both years and in both varieties higher than in the variant 1. The third variant was fertilized with the Rokohumin Z, the liquid fertilizer and achieved the best crop yields per plant. For the ‘Uno Rosso F1’ the best total harvest weight was 7.2 kg per plant in 2016 and 8.96 in 2017. For the ‘Brixol F1’, the highest harvest was 8.14 kg per plant in 2016 and 9.24 kg in 2017. In terms of yields and the number of fruits, combined fertilization with the bulk fertilizer Rokosan P and the liquid fertilizer Rokohumin Z reached the second highest values.

Intisari   Pencemaran udara yang bersumber dari aktivitas antropogenik dewasa ini menjadi semakin meningkat seiring dengan berkembangnya sektor industri dan transportasi. Kabupaten Tangerang dan sekitarnya merupakan daerah industri besar di Indonesia, sehingga masyarakat di wilayah tersebut memiliki potensi terpapar pencemar udara yang tinggi. Salah satunya adalah partikulat.  Sebaran partikulat dipengaruhi oleh beberapa hal diantaranya jumlah sumber emisi, serta faktor meteorologi terutama angin. Pemantauan sebaran pencemar perlu dilakukan sebagai pertimbangan untuk mengambil kebijakan terkait masalah lingkungan. Namun pemantauan pencemar terkendala oleh biaya yang besar dan ketersediaan alat di lapangan, sehingga untuk memudahkan melakukan pemantauan digunakan model sebaran pencemar. Penelitian ini bertujuan untuk mengetahui arah sebaran pencemar PM10 di wilayah Kabupaten Tangerang dan sekitarnya berdasarkan arah angin pada musim kemarau. Metode dalam penelitian ini menggunakan model Chimere yang dapat menghasilkan prakiraan pencemar udara harian, termasuk aerosol dan polutan lain. Hasil analisis menunjukkan konsentrasi PM10 tinggi di daerah sekitar Kotamadya Tangerang. Banyaknya industri dan padatnya kendaraan bermotor serta angin dominan yang menuju timur pada musim kemarau menyebabkan konsentrasi PM10 di Kota Tangerang Selatan hingga Kota Tangerang lebih tinggi daripada di sekitarnya, yakni mencapai 26-28 μg m-3. Nilai korelasi antara kecepatan angin dan konsentrasi partikulat sebesar -0.46 menunjukkan kecepatan angin cukup mempengaruhi tingkat konsentrasi PM10.   Abstract  Air pollution originating from anthropogenic activities nowadays be increased along with industry development and transportation sector. Tangerang District and its surrounding areas are a large industrial area in Indonesia, so people in the region have a high potential for exposure to air pollutant. Particulate is one of the pollutions. Monitoring the pollutant dispersion is necessary to be conducted as a consideration to take a policy related to environmental issues. However, pollutant monitoring constrained by cost and availability of tools in the field, so the model is used to make pollutant monitoring easier. This study aims to determine the direction of PM10 pollutant dispersion in Tangerang  and the surrounding area based the dominant wind direction in the dry season. The method in this study uses Chimere model that can generate daily air pollution forecast. Result shows high PM10 concentration around Tangerang City. High number of industries and vehicles and also the dominant winds eastward in the dry season led to a concentration of PM10 in Tangerang City until South Tangerang City higher than around, namely reached 26-28 μg m-3. Correlation value between wind speed and particulate concentration is -0.46 indicated that the wind speed has considerable influence the level of PM10 concentrations.

AbstractNortheastern Thailand relies on agriculture as a major economic activity, and has used high levels of agrochemicals due to low facility, and salty sandy soil. To support soil recovery and sustainable agriculture, local farmers have used organic fertilizers from farmed animal feces. However, knowledge about these animal fecal manures remains minimal restricting their optimal use. Specifically, while bacteria are important for soil and plant growth, an abundance and a diversity of bacterial composition in these animal fecal manures have not been reported to allow selection and adjustment for a more effective organic fertilizer. This study thereby utilized metagenomics combined with 16S rRNA gene quantitative PCR (qPCR) and sequencing to analyze quantitative microbiota profiles in association with nutrients (N, P, K), organic matters, and the other physiochemical properties, of the commonly used earthworm manure and other manures from livestock animals (including breed and feeding diet variations) in the region. Unlike the other manures, the earthworm manure demonstrated more favorable nutrient profiles and physiochemical properties for forming fertile soil. Despite low total microbial biomass, the microbiota were enriched with maximal OTUs and Chao richness, and no plant pathogenic bacteria were found based on the VFDB database. The microbial metabolic potentials supported functions to promote crop growth, such as C, N and P cyclings, xenobiotic degradation, and synthesis of bioactive compounds. Pearson’s correlation analyses indicated that the quantitative microbiota of the earthworm manure were clustered in the same direction as N, and conductivity, salinity, and water content were essential to control the microbiota of animal manures.

Centrality Analysis

AbstractIn this paper, we analyzed the spatial and temporal causality and graph-based centrality relationship between air pollutants and PM2.5 concentrations in China from 2013 to 2017. NO2, SO2, CO and O3 were considered the main components of pollution that affected the health of people; thus, various joint regression models were built to reveal the causal direction from these individual pollutants to PM2.5 concentrations. In this causal centrality analysis, Beijing was the most important area in the Jing-Jin-Ji region because of its developed economy and large population. Pollutants in Beijing and peripheral cities were studied. The results showed that NO2 pollutants play a vital role in the PM2.5 concentrations in Beijing and its surrounding areas. An obvious causality direction and betweenness centrality were observed in the northern cities compared with others, demonstrating the fact that the more developed cities were most seriously polluted. Superior performance with causal centrality characteristics in the recognition of PM2.5 concentrations has been achieved.

Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.

Influence Of Substrate

Over a 5 year period, we examined the influence of substrate and fertilization on nursery growth and outplanting performance of Norway spruce (Picea abies (L.) Karst.). We focused on the relative growth and development of roots and shoots and the colonization intensity and diversity of ectomycorrhizal (ECM) fungi. In the nursery, a conventional substrate (low-humified Sphagnum peat) supplemented with woody material (wood fibre and pine bark) and either mineral or organic fertilizers yielded shorter seedlings than those grown on the unmodified substrate. However, after outplanting, the growth rate of seedlings cultivated on modified substrates was higher than that of seedlings grown on the unmodified substrate. Seedlings cultivated in modified substrates had significantly higher root/shoot ratios and ECM diversity; the latter remained significant after ≥3 years of outplanting. Seedlings grown on a substrate containing 50% woody material and supplemented with organic fertilizer had the highest growth rate among all seedlings during the 3 year period of outplanting. Colonization intensity of ECM fungi was high in all seedlings except for those grown in heavily fertilized substrate. This study suggests that nursery techniques that produce seedlings with higher root/shoot ratios and ECM diversities could improve plantation success and growth rate for at least the first 3 years of outplanting.
