Chemical fertilizers currently poison arable agriculture, so organic fertilizers are now a new trend for soil improvement. This study investigates the appropriate ratio of fertilizer use and materials mixed with sewage sludge in the anaerobic co-digestion treatment method, which will best support agriculture. In the study, bio-organic fertilizer was composted of the co-digestion anaerobic with sewage sludge and agricultural wastes such as rice husk, rice husk charcoal, water hyacinth, cassava peel, and then tested on rice. The specific criteria of fertilizers such as total organic (TOC), total nitrogen (TN), and effective phosphorus (P2O5) and plant growth parameters such as germination rate (%), tillering rate, total weight (g) were evaluated. Initial results show the untreated sludge can be impacted negatively on plant development. The concentration of nutrients in the co-digestion composts was meet the requirements of the Ministry of Agriculture’s standards of organic fertilizer. These bio-fertilizers will play an important role in soil productivity and sustainability. Hence, the widespread use of organic fertilizers from waste to partially replace chemical fertilizers will open up opportunities to reduce farming costs for farmers and develop agriculture sustainably.

Antibiotic Residues

Recycling of organic wastes in agricultural ecosystems to partially substitute chemical fertilizer is recommended to improve soil productivity and alleviate environmental degradation. However, livestock manure- and sewage sludge-derived amendments are widely known to potentially carry antibiotic residues. The aim of this study is to investigate how substituting organic fertilizer for chemical fertilizer affects soil quality and antibiotic residues in agricultural soil, as well as their tradeoffs. A field experiment was conducted with the different treatments of pig manure and sewage sludge as typical organic fertilizers at equal total nitrogen application rates. The analysis of variance showed that the increments on the levels of residual antibiotics in the agricultural soils due to organic substitution for chemical fertilizer by pig manure and sewage sludge were observed. The antibiotic residues ranged from 13.73 to 76.83 ng/g for all treatments. Partial organic substitution significantly increased the sequestration of antibiotics in agricultural soil by 138.1~332.5%. Organic substitution will also significantly improve soil quality, especially for nutrient availability. Based on principal component analysis, organic substitution will strongly affected soil quality and antibiotic contamination. Pearson’s correlation showed that soil physicochemical properties had significant correlations with concentrations of antibiotics in soil, indicating organic fertilizers can promote the persistence of antibiotics in soil by modifying soil quality. To balance the benefits and risks, appropriate management practices of organic fertilizers should be adopted.

15N Abundance

Natural nitrogen isotope abundance (δ15N) has been suggested as a potential indicator for discriminating organic vegetables from their conventional counterparts. However, little is known about the δ15N characteristic of cauliflower (Brassica oleracea L. var. botrytis) under organic production and how the application of chemical fertilizers could affect this characteristic. In this study, δ15N characteristics of cauliflower (including the intra-plant δ15N characteristic) and soil under different fertilization treatments were investigated under field conditions. Five treatments were laid out: control, chemical fertilizers (F4M0), organic fertilizer (F0M4), and chemical fertilizer in combination with organic fertilizer at the ratio of 3:1 (F3M1) and 1:3 (F1M3). Results showed that plant δ15N was positively correlated with fertilizer δ15N and plant root/flower was more sensitive to changes of fertilizer δ15N and soil δ15N than leaf/stem. Distribution of δ15N in different plant parts (especially in flower and leaf) was significantly changed when organic fertilizers were partially or totally substituted by chemical fertilizers, suggesting a comparison of flower δ15N and leaf δ15N might be applicable for the organic identification of marketed cauliflowers. Our results provide fundamental data for the soil- and fertilizer-specific crop δ15N database and indicate that the intra-plant δ15N characteristic could be helpful for organic cauliflower identification.

In the development of vegetable farming by the community, there are fundamental problems which are generally carried out conventionally with the use of synthetic fertilizers and pesticides to determine the success of their farming. With the farming system, the community suffers a lot of losses because the inputs used are relatively expensive and on the other hand the products become cheap because the quality is not guaranteed. The solution to this problem is to develop bio-culture organic fertilizers and bio-urine whose raw materials are available in the region. The partner village development program aims to conduct training on the making and development of liquid organic fertilizer bio-culture and biourine to support the cultivation of organic vegetables. The method of approach applied is technology transfer (TT) and entrepreneurship capacity building (ECB) which is carried out with the Participatory Rural Approach (PRA) approach ) which in its implementation uses the method of lecture/discussion, training, making demo plotting, and assistance. The results achieved in the implementation of this program were that participants were able to make and develop liquid organic bioculture fertilizers and biourin and apply it to their farms as an alternative to chemical fertilizers

The experiment assessed the influence of various biofertilizers and biostimulants on the growth characteristics of the root system, its colonization by arbuscular mycorrhizal fungi and the yielding of sweet cherry trees in field conditions. The experiment, conducted in Pomological Orchard of Research Institute of Horticulture located in Skierniewice during 2011–2014, involved the use of a mycorrhizal substrate, organic fertilizers and biostimulant in randomised block design. The control combination consisted of plants fertilized with mineral fertilizers (NPK). The use of the organic fertilizer BF Ekomix in dose 100 g per tree each year in the spring significantly increased the number of root tips in comparison with the control trees. There was also a tendency for the roots to lengthen and increase their surface area under the influence of this biofertilizer. In addition, the inoculation of roots with the mycorrhizal substrate in dose 200 g per tree per year stimulated the colonization of the roots of sweet cherry trees by arbuscular mycorrhizal fungi, which in turn led to improved root growth parameters.

Phytotoxic Effect

Introduction. Nowadays, in front of large cities, there is an acute problem for finding ways of environmentally safely dispose of accumulated sewage sludge and the possibility of its use. The most profitable way to utilize sewage sludge is to use them as organic fertilizers in agricultural production due to the high content of biogenic elements (nitrogen, phosphorus, potassium) and organic substances in their composition. However, the presence of heavy metals, pathogens, and other toxicants necessitates the study at the regional level the possibility of using these sediments as fertilizers. In each specific case, it is necessary to apply a scientific approach to the use of sewage sludge, since their composition is characterized by a qualitative and quantitative variation of chemical compounds. The purpose of the study was a hygienic justification for the possibility of using sludge for wastewater treatment from the municipal facilities in agricultural production as an organic fertilizer. Material and methods. The object of the study was sludge after treatment with flocculants and centrifugation and sludge stored on the sites of Lviv municipal facilities for 1, 6 and 18 months. In the experiment, the distribution of sludge components in the “plant-soil” dynamic system, as well as the degree of their accumulation in test plants, was determined. Quantitative determination of the of chemical elements content in samples of sludge and phytomass was carried out by atomic absorption spectrophotometry. Results. The effectiveness of the use of sludge from the municipal facilities for wastewater treatment in agricultural production as an organic fertilizer has been studied. It was found that the sludge dose of 50 tons/ha, using immediately after centrifuge, can not be used in the fields as a fertilizer. This dose caused a high phytotoxic effect on plants. The dose of used sludge (30 tons/ha after 1.5 years of maturing on silty areas) had a less pronounced phytotoxic effect, but the fact of fluorine, lead, cadmium, arsenic, mercury and manganese translocation from soil into the plants in high quantities was observed. This dose also cannot be used in the fields as a fertilizer. The use of a smaller dose should be justified by additional experiments.

Reduction of chemical fertilizers and effective use of livestock excrement are required for the realization of sustainable agriculture and reduction of greenhouse gas (GHG) emissions. The purpose of this study was to estimate the reduction rate of GHG emissions represented by comparing global warming potential (GWP) using organic fertilizers instead of chemical fertilizers. The study was conducted in a managed grassland on Andosol in southern Hokkaido for 3 years from May 2017 to April 2020. There were five treatment plots: no fertilizer, chemical fertilizer, manure, slurry, and digestive fluid. Organic fertilizers were applied such that the amount of NPK did not exceed the recommended application rate, and the shortage was supplemented with chemical fertilizers. Fluxes in CO2 caused by heterotrophic respiration (RH), CH4, and N2O were measured using the closed chamber method. Net ecosystem carbon balance (NECB) was obtained as net primary production + organic fertilizer application—RH—harvest. The GWP was estimated by CO2 equivalent NECB and CH4 and N2O emissions in each treatment. Chemical fertilizer nitrogen application rates in the organic fertilizer treatments were reduced by 10% for manure, 19.7% for slurry and 29.7% for digestive fluid compared to chemical fertilizer only, but the grass yields were not significantly different among the fertilizer treatments. The 3-year NECB showed significantly smallest carbon loss in manure treatment, and smaller carbon loss in the organic fertilizer treatments than in the chemical fertilizer only. The reduction rate in the GWP with use of organic fertilizers relative to that of chemical fertilizer was 16.5% for slurry, 27.0% for digestive fluid, and 36.2% for manure. The NECB accounted for more than 90% of the GWP in all treatments. CH4 emissions were < 0.1% of the GWP. On the other hand, N2O emissions accounted for more than 5% of the GWP, and was larger in the order of slurry > chemical fertilizer only > digestive fluid > manure. As a conclusion, these organic fertilizers can be used without no reduction of crop yield instead of chemical fertilizer, however, manure is the best way to increase soil carbon and to decrease GWP, followed by digestive fluid.

Curly red chili (Capsicum annum L.) is widely cultivated us-ing inorganic fertilizers which causes high production costs. Chili is valued because of the level of spiciness. The level of spiciness of chili is determined by the level of capsaicin which is affected by nutrients in the growing media. The nutrient of the planting media can be fulfilled by degrading the growing media by microbes in organic fertilizer. One type of organic fertilizer containing degrading microbes is biofertiliz-er. Biofertilizer and biogas sludge is one of the organic fertilizers con-taining microbes and organic materials that are able to support nutri-ent levels of the planting medium. This study aimed to analyze growth parameters include chlorophyll content and measure capsaicin levels in curly red chili. Which given biofertilizer and biogas sludge in vari-ous dosage and determine the optimum dose of the fertilizer. The study was conducted at an agricultural demonstration plot in Wukirsari Vil-lage, Cangkringan, Sleman. The study design used RCBD (Randomized Complete Block Design), the data were analyzed by ANOVA (Analysis of Variance followed by Duncan’s Multiple Distance Test (DMRT) at the 95% confidence level. The highest growth parameters and capsa-icin content were obtained on curly red chili plants which were given biogas sludge 36 mL + biofertilizer 10 L / ha. The application of bi-ofertilizer and biogas sludge in various concentrations given has not been able to increase the average total chlorophyll content of curly red chili plants. Thus, it can be concluded that the most appropriate dose of curly red chili is 36 mL biogas sludge + 10 L bio fertilizer/ha
