Abstract The properties and effects of organic fertilizers are different, including the ability to improve soil fertility and the potential of stabilizing heavy metals in soils that have not been explored in depth. In this study, three organic fertilizers from different raw materials were characterized and evaluated. The mushroom residue organic fertilizer (MO) had higher C, H, and O contents and more functional groups (-OH, C-H, and C=O), and its application significantly increased pH (1.00~1.32 units), organic matter (OM) content (26.58%~69.11%) and cation exchange capacity (CEC) (31.52%~39.91%) of soil. MO treatment also reduced the toxicity characteristic leaching procedure (TCLP)-Cd (24.21%) and TCLP-As (18.44%) concentration in the soil. That inhibited the mobilization of Cd and As from soil to plant, especially to plant shoots, and positively affected the plant growth and biomass. Redundancy analysis (RDA) showed that 40.09 % of total plant variation was related to soil properties (pH, OM, and CEC). Furthermore, the heavy metal risk assessment for all organic fertilizers was at safe levels. This study provides a valuable reference for the selection of organic fertilizers. Besides, it recommends organic fertilizers as economic and multi-effect amendments with safe use and provides a new option for the ‘simultaneous production and remediation’ of farmlands with low pollution.

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 results of a study of the effectiveness of the joint application of potato mineral and organic fertilizers are presented. The studies were carried out in 2017–2018. on the drained lands of the Tver region. Objects of research - potatoes of the Scarb variety, mineral and organic fertilizers in various doses. Organic fertilizers are products of the processing of organic raw materials based on fermentation processes - multipurpose compost (KMN) and BiGuEM. Mineral fertilizers - ammonium nitrate, double superphosphate and potassium chloride. In the work we used experimental methods - field experiments and theoretical research methods - mathematical statistics. Evaluation of the optimal fertilizer doses showed that BiHuEM organic fertilizer at a dose of 3 t / ha, when used together with mineral fertilizers at a dose equivalent to 3 t BiGuEM, provided potato resistance to late blight compared to the version where KMN was used - almost 8% in 2017 and 12% - in 2018, and compared with the option without the use of fertilizers (control) - by 61% and 23%, respectively. This combination of fertilizers provided the maximum yield (both general and marketable) in comparison with the control by 45% when calculating both types of yield in 2017, and in 2018 by 38% of the total and 53% of the commodity yield. A greater increase in potato yield was also revealed in the variant with BiGueM in comparison with the variant of using KMN - by 4.5% and 5.7% in 2017 and in 2018 by 6.1% and 10%, respectively. An increase in the quality of potatoes was noted, which is confirmed by the low content of nitrates in them, as well as by the increased content of starch, which was especially noted in 2017 - 34.3 g / kg and 15.99%, respectively.

ABSTRAK  Kegiatan pengabdian ini bertujuan untuk memberikan pelatihan keterampilan menekan biaya produksi dan meningkatkan pendapatan petani sawi melalui penggunaan pupuk organik cair di Kelurahan Gunung Anyar Tambak Kecamatan Gunung Anyar Kota Surabaya. Pada masa pandemi covid 19 ini pasokan pupuk kimia tersendat dan mengakibatkan harga pupuk semakin mahal. Pada tahun 2010 pemerintah memunculkan wacana global untuk kembali ke alam (back to nature) di sektor pertanian, di antaranya dengan pemanfaatan bahan alam (bahan baku hayati). Untuk itu kegiatan ini memanfaatkan gulma yang terdapat diarea pertanian tumpang sari dimana area pertanian ini terdapat lahan untuk tanaman sawi, jeruk dan jambu kristal namun sebagian lagi merupakan area tambak ikan yang banyak terdapat gulma seperti kangkung liar dan buah yang sudah busuk. Dengan demikian, dilakukan pembuatan pupuk organik cair dengan menambahkan mikro organisme EM4 kepada bahan baku yaitu gulma. Diperoleh hasil bahwa penggunaan pupuk organik cair ini dapat menurunkan biaya produksi dan meningkatkan produktivitas sawi dan hasil pertanian lainnya. Berdasarkan hasil wawancara diperoleh adanya peningkatan pendapatan petani sebesar 22% dari penggunaan pupuk organik cair ini. Luaran dari kegiatan ini adalah produk berupa pupuk organik cair yang dibuat sendiri oleh peserta pelatihan dan meningkatkan motivasi para petani untuk mengembangkan secara mandiri alternatif pupuk organik sesuai dengan kebutuhan. Kata Kunci: Pupuk organik cair, biaya produksi, gulma ABSTRACT This service activity aims to provide skills training to reduce production costs and increase the income of mustard farmers through the use of liquid organic fertilizer in Gunung Anyar Tambak Village, Gunung Anyar District, Surabaya City. During the COVID-19 pandemic, the supply of chemical fertilizers stagnated and resulted in increasingly high fertilizer prices. In 2010 the government raised a global discourse to return to nature (back to nature) in the agricultural sector, including natural materials (biological raw materials). For this reason, this activity utilizes weeds found in the intercropping agricultural area. This agricultural area has land for mustard, citrus, and crystal guava plants but partly is a fish pond area with many weeds such as wild kale and rotten fruit. Thus, a liquid organic fertilizer was made by adding EM4 micro-organisms to the raw material, namely weeds. The results show that liquid organic fertilizer can reduce production costs and increase the productivity of mustard greens and other agricultural products. Based on the interview results, it was found that there was an increase in farmers' income by 22% from the use of this liquid organic fertilizer. The output of this activity is a product in the form of liquid organic fertilizer, which is made by the trainees themselves and increases the motivation of the farmers to develop alternative organic fertilizers according to their needs independently. Keywords: Liquid organic fertilizer, production costs, weeds

Organic fertilizers have recently been gaining popularity; however, their governance is not completely assessed in developing countries. This study investigated the nutrient composition of so-called organic fertilizers in Vietnam’s markets and issues related to their production, and evaluated their potential to contaminate the groundwater. We analyzed the physicochemical properties of 12 domestic and four imported products of the fertilizers, and conducted a cultivation experiment in sandy soil with the fertilizer applied at a rate of 200 mg N kg−1 soil using an automatic watering apparatus in a greenhouse. We further studied the production of an “organic fertilizer” from coffee by-products. The nutrient content greatly varied among domestic products, whereas they were quite similar among imported products. The product packaging of the collected samples lacked information regarding raw materials. Two thirds of the domestic products contained over 30% of the total N in the inorganic form, implying that the N content dramatically increased in the fertilizers rather than in their supposed raw materials. The stages involved in the production were composting, the addition of extra soil as a bulking agent, and the mixing-in of chemical substances to increase the nutrient content before packing. The remarkably high ratio of inorganic N to total N was attributed to excessive N leaching from soil by the application of domestic fertilizers. These results suggested the need for quality criteria guidelines for organic fertilizers in Vietnam that underline not only nutrient levels, but also the control of raw materials and production process of compost, because they are closely related to nutrient uptake and the leaching loss of nutrients.

In recent years, wastes have been reprocessed into useful products, such as organic fertilizer. The application of organic fertilizers in farming practices can produce agricultural products that are safe for human health and the environment. The objective of this study was to investigate the effect of liquid organic fertilizer made from fish waste on the growth of Bali red rice seedlings. A Complete Randomized Design (CRD) consisted of 8 treatments with 5 replications was applied in this experiment. These included immersing of rice seeds in fish waste fertilizer with concentrations of 0.5% = P1, 1% = P2, 1.5% = P3, 2% = P4, 2.5% = P5 and 3% = P6 with volume/volume ratio (v/v), prior to soaking. Rice seeds without immersion in this fertilizer (C0) and those immersed in PGPR bacterial suspension only (C1) served as nil control and control treatments, respectively. The results showed that the application of 2.5% fish waste fertilizer produced the highest results, following measurement of parameters, including the percentage of germination (88.18%), plant height (28.78 cm), and root length (20, 74 cm) on day 15 after sowing.
