Abstract

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.

Abstract

Successful management of saline water could have significant potential for agricultural development in many areas, particularly in freshwater-scarce regions. To date, the effect of salinity on shallot (Allium Cepa L.) yield and growth parameters has not been studied in detail specifically for local varieties cultivated in Inceptisols. Therefore, the present study was designed to evaluate the effects of different levels of irrigation-water salinity (0, 1, 2, and 3 dSm-1) on soil chemical properties, the growth, and yield of local shallot varieties. The experiment was conducted in pots using a randomized plot design with two factors and three replications. The results showed that increases in salinity level affected increases soil pH, exchangeable Na percentages, and plant height growth. Nevertheless, bulb number and weight, soil exchangeable Ca and Mg, soil organic carbon, and sodium adsorption ratio (SAR) was not significantly affected. The findings of the present study suggest that the local varieties—Brebes and Purbalingga—with irrigated salinity levels up to 3 dSm-1can be tolerated for shallot cultivation in Inceptisols.

Abstract

One of the organic farming goals is improving soil properties to support sustainable rice production. This study investigated the soil properties and rice yields under temporal variation of organic rice fields. Soil sampling was conducted in organic rice fields with three temporal variations, namely 0, 4, 7, and 10 years in a tropical monsoon region in Central Java, Indonesia. Variables observed included soil organic carbon, soil carbon stock, soil microbes population, dissolved organic carbon, soil liquid limit, soil sticky limit, soil plasticity limit, soil color changing limit, soil friability, soil porosity, soil total nitrogen, soil total phosphorus, soil available sulfur, exchangeable calcium, cation exchange capacity, total potassium, bulk density, base saturation, exchangeable sodium, exchangeable potassium, and rice yield.  This study confirms that soil organic carbon increased by 51.63% within 10 years (from 1.84% to 2.79%). Organic farming also improved all the physical, chemical, and biological soil properties, by the increase of soil organic carbon. However, soil organic carbon is mostly determined by soil cation exchange capacity, soil total phosphorus, and soil porosity. The mechanism of rice yield increase in organic rice farming is not affected by soil organic carbon directly but through the synergic increase in soil total nitrogen. The 1% increase of soil organic carbon increases 0.065% of soil total nitrogen hence rice yield increases by 1.66 tons ha-1. This study supports sustainable agriculture by providing evidence of improved soil properties under organic farming.

Abstract

Agricultural constraints on sandy soil are poor chemical characteristics and low biological activity resulting in the soil becoming less productive to be planted. One of the efforts to improve the quality of sandy soil are application of mycorrhizae and a soil ameliorant. The purpose of this study was to determine the effect of mycorrhizae and a soil ameliorant on soil chemical characteristics and soil biological activity. The experiment was arranged using a Complete Randomized Design that had two factors. The first factor (1) was mycorrhizae dose, without mycorrhizae (M0) and six spores of mycorrhizae/plant (M1), and the second factor (2) was types of soil ameliorant, without ameliorant (S0), cow dung (S1), rock phosphate (S2), biochar (S3), cow dung–rock phosphate (S4), cow dung–biochar (S5), and rock phosphate–biochar (S6). The results indicated that combination of six spores mycorrhizae/plant–cow dung 60 tons ha−1–biochar 25 tons ha−1 (M1S5) increased soil organic carbon (SOC) (235%), available P (675%), cation exchange capacity (CEC) (216%), total glomalin (101%), and easily extracted glomalin (69%), decreased exchangeable sodium percentage (66%), and increased absolutely for root infection and spore density than without mycorrhizae and a soil ameliorant (control). The lowest of SOC in non-mycorrhizae and rock phosphate, available P, CEC, root infection, spore density were found on the control, but the lowest of total glomalin and easily extracted glomalin were found on non-mycorrhizae–rock phosphate. The application of mycorrhizae, cow dung, and biochar improved the sandy soil characteristics.

Abstract

Nitrogen is one of the primary nutrients required for growing rice. Still, the efficiency of urea fertilizer application is very low (20-40%) due to the nitrogen loss process, one of which is denitrification. This study aims to determine the effects of combining Microbial Fuel Cell (MFC), plant spacing, and fertilization on nitrogen dynamics in paddy fields. The combination of treatments are expected to reduce the nitrogen loss in paddy fields, and plants can absorb it efficiently. A total of six treatments included Microbial Fuel Cell (MFC) (2 levels: without MFC and with MFC), plant spacing (2 levels: conventional spacing 25 cm × 25 cm and jajar legowo spacing 25 cm × 12.5 cm × 50 cm), and fertilization (2 levels: without fertilizer and with 500 kg ha-1 of NPK fertilizer), with three replications for each combination. The observed parameters included total soil nitrogen, nitrate, nitrogen uptake, chlorophyll, nitrogen-fixing and denitrifying bacteria, and N2O gas emissions. The results showed that combining MFC, conventional spacing, and NPK fertilizer in the paddy fields resulted in a high total soil nitrogen (0.44%). The results showed different effects on total soil nitrogen in the MFC and fertilization treatments, leading to increased nitrate levels, nutrient uptake, and chlorophyll. Increasing total soil nitrogen significantly contributes to leaf development and significantly aids photosynthesis. The integration of MFC and fertilization observed in this study resulted in a real impact on nitrogen dynamics in paddy fields. This combined treatment effectively reduces total nitrogen loss due to denitrification in paddy fields, thereby increasing the efficiency of uptake by plants.

Abstract

Vermicompost is the product of organic matter decomposition by earthworms and has great potential as an environmentally friendly fertilizer. It contains natural growth hormones, enzymes, and active microorganisms, and is free from harmful pathogens and heavy metals, making it safe for both soil and plants. Alfisol soils, which are typically low in organic matter and essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), require organic inputs to improve their fertility. This study aimed to evaluate the effects of vermicompost and manure on nutrient availability and sweet corn yield in Alfisols. The experiment was conducted using a completely randomized block design with treatments combining various doses of vermicompost and manure. Observed parameters included soil chemical properties, plant growth, and yield components. The results showed that the application of vermicompost at a dose of 1 ton/ha was not significantly different from 2 tons/ha of manure, but both treatments differed significantly from the control. The combined treatment of NPK and vermicompost (1 NPK + 2 vermicompost) increased nutrient availability and uptake, as well as sweet corn yield (total N: 0.68%, available P: 7.76 ppm, available K: 1.78 me/100 g, cob weight: 240.5 g). These findings confirm that vermicompost, as an organic nutrient source, is effective in supporting sustainable agricultural practices in marginal soils such as Alfisols, while reducing dependence on inorganic fertilizers.

Abstract

The nutrients of plants and the physical condition of the soil must both be considered to increase corn productivity. The continuous use of inorganic fertilizer without manures will cause a decrease in the physical properties of the soil. Therefore, this study aims to obtain doses of organic fertilizer from cow manure and inorganic fertilizers namely urea, KCl and SP-36 that will give the best effect on the physical properties of Alfisols, growth and yield of hybrid corn. The experiment was carried out using the randomized complete block design (RCBD) with two factors namely organic and inorganic fertilizers. Each factor was given at four dosages: 1, ¾, ½ and ¼ of the standard dose each with three replications. Observation parameters include bulk and particle density, soil porosity, aggregate stability, root volume and fresh weight, plant height, as well as the weight of corn with and without husks. The results showed that organic and inorganic fertilizers significantly affected bulk density, soil porosity, aggregate stability, root fresh weight, root volume, as well as the weight of corn with and without husks. Additionally, treatment with 7.5 to 10 tons of organic fertilizer as well as ¼, ¾ and 1 dose of inorganic fertilizers produced the best effect on soil physical properties of Alfisols, growth and yield of hybrid corn, while the lowest results were obtained in the control treatment. This indicates that organic treatment can reduce the use of inorganic fertilizers between ¼ to ¾ of the standard dose.

Abstract

Inceptisol soil has an acidic pH, low organic content, and low P elements. Biochar and other types of fertilizers are needed to improve soil fertility. This research was conducted to determine the effect of the best dose of biochar and the kind of fertilizer on rice plants' growth and P uptake. There were 16 treatments with 3 repetitions. The dosage of rice husk biochar consists of doses of 0 t.ha-1 (B0), 5 t.ha-1 (B1), 10 t.ha-1 (B2), and 20 t.ha-1 (B3). Types of fertilizer consist of 0 t.ha-1 (P0), 4 t.ha-1 manure (P1), 50% urea + 50% NPK fertilizer + 2 t.ha-1 manure (P2), and 100% urea + 100% NPK fertilizer (P3). Parameters observed were available P, P tissue, P uptake, plant height, number of tillers, and dry weight brazier. Data analysis was performed with the ANOVA, DMRT, and Correlation tests. The result showed the dosage of rice husk biochar and the type of fertilizer affected the yield of rice plant height, number of rice tillers, stover dry weight, and P uptake. P3 treatment produced the highest plant height, which was 104,68 cm. The B3 and P3 treatments produced the highest of rice tillers. The B3P3 interaction treatment resulted in the highest root tissue absorption of 1,93 g.clamp-1 and 3,49. clamp-1 in the mature.

Abstract

The use of Azolla microphylla (Azolla) as organic fertilizer or green manure is not yet known by the Farmer Group (FG) of Tani Mulyo 1 and Tani Mulyo 5. Moreover, dual system of Azolla is applied to organic rice cultivation. The dual system of Azolla uses Azolla as a fertilizer and as a deterrent to the growth of weeds that interfere with rice plants. This partnership program aims to increase partners' knowledge about the dual system of Azolla and assistance and direct practice of Azolla application on cultivated organic paddy fields. The stages include socialization, counseling, mentoring, practice of Azolla application, and monitoring-evaluation. The results showed that the participants' knowledge about Azolla before the activity was 25% very not know, 45% not know, and 15% know enough. There was an increase in participants' understanding after the activity, 65% know and 25% very know or increased up to 100% compared to before the activity. The results of participant satisfaction showed that 65% of participants were satisfied and 10% are very satisfied with the activities carried out. As many as 70% of the partners stated that they would apply the dual system of Azolla in organic rice cultivation. The increasing understanding and awareness of partners will affect the development of organic rice cultivation.

Abstract

Azolla merupakan tumbuhan paku air dengan kelebihan memiliki sifat yang cepat dalam proses berkembang biak serta dapat digunakan sebagai pupuk organik dalam bentuk kompos atau pupuk hijau, namun belum banyak dikenal dikalangan petani, khususnya kelompok Tani Makmur dan Margo Mulyo di dusun Nayan, Nangsri, Kebakkramat. Permasalahan utama pada kelompok tani tersebut adalah minimnya pengetahuan dan informasi mengenai budidaya Azolla dan pemanfaatan azolla sebagai sumber pupuk organik serta penerapan pupuk organik ini pada lahan pertanian. Tujuan dari kegiatan ini adalah mengenalkan Azolla ke kelompok tani, melatih budidaya Azolla dan mengevaluasi penerimaan petani terhadap pengembangan pertanian organik yang ramah lingkungan, dan mengurangi ketergantungan penggunaan pupuk anorganik atau sintetik dengan memanfaatkan Azolla sebagai sumber daya alam lokal. Kegiatan yang dilakukan dalam melaksanakan pengabdian ini antara lain : Survei lokasi dan waktu pelaksanaan, Edukasi/paparan dan sosialisasi tentang manfaat azolla, Pelatihan budidaya dan pendampingan aplikasi azolla, Focus Grup Discussion (FGD). Metode pengabdian dilakukan melalui penyuluhan, pelatihan dan evaluasi kegiatan dalam pengembangan pertanian organik yang ramah lingkungan menggunakan sumberdaya lokal yaitu azolla. Pengetahuan petani tentang Azolla dan manfaatnya sebagai sumber pupuk organik sebelum dilakukan penyuluhan masih rendah atau <20% yang baru mengetahui manfaat dari azolla. Setelah dilakukan kegiatan, pengetahuan dan pemahaman petani tentang potensi dan manfaat budidaya azolla meningkat serta ketertarikan petani terhadap budidaya azolla secara mandiri mencapai 90%. Azolla merupakan sumber pupuk organik yang dapat menekan penggunaan pupuk anorganik atau sintetik.
