Abstract

Agricultural development, specifically for crops, contributes significantly to national development. However, problems with water and low soil fertility are obstacles to this development. This study evaluated the nutritional status and soil fertility index as the basis for determining the direction of rice field management in Madiun Regency, East Java, Indonesia. The research method was conducted by surveying the soil characteristics followed by laboratory analysis. Soil samples were collected using stratified proportional sampling from 19 land units with 31 samples. The soil fertility index was determined using a principal component analysis test and calculated by dividing the weights by the minimum soil fertility index indicators. The study results show that the nutritional status of total N in the study area is low to high (0.13%–0.59%) and total P is very low to very high (12.18–73.66 ppm), whereas the status of exchangeable K is very low to very high (0.01–0.67 cmol.kg−1), Cation Exchange Capacity is low to high (12.8–36.0 cmol.kg−1), and organic carbon is low to very high (1.98%–6.54%). The soil fertility index ranges from medium to extremely high. The influential indicators are total P, total N, exchangeable K, and organic carbon. It is recommended that the rice field management system implement a “sustainable agricultural intensification” system that combines the two systems “intensification” and “sustainable agroecosystem.” This system still uses proportional inorganic and organic fertilizers (manure, compost, and agricultural waste).

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

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

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.

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

Azolla microphylla as an Alternative Source of Organic Fertilizer in Rice Cultivation on Sandy Soil Field. Rice (Oryza sativa L.) is a commodity that has high economic value in Srigading Village, Sanden District, Bantul Regency. Azolla is a water fern that has high potential as a source of organic fertilizer. The use of azolla as a source of organic fertilizer is not widely known. The partner involved in this activity is Majelis Taklim Nailul Hidayah, which is not economically/socially productive, but its main livelihood is farming, especially rice. The rice cultivation system carried out by partners so far is still based on the conventional system, which utilizes chemical fertilizers. Azolla can serve as a source of organic fertilizers, acting as a substitute for or reducing the need for chemical fertilizers, thereby reducing dependence on them. The activity aims to increase partners' understanding of utilizing azolla for organic fertilizers through azolla cultivation, which is a straightforward process. The method planned for this activity involves explaining the introduction and development of azolla, as well as practicing the technique of multiplying azolla. The stages of the activity included site surveys, hands-on azolla cultivation, and the application of azolla to rice plants in sandy soil. The results showed that the partners already knew how to cultivate azolla, how to apply azolla, and the benefits of azolla on rice growth. Azolla microphylla was cultivated in ponds lined with tarpaulins measuring 2 m x 3 m x 0.5 m, using 0.5 kg of fresh azolla seedlings. Azolla was harvested 2 weekafter sowing, with one pond producing 37.5 kg of wet azolla, representing a 75-fold increase and a productivity of 12.5 kg/m³.

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

Sandy soil has various constraints, such as the low availability of N, P, and K nutrients. Organic matter should be applied to improve soil conditions. This study’s organic materials used as ameliorants included chicken manure and Azolla microphylla. This study aimed to determine the effect of A. microphylla and chicken manure on the availability of micro and macronutrients and rice growth in sandy soil. The research was conducted on the sandy soil of Samas Beach, Bantul, Yogyakarta. The study used a factorial complete randomized block design consisting of 2 factors. The 1st factor is the dose of Azolla (0 and 7.5 tons ha-1). The 2nd factor is the dose of chicken manure (50, 100, 150 tons ha-1). The results showed no interaction between the application of A. microphylla and chicken manure. The application of chicken manure increased NO3-, available P, and available K levels. The application of A. microphylla increased the height of rice plants. Azolla 7.5 tons ha-1 and chicken manure 150 tons ha-1 showed the highest values in NO3- (0.11 mg l-1), available P (6.74 ppm), and organic C (0.27%). Chicken manure of 150 tons ha-1 can increase the number of grains per panicle. These findings offer a potential strategy for addressing nutrient deficiencies in sandy soils and improving rice growth.
