Abstract

Ende Sub-District, East Nusa Tenggara, has various topographies with an altitude of 0-1,100 m asl that can potentially grow Arabica coffee. Still, there is no information available regarding the suitability of the land. This study aims to evaluate the actual land suitability of Arabica coffee based on soil and environmental characteristics. The research method is descriptive explorative through a field survey approach supported by laboratory analysis. Determination of SMU (soil map unit) was carried out by purposive sampling through boring at 31 points, then classified based on soil type to obtain five pedons that represent SMU in Ende Sub-District. Soil sampling was carried out on each layer of each pedon. Data analysis used ANOVA and Pearson correlation tests to determine the determining factors that influence the land suitability class of Arabica coffee. The evaluation results showed that the actual land suitability for Arabica coffee was marginally suitable (S3) and unsuitable (N) classes, with limiting factors, i.e. average temperature, altitude, length of dry period, drainage, base saturation, available P, slope, and erosion hazard. The results of the ANOVA test showed that altitude significantly affected the land suitability class for Arabica coffee, with the best land suitability class at an altitude of 800-1,100 masl. Based on the correlation between land suitability class and land characteristic parameters, the determining factors for land suitability class include average temperature, humidity, drainage, texture, coarse material, total N, available K, erosion hazard, surface rocks, and rock outcrops. Land improvement recommendations are based on making an irrigation system, providing shade plants, N fertilization (urea fertilizer), K fertilization (KCl fertilizer), and terracing.

Abstract

Sediment deposition in the upstream river areas can cause drought and disrupt agricultural activities. This study aims to analyze the potential for drought in the Keduang Sub Watershed based on the Land Map Unit. The Keduang Sub-Watershed area has high potential for the development of agricultural land for food crops, but is not free from the potential for drought. The study was conducted using a soil survey method that was strengthened by soil sampling and laboratory analysis. Parameters for determining soil damage that causes the potential for land drought include soil physical properties, namely specific gravity, structure, soil color, porosity, permeability, slope, and soil type. The results showed that the potential for drought at the research location was still high. This is influenced by the level of soil damage that varies from low, medium to high. Land drought can be an obstacle to agricultural activities, and improper land management can worsen the situation. Conservative actions to overcome this problem include the addition of organic matter, crop rotation, application of soil cover or mulch, and processing agricultural land according to the contour direction. These activities are expected to overcome soil damage so that the potential for drought can be overcome. Keywords: Conservation activities, Land drought, Physic soil properties, Soil damage.

Abstract

The accurate estimation of soil organic carbon stocks (SOCs) is crucial in sustainable oil palm plantation management. Pedotransfer functions (PTFs) serve as an essential predictive tool for enhancing the interpretation and estimation of soil organic carbon stocks (SOCs) and soil porosity. This study aims to improve the precision of SOCs and soil porosity predictions across diverse soil types within oil palm plantations through the application of PTFs. The study was conducted using a survey approach and descriptive exploration in an oil palm plantation in Seruyan District, Central Kalimantan. The study area encompassed four distinct soil types (Alfisols, Inceptisols, Ultisols, and Entisols), with six replicates for each soil type. Soil samples were collected from a depth of 0–60 cm. Statistical analyses included ANOVA, Tukey’s pairwise comparisons, correlation, and stepwise regression. The results indicated that soil types within oil palm plantations did not significantly affect SOCs but significantly impacted soil porosity. SOCs and porosity estimated using PTFs were lower than those estimated without PTFs. Specifically, SOCs analysis with PTFs ranged from 3.4 to 7.1 kg m-²; without PTFs, the range was higher, between 8.1 and 10.9 kg m-². Among the soil types, Entisols exhibited higher porosity with PTFs (51.3%), while Ultisols had the lowest porosity (37.9%). The PTFs provide better predictions for SOCs and porosity, and predictor variables that contribute the most are sand, silt, bulk density (BD), and cation exchange capacity (CEC). PTFs provide an advanced, data-driven approach to assessing SOCs and soil porosity in oil palm plantations, supporting the development of smarter, sustainable, and highly efficient management strategies.

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

The uncertainty in precipitation patterns resulting from climate change may contribute to uncertainties in the growing seasons and productivity of rice and other agricultural commodities. This study aimed to examine the changes in precipitation and cropping patterns across various topographic sequences of volcanic regions in Central Java, Indonesia. Precipitation data from 33 rainfall stations across three topographic sequences (0-400 meters, 400-700 meters, and above 700 meters above sea level, categorized as high, mid, and lowlands, respectively) were analyzed to understand cropping patterns using both quantitative and qualitative methods. The findings revealed that farmers' actual cropping patterns were not primarily influenced by precipitation levels but rather by soil suitability. Moreover, the frequency of drought occurrences, as indicated by the Standardized Precipitation Index (SPI), did not significantly impact cropping patterns or crop yields. Instead, agricultural yields were found to be dependent on irrigation infrastructure rather than precipitation levels. This study sheds light on the importance of adaptation and mitigation strategies to address the adverse impacts of climate change on agricultural management across different topographic sequences.

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

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.
