Abstract

This study aimed to determine the role of water hyacinth (Eichhornia crassipes Mart.) organic matter on water retention at pF 2.54 and pF 4.2, available water content, and bulk density (BD). The research method used was a factorial randomized block design. The first factor was the sorghum variety, which consisted of 2 levels, namely, V1 (variety) and V2 (Kawali). The second factor was the dose of water hyacinth organic matter, which consisted of 5 levels, namely P0 (without the application of water hyacinth organic matter), P1 (10 tons.ha-1), P2 (20 tons.ha-1), P3 (30 tons.ha-1), and P4 (40 tons.ha-1). Water retention was measured at pF 2.54 and pF 4.2 using a pressure plate apparatus and pressure membrane apparatus, respectively, and BD was measured using the ring method. The results showed that the treatment of organic matter application and varieties had a significant effect on water retention at pF 2.54, available water content, and BD with the best treatment of 40 tons of organic matter application and Kawali variety, but not affecting water retention at pF 4.2. There was no interaction between water hyacinth organic matter and sorghum varieties to improve water retention and BD. The highest water retention at pF 2.54 was 32.24% (P4), and the highest available water content was 11.67% (P4) but not significantly different from P3 (11.55%); the lowest BD was 1.11 g.cm-3 (P4) but not significantly different from P3 (1.13 g.cm-3). A very strong positive linear and negative linear correlation exists between available water content and BD with plant height, panicle length, and sorghum yield. Keywords: bulk density, water hyacinth, water content, water retention, sorghum

Abstract

This study aims to analyze variations in soil physical properties and their implications for corn (Zea mays L.) land management strategies in Pulubala District. This study used a quantitative descriptive survey method on three systematically selected corn land units, with soil sampling at a depth of 0-20 cm for analysis of texture, water content, bulk density, particle density, and porosity in the laboratory. The results showed that points 1 and 3 have a sandy loam texture with a dominant sand content, while point 2 has a clay texture with a dominant clay fraction. The bulk density and porosity values ​​​​illustrate the gradation of soil compaction, where point 1 is relatively looser with high porosity, while points 2 and 3 show lower porosity and indications of compaction that inhibits aeration and root penetration. In terms of management, land with good physical conditions needs to focus on maintaining soil structure, while more compacted land requires intervention in the form of adding organic matter, improving aeration, and regulating drainage to maintain an optimal corn growing environment.

Abstract

Land use change and population growth are the main factors influencing the sustainability of land resource management, particularly in areas experiencing rapid development dynamics. This study aims to analyze the condition and changes in land carrying capacity in Wanggarasi Sub-district using a spatial and temporal analysis approach based on Geographic Information Systems (GIS). The research employs a descriptive quantitative method utilizing secondary data, including population data, land use data, and multi-temporal satellite imagery. The land carrying capacity index was calculated based on several indicators, namely the proportion of the farming population, the area of cultivated agricultural land, farmer involvement in non-agricultural activities, and the availability of land suitable for living. The results indicate that Wanggarasi Sub-district falls into the category of moderate land carrying capacity, with indications of imbalance between the high proportion of the farming population and the limited availability of productive agricultural land and land suitable for living. This condition reflects the presence of socio-ecological pressures that may increase the risk of land carrying capacity deficits if not accompanied by adaptive land management policies. Spatial analysis demonstrates that GIS is effective in identifying the spatial distribution and zoning of land carrying capacity in greater detail. This study is expected to serve as a basis for spatial planning and evidence-based policymaking to support sustainable regional development at the sub-district level.

Abstract

Maize (Zea mays L.) is a significant food commodity in Telaga Biru Subdistrict, Gorontalo Regency; therefore, information on soil fertility is crucial as a basis for effective land management. This study aims to analyze the chemical and physical fertility of soils in maize cultivation areas and to identify efforts to improve maize productivity in Telaga Biru Subdistrict. The study was conducted from April to November 2025 in Telaga Biru Subdistrict, Gorontalo Regency. A descriptive quantitative method with a land unit-based survey approach was employed. Soil sampling was conducted diagonally in three villages: Timuato, Modelidu, and Talumelito, at a depth of 0-20 cm. The analyzed chemical fertility parameters included soil pH, nitrogen, organic carbon, cation exchange capacity, available phosphorus, potassium, and base saturation. Physical soil properties analyzed included soil texture, bulk density, and soil color. The findings showed that the soil pH was slightly acidic, with nitrogen and organic carbon contents falling into the low to moderate categories. The cation exchange capacity and the availability of phosphorus and potassium were moderate, while base saturation was relatively low: The physical soil properties were dominated by clay to clay loam textures with relatively high bulk density values. These conditions indicate that maize cultivation land in Telaga Biru Subdistrict has sufficient fertility to support plant growth; however, appropriate soil management is still required through balanced fertilization, the addition of organic matter, and improvement of soil physical properties to enhance productivity sustainably.

Abstract

Soil fertility is a key factor influencing maize productivity, particularly in intensive agricultural areas. This study aimed to evaluate the chemical and physical soil properties of maize (Zea mays L.) fields in Pulubala District, Gorontalo Regency, Indonesia. The study was conducted from April to May 2025 in three maize-growing villages, namely Mulyonegoro, Puncak, and Molalahu. Soil samples were collected using a diagonal sampling technique at a depth of 0–30 cm. Soil physical properties analyzed included texture, bulk density, and water content, while chemical properties comprised soil pH, organic carbon, total nitrogen, available phosphorus (Olsen P₂O₅), exchangeable potassium, cation exchange capacity, and base saturation. The results indicated that soils in the study area were generally slightly acidic, with low organic carbon, low available phosphorus, and low base saturation, despite moderate nitrogen and high potassium availability. These conditions indicate that low organic matter content and phosphorus deficiency are the main limiting factors for soil fertility in the maize fields of Pulubala District. Integrated soil management practices, including organic matter application and balanced fertilization, are required to improve soil quality and support sustainable maize production.

Abstract

Yardlong bean (Vigna sinensis L.) is one of the secondary food crops with considerable potential as a food source; th erefore, improvements in cultivation practices are required to enhance its productivity. One effort to increase yardlong bean production is through the application of organic fertilizers, such as chicken manure and cattle manure. This study aimed (1) to evaluate the effects of chicken manure and cattle manure application on soil bulk density (BD) and soil color in yardlong bean cultivation, and (2) to determine the optimal dosage of these organic fertilizers for improving BD and soil color. The study was conducted from September to January 2026 in Tunggulo Village, Tilong Kabila Subdistrict, Bone Bolango Regency, Gorontalo Province, Indonesia. The experiment employed a Randomized Block Design (RBD) consisting of five treatments: P0 (control, without fertilizer), P1 (chicken manure at 10 t ha⁻¹), P2 (chicken manure at 20 t ha⁻¹), P3 (cattle manure at 10 t ha⁻¹), and P4 (cattle manure at 20 t ha⁻¹). Data were analyzed using analysis of variance (ANOVA) followed by the Honestly Significant Difference (HSD) test, and correlation analysis was conducted to examine the relationship between BD and the growth and yield of yardlong bean. The results indicated that the application of chicken manure and cattle manure had no significant effect on soil bulk density and soil color.

Abstract

This study evaluated the chemical status of soils under maize (Zea mays L.) cultivation in Tibawa Subdistrict, Gorontalo Regency, Indonesia, to identify fertility constraints and inform site-specific management. A field survey was conducted in May 2025 at three villages (Isimu Utara, Datahu, and Iloponu). At each site, ten subsamples from the 0–20 cm plough layer were composited and analysed for soil pH (H2O and KCl), organic carbon, total nitrogen (Kjeldahl), available phosphorus (Bray I), exchangeable potassium (NH4OAc), and cation exchange capacity (CEC). Results indicated slightly acidic to neutral soils (pH 6.3 - 6.9) with moderate CEC (16.72 - 22.32 cmol(+)/kg). Organic carbon ranged from low to moderate (1.42 - 2.51%). Available P was consistently moderate (12.04–14.72 ppm), whereas exchangeable K was low across all sites (0.19 - 0.24 cmol(+)/kg). Total N varied from low in Isimu Utara (0.13%) to moderate in Datahu and Iloponu (0.24 - 0.26%). The primary limitations for maize production were low K availability and, locally, low N and organic matter. Management should prioritize organic amendments, balanced NPK fertilization based on soil testing, and periodic liming where acidification trends emerge. These findings provide a baseline for future monitoring of soil quality and developing recommendations to sustain maize yields while reducing nutrient losses under intensive management in Tibawa.
